【Abstract】 Chromizing technics had been investigated for several decades. However, chromizing application is limited for the shortcoming of its technics such as high temperature. It is apparent that chromizing technology needs improving on. At the present time, researchers are doing their best to decrease chromizing temperature and develop compound chromizing. This paper reviews chromizing technology, application, and indicates perspective.更多还原
