几年来,我所在党的英明领导和有关人员的努力下,在化学热处理方面获得了一些成就,兹特其择要汇报如下:渗铝工艺的研究内燃机气门等零件长期在450～700℃的高温下工作,而且承受冲击负荷及磨损,工厂常采用Х9С2、ЭН107等高合金耐热钢制造。为了节约我国较为稀缺的铬元素,我们试图用45、 40 X等钢种渗铝来代替它们。渗铝的方法很多,考虑到工厂生产条件,我们仅对固体渗铝和浸铝后扩散退火渗铝两种进行了一些研 In recent years, my party’s wise leadership and the efforts of personnel involved in the chemical heat treatment has made some achievements, especially its choice to be reported as follows: Aluminized process of internal combustion engine valves and other parts at 450 ~ 700 ℃ long-term high temperature Under the work, but also bear the impact of load and wear, the factory often used Х9С2, ЭН107 other high-alloy heat-resistant steel. In order to save China’s more scarce chromium, we tried to use 45, 40 X and other aluminum aluminizing instead of them. There are many ways to aluminize, taking into account the factory production conditions, we only aluminized and aluminized solid solution after the diffusion annealing aluminized two research
