一、前言在防止机车柴油机穴蚀损伤的措施中,除了用防蚀剂对周围介质处理之外,在很大程度上有赖于表面处理材料的恰当使用。近年来,从节省资源和节能的角度出发,对侧重于耐蚀性、耐腐性的金属表面处理技术和采用此技术作防蚀措施的省力化有了新的评价,与此同时,也要求有一种能简便而正确地评价涂覆材料耐穴蚀损伤性和耐腐蚀、点蚀的检测方法或试验方法。
I. Preface In measures to prevent cavitation damage to locomotive diesel engines, in addition to treating the surrounding medium with anticorrosion agents, it depends to a large extent on the proper use of surface treatment materials. In recent years, from the perspective of saving resources and saving energy, there has been a new evaluation of the metal surface treatment technology focusing on corrosion resistance and corrosion resistance and the labor-saving effect of using this technology as an anti-corrosion measure, and at the same time, There is a simple and correct evaluation of coating material resistance to cavitation damage and corrosion, pitting corrosion detection methods or test methods.
