Abstract
An inside surface of an internal combustion engine liner is treated to have a surface roughness Ra smaller than 0.06 μm, and then receives a DLC coating. A method of producing the internal combustion engine liner includes: forming the liner from a metal material, polishing an inside surface of the liner to obtain a polished inside surface of roughness Ra smaller than 0.06 μm, and applying the DLC coating to the polished inside surface.
