They are widely used in aerospace, automotive and construction fields. However, the above steel parts are prone to be susceptible to hydrogen embrittlement, corrosion and other aging phenomena, resulting in the reduction of the flight safety factor. In this work, based on the actual situation of corrosion of the cadmium plating layer of cargo door rods and boarding gate/service hatch door rods, the cadmium acetate (short for (CH3COO)2Cd) leads to the failure of the jam nuts and locking device assembly, the cause and mechanism of the corrosion in the storage environment are analysed. Compared with the slightly corrosion jam nuts (19.18 kN and 370 HVI), the tensile property and hardness of the jam nuts with serious corrosion respectively decreased to 17.39 kN and 417 HVI, by 10.10% and 3.8%, which will reduce performance impacts on the safe flight and daily maintenance of aircraft. By improving the warehouse storage environment and operators’ specification documents, these problems have been avoided, and experience has been provided for parts anti-corrosion and batch production of airliner route operation.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"54 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141803706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, sacrificial anodes are often undersized or improperly positioned. This study systematically investigates how anode design factors affect the CP effectiveness through computational modelling and double-objective optimisation techniques around the optimum location and dimension of anodes. State-of-the-art algorithms including the Monte-Carlo, Nelder–Mead, co-ordinate search, constrained optimisation by linear approximation (COBYLA) and bound optimisation by quadratic approximation (BOBYQA) are employed to optimise anode locations and genetic algorithm is utilised for optimising anode dimension and the objective is maximising the current output and minimising the cost. In the current study, the BOBYQA technique proved efficient in reaching the optimal response at the appropriate time. The findings indicate that in double-objective (cost and potential) optimisation of 14.5 kg anode, minimising anode radius (from 6.5 cm to 5.4 cm) and optimising the position boosts the current output by up to 15.5%. Refined anode geometries increase the average structure potentials (806 → 822 mV) by over 15 mV, translating to extended service lifetimes. In the comparison of single (cost) and double (cost and potential)-objective optimisation, about 15% more current reaches the structure and causes about 2% less anode mass loss for the same anode dimensions. Also, the results show the 7.7 kg anode performs better than the 14.5 kg anode and so output current and the percentage of current that reaches the structure of the 7.7 kg and 14.5 kg are 0.66 A and 0.46 A and 66% and 60%, respectively.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"98 41","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results of the study revealed that under acidic environments B. coagulans formed a protective biofilm on MS surface and caused marked reduction in corrosion and other forms of mutilation. Characterization and electrochemical procedures were performed to investigate the inhibitory effects of B. coagulans at different pH and at different temperatures on the corrosion rate and, to determine the mechanism of corrosion prevention. The film developed on surface of the MS by B. coagulans, was crack free, compact, and lipophilic in nature and was composed of amyloid fibers, carboxylic acid, and proteins that make electrochemical reactions that, accruing on the metal–solution interface difficult and substantial reduction in corrosion rates observed. The film adhered to the surface of metal substrates shows fitting with diverse adsorption isotherm indications, with physical adsorption being the predominant pattern observed in most cases. This suggests that the interaction between the biofilm and metal surfaces is primarily governed by physical forces. To conclude, B. coagulans exhibits protective action on MS against corrosion.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"39 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two applications of 2AP are considered i.e., preventive (applied before exposure to aggressive environment) and repair (applied after corrosion initiates). Corrosion performance was assessed using electrochemical techniques and gravimetric mass loss method. The study also examines the impact of 2AP application on chloride ion concentration and carbonation depth of both concrete systems. The compressive strength of each concrete system was also measured to study the impact of M-CoI application on strength properties. Surface condition of hardened concrete and extracted rebar was evaluated by optical microscopy. Results conclude that 2AP effectively retards reinforcement corrosion when used as preventive measure by forming a homogeneous inhibitive layer on steel. However, when used as a repair technique, localised and uniform corrosion was perceived. An attempt has been made to identify the cause of non-performance of 2AP as repair measure. It was concluded that reached concentration of 1 mM was not sufficient to reduce ongoing corrosion due to the accumulation of corrosion products. The influence of the inhibitor on chloride profile and carbonation depth was found to be insignificant. It is concluded that chloride ions initiate the corrosion mechanism, while carbonation exacerbates it, particularly in blended cement concrete. Nonetheless, inhibitor application can provide similar resistance in both concrete systems.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"23 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141112601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is concluded that there would be greater opportunities for the gravitational field-induced method to play the shielding effect of graphene; noncovalent modification methods may not ensure satisfactory attachment of the modifiers to the surface; green modification methods are expected to reduce the electrical conductivity of graphene and covalently modify graphene; the self-healing and early-warning graphene-based anticorrosive coatings are becoming a trend in the development of anti-corrosive coatings. The current-faced challenges and the future development prospects of the graphene-based anticorrosive coating were also proposed. Although graphene performs well in anticorrosive coatings, there is still considerable room to improve the performance, and a new round of industrial optimisation and upgrading in the anti-corrosion coating industry is inevitable with the rapid development of the anticorrosive graphene-based filler.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"13 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140974394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, the oxidised films were modified using surfactants such as decanoic acid (DA), decyl silane triol (DS) and perfluorodecyl silane triol (FDS), resulting in the creation of three distinct films exhibiting superhydrophobic properties. The effects of the hydrophilic and hydrophobic groups of surfactants on the superhydrophobic films of X80 steel were analysed using electrochemical methods, surface analysis techniques and theoretical calculations. The results showed that all three superhydrophobic films exhibited excellent corrosion resistance, with the order being DA > FDS > DS after 72 h of immersion in acidic conditions (pH = 6, 60 °C). Theoretical calculations showed that the adsorption performance of carboxyl groups was superior to that of silyl alcohol bonds, whereas fluorination of hydrophobic groups helped to enhance the adsorption capacity of hydrophilic groups. This not only reveals the key role of surfactants in the preparation of superhydrophobic membranes but also provides a theoretical basis for the preparation of superhydrophobic membranes on carbon steel surfaces.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141007428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
