TiC-Fe based cermet coating with high hardness and superior wear resistance together with low price and environmental friendliness was developed. Initially, the TiC-Fe composite particles were prepared by high energy ball milling, spray drying and plasma spheroidization. These cermet powders not only showed high sphericity and dense microstructure but also presented homogeneous distribution of TiC. Then, the TiC-Fe cermet coating was deposited by high velocity air fuel (HVAF). The results indicated that introducing ceramics would increase the deformation degree of the splats and eliminate the layered structure, which effectively enhanced the microhardness and wear resistance of composite coating. Compared with pure metallic coating, the microhardness of cermet coating increased to 887.5 HV_0.3, while the wear rates of cermet coating reduced by 40% and 60% at 10 N and 25 N, respectively. Besides, the TiC-Fe cermet coating showed much less sensitive to the heavy load. The primary wear mechanism of single 316 L coating was a combination of adhesive wear and severe oxidation, while the TiC-Fe cermet coating showed slight abrasive wear combined with oxidation. The excellent wear resistance together with its harmless to human body make the TiC-Fe based composite coating a potential candidate when using at kitchen ware surface.

开发出高硬度、高耐磨、低价、环保的TiC-Fe基金属陶瓷涂层。最初，TiC-Fe 复合颗粒是通过高能球磨、喷雾干燥和等离子体球化制备的。这些金属陶瓷粉末不仅具有高球形度和致密的微观结构，而且还呈现出均匀的 TiC 分布。然后，通过高速空气燃料 (HVAF) 沉积 TiC-Fe 金属陶瓷涂层。结果表明，陶瓷的引入会增加镀层的变形程度，消除层状结构，有效提高复合涂层的显微硬度和耐磨性。与纯金属涂层相比，金属陶瓷涂层的显微硬度提高到 887.5 HV _0.3，而金属陶瓷涂层的磨损率在 10 N 和 25 N 时分别降低了 40% 和 60%。此外，TiC-Fe 金属陶瓷涂层对重载荷的敏感性要低得多。单层 316 L 涂层的主要磨损机制是粘附磨损和严重氧化的结合，而 TiC-Fe 金属陶瓷涂层表现出轻微的磨粒磨损和氧化结合。优异的耐磨性以及对人体无害，使得 TiC-Fe 基复合涂层成为厨具表面使用的潜在候选材料。
