| 摘 要： | 以45钢为基材,用真空钎焊工艺在其表面制备WC/CuMnNi涂层,通过金相显微分析、扫描电镜观察、HRB硬度测量、电子探针分析、X-射线衍射分析、拉伸试验和耐磨试验,初步研究了涂层材料的组织特点、结合强度、耐磨性。试验结果表明:涂层材料组织分布均匀;涂层/基材的结合机制为冶金结合,有较高的结合强度;涂层的磨损量小于840 ℃淬火+180 ℃回火的45钢,有较高的耐磨性。

| Abstract: | The microstructurebonding strengthwear resistance and hardness values of the WC/CuMnNi coating prepared on the surface of 45 steel by brazing have been investigated in this work with the aid of microscope SEM HRB-hardness determiningEPMA and X-ray diffraction.The experimental results show that the microstructure of the composite coating is homogeneous,and an intermetallic compound exists at the interface between the substrate and the coating,leading to a higher bonding strength;the wear resistance of the composite coating is superior to that of the 45 steel quenched from 840 ℃ and tempered at 180 ℃. |
