Modified tungsten carbide powder, metal material and preparation method and application of modified tungsten carbide powder and metal material

The invention discloses modified tungsten carbide powder, a metal material and a preparation method and application of the modified tungsten carbide powder. The modified tungsten carbide powder is prepared by sequentially treating tungsten carbide powder with calcium lignosulphonate, neodymium sulfate and sodium carbonate and then performing high-temperature calcination. The metal material is prepared from an aluminum ingot and tungsten carbide powder, and the mass ratio of the aluminum ingot to the tungsten carbide powder is preferably (2-6): 1. The tungsten carbide powder is unmodified tungsten carbide powder or the modified tungsten carbide powder disclosed by the invention. The modified tungsten carbide powder can effectively improve the hardness of the aluminum metal material, and meanwhile, the aluminum metal material keeps high ductility. 本发明公开了一种改性碳化钨粉末、金属材料及其制备方法和应用。所述改性碳化钨粉末由碳化钨粉末依次经过如下处理后再经过高温煅烧制备得到：用木质素磺酸钙处理、用硫酸钕和碳酸钠处理。所述金属材料由铝锭和碳化钨粉末制备而成，所述铝锭和所述碳化钨粉末的质量比优选为2～6：1；所述碳化钨粉末为未改性的碳化钨粉末或者本发明所述的改性碳化钨粉末。本
