摘要
采用金相组织分析、显微硬度测试以及普通辉光离子氮化炉等方法和设备 ,研究经不同方式预处理的氨气对离子氮化速度和氮化层组织的影响。结果表明 ,氨气经预处理后 ,离子氮化的速度和组织均有较明显的改变 。
In this paper,the effect of various pretreatment of ammonia on the nitriding rate and structure of nitriding layer in ion-nitriding has been investigated by means of examination of optical microscope,micro-hardness and general ion-nitriding furnace.The result shows that the pretreatment of ammonia has distinct influence on the nitriding rate and structure.Especially,the best result can be attained by using ammonia which had been filtered and decomposed.
