ABSTRACT:
A bonding method using, as bonding agent, brazing filler metal, or composite plating, or a combination of composite plating and ceramic spraying. In the first case, there are provided on the bonding region titanium powder and brazing filler metal alloyable with the titanium and having a lower melting point than titanium. The heating temperature is set higher than the melting point of the brazing filler metal but not so high to melt titanium. In the second case, the bonding region is coated with composite plating. Plating base material is made of metal alloyable with titanium and having a lower melting point than titanium. Titanium powder is diffused into the plating base material. The heating temperature is set higher than the melting point of the plating base material but not so high to melt titanium. In the last case, the bonding region is coated with the above composite plating, and further covered with ceramic spraying. The heating temperature is set in the same manner as the second case.
