The texture with different density were produced on H13 steel surface by acoustooptic Q diodepumped YAG laser processing system.The MMW1A computer controlled universal friction and wear tester was used to investigate the friction and wear characteristics of the texture surfaces under different load and rotating speed with grease as a lubricant.The test results show that surface texture can effectively improve the lubrication properties of the friction pairs under the condition of grease lubrication.With the increasing of texture density,the average friction coefficient is decreased firstly and then increased in a certain range,and the average friction coefficient is the minimum when the texture density is 10%,the minimum average friction coefficient is 〖BF〗01〖BFQ〗8 which is reduced by 3223% compared with the untextured specimen.The friction coefficient is decreased with the increasing of the test load,while which is decreased firstly and then increased with the increasing of the rotating speed.
