Document Type and Number:
WIPO Patent Application WO/2015/159371
Kind Code:
A1
Abstract:
[Problem] To form, on a surface of a metallic material, a coating film which can prevent the surface of a metallic material from being discolored by corrosion due to any heat treatment during production or even due to outdoor use over a long period, and which has excellent wire bonding properties. [Solution] A hexamethyldisiloxane compound is sprayed together with nitrogen gas serving as a carrier gas under atmospheric pressure in a nitrogen plasma gas to convert the hexamethyldisiloxane compound to radicals, thereby polymerizing the compound. Thus, a polysiloxane film which has a thickness of 4-14 nm and which is constituted of a polysiloxane, the main chain of which is -(Si-O-Si)n-, is formed on a surface of a metallic material.
