耐磨蚀性 meaning in English

resistance to abrasion

So cr30mo has good corrosion - abrasion resistance in phosphoric acid slurry . based on the analyses of microstructure , mechanical properties , corrosion - abrasion resistances and fracture of cast ferritic stainless steel cr30mo with various carbon content , it can be affirmed that high carbon is advantage to increase steel hardness , but disadvantage to suppress brittleness and increase corrosion - abrasion resistance
对不同含碳量的铁素体不锈钢cr30mo的组织结构、力学性能、磨蚀性能和断口形貌的分析后认为，碳含量增大，对钢的硬度提高有利，但对钢的韧性、耐磨蚀性很不利。
