Lubricating self-lubricating metal composite material and self-lubricating metal matrix composite material having excellent strength, lubricity and abrasion resistance, and manufacturing method of the metal composite material and metal-based composite material

摘要

PROBLEM TO BE SOLVED: To provide a self-lubricating metal composite material and a self-lubricating metal-based composite material each having, while sustaining the strength of a metal matrix, a solid lubricant particle distribution suitable for improving the lubricating performance and abrasion resistance.SOLUTION: The provided metal composite material and metal-based composite material each comprise solid lubricant particles at a ratio of 1% to 10% with respect to the volume of a metal matrix. The metal composite material is manufactured by a mixed powder method using a centrifugal force in which a molten matrix is flowed into a mixed powder consisting of a matrix metal powder and solid lubricant particles, and the self-lubricating metal-based composite material of the present invention is manufactured by a mixed powder method using a centrifugal force in which a molten matrix is flowed into a mixed powder consisting of a matrix metal powder, hard particles, and solid lubricant particles.
