Abstract

To improve the tribological performance of SS410 steel in seawater, TiCrN and CrSiN coatings were deposited using PVD sputtering and thoroughly analyzed. The CrSiN coating, which exhibits higher hardness and better corrosion resistance, achieved a protective efficiency of 83.70%, surpassing the TiCrN coating by 14% according to anodic polarization tests. Friction and wear properties were evaluated with a ball-on-disk tribometer in artificial seawater, following ASTM G77 standards. The CrSiN coating demonstrated lower friction coefficients and wear rates—1.362 × 10⁻⁶ mm³/N-m compared to 2.632 × 10⁻⁶ mm³/N-m for TiCrN at a 4N load—highlighting the positive impact of Si addition. These coatings markedly enhance the tribocorrosion resistance of AISI 410 steel, addressing issues in marine engine components, extending their service life, and ensuring reliable performance in severe marine conditions. SEM analysis of the uncoated SS410 surface revealed pits and deep grooves.

通过 PVD 溅射 TiCrN 和 CrSiN 涂层增强 AISI410 不锈钢在模拟海水环境中的耐磨性和耐腐蚀性

为了提高 SS410 钢在海水中的摩擦学性能，研究人员采用 PVD 溅射沉积了 TiCrN 和 CrSiN 涂层，并对其进行了深入分析。根据阳极极化测试，CrSiN 涂层具有更高的硬度和更好的耐腐蚀性，其保护效率达到 83.70%，比 TiCrN 涂层高出 14%。按照 ASTM G77 标准，在人工海水中使用盘上球摩擦仪对摩擦和磨损性能进行了评估。在 4N 负荷下，CrSiN 涂层的摩擦系数和磨损率为 1.362 × 10-⁶ mm3/N-m，而 TiCrN 为 2.632 × 10-⁶ mm3/N-m。这些涂层显著提高了 AISI 410 钢的耐摩擦腐蚀性能，解决了船用发动机部件的问题，延长了其使用寿命，确保了其在恶劣海洋条件下的可靠性能。对未涂层 SS410 表面的 SEM 分析显示出凹坑和深槽。
