综述了材料内在因素和环境因素变化对冲蚀的影响 ,韧性材料的耐冲蚀性能优于脆性材料 ,脆性材料仅在10 0 冲蚀角以下才表现出较好的耐冲蚀性 ;冲蚀下的脆性材料和塑性材料的区分不仅与材料的韧脆性有关 ,还与冲击粒子的动能有关。当粒子质量发生变化时 ,材料的冲蚀机理随之变化 ;影响材料耐冲蚀磨损的重要内在因素是弹性模量而不是硬度 ;各种冲蚀机理都有一定的适应性和局限性
The influence of material internal factors and environmental factors on erosion is summarized. The erosion resistance of ductile materials is superior to that of brittle materials. The brittle materials show better corrosion resistance only under the erosion angle of 10 0. The distinction between brittle and plastic materials is not only related to the ductile and brittleness of the material but also to the kinetic energy of the impacting particles. When the particle quality changes, the erosion mechanism of the material changes accordingly. The important intrinsic factor that affects the erosion resistance of the material is the elastic modulus rather than the hardness. Various erosion mechanisms have some adaptability and limitations
