PROBLEM TO BE SOLVED: To improve a joining property with a steel base material at the time of using a sintered hard allay plate having an excellent wear resistance for a liner. SOLUTION: The sintered hard alloy plate of 1-25 mm in thickness, a high chromium cast iron plate and a steel plate are laminated by diffusion joining wherein a thin sheet of copper or nickel is interposed in a boundary between the sintered hard alloy and the high chromium cast iron or copper is arranged in the sintered hard alloy side and nickel is arranged in the high chromium cast iron side. Whereby, the extreme wear resistance is displayed by the sintered hard allay plate in the surface and the wear resistance is still maintained by the high chromium cast iron even in the case that the whole sintered hard alloy plate parts are worn or the sintered hard allay plate is fallen down owing to a use for a long time. Therefore, a rapid damage caused by wear is prevented and the systematic maintenance working by a periodic inspection is allowed.
