Problems solved by technology

At present, the raw material formula and sintering process of powder metallurgy anti-friction materials in my country are still at a backward stage compared with foreign countries. The prepared composite materials have high porosity and low density, and require subsequent hot-pressing densification treatment, and the preparation process is complicated.
Compared with foreign technology, there is still a big gap

Description

technical field [0001] The invention relates to a composite material, in particular to a copper-based powder metallurgy anti-friction material and a preparation method thereof. Background technique [0002] Powder metallurgy is an industrial technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to produce metal materials, composite materials and various types of products. Powder metallurgy has unique chemical composition and mechanical and physical properties, which cannot be obtained by traditional casting methods. The use of powder metallurgy technology can directly make porous, semi-dense or fully dense materials and products, such as oil bearings, gears, cams, guide rods, knives, etc., which is a less cutting process. Compared with traditional melting and casting methods, powder metallurgy has the following characteristics: [0003] (1) Powder metallurgy technology can min...
