摘要： The invention provides a coating film having excellent adhesion, even without a chemical conversion film treatment being carried out as an undercoat treatment, and a metal automotive part having the coating film. A powder is deposited by powder-coating onto the surface of a metal automotive part that has been quenched after forging, and tempering of the metal automotive part and bake-hardening of the deposited powder are carried out simultaneously, thereby forming a skin film on the surface of the metal automotive part. The surface of the metal automotive part before the powder is powder-coated thereon is a work-hardened basis material surface that has been not subjected to a chemical conversion filming treatment.

摘要： For butt-welding, which includes bringing joining end surfaces (50 and 51) of a cup member (12a) and a shaft member (13a) into abutment against each other and radiating a high energy intensity beam from a radially outer side, the shaft member (13a) has a recess (52 or 53) on a radially inner side of the joining end surface (51) to obtain a welded portion (49) having a closed hollow cavity on a radially inner side after butt-welding. The joining end surface (50) (protruding surface (50a)) of the cup member (12a) protrudes toward a radially inner side with respect to an inner diameter (E) of the joining end surface (51) of the shaft member (13a). With this, a welded portion (74) of an outer joint member (11) of a constant velocity universal joint (10), which is manufactured by joining the cup member (12a) and the shaft member (13a), can be improved in strength and quality.
