【摘要】 通过对铸型涂刷石墨涂料，浇注低碳钢或低碳合金钢的方法，利用石墨涂料在铸造过程中的强烈渗碳作用，从而得到表面耐磨而心部仍具有一定韧性的复合耐磨材料更多还原

【Abstract】 The composite wear resistant materials, which are wear resistant in case and modest tough in core, are obtained through the intense carburizing of graphite coating during casting process by pouring low-carbon steel or low-carbon alloy steel into sand mold coated with graphite coating更多还原
