Problems solved by technology

The working environment of the valve is particularly harsh, high temperature (about 2200 degrees), high pressure (6-10MPa), high wear and high movement frequency (when the engine is 3000 rpm, the valve opens and closes 1500 times / min). The service performance is obviously reduced, resulting in a significant shortening of the service life of the valve

Abstract

The invention discloses a valve with the PVD coated surface and relates to the technical field of engine parts, in particular to the technical field of engine gas distributing mechanisms. The valve comprises a valve body, and a wear-resistance PVD coating is arranged on the periphery of the valve body. The valve is made of the material of ustenitic stainless steel 21-4N, and the wear-resistance PVD coating with the certain thickness coats the surface by the vapor phase deposition method. The valve has the temperature resistance, high-temperature oxidation resistance, corrosion resistance and impact resistance, the fine-performance engine can be met, the performance is maintained in the high temperature state, and the service life of the valve can be prolonged.

Description

technical field [0001] The invention relates to the technical field of engine parts, in particular to the technical field of engine valve trains. Background technique [0002] As a very important part of the engine, the valve should have the following points as the engine develops in the direction of high speed, high power, low emission and low energy consumption: (1) good wear resistance; (2) good wear resistance Thermal, good thermal conductivity; (3) It can still maintain its hardness and strength under high temperature and high pressure, and can withstand impact; (4) It will not oxidize and corrode under high temperature; (5) The valve is light in weight. The working environment of the valve is particularly harsh, high temperature (about 2200 degrees), high pressure (6-10MPa), high wear and high movement frequency (when the engine is 3000 rpm, the valve opens and closes 1500 times / min). The service performance is obviously reduced, resulting in a significant shortening ...
