Title
(EN) ROTARY COMPRESSOR
(FR) COMPRESSEUR ROTATIF
(JA) ロータリ圧縮機
Abstract
(EN)
A first vane (127S) of a rotary compressor (1) is provided with a base material (127SB), a diamond-like carbon coating film (127SD) and a nitrided film (127SN). The base material (127SB) contains a nitride-forming element. The diamond-like carbon coating film (127SD) is made from diamond-like carbon, and coats a tip (127SS), which is in contact with a first ring-shaped piston (125S), of the first vane (127S). The nitrided film (127SN) contains a nitride of the nitride-forming element, and is formed between the base material (127SB) and the diamond-like carbon coating film (127SD). The effective film thickness of the diamond-like carbon coating film (127SD) is 0.20 μm or more, wherein the effective film thickness is measured by carrying out a micro slurry-jet erosion test using 3-μm spherical alumina particles.

Une première aube (127S) d'un compresseur rotatif (1) est pourvue d'un matériau de base (127SB), d'un film de revêtement de carbone sous forme de diamant amorphe (127SD) et d'un film nitruré (127SN). Le matériau de base (127SB) contient un élément de formation de nitrure. Le film de revêtement de carbone sous forme de diamant amorphe (127SD) est constitué de carbone sous forme de diamant amorphe, et recouvre une pointe (127SS), qui est en contact avec un premier piston en forme d'anneau (125S), de la première aube (127S). Le film nitruré (127SN) contient un nitrure de l'élément de formation de nitrure, et est formé entre le matériau de base (127SB) et le film de revêtement de carbone sous forme de diamant amorphe (127SD). L'épaisseur de film efficace du film de revêtement de carbone sous forme de diamant amorphe (127SD) est de 0,20 μm ou plus, l'épaisseur de film efficace étant mesurée par réalisation d'un test d'érosion par micro jet de bouillie utilisant des particules d'alumine sphériques de 3 μm.
(JA)
ロータリ圧縮機(1)の第1ベーン(127S)は、母材(127SB)とダイヤモンド状炭素皮膜(127SD)と窒化処理膜(127SN)とを備えている。母材(127SB)は、窒化物形成元素を含んでいる。ダイヤモンド状炭素皮膜(127SD)は、ダイヤモンド状炭素から形成され、第1ベーン(127S)のうちの第1環状ピストン(125S)に当接する先端(127SS)を被覆している。窒化処理膜(127SN)は、窒化物形成元素の窒化物を含有し、母材(127SB)とダイヤモンド状炭素皮膜(127SD)との間に形成されている。ダイヤモンド状炭素皮膜(127SD)に球形アルミナ3μm粒子を用いてマイクロスラリージェットエロージョン試験を施すことにより測定される有効膜厚は、0.20μm以上である。
