VACUUM VALVE CONTACT AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To easily form an alloy layer including a conductive component and an arc-resistant component having a fine structure on a contact surface of a contact.

SOLUTION: A vacuum valve contact for use in a vacuum valve having a pair of contacts which can be freely brought into contact with and separated from each other comprises a conductive component layer 20 and an alloy layer 22 which serves as the contact surface formed on the surface of the conductive component layer 20. The alloy layer 22 is formed by disposing an arc-resistant layer 21 on the conductive component layer 20 and fusing the arc-resistant component 21 and a predetermined volume of the conductive component layer 20 on the arc-resistant layer 21 side with energy irradiation to mix the conductive component layer with the arc-resistant component layer. In addition, particles 23b of the arc-resistant component are made fine by the energy irradiation.
