本文研究在不给油状态下长期使用的自润滑轴承材料的有关烧结复合材料。从节省资源和再利用资源的观点出发,该材料用铸铁或铜合金铸件切屑所制成的粉末作为原料,添加作为固体润滑剂的石墨、或在铁基烧结材料中浸渍热可塑性树脂而制成。一、铸铁粉烧结材料的摩擦磨损特性 1.铸铁粉烧结材料 This paper investigates the relevant sintered composites of self-lubricating bearing materials that are not used for a long period of time in the oil-free state. From the viewpoint of resource saving and reuse of resources, the material is made of a powder made of cast iron or a cast-iron alloy chip as a raw material, graphite as a solid lubricant is added, or an iron-based sintered material is impregnated with a thermoplastic resin . First, the friction and wear characteristics of cast iron powder sintered material 1. Cast iron powder sintered material
