摘　　要：采用铸造烧结方法制备了表面复合材料挺杆,介绍了制备该种挺杆的工艺方法及成分设计。结果表明,该挺杆的复合层和母体合金属冶金结合,具有较高结合强度,在铸造烧结过程中合成了VC颗粒,挺杆的铸态硬度达到了60 HRC以上。A type of surface composite tappet was manufactured by cast-sintering, the process and component design of the tappet were introduced. The results show that the composite layer of the surface composite tappet is metallurgy combined with the parent metal, which has high bonding strength; VC particles were synthesized in the cast-sintering, the as-cast hardness of the tappet reaches above 60 HRC.
