Abstract The performance of iron boride coatings on carbon steel produced through thermal diffusion was investigated under tribo-corrosion conditions and compared with bare CS and 316L stainless steel. The tribological experiments involved reciprocating tests under both dry sliding and tribocorrosion conditions with a ball-on-flat geometry. The coatings demonstrated enhanced wear resistance primarily due to higher hardness and chemical inertness of the iron boride protective layer, multi-layered structure providing reduced crack propagation and due to the presence of BN-based layer promoting the decrease in the friction coefficient (COF) by approximately 20%–40%, compared to the steel substrate. The microstructure and surface morphology of the worn surfaces were evaluated, which allowed better understanding the tribo-corrosion mechanisms in tested samples.

通过渗硼和氮化硼涂层增强碳钢的摩擦腐蚀性能

摘要 研究了在摩擦腐蚀条件下通过热扩散制备的碳钢上硼化铁涂层的性能，并与裸 CS 和 316L 不锈钢进行了比较。摩擦学实验包括在干滑动和摩擦腐蚀条件下使用球对平面几何形状的往复测试。涂层表现出增强的耐磨性，主要是由于硼化铁保护层具有更高的硬度和化学惰性，多层结构提供了减少的裂纹扩展，并且由于 BN 基层的存在促进了摩擦系数 (COF) 的降低约 20%–40%，与钢基材相比。评估磨损表面的微观结构和表面形貌，
