METHOD FOR MANUFACTURING MULTILAYER-STRUCTURE METAL BY USING COMPOSITE SURFACE TREATMENT METHOD AND MULTILAYER-STRUCTURE METAL MANUFACTURED THEREBY

摘要

The present invention relates to a multilayer-structure metal manufacturing method using a composite surface treatment method. A multilayer-structure metal manufacturing method using a composite surface treatment method according to the present invention comprises the steps of: treating a surface of a base layer; forming a protective layer on the surface of the surface-treated base layer; and attaching a solid particle to a surface of the protective layer.
