一、前言关于不锈钢在酸性介质中、土壤中、大气中以及在海水中的腐蚀问题,已有大量研究和报导,但关于在高温碱性介质中的腐蚀问题,则研讨得不多。原因之一是进行高温介质中的腐蚀研究存在着一定的困难。模似试验时须解决系统的安全、防蚀、防爆、防燃以及密封等一系列问题,对此,我们作 I. INTRODUCTION There has been a great deal of research and reports on the corrosion of stainless steel in acid medium, soil, atmosphere and seawater. However, there is not much research on the corrosion of stainless steel in high temperature alkaline medium. One of the reasons is that there is some difficulty in conducting corrosion studies in high temperature media. To simulate the test must be to solve the system safety, corrosion, explosion, fire and seal a series of problems, for which we make
