Abstract

The invention discloses a sliding rail for sliding doors of automobiles. A graphene nickel-based composite coating with a thickness of 20-30 microns is arranged on the surface of the sliding rail. Through the composite coating, the friction coefficient and wear rate are reduced at the same time, and the composite coating has a relatively low friction coefficient and has abrasive resistance more excellent than that of Cr coatings. Under each load, the wear rate is reduced by more than 50% than a matrix.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a slide rail for an automobile sliding door. Background technique [0002] Automobiles, particularly multifunctional automobiles, such as MPVs or commercial vehicles, have rear doors that are opened manually or electrically. Its opening method is different from the pull-out type of traditional cars, but slides back and forth. The sliding depends on the sliding mechanism installed on the upper and lower sides of the car door. Generally, the guide rail cooperates with the locking mechanism to realize the front and rear sliding of the car door, which has achieved the purpose of saving opening and closing space. [0003] CN 101169026 B discloses a sliding door structure for an automobile, which utilizes at least one guide mechanism that guides the door body in the front-rear direction of the vehicle to allow the door body to slide relative to the opening of the vehicle body in th...
