The utility model relates to a metal sliding component. The metal sliding member includes a metal base layer, a first surface layer over the metal base layer, and a second surface layer between the first surface layer and the metal base layer. Wherein the first surface layer is made of a material with a low friction coefficient or/and high wear resistance, the material of the second surface layercontains the same elements as the material of the first surface layer, and the elements are selected from any one or more of sulfur, carbon, nitrogen and fluorine. The first surface layer has the characteristics of low friction coefficient and high wear resistance, and the first surface layer is not easy to fall off. 本实用新型涉及一种金属滑动构件。该金属滑动构件含有金属基底层以及位于所述金属基底层之上的第一表面层以及位于第一表面层和金属基底层之间的第二表面层。其中，第一表面层由具有低摩擦系数或/和高耐磨性的材料制成，第二表面层的材料中包含与第一表面层的材料相同的元素，元素选自硫、碳、氮、氟中的任意一种或多种。第一表面层具有低摩擦系数和高耐磨的特性，且第一表面层不易脱落。
