And with constant working current, the lower scanning speed, the deeper harden layer depth and the higher hardness. 工作电流不变,扫描速度越低,硬化层深度越深、硬度越高。
The results show that there is a harden layer on the surface of parts rolled, which increases with the increment of rolling depth; 结果表明:经滚压后试件表面存在一定深度的硬化层,且随滚压量的增大而增加;
