POWER-FEEDING ROLL AND METHOD FOR MANUFACTURING POWER-FEEDING ROLL

摘要

PROBLEM TO BE SOLVED: To provide a power-feeding roll made of a stacked body in which a substrate cylinder and an outer circumferential surface layer are uniformly joined along the whole perimeter and length of the overlapped surface, and to provide a method for manufacturing the power-feeding roll. SOLUTION: The power-feeding roll includes the substrate cylinder 20 made from copper or a copper alloy and the outer circumferential surface layer 30 which is formed on the outer circumference of the substrate cylinder 20 and is made from a metal or a metal compound. The substrate cylinder 20 and the outer circumferential surface layer 30 are joined through a diffusion joining layer 40. COPYRIGHT: (C)2010,JPO&INPIT
