摘　　要：采用脉冲电沉积方法在45#钢表面制备Ni-Al N镀层。利用显微硬度计、摩擦磨损试验机及摩擦因数测定仪研究Ni-Al N镀层显微硬度、磨损量及摩擦因数,并利用扫描电镜(SEM)观察Ni-Al N镀层磨损表面形貌。结果表明,当脉冲占空比为50%,Ni-Al N镀层显微硬度达到最大值808HV,磨损率达到最小值0.104%,摩擦因数达到最小值0.33。镀层表面划痕较浅,且黏着磨损现象较轻。The Ni-Al N coating was prepared on the surface of 45#steel by pulse electrodeposition. The microhardness,wear and friction coefficient of Ni-Al N coating were studied by microhardness tester,friction wear testing machine and friction meter. The surface morphology of Ni-Al N coating was observed by using scanning electron microscope（SEM）. The results show that when the pulse duty is 50%,the maximum microhardness,minimum wear loss weight and the minimum friction coefficient of the NiAl N coating reaches 808 HV,0.104%,0.33,respectively. The SEM analysis shows that the worn surface of the Ni-Al N coating obtained at this condition is shallow with less adhesion.
