焼結による鉄系圧粉体の拡散接合(第4報) SUS304圧粉体の焼結拡散接合 Diffusion Bonding of Ferrous Compacts during Sintering(4th Report) Diffusion Bonding of Compacts Composed of SUS304 Based Materials
The diffusion bonding of green compacts composed of austenitic stainless steel during sintering were investigated. In this case, carbon can not be added to promote the diffusion bonding, because it decrease the corrosion resistance of stainless steels. So that, cupper and nickel were chosen to increase the diffusion bonding.<BR>The specimens composed of a SUS304L-Cu inner and a SUS304L outer shows higher bonding strength than those of a SUS304L inner and a SUS304L-Ni outer. However, as too much addi-tion of cupper make the density of sintered compacts lower, it is considered that the most suitable combination is a SUS304L-2.0Cu inner and a SUS304L outer. The joining surfaces are well diffused and many twins can be observed accrossing the joining surfaces.
