アルミナ磁器と鉄・モリブデン合金の焼結接合 Sinter-bonding of Alumina Ceramic onto Iron-Molybdenum Alloy
Joinning ceramic to metal without interlayer was tried using process from emulsifying of suspension to sintering. Alumina-kerosene suspension (0) was mixed with iron oxide-molybdenum-water suspension (W) and (W/O) emulsion was formed. After casting the emulsion, the (W)particles submerged to bottom due to difference in density between (O) and(W). The dried body was sintered in a reducing atmosphere and transformed to double layer consisting of alumina ceramic and iron-molybdenum alloy. At the area between these layers, protrusions of the alloy were locked in the alumina ceramic and this was considered to be a source of joint strength.
