Abstract
A sliding member for a compressor includes a base metal, a first layer and a second layer. The base metal is made of an aluminum-based metal. The first layer is formed on or over the base metal and made of a nickel-based plating layer containing at least one material of nitrogen (N), silicon (Si), titanium (Ti), chromium (Cr) and aluminum (Al) as an additive. The second layer is formed on the surface of the first layer and made of a diamond-like carbon layer containing the same additive as the additive contained in the first layer.
