摘　　要：用固体粉末法研究了4Cr10Si2Mo钢进行Al-Ti-Ce共渗的工艺过程。用硬度计测定了渗层的硬度值,并得到了渗层到基体的硬度变化曲线。结果表明,加入稀土元素Ce可明显提高渗速,在相同条件下加入Ce的渗层厚度,明显比不加的要厚,加入Ce的渗层平均硬度提高。In this paper,solid powder of the 4Cr10Si2Mo steel Al-Ti-Ce Penetrating process.Hardness was measured with a hardness of layer and layer to get the hardness of the matrix curve.The results showed that adding rare earth element Ce can improve the infiltration rate,under the same conditions by adding Ce-layer thickness was significantly thicker than that without the added Ce-layer average hardness.

关 键 词：模具钢 Al-Ti-Ce共渗 固体粉末法 硬度变化曲线
