てしまう問題点がある。(Problems to be Solved by the Invention) However, when an FFI moving part is formed using a conventional metal matrix composite material containing a hard ceramic reinforcement, the hard ceramic reinforcement scrapes away the mating material during sliding.
There is a problem that so-called abrasive wear occurs frequently and shortens the life of the mating material.

との知見に基づいて本願発明を完成しｌζｂのである。(Means and effects for solving the problem) From the above points of view, the present inventors have determined the composition of the metal that serves as the matrix, and the types and amounts of ceramic whiskers, ceramic fibers, and ceramic particles that serve as reinforcing materials. , rIJ, as a result of experiments with various types and amounts of low-melting metals used as lubricants, 3n, pb, Bi, I
Contains at least one metal element selected from n in an amount of 3% to 30% by weight, and the remainder is Δ1. Mg,C
At least IF selected from U! At least one reinforcing material selected from ceramic whiskers, ceramic fibers, and ceramic particles is added to the matrix metal consisting of the above metals, A1 alloy, MO alloy, and Cu alloy in a volume percentage of 5% to 40%. The present invention was completed based on the knowledge that a metal matrix composite material satisfies both a low coefficient of friction and wear resistance.
以下本発明の限定理由を述べる。The reasons for the limitations of the present invention will be described below.

When it exceeds 0%, the matrix metal becomes soft and wear loss increases rapidly. Therefore, the content of the above-mentioned low melting point typhoon is 3% or more3
Set to 0% or less.

れる。Ceramic whiskers, ceramic II, and ceramic particles all have high hardness and are added as reinforcing agents to improve the wear resistance of the matrix metal and to dramatically improve high-temperature strength. However, the addition ratio of reinforcing material to 71-Rix metal is 5% by volume.
If it is less than 1, the effect of improving wear resistance and high-temperature strength will not be sufficient. On the other hand, when the volume fraction exceeds 40%, the amount of matrix metal in the entire composite material decreases, and the bonding strength between the reinforcing material and the matrix metal decreases. It is set at 5-40%.
