对抗磨蚀金属材料的基础研究表明，在10种常用结构材料的金属中，以钨、钴、铬的抗气蚀性最佳；生产应用研究结果表明，钨系材料中的火焰喷焊WC-M硬面陶瓷材料，铬系材料中的电镀稀土铬硬面材料，钴系材料中的等离子喷焊CoCrWC硬面材料，都是抗磨蚀性能较优，成本较低，并可进入工业应用的水轮机抗磨蚀结构材料。

For the design optimization of erosion and abrasion resisting metallic materials basic study and productively applied research were conducted. Basic study indicates that W, Co and Cr have better erosion and abrasion resisting property than other ones among ten useful constructive metals. Productively applied researche indicates that thermal sprayed WC- M hard faced ceramics in the tungsten parental materials, rare earth plating chromium in the chromium parental materials, and CoCrWC hard faced ceramic in the cobalt parental materials are better erosion and abrasion resisting materials with high performance and low cost.
