Embodiment 1
[0021] A self-lubricating lock cylinder, the surface of the lock cylinder used has a plasma sprayed self-lubricating coating with a thickness of 20-30 μm, and the coating is prepared by the following method:
[0022] (1) Add Cr 3 C 2 Ball mill with NiCr on a planetary ball mill until no more precipitation;
[0023] (2) Add graphene, Ni-coated micron graphite and h-BN to continue ball milling for at least 10 minutes;
[0024] (3) 5 minutes before the ball mill stops, add an organic binder to ball mill to obtain a suspension;
[0025] (4) The suspension is sprayed and granulated to obtain self-lubricating agglomerated particles;
[0026] (5) Plasma spraying the self-lubricating agglomerated particles on the surface of the lock cylinder.

Abstract
The invention discloses a self-lubricating lock cylinder. The surface of the self-lubricating lock cylinder is provided with a plasma sprayed self-lubricating coating layer with a thickness ranging from 20 to 30<mu>m. The plasma sprayed self-lubricating coating layer is capable of reducing friction coefficient and wear rate at the same time, is relatively low in friction coefficient, and possesses wear resistance more excellent than that of Cr coating layers; and wear rate is reduced by 50% or more at different loading.
Description
technical field [0001] The invention relates to the technical field of locks, in particular to a self-lubricating lock cylinder and a preparation method thereof. Background technique [0002] A lockset refers to a device that acts as a seal, including locks, keys and accessories. It is generally interpreted as "a seal that must be opened with a key." Now, in addition to being opened with a key, the lock can also be opened with light, electricity, Instructions such as magnetic, acoustic and fingerprint can be activated. The most widely used lockset is still based on key opening and closing. [0003] A typical lockset includes a lock case and a lock cylinder installed in the lock case. A deadbolt is installed on the lock cylinder, and a lock hole is arranged on the lock case. The lockset also includes: a lock hole stopper whose position can be adjusted Adjustably cover the end of the lockhole away from the deadbolt, and after the driving end of the key of the lock is inserte...
