Fe5/10%WC/5% MoS2 self-lubricating coating was prepared by laser cladding technology, and then elliptical micro-textures with different arrangement angles (0°, 45°, 90°) were processed on the surface of the coating by laser micro-texture technology. The friction and wear behavior of the micro-texture coating was investigated from the perspectives of friction coefficient, volume wear loss, and wear morphology. The improvement effect of micro-texture on the wear resistance of the coating was discussed, and the synergistic anti-friction mechanism of the self-lubricating coating and surface micro-texture was explored. The results show that the friction coefficient and volume loss of the 0° textured coating are the smallest under the external load of 70 N, and the wear mechanism is characterized by slight abrasive wear. The 45° textured coating exhibits local adhesive traces in addition to a few micro-cutting furrows, suggesting a combination of slight abrasive wear and adhesive wear. The friction coefficient and volume loss of the 90° textured coating are the largest and the volume loss is greater than that of the non-textured coating. The wear mechanism is dominated by fatigue wear, accompanied by slight abrasive wear and adhesive wear. During the friction and wear process, the elliptical micro-pits can promptly capture wear debris, reducing the continuous damage to the coating. Additionally, the solid lubricant (MoS2) stored in the micro-pits can provide continuous lubrication to the friction contact area and effectively decrease the friction coefficient.</div>","PeriodicalId":679,"journal":{"name":"Journal of Thermal Spray Technology","volume":"33 8","pages":"2748 - 2759"},"PeriodicalIF":3.2,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844808","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}

Microstructural and element distribution maps, as well as phase analysis of the produced coating, were determined using field emission scanning electron microscopy, energy-dispersive spectroscopy, and x-ray diffraction.

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.
