However, the generation of toxic hexavalent Cr<sup>6+</sup> ions during the plating process poses significant environmental and health hazards, prompting the need for sustainable alternatives. In this context, thermal spray technologies, particularly the high-velocity air-fuel (HVAF) spray, have gained attention as a viable substitute to EHC, offering dense, low porosity coatings with minimal in-flight oxidation and excellent mechanical performance. The study focuses on depositing four feedstock powders of NiCr, SS316L, NiCrBSiFeC, and Tribaloy-400 on Ni-Cr-Mo alloy steel to produce a 1-mm-thick coating employing the HVAF technique. The coatings were evaluated through ball-on-disc sliding wear tests under varied loads, followed by detailed FE-SEM, XRD, and EDAX analysis. Results revealed that the Tribaloy-400 coating exhibited superior wear resistance, with a wear rate of 3.06338E-6 mm<sup>3</sup>/N · m, outperforming EHC plating (4.19325E-6 mm<sup>3</sup>/N · m) by 1.5 times under accelerated loading conditions. The enhancement is attributed to the presence of hard intermetallic lave phases (Co<sub>x</sub>Mo<sub>y</sub> and Co<sub>x</sub>Mo<sub>y</sub>Si), which reinforce the metal-matrix composite coating, and significantly improve the sliding wear resistance. The findings establish HVAF sprayed Tribaloy-400 as a sustainable alternative to EHC plating for the refurbishment of industrial shafts operating under demanding conditions.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"512 ","pages":"Article 132410"},"PeriodicalIF":5.3,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144338370","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}

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.
