摘要: 海工装备服役过程中关键件长期处于腐蚀-磨损交互作用的复杂环境,致使其表面损伤严重,影响设备运行的安全性和可靠性。对工件表面进行处理形成结合良好的热喷涂涂层是解决这一问题的有效途径。利用等离子增强高速电弧喷涂技术(Plasma-enhanced high-speed arc technology,PE-HAS)成功制备出Fe基涂层,并研究喷涂功率对涂层微观组织、力学性能及耐磨耐腐蚀性能的影响。研究结果表明,涂层的物相组成主要为奥氏体和马氏体。当喷涂功率不足或过大时,涂层的组织结构会变差,从而导致其摩擦学和耐腐蚀性能变差。当喷涂电流优化至500 A时,可以提供优良的组织结构,从而提升涂层的力学性能、摩擦学和耐腐蚀性能。综上,等离子增强高速电弧喷涂过程中控制喷涂功率对丝材熔化很重要,从而影响涂层的组织结构致密性。

Abstract: In the service process of offshore equipment, key components are subjected to a complex environment characterized by corrosion-wear interactions over extended periods. This exposure results in significant surface damage, compromising the safety and reliability of equipment operation. Treating the surface of the workpiece to achieve a robust thermal spray coating is an effective solution to this issue. In this study, iron-based coatings were successfully prepared using plasma-enhanced high-speed arc technology (PE-HAS). The impact of spraying power on the microstructure, mechanical properties, and wear and corrosion resistance of the coatings was thoroughly investigated. The results indicate that the primary physical phase composition of the coating consists of austenite and martensite. When the spraying power is either insufficient or excessive, the structure of the coating deteriorates, leading to a decline in its tribological and corrosion resistance properties. Optimizing the spraying current to 500 A results in an excellent microstructural configuration, thereby enhancing the mechanical properties, tribological performance, and corrosion resistance of the coating. In conclusion, controlling the spray power during PE-HAS is crucial for wire melting, which significantly influences the densification of the coating's microstructure.

Key words: PE-HAS, spraying power, organizational structure, mechanical properties, tribological properties, corrosion resistance
