Description
また本発明の約90〜95℃にて溶融する合金は、Zn0.05〜0.4質量%、Bi43〜55質量%、残部Inからなることを特徴とする可溶栓用合金である。
表1および表2に示した可溶性合金を作り、各合金組成の示差熱分析による加熱曲線を測定して吸熱ピークの開始点、吸熱ピークの最下点、吸熱ピークの終了点をもって、固相温度、ピーク温度、液相温度を測定した。表1および表2に各合金の溶融温度を示す。
表1の中で比較例4および5は、特許文献2および3の可溶栓用合金である。
溶融温度の測定条件は次の通り。
1.示差熱分析の測定
・示差熱分析測定装置 SII製示差走査熱量計
・昇温速度:5deg/min
・試料重量:10 mg
1.) Bi-In-Sn系合金では65℃、およびBi-In-Znでは85℃に設定した恒温室中に可溶栓を入れ、コンプレッサーに接続して、15MPaの圧力を掛ける。
2.) 24時間後に可溶栓を恒温室中から取り出し、コンプレッサーとの接続を解除する。
3.) 24時間放置後に、充填した可溶合金がブランク材から抜け出た長さを測定する。
4.) 表1および表2に耐圧試験を実施した時に伸びた合金の長さを、図2に表1の実施例と比較例の合金組成を65℃の条件で測定した代表的写真を示す。写真の中で、1は実施例8の可溶栓、2は比較例4の可溶栓、3は比較例5の可溶栓の結果である。
1.) 可溶栓をコンプレッサーに接続して、3MPaの圧力を掛ける。
2.) コンプレッサーに接続した可溶栓を水槽中に投入して、水槽の水を加熱する。
3.) 水槽中の可溶栓から一気に空気が抜けた温度を作動温度として測定する。
