Title (EN) ANTIFRICTION BEARING FOR USE IN A CORROSIVE ENVIRONMENT
(FR) PALIER A ROULEMENT, UTILE DANS UN ENVIRONNEMENT CORROSIF
Abstract:
(EN) An antifriction bearing (A) that operates in an environment rendered corrosive by a halogen gas or a hydrohalogen acid has races (2 and 4) that are formed from stainless steel and rolling elements (6) that roll along opposed raceways (8 and 10) on the races (2 and 4). The stainless steel of the races (2 and 4) constitutes a substrate (18) over which a coating (C) extends, and that coating contains amorphous carbon in the form of diamond-like carbon (DLC) which is hard and firmly bonded, so that it does not flake, and also carbides to better resist wear. The coating (C) may also contain hydrocarbons. Indeed, the amorphous carbon and hydrocarbons form a matrix in which the carbides are embedded.
(FR) Ce palier à roulement (A), fonctionnant dans un environnement rendu corrosif par un gaz halogène ou par un acide hydrohalogéné, comprend des bagues de roulement (2 et 4) en acier inoxydable, ainsi que des éléments de roulement (6), lesquels roulent le long de pistes opposées (8 et 10) ménagées sur les bagues de roulement (2 et 4). L'acier inoxydable des bagues de roulement (2 et 4) constitue un substrat (18) sur lequel s'étend un revêtement (C) contenant du carbone amorphe sous la forme de carbone du type diamant, dur et solidement lié, de manière à ne pas s'écailler, ainsi que des carbures permettant une meilleure résistance à l'usure. Le revêtement (C) peut également contenir des hydrocarbures. En fait, le carbone amorphe et les hydrocarbures forment une matrice dans laquelle les carbures sont encastrés.
