渗铬使热变形模具表面强化,是提高其寿命的有效方法之一。 对模具渗铬的工艺很早就知道了,但是由于所采用的装置工作空间不能保证密封,得到的结果不稳定。
Chromizing chromizing the surface of the hot deformation mold, is an effective way to improve its life. Chromizing the mold has been known for a long time, but the results obtained are not stable due to the inability of the working space of the device to be sealed.
