セラミックスとアルミニウムの接合におけるアルミニウムによる機械的メタライズ処理の効果

抄録

In joining of four kinds of ceramics, Si₃N₄, SiC, Al₂O₃ and PS-ZrO₂ (partially stabilized), to aluminum with fusible inserts of Al-Mg and Al-Si alloys, mechanical metallizing with aluminum was attemped and its effects were investigated in connection with an insert and joining temperature. As to the metallizing treatment, aluminum was rubbed over the joining surface of ceramics. The metallizing treatment increased bond strength remarkably for Al-Mg alloy insert, but did not for Al-Si insert. The increase in bond strength using Al-Mg alloy insert was due to relief of high thermal stress, which was caused by the metallized aluminum. A large decrease in the joining temperature was not obtained to assure the bond strength higher than the tensile strength of the base aluminum.
