45钢固体粉末法稀土、硼、铬、铝共渗工艺研究

Technique of co-permeation of solid powder boron and rare earth boron, chromium and aluminum in 45steel

研究了RE_Mg合金对固体粉末法硼、铬、铝共渗层成分、组织和性能的影响 .发现随着RE_Mg合金加入量的增加 ,渗层中Al2 O3的量不断增多 ,当RE_Mg合金加入量为 5 %时 ,渗层中出现连续致密分布的Al2 O3黑区组织 。

The influence of RE Mg alloy on the composition texture,and property of the permeating layer by solid powder co permeation of boron chromium aluminum,havt been studied It is found that the content of the new phase Al 2O 3 increases gradually with the addition of rare earth to the agent.
