Abstract

PURPOSE:To easily produce a cylinder of superior abrasion resistance and sliding characteristics by using a core which is coated with a soluble material and a liner material for cylinder on the surface of a cylindrical core material, in casting a cylinder for engines. CONSTITUTION:A lightweight cylinder used for automotive engines, compressors for coolers, etc. is die-cast of an Al alloy. Since the Al alloy is inferior in abrasion resistance, lubricity, etc., a liner which is superior in these characteristics is formed on the inside surface of the cylinder. A water soluble material 2 such as NaCl which firmly solidifies when melt-sprayed and is readily made dissolved with water or the like is melt-sprayed onto the surface of a cylindrical core material 1 of 0.2- 4mm. thickness for use as the core. A cylinder liner material 3 such as metals, ceramics or cermet is melt-sprayed thereon to 0.5-1.5mm. thickness and this is fitted onto a mandrel 5 of a die-casting machine. Molten Al alloy is cast to insert the liner material 3 to the inside surface of the cylinder 4, and the core material 2 is removed easily by dissolving NaCl in water.
