Extending the life of a material by depositing a hard coating on its surface is an efficient method, and the matrix in the previous study was cemented carbide. However, there is a significant difference in physical properties between the soft AISI 1045 steel and the hard coating, resulting in poor mechanical and tribological property. In this study, we design and prepared CrN/TiAlN multilayer coatings with hardness gradient by arc ion plating to reduce the residual stress inside the coating and enhance the tribological property. The CrN/TiAlN multilayer coatings are composed of CrN layer, CrN/TiAlN alternating layer, and TiAlN layer, in which the coating interfaces are well bonded without obvious defects. The hardness and modulus of CrN/TiAlN multilayer coatings increase with the CrN transition layer thickness, and the coating with 3.53 μm thick CrN layer has the largest hardness of 39.86 GPa, modulus of 386.72 GPa, and binding force of 24.59 N, as well as the smallest residual stress of −449.6 ± 42.3 MPa. After a 10,000 km simulated vehicle driving test, the wear depth of AISI 1045 steel is greater than 70 μm, while the surface of CrN/TiAlN coating has no obvious wear marks. Gradient design reduces the difference in physical parameters between the coating and the substrate, and the thickness increase of the CrN transition layer reduces the influence of the substrate on the coating strength, which together reduces the residual stress of the coating, improves its bonding force, and enhance tribological property. This work provides important prospects for the application of rotating sealing components in vehicles and theoretical references for improving the wear resistance of sealing surfaces.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"512 ","pages":"Article 132405"},"PeriodicalIF":5.3,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characterization techniques, including RHEED, FE-SEM, AFM, Raman spectroscopy, XPS, HR-XRD, PL spectroscopy, and TEM, were used to evaluate MoS₂ layer and GaN films. Results indicate that the temperature of pre-nitridation on 2D MoS₂ buffer layer significantly affects the quality of GaN films. At 750 °C, the partially degraded MoS₂ layer led to rougher surfaces for the epitaxial growth of GaN, which had broader FWHM in HR-XRD, and increased defect-related emissions in PL spectra. Conversely, at 600 °C, the MoS₂ layer remained intact, resulting in smoother surfaces, improved crystallinity, and fewer defect states for the GaN film. TEM analysis confirmed successful van der Waals epitaxy at the lower temperature, while degradation of the MoS₂ layer was evident at higher temperatures.

The (Co,O)-rich should be from the initial LCO grains, and the (La, Y, Zr, O)-rich regions should be from the initial Y-LLZO grains.

In contrast, the multilayer coating containing pure GYYSZ serves as the control group and is designated as “GZ”. The coatings were prepared on the Mo substrate by the large plasma spraying. The coatings' performance was assessed through burner rig tests under high temperatures and significant temperature gradients, with each thermal cycle lasting 25 s. The coating surface temperature reached 2700 K in the tests. The test life of the GZ coating is only 1 cycle.

The effects of bias voltages on the microstructure, surface morphology, mechanical properties, wear resistance and corrosion resistance of the film were studied. The results indicate that the CoCrNiTi MEAFs consist of both FCC and amorphous structures. The crystallinity of the film is positively correlated with the bias voltage, while the roughness is negatively correlated. This can be attributed to the bias voltage enhancing both the bombardment and diffusion capabilities of the particles. Due to the grain boundary strengthening caused by the increase of crystallinity, the film exhibits high hardness (11.30 GPa) and toughness at the bias voltage of −150 V. The combination of the highest hardness, toughness, and wear resistance ensures that the film achieves optimal wear resistance with the lowest wear rate (2.55 × 10<sup>−4</sup> mm<sup>3</sup>N<sup>−1</sup> m<sup>−1</sup>) at a bias voltage of −150 V. As the bias voltage increases from 0 V to −150 V, the corrosion potential rises from −0.905 V to −0.542 V, and the corrosion current density decreases from 3.8 × 10<sup>−5</sup> A/cm<sup>2</sup> to 0.6 × 10<sup>−6</sup> A/cm<sup>2</sup>.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"512 ","pages":"Article 132380"},"PeriodicalIF":5.3,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
