Abstract

See full text

A metal matrix self-lubricating composite and a manufacturing method therefor. The metal matrix self-lubricating composite comprises a metal matrix and a mixture layer compounded on a surface of the metal matrix, the mixed layer comprising a copper alloy and a self-lubricating material. The method for manufacturing the metal matrix self-lubricating composite comprises the following steps: a) sintering copper alloy powder on a surface of a metal matrix to form a copper alloy layer on the surface of the metal matrix; b) blade-coating or dip-coating a lubricating material on a surface of the copper alloy layer, and performing vacuumization to obtain a metal plate, and drying the metal plate; c) repeating step b) for multiple times; and d) sintering the metal plate obtained in step c) to obtain the metal matrix self-lubricating composite. In the present invention, a vacuumization mode is used and vacuumization operations are repeated, so that a dense mixture layer on which a self-lubricating material is dispersed on a copper alloy is formed, and the metal matrix self-lubricating composite has good lubricity and abrasion resistance.
