摘要: A cylinder for an internal combustion engine and a method treating the inner surface of cylinder, which enables constituting piston-sliding to have high quality plated layer is uniform in thickness smooth at low cost without necessitating grinding work such as honing work. The present invention are characterized that provided with deposited thereon by PR (Periodical Reverse) employing high-speed polarity reversal power source.
