Coating thickness control device for preparing amorphous-nanocrystalline coating based on supersonic spraying

Abstract

The invention relates to a coating thickness control device for preparing an amorphous-nanocrystalline coating based on supersonic spraying. The coating thickness control device for preparing the amorphous-nanocrystalline coating based on supersonic spraying comprises a connection column and an installation base plate fixedly connected with the connection column. A drive assembly is installed on the upper part of the installation base plate. A transmission assembly connected with the drive assembly is installed in the middle of the installation base plate. The transmission assembly is connected with two stirring plates. A sliding groove is formed in the upper part of the installation base plate. The drive assembly comprises a moving frame, a rocker, two transmission rods and a motor fixedly installed on the installation base plate. The motor is connected with the rocker. The moving frame is installed on the sliding groove in a vertically sliding manner. The moving frame is provided with a matching groove which is in fit with the rocker in sliding and hinged manners. The upper end of each transmission rod is hinged to the moving frame. According to the coating thickness control device for preparing the amorphous-nanocrystalline coating based on supersonic spraying, a sprayed metal powder coating is inserted from the upper part of the middle portion and are spread towards the twosides to be smeared, namely automatic flattening of the sprayed metal powder coating is achieved, and therefore the effect of guaranteeing the flatness of a spraying repair surface is achieved.

Description

technical field [0001] The invention relates to the field of repair and protection processing by supersonic spraying, in particular to a coating thickness control device for preparing amorphous and nanocrystalline coatings based on supersonic spraying. Background technique [0002] In the field of remanufacturing processing, the supersonic spraying method is used for the repair work of the processing tool, the surface of the round roller and the protection work of the equipment surface, which can spray the repair material to the corresponding equipment with metal powder through the spray gun. Surface, so that the metal powder forms a nano-coating of iron-based materials, and then solidifies through water crystals to form amorphous nano-crystals to achieve the repair effect. But in the actual spraying process, because the muzzle of the spray gun is round, so when the spray gun is moving in a straight line, due to the coverage effect, the metal powder coating produced by the s...

Problems solved by technology

But in the actual spraying process, because the muzzle of the spray gun is round, so when the spray gun is moving in a straight line, due to the coverage effect, the metal powder coating produced by the spraying is more and thicker in the middle, and thinner and thinner on both sides. If the situation occurs, it will be difficult to ensure the flatness of the repaired surface if it is not dealt with
