PLATING METHOD ACCOMPANIED BY PRETREATMENT IN ATMOSPHERE AND PRETREATMENT APPARATUS FOR PLATING

摘要

PROBLEM TO BE SOLVED: To provide a constitution for a plating method by which it becomes possible to form a plating film on the surface of a metal by laser irradiation without performing a surface treatment process in advance. SOLUTION: The plating method comprises irradiating the surface of a metal with laser pulse in a near infrared region having a pulse-width of 1-600 picoseconds in a nitrogen atmosphere to form a nitride film on the surface of the metal and thereafter, plating the surface of the metal on which the nitride film is formed, with a metal. By the method, it becomes possible to form a plating film without performing a surface treatment in advance. A pretreatment apparatus used in the method is equipped with a container 10 which is communicated with a nitrogen gas cylinder 5 and accommodates nitrogen gas. COPYRIGHT: (C)2008,JPO&INPIT
