The friction and wear properties of mesh pattern grooves on the Ti-6Al-4V surface as sliding against Si3N4 balls in water are investigated.The surface mesh pattern grooves with different sizes are manufactured using electrical discharge machining(EDM) on the surface of Ti-6Al-4V alloy.The influences of width,depth,interval/width ratio andThe project was supported by the Program for Program for New Century Excellent Talents in University(NCET-10-068) and The Research Fund for the Doctoral Program of Higher Education(20093218110026)and Aeronautical Science Foundation of China(2011ZE52054)and Natural Science Foundation of Jiangsu Province(NSFJS)(BK 2010074) and Funding of Jiangsu Innovation Program for Graduate Education(CXZZ11-0197) and Opening Funds of State Key Lab of Mechanical Transmission in Chongqing University(SKLMT-KFKT-201005). angle for mesh pattern grooves on the tribological properties of Ti-6Al-4V alloy in water are analyzed with the orthogonal experiment method.The results show that the mesh pattern grooves with suitable geometric parameters could effectively reduce the friction coefficient and wear rate of tribopairs in water lubrication.When the angle of the mesh pattern groove is 45 degree,the friction coefficient and the wear of the tribopairs all decrease simultaneously.The width of the mesh pattern grooves is the major factor to influence the friction coefficient of tribopairs,while the depth and crosshatch angle of the mesh pattern grooves are the important factors to influence the wear ability of tribopairs.
