Patent

CA 2455255

The invention relates to a method for processing and producing a surface of a material with a reproducible degree of lustre and to a press (1) for carrying out said method. The aim of the invention is to increase the stability of the press (1). To achieve this, a press (1) is provided with a coating (3) that consists of carbon with diamond-like layers and that adheres to the surface (2) of the press. Said coating has a layer thickness of between 0.1 and 10 µm and a surface hardness in excess of 1800 HV (Vickers). The attrition of the surface (2) of the press is thus significantly reduced during the processing of abrasion-resistant materials.

L'invention concerne un procédé de traitement et de production d'une surface d'une matière présentant un degré de brillance reproductible, ainsi qu'une presse (1) permettant d'effectuer ce procédé. L'objectif de l'invention est d'accroître la stabilité de cette presse (1). A cet effet, ladite presse (1) est pourvue d'un revêtement (3) qui est constitué de carbone et de couches adamantines et adhère fermement à la surface (2) de la presse. Ce revêtement présente une épaisseur de couche comprise entre 0,1 et 10 µm et une dureté de surface supérieure à 1800 HV (indice de dureté Vickers). Ceci permet de réduire considérablement l'abrasion de la surface (2) de la presse lors du traitement de matières extrêmement résistantes à l'usure.
