Wear-resistant lining material and preparation method

Abstract

The invention discloses a wear-resistant lining material and a preparation method. The preparation method includes following process steps: mixing raw material powder with an auxiliary; forming by pressing; sintering; subsequently processing. The wear-resistant lining material is mainly composed of silica, manganese dioxide, molybdenum disulfide, cerium oxide, cobalt oxide, silicon carbide, ZNS-730, chromium, tin, copper, phosphorus, graphite powder, zirconium, nickel, iron and unavoidable impurities. By improving ingredient proportioning and optimizing powder metallurgy process parameters, rare earth elements and strengthening elements are utilized to generate solution strengthening and dispersion strengthening effect. Compared with existing products, the lining material produced by the method is high in wear resistance and strength, low in friction coefficient and widely used for various wheel shafts, connecting rods and air pumps in industrial production.

Description

technical field

[0001] The invention relates to the technical field of powder metallurgy, in particular to a wear-resistant lining material and a preparation method. Background technique

[0002] Powder metallurgy is a process for producing metal or using a mixture of metal powder, metal powder and non-metal powder as a raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics. Therefore, a series of new technologies of powder metallurgy can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays a pivotal role in the development of new materials. Powder metallurgy It has unique chemical composition and mechanical and physical properties, which cannot be obtained by traditional casting methods. The use of powder metallurgy technology c...
