Abstract

　コバルト基合金をプラズマ粉体肉盛り溶接した弁装置の信頼性を向上する。 　弁棒１との摺動面を有する軸受けを備える弁装置であって、弁棒１との摺動面に耐熱コバルト基合金からなるプラズマ粉体肉盛りによる溶接層１２が形成され、当該溶接層１２は、軸受けの表面に形成された、希釈率が５～２５％の第１の溶接層１２ａと、第１の溶接層１２ａの上に形成された、希釈率が第１の溶接層１２ａの希釈率の５０％以下である第２の溶接層１２ｂとを備える。希釈率とは、母材への溶接金属の溶け込み量を示すパラメータであり、溶接した金属の全量をＡ、母材へ溶け込んでいる溶接金属の量をＢとすると、Ｂ／Ａ×１００（％）で求められる値をいう。
