Three kinds pit array on the surface of cylinder liner were prepared by using laser device, the diameter were 250 m, 350 m and 400 m respectively. Then, the textured surface was nitriding treated by using nitriding salt bath device. The friction coefficient of the piston ring and the three kinds of surface composite modification cylinder liner was detected by computer controlled friction and wear testing machine. The friction and wear characteristics of cylinder liner piston ring were discussed under different contact pressure and rotational speed. The result showed that the friction and wear properties of cylinder liner - piston ring can be enhanced through the lubrication state improved of the surface texture. The friction coefficient of the composite treated sample was decreased and the fluctuation is small. At te same time, the texture was not destroyed. The friction and wear properties of the samples with different diameters texture were affected by the change of the friction surface and the rotating speed. The wear resistance of the cylinder with the diameter of 400 m is the best.
