摘　　要：作为新兴的表面改性技术,表面织构化可以有效减少摩擦,在摩擦表面应用较为广泛。本文介绍了0Cr17Ni7Al表面织构微机械加工技术,研究了相同载荷及转速工况条件下的光滑表面与凹槽织构表面在摩擦过程中的摩擦性能及磨损机理。研究发现,精雕JDGR200T高速加工中心可以加工0.8mm宽度0Cr17Ni7Al表面凹槽织构,且凹槽槽底圆滑平整,光滑表面的摩擦系数高于凹槽织构表面,但二者的磨损量差别不大。Surface textured is a new surface modification technology in recent years,which can effectively reduce friction and has been widely popularized on friction surface.This paper introduces the surface texture micromachining technology of 0Cr17Ni7Al,and studies the friction properties and wear mechanism of smooth surface and groove texture surface under the same load and speed.It is found that JDGR200T precision carving high-speed machining center can process 0.8mm width 0Cr17Ni7Al surface groove texture,and the bottom of the groove is smooth and flat.The friction coefficient of the smooth surface is higher than that of the texture surface,but there is little difference between the two.
