| 摘 要： | 研究了Ti-6Al-4V合金表面网纹型微结构与Si3N4小球对摩时的水润滑摩擦学性能.利用电火花加工技术在Ti-6Al-4V合金表面加工出不同尺寸的网纹结构,运用正交试验设计方法分析了网纹宽度、深度、间宽比和网纹角度对Ti-6Al-4V合金水润滑摩擦学性能的影响.结果表明:具有合适几何参数的网纹结构能够降低摩擦副在水润滑条件下的摩擦系数和磨损量.当网纹角度在45°时,摩擦副的摩擦系数和磨损量能同时降低.网纹宽度对稳态摩擦系数的影响最大,而网纹深度和夹角对摩擦副材料的磨损影响最大. |

| Abstract: | 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 andangle 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. |
