摘要
Ti(CxN1-x)涂层具有硬度大、强度高、耐磨等性能,而目前采用化学气相沉积法在不锈钢表面制备Ti(CxN1-x)多层涂层的报道较少。用高温化学气相沉积法在316L不锈钢表面分别制备了TiN单层涂层和TiC/Ti(CxN1-x)/TiN多层涂层,比较分析了2种涂层的显微形貌、相结构、硬度、界面结合力及耐磨性能。结果表明:TiC/Ti(CxN1-x)/TiN多层涂层结构致密,厚约10μm;TiN单层及TiC/Ti(CxN1-x)/TiN多层涂层均提高了316L不锈钢的硬度、耐磨性;与TiN单层涂层相比,TiC/Ti(CxN1-x)/TiN多层涂层的显微硬度和界面结合力更好,摩擦系数更低,磨损量更小,耐磨减摩性能更好;2种涂层的磨损破坏机制较一致,主要为磨粒磨损和摩擦氧化。
TiN monolayer coating and TiC/Ti(CxN1-x)/TiN multilayer coating were separately prepared on the surface of 316L stainless steel by high temperature chemical vapor deposition. A scanning electron microscope,an X-ray diffractometer,a microhardness meter,a scrach tester,and a rotary friction and wear tester were separately performed to compare the micro-morphology,phase structure,microhardness,interfacial bonding strength, and wear resistance of the two kinds of as-prepared coatings. Results indicated that as-prepared TiC/Ti(CxN1-x)/TiN multilayer coating possessed compact microstructure and was about 10 μm thick. Both TiN monolayer coating and TiC/Ti (CxN1-x)/TiN multilayer coating were able to increase the microhardness and wear resistance of the stainless steel. Particularly,the TiC/Ti(CxN1-x)/TiN multilayer coating exhibited higher microhardness and interfacial bonding strength as well as better wear resistance than the TiC monolayer coating,and it was dominated by abrasive wear and frictional oxidation.
