采用真空实型铸渗法(V-EPC)工艺,成功制备了以高铬钢为基材,WC颗粒为增强颗粒的表层复合材料。结果表明,用含有WC颗粒和高碳铬铁颗粒的预置块制备的不同WC颗粒体积分数的高铬钢基表层复合材料,WC颗粒均匀分布于复合层中,复合层在颗粒熔化、元素扩散互溶、金属液渗入的共同作用下形成由WC、W2C共晶组织,未溶解的高碳铬铁颗粒和各种析出的碳化物组成的组织。 Using vacuum solid infiltration method (V-EPC) process, successfully prepared high chromium steel as the substrate, WC particles as a reinforcing particle surface composites. The results show that the WC particles are uniformly distributed in the composite layer with the high volume fraction of WC particles prepared from the pre-prepared blocks containing WC particles and high-carbon ferrochromium particles. The composite layer melts and the elements diffuse Mutual solubility, the infiltration of molten metal formed by the WC, W2C eutectic, undissolved high-carbon ferrochrome particles and a variety of precipitated carbide composition of the organization.
