利用试验优化技术设计试验方案，采用激光图形雕刻加工的手段实现齿轮表面仿生非光滑形态，研究非光滑与光滑两种形态齿轮的耐磨损性能。
Using optimum design for experiment scheme, laser graphic texturing was adopted to form bionic non-smooth microstructure on the gear surface to study anti-wear capability of the gears.
激光雕刻仿生非光滑表面耐磨性提高的原因是：晶粒超细化，硬度提高，桩钉效应和仿生效应。
The reason for abrasive wear resistance enhancement of bionics smooth surface made by Laser Carving Technology is grain super-refining strengthening, hardening, effect of dowel pin and bionics.
