Joining structures, electrical contacts, and their manufacturing means

摘要

A joining structure includes plural members and an adhered and deposited layer formed by depositing powder containing metal over the plurality of members. The plural members are joined via coupling with alloying by thermal and mechanical activation between the plural members and the adhered and deposited layer. A substrate is made of a metal of high electrical conductivity. A member to be joined is formed in a cup shape and made of metal of high electrical conductivity. The adhered and deposited layer is a contact layer including fire-resistant metal or compound and metal of high electrical conductivity. One surface of the substrate and a cup-shaped opened end of the member to be joined are joined with the alloying by thermal and mechanical activation.
