冲蚀是材料的一种表面磨损失效形式，会给流体机械造成严重的损害，通过选材和热处理不能取得明显的防护效果。不过采用表面强化的手段，有希望提高钢铁材料的耐冲蚀性。本研究设计了一系列覆层配料和熔敷工艺，并对其进行了冲蚀试验，得出了有益的结论
Erosion is a form of wear and tear on the surface of the material, which can cause serious damage to the fluid machinery. The obvious protection effect can not be obtained through material selection and heat treatment. However, the use of surface hardening means, there is hope to improve the corrosion resistance of steel materials. This study designed a series of coating ingredients and deposition process, and the erosion test carried out to draw a useful conclusion
