摘要
机械能辅助渗铝是将机械能与热能相结合一种新渗铝工艺，可以将渗铝温度降低到560～650℃。本文通过实验对机械能辅助渗铝工艺进行了研究，对主要工艺参数进行了优化，获得了组织致密、渗层厚度≥60μm、以Fe2Al5相为主要组成相的渗铝层，并研究了渗铝钢的抗高温氧化性能及机械性能。
The aluminizing temperature was decreased from 950 - 1050 ℃ to 560 ℃-650 ℃ by a new process of mechanical energy aided aluminizing . This will bring a new way for the manufacture of low - temperature aluminizing steel. The superior parameters of process were tested and a aluminized layer with more dense, thickness more than 60 um and taking Fe2Al5 as main constituent had been abtained . The oxidization resistance at high temperature and mechanical properties of the aluminizing layer on surface of steels had been discussed also.
