Title:
METHOD FOR MANUFACTURING METAL SUBSTRATE HAVING PATTERN FORMED THEREON AND METAL HAVING PATTERN FORMED THEREON MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2018/074711
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a metal substrate with a pattern formed thereon capable of preventing cracking, abrasion and peeling due to an external force as compared to a conventional plating method or a method using mechanical coupling. The method comprises: a pattern forming step of forming a pattern on an upper surface of a metal substrate (100); a pattern layer forming step of forming a pattern layer (200) along the pattern formed on the metal substrate (100); and a heat treatment step of heat-treating the metal substrate (100) which has passed through the pattern layer forming step. A diffusion coefficient of a metal forming the pattern layer (200) is larger than a diffusion coefficient of a metal forming the metal substrate (100).
