Title:

METAL PRODUCT PRODUCING METHOD, METAL PRODUCT, METAL COMPONENT CONNECTING METHOD, AND CONNECTION STRUCTURE

Document Type and Number:

WIPO Patent Application WO/2004/111303

Kind Code:

A1

Abstract:

A product body is formed, and a defect peripheral portion including a defect produced in the treated surface of the product body by the forming is removed to form a recess in the treated surface. By using a molded body molded from a metal powder or a molded electrode fabricated from the heat-treated molded body, pulse discharge is caused between the recess peripheral portion including the recess and the molded electrode in an electrically insulating liquid or in the air. On the material of the molded electrode, deposition is formed by using the discharge energy to gradually form a build-up around the recess.
