Water-based lubricants have been proposed for a marine application due to their environmental acceptability and their potential benefits when they are used in oil-to-sea interfaces minimizing the issues related to seawater contamination. The effect of normal load and speed on friction was studied for all seal-coating candidates. Hydrogenated acronitrile–butadiene rubber (HNBR) and ethylene–propylene–diene rubber (EPR) seals resulted in higher coefficient of friction (CoF) compared to ultra-high molecular weight polyethylene (UHMWPE), aliphatic polyketone (PK) and synthetic woven fabric impregnated with phenolic resin (SWF) plastic seals. This was attributed to the higher real contact area generated by the softer rubber seals compared to the harder plastic seals at the same normal load. From the point of view of the tribosurfaces tested in this work (hardened steel, WC-CoCr, Cr<sub>3</sub>C<sub>2</sub>-NiCr and SiC-YAG), friction and wear were controlled by two different mechanisms depending on the type of tribosurface. For metallic surfaces, the friction modifiers in the lubricant were adsorbed on the metals and controlled the frictional performance. The hardened steel (100% metallic surface) showed the lowest CoF, followed by the two cermet coatings (21-23 vol.% of metallic binder). The SiC-YAG coating (ThermaSiC) showed the best friction and wear performance due to the formation of a hydrated film on the SiC phase (77 vol.% of the surface) despite not having any metal matrix.</p></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"34 2-3","pages":"956 - 969"},"PeriodicalIF":3.2,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11666-024-01891-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the oxides introduced during spraying process have an adverse impact on the performance of the MCrAlY coatings. In the present work, an attempt was made to deposit NiCrAlY coatings by air plasma spraying (APS) with a low oxide content achieved by introducing diamond into NiCrAlY powders through ball milling as a carbon deoxidation element. During spraying, the carbon is preferentially oxidized and the formed gaseous CO is completely removed rapidly. Thus, the in-flight oxidation of main metal elements can be suppressed. Individual droplets in-flight were collected using liquid N<sub>2</sub> to elucidate the deoxidation effect. The coatings were deposited at different spray distances to examine the oxidation behavior. Results showed that the oxide content of NiCrAlYC particles is 0.43 wt.%, being much lower than the 2.87 wt.% of conventional NiCrAlY particles. The oxygen content of APS NiCrAlY coatings presented a decreasing tendency with increasing spray distance. All results reveal that the NiCrAlYC droplets without oxidation of Ni, Cr and Al can be achieved by adding 4 wt.% deoxidation element carbon. The low oxide inclusions contributed to the formation of dense NiCrAlYC coatings with a porosity of about 0.3% and the significantly improved inter-lamellar cohesion and the adhesion between the coating and the substrate. The tensile tests reveal that the APS NiCrAlYC coatings achieved an adhesive strength higher than 71 MPa. Thus, it is an effective approach to deposit NiCrAlY coatings with excellent performance by APS through design of NiCrAl-based powders containing carbon as a deoxidizer.</p></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"34 2-3","pages":"823 - 834"},"PeriodicalIF":3.2,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, it can also simulate material exposure in real applications, e.g., in solar power plant. In this study, the possibility of using concentrated solar power to test the performance of TBCs prepared by hybrid water/argon-stabilized plasma technology was studied for the first time. Testing procedure was carried out in three stages. In stage I, the procedure was optimized for multilayered TBC and then one selected condition was used in stage II and stage III also for hybrid TBCs. In service, TBC top-coat layer may be exposed also to so-called CMAS air-borne particles occurring in the atmosphere which may melt at elevated temperatures and penetrate the coating microstructure, inducing crystallographic and volumetric changes therein. Therefore, testing with the presence of CMAS particles was also included in this study to observe its influence on the coating microstructure under solar irradiation for potential environmental barrier coatings applications, e.g., solar power plants in desert areas. Changes in the coating microstructures were studied using SEM analysis and X-ray diffraction. The interaction of the coatings with melted CMAS particles was observed using EDS analysis. The results show that the CSP may be a suitable method for TBCs testing, if provided with several adjustments, especially regarding temperature control and measurement. In general, the tested TBCs withstood the CSP testing without significant morphological changes when tested without CMAS particles, while suffered from severe damage during the CSP testing with CMAS particles applied on the surface.</p></div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"34 2-3","pages":"795 - 808"},"PeriodicalIF":3.2,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the cons for industrial use of CS or CSAM is their higher costs compared to the traditional coating or manufacturing processes. Reducing the feedstock powder consumption by maximizing the deposition efficiency has been the focus of many works. However, depending on the part geometry (e.g., a plate with holes), and CSAM strategy with low deposition efficiency, a considerable mass of powder can pass through the substrate, failing to bond, and becoming a process waste. This work evaluates CS 316L stainless steel coatings, recovering the unbonded particles and reusing them in a later deposition, thus making coatings with reused powders. The original and recovered powders were characterized in terms of particle shape and size distribution, phase composition, microhardness, and other properties to evaluate the evolution of the particles' properties due to the recovery process. Besides the powders, the CS coatings obtained with original and recovered powders were evaluated through cross-section image analysis, where porosity, deposition efficiency, and microhardness were observed. The results indicate that the powders' physical properties undergo variations over multiple deposition cycles without significantly affecting the quality of the CS coatings, with porosity below 1.5% and microhardness around 350 HV<sub>0.3</sub> in most cases.

Substrate material, shape and size were varied, resulting in a range of substrate process temperatures as evaluated using IR camera measurements. Deposits sprayed on the smallest parts, i.e., those displaying the highest temperatures, exhibited lower hardness due to spontaneous in situ annealing caused by the thermal energy rise intrinsic to the cold spray process. Smallest parts also presented the best ductility from a combination of spontaneous in situ annealing and improved interparticle cohesion. The as-sprayed deposit strength was rather optimized at an intermediate substrate size and temperature where partial spontaneous in situ annealing was combined with improved interparticle cohesion. After deposit heat treatment, differences among tested substrate sizes vanish. Deposit heat treatment at 350 °C causes softening, a decrease in strength and an increase in ductility due to the annealing effect. The sintering effect becomes predominant for deposit heat treatment at 600 °C, leading to an increase in ultimate tensile strength and further improvement in deposit ductility.
