description	The invention relates to a valve tappet which is characterized in that cold-formed special steel Ocr4NiMoV (LJ steel) is selected as a material, the inner cavity of a cold-extrusion formed tappet has high precision and low roughness, the end surface of the tappet is coated with a high wear-resistant material which is cemented carbide or ceramic. The shape of the tappet is formed by cold extrusion, thus greatly reducing working procedures, improving the production efficiency, and reducing the influence factors on the quality of the product simultaneously; and the end surface of the tappet is coated with the high wear-resistant material to increase the wear resistance of the end surface of the tappet, thus prolonging the service life of the product.
