摘要
为了提高16Mn钢的干滑动磨损耐磨性能,以Ni60、钛粉和石墨粉为原料对16Mn钢表面进行感应熔敷处理,制备出以TiC颗粒为增强相的原位自生复合涂层,利用金相、SEM、XRD等技术分析了涂层的显微组织,在室温干滑动磨损试验条件下测试了涂层的耐磨性。结果表明:涂层中TiC颗粒均匀分布于共晶基体上,整个涂层组织均匀、无气孔、无裂纹;涂层与基材形成了良好的冶金结合,涂层具有很高的硬度,在室温干滑动磨损试验条件下具有优异的耐磨性能。
To improve the dry wear resistance of 16Mn steel, a wear resistance TiC reinforced metal matrix composite coating was fabricated on 16Mn steel subatrate by induction cladding using the Ni60, titanium and carbon alloy powders. The microstructure of the composite coating was investigated by OM, SEM, XRD, The results indicate that the induction clad composite coating is free from porous and microcracks and has a homogeneous microstructure consisting of TiC particles uniformly distributed in the eutectic matrix. The induction clad composite coating has high hardness and excellent wear resistance under dry sliding wear test conditions.
