Abstract

This study investigated the performance of High-Velocity Oxygen Fuel (HVOF)-sprayed Titanium Carbide (TiC) and TiC + 50C (50%TiC + 50%CoNi) coatings on SS316 steel under three-body abrasion conditions. The microstructural analysis revealed a homogeneous distribution of TiC particles within the TiC coatings, while the TiC + 50C coatings exhibited a more complex microstructure due to the presence of Co-Ni alloy. Mechanical testing demonstrated the superior microhardness of TiC coatings compared to the SS316 substrate, suggesting enhanced wear resistance. Slurry abrasion tests indicated reduced mass loss rates for both TiC and TiC + 50C coatings compared to uncoated SS316 steel, with TiC coatings exhibiting superior resistance to abrasive wear. Post-abrasion examination revealed distinct wear patterns, including abrasive chipping, plowing marks, crater formation, wear traces, and surface ruggedness.

探索耐磨性：SS316 钢上 HVOF 喷涂 TiC 和 CoNi 涂层的三体磨损评估

本研究调查了高速氧气燃料（HVOF）喷涂的碳化钛（TiC）和 TiC + 50C（50%TiC + 50%CoNi）涂层在三体磨损条件下对 SS316 钢的性能。显微结构分析表明，TiC 涂层中的 TiC 颗粒分布均匀，而 TiC + 50C 涂层由于 Co-Ni 合金的存在，显微结构更为复杂。机械测试表明，与 SS316 基体相比，TiC 涂层的显微硬度更高，表明耐磨性更强。泥浆磨损测试表明，与未涂层的 SS316 钢相比，TiC 和 TiC + 50C 涂层的质量损失率均有所降低，其中 TiC 涂层的耐磨损性更优。磨损后的检查显示出明显的磨损模式，包括磨料崩裂、犁痕、凹坑形成、磨损痕迹和表面凹凸不平。
