在工业生产中,有许多金属配件是在磨蚀环境中服役的,对于用来生产这些配件的金属材料,仅依靠其耐腐性和耐磨性这两个参数来选择是很不够的。因为,腐蚀—磨损的复合作用,不同于静态的化学腐蚀,也不同于一般的机械磨料磨损。在前者,它除了受到腐蚀介质的侵蚀外,还要受到固体磨粒的摩擦或者腐蚀介质自身的冲刷,把金属表面上形成的钝化膜
In industrial production, many metal parts are used in abrasive environments. It is not sufficient to rely solely on the two parameters of corrosion resistance and wear resistance of the metal materials used to produce these parts. Because, corrosion - the complex role of wear, unlike static chemical corrosion, but also different from the general wear of mechanical abrasives. In the former, besides being eroded by the corrosive medium, it is also subject to the friction of the solid abrasive particles or the erosion of the corrosive medium itself, and the passivation film formed on the metal surface
