摘要：

The surface texture was etched at the dead point, middle point and whole position on the surface of cylinder liner specimens by electrical discharge machining (EDM). The solid lubrication MoS2 was filled with the micro dimples by ball milling. The influence of the micro dimple distribution position on the tribological characteristics of the cylinder liner was studied by using a contraposition reciprocating test rig. The wear morphology was tested and analyzed by SEM and EDS. The results show that the cylinder liner with a composite lubrication structure can reduce the friction coefficient; however, not all the wear and anti-scuffing properties can be improved. Only the mico dimples on the dead point of the cylinder liner with the composite lubrication structure shows the good friction reduction, wear resistance and anti-scuffing properties, compared with the untreated cylinder liner. The friction coefficient and the wear loss of the piston ring decrease 4.97%-6.26% and 58.3%, respectively. The scuffing time is prolonged about 10 times. With sliding, MoS2 in the micro dimplesgradually shifts to the surface of the cylinder liner, thus improving the lubrication performance of the dead point and protecting the friction interface. © 2017, Editorial Office of CHINA SURFACE ENGINEERING.
