Abstract
Description
・低い接触抵抗
・優れた電気電導度
・優れたばね特性
・高い疲労強度
・高い耐腐食性
・厚さが3mmより薄く、隣接する少なくとも一方の面が、少なくとも10重量%のクロムを含有する基体合金より成る金属ストリップを備える工程。
・金属ストリップの少なくとも一方の面の基体合金の酸化物層を除去する工程。
・金属ストリップの前記面にニッケル、ルテニウム、コバルト、パラジウムまたはこれらの合金である表面層をコーティングする工程。
・炭素および/または窒素を含むガスを用い、前記表面層を介して基体合金の表面硬化を行い、これにより表面層を介して炭素原子および/または窒素原子を拡散し、炭素原子および/または窒素原子を表面層に隣接する基体合金に溶解し、圧縮応力が表面層に隣接する基体合金に生じる工程であって、表面硬化を炭化物および/または窒化物が形成する温度より低い温度で実施する工程。
厚さ70μm(=0.07mm)のAISI301ステンレス鋼の冷間圧延シートの片方の面を厚さ100nm(=0.1μm)のニッケル層により被覆した。このシートを60%アンモニア中で420℃、17時間窒化した。この処理の後、シートの窒化した面の体積膨張に起因し、シートは湾曲した。このことは、シートが湾曲を避けるのに十分な厚さであれば、窒化により内部圧縮応力を形成することを示している。
