Description
図3に示すプラズマアトマイズ法と回転ディスクプロセスとを融合させた方法により、線幅が0.3mmのチタン線を、プラズマトーチ12により溶解させて造粒を行なった。このとき、回転ディスク8を100krpmで回転させて、平均粒径が20μmのチタン微粒子を製造した。この微粒子の製造は真空化で行なった。
従来の方法により放電表面処理用電極を作製して、得られた電極を用いて実施例1と同様に放電表面処理によりワーク2上に厚みが300μmの放電表面処理被膜1を形成させて、電極の評価を行なった。
平均粒径が20μmのTiN粒子を金属粉末として用いて、更なる窒化物被膜の形成を行なわなかった以外は実施例1と同様にして放電表面処理用電極を作製した。作製した放電表面処理用電極を用いて、実施例1と同様の方法により電極の評価を行なった。その結果、比較例2で得られた放電表面処理用電極の放電処理においては、基板との密着強度が20MPa以下となり、実施例で得られた電極と比べて、その物性が劣るものであることがわかった。これは、セラミックであるTiNが金属であるTiと比較して脆い特性を有することおよび、融点が3000℃程度と高いことから、放電処理時に十分な溶融が進まず、微粒子状態で被膜に取り込まれる割合が高いためと推察される。
