[Object] Provided is a technique capable of reducing the possibility of generation of a Cu—Sb compound in an overlay and the possibility of delamination between layers.

[Solution] A sliding member includes: an overlay including an alloy plating film of Bi and Sb; a lining including an Al alloy; a first intermediate layer including Cu as a main component, and laminated on the lining; and a second intermediate layer including Ag as a main component, and connecting the first intermediate layer and the overlay.

A process of forming a low cost, erosion, oxidation, and wear resistant composite liner or insert that can be installed into a shot chamber in a die casting machine is provided. The process utilizes a self-healing erosive wear resistant coating on a liner of refractory metal to serve as the working surfaces of a shot chamber. The refractory liner is bonded to a low cost material so that the liner can be made extremely thin. Such a composite liner is expected to have an improved service life for die casting of corrosive metals and alloys.
