HIGH-ADHESION COATING METHOD TO METAL-ALLOY MOLDED OBJECT AND METAL-ALLOY MOLDED OBJECT SUBJECTED TO HIGH-ADHESION COATING BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a high-adhesion coating method to an alloy molded object of a magnesium metal etc., and the metal-alloy molded object subjected to high adhesion coating by the method.;SOLUTION: The high-adhesion coating method to the alloy molded object of a magnesium metal etc., comprises entirely or partly spraying a flame including a modifier combination part such as silane atoms, to the surface of the alloy molded object of the magnesium metal etc., by using a known surface modification device to perform surface modification in such a manner that the surface of the metal-alloy molded object attains ≥73 dyn/cm in wetting index, then performing coating finish of a coating layer to serve as a direct design layer with one-coat finish without applying a primer. The metal-alloy molded object is subjected to the high-adhesion coating by the method described above.;COPYRIGHT: (C)2007,JPO&INPIT
