Description
本発明のコーティングを、Tribaly T−400プラズマ溶射コーティングと比較して、試験した。このTribaly T−400プラズマ溶射コーティングは、特定用途においてクロムめっきに代替する方法として現在用いられている。試験では、アクチュエータのボア部を有する試験用ハウジングをコーティングし、油圧アクチュエータの寿命を推定するように、ボア部内のピストンを十分な回数往復させた。この場合、アクチュエータのピストンヘッドを、炭化タングステン−コバルトコーティングを用いたHVOF(高速酸素燃料)でコーティングした。アクチュエータのボア部の母材は、チタンとし、ピストンヘッドのシールは、PTFEベースのエラストマーで被覆されたキャップシールとし、アクチュエータ試験用の流体は、ジェット燃料と一致する性質の脂肪族炭化水素とした。ピストンヘッドは、500ポンドの荷重でアクチュエータのボア部に対して側面荷重をかけ、ピストンヘッドのシール全体の圧力差は、2800psiだった。ピストンの移動は、−0.010〜+0.010インチのディザ(dithering)、および−0.25〜+0.25インチのストロークとした。Tribaloyコーティングは、コーティングの損壊によって、試験終了時に破損した。このような破損によって、ピストンヘッドの位置で、コーティングは0.0030〜0.0035インチ磨耗し、コーティングが薄い層にさけた箇所の残ったコーティングの厚みは、0.0005〜0.0010インチだった。PTFEキャップシールの重量損失は、0.1102gだった。(1)炭化クロム粒子を有するコーティング、および(2)炭化珪素粒子を有するコーティングを用いて、本発明のコーティングを試験した。図5は、炭化クロム含有コーティングを示す。図6は、炭化珪素含有コーティングを示す。これらの顕微鏡写真は、断面図の写真である。両方のコーティングは、400°F(約204°C)で、1時間熱処理した。同一の試験条件において、炭化クロム含有コーティングは、ピストンの接触部で、深さが0.000004インチの磨耗を示し、シールの重量損失は、0.0188gの減少となった。炭化珪素粒子含有コーティングは、ピストンヘッドで、0.000008インチの磨耗を示し、シールの重量損失は、0.1363gの増加となった。従って、炭化珪素粒子含有コーティングは、完璧な耐摩耗性を示した。炭化クロム含有コーティングは、特に、シール用途に適している。
