Problems solved by technology

[0004] However, due to the use of environmentally friendly new refrigerants, the original compressor and its spare parts can no longer fully meet the requirements of the new refrigerant medium environment, including the internal working pressure of the compressor, which increases from 1.5Mpa to 2Mpa at R22 to R410A. 3Mpa~4Mpa, the internal working pressure of the latest Japanese technology compressor has even reached above 11Mpa
Therefore, in the new refrigerant environment, the friction of the "heart part" sliding vane of the compressor is intensified, and the original surface treatment technology of the sliding vane can no longer meet the demand. Green high-performance surface coating new materials and technologies

Abstract

The invention discloses a film for raising the abrasion resistance of a compressor slide plate and a preparation method thereof. The film provided by the invention is positioned on the surface of the slide plate matrix and has a multilayer structure, wherein the first layer, close to the surface of the slide plate matrix, is a linear ion source auxiliary depositional metal simple substance adhesive layer; the second layer is a metal simple substance transition layer; the third layer is a metal hard carbide transition layer; and the fourth layer is a diamond-like carbon layer. In comparison with the prior art, by the optimization design of the film structure on the surface of the slide plate matrix and the optimization of the preparation technology, the produced film provided by the invention has advantages of high hardness, low friction coefficient, high wear resistance and corrosion resistance, smooth surface, uniform thickness and high adhesion strength, and can be used to raise the abrasion resistance of the compressor slide plate so as to enable the slide plate matrix to be used in the environments of R410A or a higher-level novel refrigerant and a lubricant and prolong the service life of the slide plate matrix.

Description

technical field [0001] The invention relates to the technical field of compressor sliding vanes, in particular to a film for improving the wear resistance of compressor sliding vanes and a preparation method thereof Background technique [0002] In recent years, extreme climate change has attracted more and more attention, and environmental protection has become the hottest topic in the world. The continuous destruction of the ozone layer and the gradual warming of the climate are two major problems that human beings are facing today. Environmental issues. Freon, which is widely used in electrical refrigeration devices such as automobiles, air conditioners, and refrigerators, is the main participant in the destruction of the ozone layer and the creation of the greenhouse effect. At high altitude, under the irradiation of ultraviolet rays, new substances and chlorine ions will be generated, making the ozone layer thinner and thinner. In some areas, such as the Antarctic sky, ...
