Abstract
PURPOSE: A high melting point sintered metal member is bonded with a general metal member using a bonding agent consisting of silver and a ferrous metal, thereby to provide extremely high bond strength heretofore unobtainable.
CONSTITUTION: A high melting point sintered metal body such as W sintered body 2 is bonded with a general metal such as steel plate. The steel surface 1 is coated with powder of ferrous metal such as Co 3, on which is placed the sintered W body 2. Both metals are heated in an H2 flow and bonded together. The bonding strength is represented by impact value, where if 100 is to indicate the value of conventional silver solder method, the inventive method indicates a value of 200 to 300. Among ferrous metals such as F, Ni and Co, Co metal provides the most superior bonding strength. These sintered composite materials are effectively used as discharge process electrodes or electrical contacts without causing local discharge.
