図12は従来技術によるバルブリフタの窒化後にポーラス層を除去した冠面断面のTEM観察写真(30000倍)である。
図13は本発明によるバルブリフタの摺動試験後における冠面表面の顕微鏡写真(8000倍)である。
図14は本発明及び従来技術によるバルブリフタと相手材カムのならし運転前後における表面粗さの変化を示す図である。
図15は本発明によるバルブリフタと相手材カムとの摺動試験前後での表面粗さの変化を示す図である。
前記した本実施例の本発明によるバルブリフタと比較例4の従来技術によるバルブリフタおよびカム部をチル化したチルカムをエンジンに組付け、回転数1000〜4000 rpmでモーターリング試験を行ない、摺動時の摩擦トルクを測定した。図14は、本発明と従来技術によるバルブリフタのならし運転前後でのバルブリフタの冠面及び摺動相手材のカム(カムノーズ部)の表面粗さの変化を示している。本発明によるバルブリフタは、自身の表面粗さの増大を起こすことなく、その磨き機能によりカム側の表面粗さを向上(低減)させることができる。一方、従来技術によるバルブリフタは、ならし運転前後でバルブリフタ自身の表面粗さが大幅に増大する。
