Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0014] like figure 1 As shown, a plasma spraying execution system includes an ignition gas channel, a main gas channel, a powder feeding channel, an air channel and a spray gun 24, and the ignition gas channel is connected to the spray gun 24 after merging with the main gas channel. The main air channel and the powder feeding channel are connected through pipelines and merged into the spray gun 24, and the air channel is connected to the spray gun 24. The gas that feeds in the ignition gas channel is hydrogen, provides fuel gas when the spray gun 24 is ignited, and closes automatically after the spray gun 24 ignites; Oxidation of the spraying material; after the ignition gas channel delivers hydrogen to the spray gun 24 for ignition, the ignition gas channel is closed, the main gas cha...

Abstract

The invention relates to a plasma spraying execution system. The plasma spraying execution system comprises an ignition fuel gas channel, a primary gas channel, a powder feeding channel, an air channel and a spraying gun, wherein the ignition fuel gas channel is jointed with the primary gas channel and then accessed onto the spraying gun; the primary gas channel is connected to the powder feeding channel by virtue of a pipeline and then accessed and jointed onto the spraying gun; and the air channel is accessed onto the spraying gun. The plasma spraying execution system has the advantages of reasonable structural design, convenience in operation, high operation control sensitivity, and the like, can be used for realizing flexible and quick spraying and processing by utilizing automatic control, is high in device safety performance, capable of changing the material supply flow rate according to the actual processing requirements, and suitable for different processing conditions.

Description

technical field [0001] The invention relates to the technical field of plasma spraying processing, in particular to a plasma spraying execution system. Background technique [0002] Plasma spraying is a material surface strengthening and surface modification technology, which can make the surface of the substrate have properties such as wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, wear reduction and sealing. It has the following characteristics: ①Ultra-high temperature characteristics, which is convenient for spraying of high melting point materials; ②The speed of sprayed particles is high, the coating is dense, and the bonding strength is high; ③Because inert gas is used as the working gas, the sprayed materials are not easy to oxidize. However, due to the unreasonable design of the pipeline in the traditional plasma spraying system, the control sensitivity is poor, the adjustabil...
