Embodiment Construction

[0020] The aforementioned and other technical content, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment.

[0021] The compressor slide of the preferred embodiment of the present invention includes a substrate and a coating on the surface of the substrate.

[0022] The coating consists of three layers, which are as follows from inside to outside: the chromium coating attached to the substrate; the first silicon-containing diamond-like carbon coating attached to the chromium coating; the second silicon-containing diamond-like coating attached to the first silicon-containing diamond-like coating. Two silicon-containing diamond-like carbon coatings. Wherein, the thickness of the chromium coating is 700-800 nanometers; the thickness of the first silicon-containing diamond-like coating is 1200-1300 nanometers; and the thickness of the second silicon-containing diamond-like coating is 800-1000 nano...

Abstract

The invention provides a compressor sliding blade, which comprises a base blade and coating layers attached on the surface of the base blade, wherein the coating layers comprise three layers which are the following layers in sequence from inside to outside: a chromium coating layer attached on the base blade, a first silicon-containing diamond-like coating layer attached on the chromium coating layer and a second silicon-containing diamond-like coating layer attached on the first silicon-containing diamond-like coating layer. The invention has the main advantages that the compressor sliding blade of the invention uses the silicon-containing diamond-like coating layers (DLC-Si), the inner stress is smaller, the combining force between the compressor sliding blade and the base blade is better, the compressor sliding blade has high wear-resistance performance, and air conditioners prepared by the compressor sliding blade have long service life.

Description

technical field [0001] The invention relates to a compressor sliding vane and a surface coating treatment method thereof, in particular to an air conditioner compressor sliding vane with high wear resistance and a surface coating treatment method thereof. Background technique [0002] The life of air conditioner compressors (including new refrigerant compressors and heat pump compressors, etc.) mainly depends on the life of the sliding vanes. When the compressor is working, the sliding vane always has mechanical friction with the stator of the compressor. When the wear on the top of the sliding vane exceeds a certain value, the efficiency of the compressor will drop significantly until it cannot cool. Therefore, improving the wear resistance of the sliding vane can directly improve the life of the compressor. At present, the methods used to improve the wear resistance of the sliding plate include: carrying out surface nitriding treatment on the sliding plate; using PVD tech...
