摘　　要：为解决航空发动机零件在渗氮生产过程中采用脉冲离子氮化工艺而产生的边缘效应等问题,该文在氨气气氛下对38CrMoAl钢进行活性屏离子氮化处理及脉冲离子氮化,并对渗层的组织结构,渗层厚度等进行了分析。试验结果表明相同的工艺参数下活性屏离子氮化处理工艺会以得到相似的渗氮效果,可以替代脉冲离子氮化工艺。Edge effects and other problems will be arised if using pulsed plasma nitriding process in the acro--engine parts production. To solve the above problems, this paper carried out the active screen plasma nilriding and the pulse plasma nitriding on 38CrMoAl steel in ammonium and analyzed the tissue structures and the thickness of the nitriding layers.The experimental results showed that similar nitriding effects can be obtained under the same process parameters, and active screen plasma nitriding process can replace pulsed plasma nitriding process.
