Abstract
【解決手段】オーステナイト相のステンレス鋼を母材とし表面硬化層を設けたオーステナイトステンレス鋼の表面構造において、前記表面硬化層が、浸炭層または浸炭窒化層からなる浸炭硬化層を内層とし、窒化層を外層とする2層構造からなることを特徴とするオーステナイトステンレス鋼の表面構造とする。この表面構造は、炭化水素ガスからなる浸炭用ガスまたは炭化水素ガスと共に窒素ガスを含む浸炭窒化ガスの雰囲気内で、オーステナイト相のステンレス鋼を母材とするワークに、陰極電圧を放電状態で印加し400〜500℃でプラズマ浸炭層またはプラズマ浸炭窒化層からなる浸炭硬化層を形成し、その後、窒素ガスを含む雰囲気内で前記ワーク表面に450℃以下でプラズマ窒化層を形成することにより形成できる。
【選択図】なし
Description
また、浸炭硬化層は、浸炭層または浸炭窒化層のいずれであってもよい。
まず、処理室にオーステナイト相のステンレス鋼からなる母材を装入して排気した後、水素、アルゴンなどの希釈用ガスと共に、例えばメタン等の炭化水素ガスの濃度を1〜10%程度に注入し、残りをアルゴン(Ar)等の希釈ガスとして処理室に導入し、かつ3A/cm2程度の直流高電圧を印加して1時間程度保持する。
オーステナイト系ステンレス鋼を溶体化処理した後、最終研削し、表面をオーステナイト組織とし、表面硬化層形成のためのプラズマ処理を次の条件で行なった。
[耐食性試験]
耐食性試験として、実施例および比較例を室温で5%食塩水に浸漬し、発錆までの所要時間を調べ、その結果を表2に示した。
乾燥往復滑り摩擦試験を行なった。すなわち、相手材をSi3Nを主材とするベアリング用セラミックスボールとし、荷重を12Nとして、実施例または比較例を4000回往復した後に生じた摩耗トラックを中心で横切るように表面形状を測定し、摩耗断面積に往復ストロークを乗じた値を摩耗量(mm3)として調べ、結果を図5に示した。
