いう問題点があった。However, although the conventional AI-Si alloy member in which hard alumina particles are uniformly dispersed in the base material has excellent wear resistance and a low coefficient of thermal expansion, the hard alumina particles easily fall off from the base material. Therefore, there was a problem in that the hard particles that fell off abraded the mating member on which it slid, increasing the ability to attack the mating member.

They found that if they were allowed to grow, it would be possible to prevent them from falling off the substrate.
