Problems solved by technology

[0002] The wear of the guide shoe lining for elevators will cause the elevator to vibrate and affect the ride comfort. By increasing the friction coefficient of the shoe lining material, the running stability can be improved. However, if the friction coefficient is too large, the friction force will be too large during the operation of the elevator, and the energy consumption will increase.

Abstract

The invention discloses a ceramic metal nylon composite coating for elevator guide shoe lining protection and a preparation method of the ceramic metal nylon composite coating. The ceramic metal nylon composite coating for the elevator guide shoe lining protection comprises a boron carbide ceramic coating, an aluminum coating and a polyhexamethylene adipamide coating which are sequentially arranged from the position close to the surface to be coated to the position away from the surface to be coated; the thickness of the boron carbide ceramic coating is 200 [mu] m-400 [mu] m, the thickness of the aluminum coating is 100 [mu] m-200 [mu] m, and the thickness of the polyhexamethylene adipamide coating is 200 [mu] m-400 [mu] m. The composite coating comprises the boron carbide ceramic coating, the aluminum coating and the polyhexamethylene adipamide coating which are sequentially arranged from the position close to the surface to be coated to the position away from the surface to be coated, the wear resistance and impact resistance of the composite coating are obviously higher than those of the surface of a steel guide shoe lining, the abrasion loss is reduced by about 55% after the composite coating is abraded for 80 h, the guide shoe lining can be effectively protected, and the service life of the elevator guide shoe lining is prolonged.

Description

technical field [0001] The invention belongs to the technical field of thermal spraying treatment, and in particular relates to a ceramic-metal-nylon composite coating for elevator guide shoe lining protection. Background technique [0002] The wear of the lining of the guide shoes used in elevators will cause the elevator to vibrate and affect the ride comfort. The running stability can be improved by increasing the friction coefficient of the shoe lining material. However, the friction coefficient is too large, which will lead to excessive friction and increased energy consumption during the operation of the elevator. Finding a boot lining material that can achieve friction reduction to reduce energy consumption, and at the same time has wear resistance and impact resistance is the key to prolonging the service life of the boot lining, reducing costs and improving the application of the boot lining material. [0003] At present, the commonly used guide shoe lining material...
