VEHICULAR DECORATIVE COMPONENT HAVING BLACK PLATING FILM AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a vehicular decorative component which has a black-colored appearance and is hardly damaged, and to provide a method for manufacturing the same.SOLUTION: The vehicular decorative component comprises: a resin substrate 4; a base plating layer 2 stacked on the resin substrate 4; and a black plating layer 1 stacked on the base plating layer 2, and has the black plating layer 1 that is formed so as to be an outermost layer. The method for manufacturing the vehicular decorative component comprises: a step of stacking the base plating layer 2 on a surface of the resin substrate 4; a step of stacking the black plating layer 1 formed of a cobalt-chromium based alloy, on the base plating layer 2; a step of subjecting a surface of the black plating layer 1 to acid dipping treatment to form a black film layer 1a; and a step of passivating the black film layer 1a.
