The results show that the chill depth is proportional directly to the of laser machine and is affected by the surface coating. 结果表明,激光表面处理时白口深度的大小与激光器工艺参数P/(Dv)~2/1成线性关系,且受表面涂料的影响;
The chill effect is found to depends upon the enthalpy change of the base materials and coating depth. 焓变涂料激冷作用的大小,取决于基料物质比焓变的大小以及涂层厚度等因素。
