To find out the best design of surface texture for the purpose of wear resistance and friction reduction,three different designs of micro surface texture(circular,elliptical,groove)with 10%and 20%surface texturing are designed and manufactured on cast iron specimens by means of laser surface texturing technique.The friction and wear performance of the textured specimens is tested using a high-speed ring-block friction and wear testing machine and a UMT-2 friction and wear tester under rich oil lubrication in the State Key Laboratory of Tribology at Tsinghua University.
