通过改变激光刻蚀微坑面积占有率Sp及微坑分布角度θ等参数,测得摩擦副运行过程中缸套-活塞环间摩擦系数及缸套下试块磨损量,研究激光刻蚀工艺对缸套-活塞环摩擦副摩擦磨损性能的影响.得出在其他参数不变,θ为30°时,摩擦副间温度及摩擦系数最低,θ为45°时,磨损量最小;深径比为0.1、θ为30°时,Sp为35%,摩擦磨损特性最佳.将激光刻蚀缸套与机械珩磨摩擦磨损特性进行比较,激光微坑刻蚀得到了更低的摩擦系数和更小的磨损量.%To study the effect of laser honing on friction and wear properties, the friction coefficient between cylinder liner testing block and piston ring as well as the wear of bottom cylinder liner testing block were measured by varying area density of micro-pits Sp and micro-pits distribution angle θ. Results show that temperature and friction coefficient between the friction pairs reach their minimum values at θ= 30°, and the wear gives its lowest value at θ= 45°. Best friction and wear properties achieves ate = 0.1, θ = 30°, Sp = 35％. Compared with the mechanical honing, the laser honing gives the lower friction coefficient and less wear.
