Electric heating treatment method, electric heating treatment apparatus, and electrode for electric heating treatment apparatus

摘要

Quality localized surface treatment such as remelting a surface portion of a work by electric heating can be achieved easily by supplying electric current between an energization electrode (1) and the work (10) while holding the distal end portion of the energization electrode (1) nearly in close contact with the surface portion (10a). Localized heating can be successfully accomplished by electric heating based on the heat generated from the self resistance of the energization electrode (1) itself and the heat generated from the contact resistance at the interface between the distal end portion of the energization electrode and the surface portion (10a).
