| 摘 要： | 通过超音速火焰喷涂工艺在Cr12模具钢表面上喷涂制备了WC-x Co-3Cr(x=8,10,12,14)涂层,并采用金相显微镜、扫描电镜、显微硬度仪和摩擦磨损试验机表征分析涂层的微观结构、显微硬度、耐磨损性能和耐腐蚀性,考察了不同Co含量对涂层组织和性能的影响。结果表明,Cr12模具钢超音速火焰喷涂后表面的耐磨损性能比喷涂前的基体耐磨损性能有较大的提高;表面硬度在不同程度上都得到提高,界面结合良好,其中WC-10Co-3Cr涂层的组织致密性最好、显微硬度最高、耐磨损及耐腐蚀性能最好。

| Abstract: | WC-xCo -3 Cr( x =8 ,10 ,12 ,14 ) coatings were prepared by HVOF( high velocity oxy -fuel ) process on Cr12 mold steel surface. Using metallographic microscope,scanning electron microscope,microhard-ness tester,and friction and wear testing machine characterization analysis of coating microstructure,microhard-ness and wear resistance and corrosion resistance are investigated under the influence of different Co content on the microstructure and mechanical properties of the coating,the results show that the Cr12 steel surface wear re-sistance is higher than after the supersonic flame spraying spraying of matrix wear resistance of improve the quali-ty;Surface hardness is improved in different extent,combined with good interface,including WC-10Co-3Cr coating best tissue density and microhardness,wear resistance and corrosion resistance of the best. |
