Description
表1には、本発明に係る粉末混合物の組成が「本発明」で示され、また比較混合物の組成が「比較3」で示されている。製造および用途関連の添加物(例えば、硫化物)は、「その他」に含まれる。本発明の範囲内で使用されたまたは使用可能な混合物の組成のいくつかの例が、表2にまとめられている(出発粉末)。
実施形態1(図1)(比較1、比較3、および本発明)において記載した材料を、めっき(Fステライト)および窒化されたX50弁を摩擦パートナーとして使用する試験において比較すると、100時間の試験の後において、窒化された流出弁の全摩耗(図2)は、本発明の材料でめっきされた弁の全摩耗よりも僅かにのみ大きいことが明らかになった。このトライボロジー組合せは、標準的な商用の比較材料の比較1および比較3よりもずっと優れている。
被覆されてないまたは未処理のNimonic80の流出弁を伴うエンジン試験(500時間、高温および低温耐久性)では、実施形態1において記載した弁座材料(比較3および本発明)は、非常に低い全摩耗を示す。弁座リングおよび弁ディスクにおける摩耗は、低すぎて測定不能である。本発明に係る材料(本発明)では、元の加工痕が依然として視認できる。本発明に係る材料は特殊炭化物の使用量が少ないために特に経済的であるため、比較材料「比較3」に対して大きな経済的利点が、同等の技術的性能(測定不能な全摩耗)を伴いつつ得られる。
