One solution is to apply protective coatings whose composition is less reactive with the molten aluminum and improve its hardness, toughness, wear, and corrosion resistance, thus prolonging its service life. This work evaluates the effectiveness of Ti-6Al-4V coatings deposited by twin wire arc spraying in an air or nitrogen atmosphere. Nitrogen was used as the carrier and shielding gas for the in-flight molten particles. Coatings were deposited by varying the stand-off distance, the nitrogen gas pressures, and the substrate temperature. The microstructure of the coatings is interlayered, one porous layer of dendrites and one highly densified layer. The presence of TiN, TiO2, α-Ti, and β-Ti phases was confirmed by different characterization methods. For instance, x-ray photoelectron spectroscopy measurements confirmed the presence of N-Ti, O-Ti, and N-O bonds, with the oxygen/nitrogen/titanium percentage associated with the formation of a non-stoichiometric (Ti, Al, V)NxOy phase. Finally, the reactivity of selected oxynitrided Ti-6Al-4V coating in contact with molten aluminum showed a low reaction rate compared to the coarse reaction layer suffered by the uncoated steel substrates.</div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"33 8","pages":"2801 - 2814"},"PeriodicalIF":3.2,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11666-024-01881-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845010","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}

This leads to the lower conductivity of the coating compared to the sintered bulk, and results in increased ohmic resistance and reduced output performance. To improve the interface bonding and conductivity of plasma-sprayed La0.2Sr0.8MnO3-La0.3Sr0.7TiO3 (LSM-LST) bilayer interconnects for tubular cells, a Co3O4 healing additive was added to the gap interfaces within the LST and LSM coatings.

Moreover, the gas leakage rates of the stable coatings after interface healing were > 1 order of magnitude lower than that of the as-sprayed coatings.

The results show that the coating is composed of γ-Ni, WC, W2C, Cr7C3, CrB, and FeNi3 phases. With the decrease in main arc current, the microstructure is gradually refined, and the grain size and Schmidt factor are reduced, which are 12.62 ± 2.6 μm and 0.42, respectively. At the same time, the coating has a strong γ-Ni texture in (111) orientation. The refinement of the coating microstructure and the existence of surface passivation film slow down the electrochemical corrosion in boric acid solution and effectively improve the corrosion resistance of the coating. The increase in microhardness is due to the second phase strengthening mechanism of WC and Cr7C3, and the maximum value can reach 663.5 ± 6.2 HV.

With the increase in the main arc current, the average corrosion depth rate (MDER) of the coating can be reduced to 1.02 ± 0.03 μm/h, which is due to the improvement of the independent repair ability of the passive film, and the microhardness test results are inversely related to MDER.

Therefore, this study establishes a multi-objective parameter optimization design method based on NSGA-II to optimize the thickness of the CeYSZ/Al2O3 DCL-TBCs. Experimental verification of the coating performance was conducted based on the optimization results. Firstly, based on theoretical and numerical models, a quantitative analysis was conducted on the effects of the thickness of each material in the CeYSZ/Al2O3 DCL-TBCs system on thermal insulation and thermal stress. Space parameters were obtained using optimal Latin hypercube sampling, and a radial basis function (RBF) neural network surrogate model was constructed based on the numerical calculation results. Sensitivity analysis was employed to evaluate the impact of the total thickness of the TBCs and the thickness of the Al2O3 ceramic layer on the objective function. Finally, NSGA-II was utilized for optimization. The obtained Pareto optimal solution set was validated, showing that the performance of the CeYSZ 190 μm/Al2O3 120 μm DLC-TBCs satisfied the requirements.

A comprehensive understanding of influence of the sliding parameters on the wear process was understood based on different wear mechanisms. It was found that low sliding speeds resulted in predominantly abrasive wear, while high sliding speed led to mainly fatigue wear with a minor amount of abrasive wear. Interestingly, alterations in applied load and sliding distance did not induce a transformation in the wear mechanism itself; rather, they manifested in variations in the severity or extent of the wear mechanism.
