采用新工艺在40Cr钢表面制备了含TiB_2陶瓷相的覆层材料,覆层平均厚度为100～150um,表层硬度在1800～2500HV之间.磨料磨损试验表明,新工艺提高了材料的表面硬度,改变了磨损状态,有效提高了材料的耐磨性能.研究成果可用于模具及耐磨蚀材料领域.
The new technology was used to prepare the coating material containing TiB 2 ceramic phase on the surface of 40Cr steel with an average thickness of 100-150um and a surface hardness of 1800-2500HV.The abrasive wear tests showed that the new technology improved the surface hardness of the material, Change the wear status, effectively improve the wear resistance of the material.The research results can be used in the field of molds and abrasion-resistant materials.
