In transient liquid phase bonding, activated diffusion brazing method, boron powder of which purity is 99 %, thickness is less than 100 μm, and melting point is higher than that of matrix is used as an insert metal. Adhesion between matrix and insert metal is obtained by heating at 1,100-1,300 deg.C for 6 hrs., in nonoxidative atomsphere, without melting insert boron powder. The above bonding process is simple and reduces adhesion time.
