複合筒部材の製造方法。A slurry-like powder alloy material is produced by mixing wear-resistant metal powder with an organic solvent and an organic solvent-soluble resin, the powder alloy material is applied to a metal plate, and the powder alloy material and the metal plate are passed through a roller. The laminate is pressurized to form a laminate of uniform thickness and formed into a cylinder with the wear-resistant metal powder on the inside.The cylindrical laminate is then sintered and the wear-resistant metal powder is coated with the wear-resistant metal powder. 1. A method for manufacturing a composite cylindrical member, which comprises sinter-bonding the composite cylindrical member to a metal plate, and welding the opening of the sinter-bonded cylindrical laminate.
