Internal combustion engine component and method for producing the same

摘要

An internal combustion engine component is composed of an aluminum alloy containing silicon, and includes a plurality of silicon crystal grains located on a slide surface. The slide surface has a ten point-average roughness RzJIS of about 0.54 μm or more, and a load length ratio Rmr(30) at a cut level of about 30% of the slide surface is about 20% or more.
