Embodiment 1

[0021] A slide rail for an automobile sliding door, the surface of the slide rail has a 20 μm thickness of plasma sprayed Cr 3 C 2 -NiCr-graphene coating.

[0022] The surface of the slide rail has plasma sprayed Cr 3 C 2 -NiCr-graphene coating, prepared by the following method:

[0023] The coating material is powdered using a planetary ball mill and a centrifugal spray granulator. Its process includes:

[0024] (1) Add Cr 3 C 2 Ball mill with NiCr on a planetary ball mill until no more precipitation;

[0025] (2) Add graphene and continue ball milling for at least 10 minutes;

[0026] (3) 5 minutes before the ball mill stops, add an organic binder to ball mill to obtain a suspension;

[0027] (4) The suspension is sprayed and granulated to obtain Cr 3 C 2 -NiCr-graphene agglomerated particles.

[0028] By plasma spraying the Cr 3 C 2 -NiCr-graphene agglomerated particles sprayed onto the slide. For the plasma spraying, the current is 550A, the voltage is 30V, ...

Abstract

The invention discloses a sliding rail for an automobile sliding door. The surface of the sliding rail is provided with a plasma spraying Cr3C2-NiCr-graphene coating with a thickness of 20-30 [mu]m. The coating reduces friction coefficient and wear rate simultaneously, and the sliding door has a low friction coefficient and excellent wear resistance. Under each load, the wear rate is reduced by 50% or above compared with a base body.

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 101169026B 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 the...
