Description
DLCコーティングの用途は、非常に高い耐荷力が要求される重要な設計における摩耗の問題を解消するための標準的な解決法として、自動車産業では十分に確立されている。
本発明の目的は、上記の問題に対する解決法を提供することである。さらに、本発明の目的は、DLCまたはDLC含有コーティングの劣化を生じることなく、技術水準と比較して向上した摩耗および摩擦の減少が得られる、MoDTCおよびZDDPなどのMoおよび/またはZn含有添加剤を含有する潤滑剤と組合せてDLCまたはDLC含有コーティングを使用することを可能にする、摺動部品用のコーティング系を提供することである。
Moおよび/またはZn含有添加剤を含有する潤滑剤と相互作用するDLCコーティングの欠点を解消するために、本発明者らは、言及した添加剤に対する化学親和性を提供することができ、その結果、技術水準と比較してよりよい摩擦および摩耗挙動を提供する、金属ドーピングによる新たな改質されたDLCコーティングを設計することを目的とした。
したがって、本発明との関連では、水素を含有しかつ20%以下のMe:C比を有するMe含有DLCコーティングを、以下単にa−C:H:Meコーティングと呼び、20%より大きいMe:C比を有するMe含有DLCコーティングを、以下単にMe−C/a−C:Xと呼ぶ。
初めの試験は、高濃度のMoDTCが、a−C:Hタイプおよびa−C:H:CrのDLCコーティングに強く干渉し、これらの種類のコーティングの耐摩耗性に悪影響を与え得ることを示唆した。
コーティング堆積:2.0・10−5mbar以下の範囲の残圧を有する市販のPVD/PACVDシステム(エリコンパルザーズBAI830DLC)で、異なるCr:C比を有するCr−C/a−C:Hコーティングを製造した。コーティングチャンバは、およそ1m3の容積を有し、2つのマグネトロンソースを備える。基板は2回回転および3回回転でコーティングできる。本実施例の場合では2回回転を用いた。
コーティング堆積:コーティングの炭素含有層の堆積のために、テトラメチルシラン(TMS)またはTMSおよびC2H2ガスの混合物を用いた以外は、異なるCr:C比を有するCr−C/a−C:Xコーティング(式中、X=H+Si)を実施例1におけるCr−C/a−C:Hコーティングと同様に作製した。コーティングの製造には、2.0・10−5mbar以下の範囲の残圧を有する市販のPVD/PACVDシステム(エリコンバルザーズBAI830DLC)を用いた。
本発明の好ましい実施形態は、モリブデンおよび/または亜鉛を含有する潤滑剤とともに使用するための摺動部品であって、該部品は、該潤滑剤と少なくとも部分的に接触することが予想されるコーティングを含有し、該コーティングは、(MeaC1−a)1−bXb(式中、0.3≦a≦0.6、0<b≦0.3)として表わされ得る組成物により形成される少なくとも1つのMe−C/a−C:X層を含有し、

bは、Me、CおよびXを元素バランスについて考慮した場合のXの原子割合である、摺動部品。
