The invention discloses a method for improving friction reduction and wear resistance of a base body, and belongs to the technical field of friction and wear. According to the method, alloy powder is cladded on the surface of a base body to form a cladding layer, then the cladding layer is subjected to texturing and sulfurizing treatment in sequence, and a textured ion sulfurizing cladding layer with antifriction and wear-resisting properties is formed on the surface of the base body, so that the antifriction and wear-resisting properties of the base body are improved, the use efficiency of the base body is improved, and the service life of the base body is prolonged. 本发明公开了一种提高基体减摩耐磨性能的方法，属于摩擦磨损技术领域。本发明的方法是先将合金粉末熔覆在基体表面形成熔覆层，之后对熔覆层依次进行织构和渗硫处理，在基体表面形成具有减摩耐磨性能的织构离子渗硫熔覆层，以提高基体的减摩耐磨性能，增加基体使用效率和使用寿命。
