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.
