Sliding component comprising coating intended to be in contact at least partially with lubricant, its tribological system and its use

摘要

Abstract invention patent: "sliding component is coated with a carbon layer including metal to improve the wear behavior and friction for tribological applications in lubricated conditions.The present invention relates to a coating for sliding parts which allows the use of carbon coatings (DLC) type diamond or DLC coatings comprising in combination with lubri - steady dates including molybdenum and / or zinc in such a way that re - tions of sharp) Sgaste and friction in comparison with state of the art is obtained.The coating system, in accordance with this in the prevention, comprises at least a carbon layer comprising metal of type I - C / a) - C: X, whose composition can be expressed as (meac1 -) 1 - BXB with 0.3? The? 0.6 and 0 B? 0,3Where m is a metal or a combination of different metal and X is an element different from me and unlike C or X is a mixture of different elements of T and does not contain C. can be preferably chromium (CR) or molybdenum (MO) and X can be preferably hydrogen (H) or a MIS The fracture of silicon and hydrogen (Si + H).
