The unsmoothed characteristics of some living beings in soil have wear reduction and wear resistance function . The research benefits the revelation that a tungsten carbide reinforced Cu-base alloy wear-resistant composite coating was produced on mild steel by spark plasma sintering.Under the condition of two bodies abrasive wear ,the coating with the structure that hight hardness and good wear resistance WC particles embedding in tough fine Cu-base alloy matrix resist the abrasion wear and manifest the good wear reduction and wear resistance properties that the unsmoothed bodysurface of some living beings in soil have.

本研究受到某些土壤动物体表非光滑几何特征具有减磨、耐磨特性的启示，应用放电等离子烧结工艺，选取具有优良塑性的Cu基合金作为复合层基体，硬质点WC颗粒作为增强相，在碳钢表面形成WC\ Cu基合金耐磨复合层，在两体静载荷磨粒磨损条件下，高硬度、耐磨WC颗粒镶嵌在高塑性的Cu基合金基体中，共同抵抗磨粒的磨削，表现出某些土壤动物体表非光滑几何特征所具备的优良减磨、耐磨特性。
