It has been investigated the effects of 5-(5-(3,5-diaminophenyl)-1,3,4-oxadiazol-2-yl)-N1,N3-di-p-tolylbenzene-1,3-diamine (BATP) on mild steel in 1 M H2SO4 at 30 °C, Levamisole (LMS) and 4-phenylimidazole (PIZ) on copper in 0.5 M H2SO4, 2-phenyl-1, 4-dihydroquinoxaline (PHQ) on carbon steel in 1.0 M HCl. Based on DFT calculations in the 6–311++G(d,p) basis set in gas and aqueous phases, several quantum chemical parameters were determined to evaluate the array of selected molecules such as HOMO, LUMO, ionization energy, bandgap energy, electronegativity, chemical potential, electrophilicity, nucleophilicity, electron transfer, back-donation energy and Fukui function analysis. The most stable low-energy adsorption configurations of the materials employed in this investigation on the Fe (110) surface were induced using Monte Carlo simulations.","PeriodicalId":10721,"journal":{"name":"Corrosion Reviews","volume":"41 1","pages":"427 - 441"},"PeriodicalIF":3.2,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45411053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrogen can dissolve in the steel and cause hydrogen embrittlement (HE), compromising pipeline structural integrity. HE causes subcritical cracking, decreases ductility and fracture toughness, and increases the fatigue crack growth rate (FCGR). This work analyzes the testing standards in gaseous hydrogen used to quantify those effects. Design code ASME B31.12 applicable to hydrogen pipelines has more stringent requirements than ASME B31.8 code commonly used for constructing natural gas pipelines. Differences in materials requirements specified by those codes are summarized. ASME B31.12 pipeline code applies for H2 at a concentration greater than 10% molar. However, recent testing programs acknowledge that H2 degrades steel mechanical properties regardless of its percentage in the blend. This paper discusses how the hydrogen degraded mechanical properties affect pipeline integrity. Decreased mechanical properties cause a drop in the failure pressure of a flawed pipeline, calculated following a fitness for service methodology. There is an increasing risk of subcritical crack growth in H2 as the hardness of base metal and welds increases. This paper analyzes where zones with high hardness and susceptible microstructures are expected in existing pipelines.","PeriodicalId":10721,"journal":{"name":"Corrosion Reviews","volume":"41 1","pages":"319 - 347"},"PeriodicalIF":3.2,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47300251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its importance has been increasingly acknowledged because of the high cost and potential danger of causing severe losses. This review gives essential knowledge of CUI and summarizes the research from several aspects, including lab experiments, field tests, CUI prediction methods and numerical simulation research in porous materials. Insulation material, coating, substrate metallic material of the equipment, operating temperature and surroundings are some critical factors that should be considered in the CUI problem. Experimental research methods of CUI and mass transfer in insulation materials were summarized, as well as the applications of data science in CUI prediction. This review also focuses on simulation researches on heat and moisture transfer in porous insulation materials since numerical simulations are helpful for establishing validated models for CUI by modeling to describe the specific processes and predict environmental conditions of CUI for further corrosion research. Combined experimental and simulation work of CUI would be a practical and effective method for CUI research.","PeriodicalId":10721,"journal":{"name":"Corrosion Reviews","volume":"41 1","pages":"263 - 276"},"PeriodicalIF":3.2,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47906863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their chemical structure consists of a 5-membered heterocyclic ring (C3N2H4) with two nitrogen atoms that are readily adsorbed onto metal surfaces. Also, a pendant side chain or alkyl amine substituent acts as an anchor that helps to maintain its adsorption on steel surfaces. The tail portion is a long hydrocarbon chain that can form a hydrophobic film on a surface. These molecular structures make it very attractive as a starting point for several enhancements in corrosion inhibition research. Moreover, modification of an imidazoline structure can be more effective in enhancing its effectiveness in corrosion inhibition. This review compiled all information regarding imidazoline and imidazoline derivatives used as effective corrosion inhibitors in the petroleum industry. It includes their chemical structures and properties, synthesis processes, characterisation and performance evaluations.

As the concrete has negligible tension strain capacity, in the absence of confinement, anchorage failure occurs by cover splitting and consequent bond deterioration. This paper presents an experimental study of short reinforcement anchorages embedded in a strain resilient cementitious composite matrix, which were preconditioned under simulated corrosion before mechanical loading. The experiment was meant to assess the restraining effect of randomly dispersed plastic fibers on the build-up of expansive rust, by measuring the degree of rebar corrosion that led to cracking of the concrete cover, and the consequent improvements in residual anchorage capacity, by measuring the mechanical response to four-point loading. A total of eighteen short beams were tested with variables being the anchorage length extending into the shear span of the beams as well as the matrix (with and without fibers). Comparisons among artificially corroded and non-corroded coupons demonstrate the favorable effect a strain resilient matrix has in delaying metal consumption as a consequence of the fibers’ restrain against crack initiation/widening; their mechanical testing reveals even increase of local bond strength for corrosion level less than 10%.","PeriodicalId":10721,"journal":{"name":"Corrosion Reviews","volume":"41 1","pages":"201 - 212"},"PeriodicalIF":3.2,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45486723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FeCrAl alloys have good mechanical properties at temperatures of 300 °C and higher, and have superlative resistance to attack by steam at temperatures of up to 1000 °C and higher. A concern has been raised that the use of FeCrAl for cladding would result in a higher content of tritium in the reactor coolant as compared with the current system where the cladding is a zirconium based alloy. This review shows that the flux of tritium from the fuel rod cavities to the coolant across the fuel cladding wall will be greatly reduced by the presence of oxides on the surface of the cladding. The review of current literature and permeation data show that (a) protective oxides are expected to be present on both sides of the FeCrAl cladding, and (b) depending on the characteristics of these oxide layers it is reasonable to expect about two–three orders of magnitude reduction in tritium permeation, relative to the permeation response in clean, unoxidized condition for FeCrAl steels of interest, around 277 °C–377 °C temperatures.","PeriodicalId":10721,"journal":{"name":"Corrosion Reviews","volume":"41 1","pages":"143 - 169"},"PeriodicalIF":3.2,"publicationDate":"2023-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44054362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The repassivation potential of the tested alloys as a function of temperature and chloride concentration was given by E R,CREV = (A + BT)log[Cl−] + CT + D for a range of environmental conditions. When temperature and chloride concentration increased E R,CREV showed a lesser dependence on the environmental variables. The repassivation potential of Ni–Cr–Mo–(W) alloys was described by a new proposed equation in terms of [Cl−], T, Cr, Mo and W, alloys in wt%. The dependence of E R,CREV with the weight % of main alloying elements was 5–6 mV/%Cr, 17–18 mV/%Mo and ∼9 mV/%W, at 85 °C in chloride solutions. An optimal main alloying elements relationship was noted that maximizes the E R,CREV value. The optimal alloy ratio would be 1:3.3:1.65 for wt%Cr, wt%Mo and wt%W, the same factors as in the PRE equation. The optimal alloying ratio would be independent of the alloy composition since it is not a function of the content of main elements.","PeriodicalId":10721,"journal":{"name":"Corrosion Reviews","volume":"41 1","pages":"213 - 224"},"PeriodicalIF":3.2,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48325727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

XRD, SEM/FESEM and EDS were used to characterize the micro-morphology and elemental composition of HDGS. Immersion corrosion test, Tafel polarization and EIS test were carried out to study the effect of compound inhibitor on the corrosion resistance of HDGS in the marine environment. The best proportion of compound inhibitor was added to the self-made waterborne polyurethane coating (WPUC), aiming to evaluate its influence on the coating performance in the marine environment by immersion corrosion test and EIS test. The results showed that Na2MoO4, as a passivation type corrosion inhibitor, bounded Zn at the active sites of HDGS coupons and created structural defects. Benzimidazole, as an adsorption type corrosion inhibitor, was attracted by electricity and adsorbed at the structural defects. Under the premise of 1 wt% total content, the optimal ratio of Na2MoO4 & benzimidazole was 9:1 and the corrosion inhibition efficiency was 99.62%. The corrosion current density of HDGS in the simulated seawater with compound inhibitor was 5.650 × 10−8 A/cm2, while that of HDGS in the simulated seawater without compound inhibitor was 1.483 × 10−5 A/cm2. The WPUC containing compound inhibitor had a small decrease in corrosion resistance due to defects created by doping at the beginning of immersion, then the compound inhibitor would play an active role in the corrosion process to make more than double the service life of WPUC.","PeriodicalId":10721,"journal":{"name":"Corrosion Reviews","volume":"41 1","pages":"225 - 235"},"PeriodicalIF":3.2,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44548302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
