There is not standard about the available hardened depthof laser quenching gears, which is disadvantage to its application.
齿轮激光淬火有效硬化层深的取值到目前为止没有统一的标准,这对该项技术的推广应用十分不利。

Based on that hardened case depth can be increased by delay in air after forging, the technique of delay quenching after forging is proposed in this paper.
基于锻后预冷淬火可提高工件的淬硬层深度,本文提出锻后余热预冷淬火工艺。
