Description
C(カーボン)融点は3550℃
B(ボロン)融点は2092℃
Mo(モリブデン)融点は2623℃
3wt%C−Mo(共晶反応配合)の融点は2205℃
3wt%B−Mo(共晶反応配合)の融点は2175℃
本発明の一態様の3wt%C−3wt%B−残Moの融点は略2000℃である。
C、BおよびMoの粉末を3wt%C−3wt%B−残Moの共晶反応配合になるように、配合混合し、下記条件でディスク状焼結金属部品とした。この焼結部品27を図2Bに示すように下エンドハットのディスク状部に載せ陰極フィラメントと接触した状態で高周波加熱した。加熱温度をBの融点である2092℃よりも低い2050℃に制御したところ各元素が蒸発することなく融解しろう付けすることができた。
C粉末粒度:4〜5μm
B粉末粒度:4〜5μm
Mo粉末粒度:3〜6μm
焼結温度:1200℃
C,BおよびMoの下記粒度の粉末を1wt%C−1wt%B−残Moの共晶反応配合になるように、配合混合し、バインダーでペースト状にする。図2Bに示すように上エンドハットのボス23a部分にディスペンサーによってペースト状ろう材26を塗布して乾燥させる。これを高周波加熱で2050℃で溶解した結果、元素の蒸発なく、ろう付けすることができた。
C(1wt%)、粉末粒度:4〜5μm
B(1wt%)、粉末粒度:4〜5μm
Mo(残り)、粉末粒度:3〜6μm
実施例2において、C,BおよびMoの混合比を下記のように変えて配合混合し、バインダーでペースト状にする。図2Bに示すように上エンドハットのボス23a部分にディスペンサーによってペースト状ろう材26を塗布して乾燥させる。これを高周波加熱で2050℃で溶解した結果、元素の蒸発なく、ろう付けすることができた。
C(2wt%)、粉末粒度:4〜5μm
B(2wt%)、粉末粒度:4〜5μm
Mo(残り)、粉末粒度:3〜6μm
図7は高周波融解装置を用いて、C、B、Moの各組成比率を変えた実施例1〜13および比較例1〜6の融解温度を示した表である。各元素の粒径は実施例1と同じものを使用した。高周波融解装置は15kW型で、電磁コイルに高周波電力を供給する。コイル内側に、図2に示す陰極構体が複数本、挿入配置できる構造である。上エンドハットのボス23aや下エンドハット24にペーストや焼結ディスクとしたろう材源試料を電磁コイルで加熱融解する。本実施例および比較例は、すでに融解温度がわかっている基準試料とともに同時加熱して、この基準試料の融解状態と照合し試料の融解温度を計測した。測定温度は約20℃のステップで得られる。したがって測定算定温度はほぼ±10℃の誤差がある。
