Problems solved by technology

These methods can be applied to some fields in industrial production, but there are still some deficiencies. Electroplating will have problems such as missing plating, burrs, and coating damage; electroless plating needs to immerse the sample in an aqueous solution, and the adhesion is poor, and the surface of the sample is still Special treatment is required; advanced processes such as laser processing have high requirements for equipment, and the process is relatively complicated
In addition, there are etching, screen printing, coating, sol-gel and other film-forming methods, but the film-forming effect is not good, and post-treatment processes are required

Embodiment 1

[0043] The nanoparticle aerosol preparation device communicates with the vacuum sample chamber through the critical hole, and the surface coating component and the sample multi-axis linkage platform are installed in the vacuum sample chamber, and the coated sample is placed on the sample multi-axis linkage platform. The nano-aerosol is prepared by the aerosol device, then passes through the critical hole with the airflow, enters the surface coating part, and is coated on the sample of the multi-axis linkage platform of the sample through the nozzle. With the arbitrary movement and rotation of the sample, a thin film with uniform thickness is formed to realize the all-round coating of nanoparticles on the surface of the sample, and then the surface coating is heat-treated by the heat source in the sample cavity.

Abstract

The invention discloses a surface coating method and equipment. The surface coating equipment includes a nanoparticle aerosol preparation device, a vacuum sample chamber, and a sample multi-axis linkage platform; the nanoparticle aerosol preparation device includes a nanoparticle aerosol A preparation chamber and a coating part connected to the nanoparticle aerosol preparation chamber; the vacuum sample chamber is provided with a connection hole for the coating part; the sample multi-axis linkage platform is placed inside the vacuum sample chamber, and the The sample multi-axis linkage platform is connected with the sample stage; the coating part extends into the vacuum sample chamber through the connecting hole of the coating part to the position of the sample. This technology can replace the current traditional coating processes such as electroplating, chemical plating, physical vapor deposition, and chemical vapor deposition. It can use nano-aerosols of any material to coat the surface of samples of any shape, size, and structure. The operation is simple and easy. Realized, and has very wide applicability.

Description

technical field [0001] The invention relates to the technical field of coating equipment, in particular to a surface coating method and equipment. Background technique [0002] In recent years, nanotechnology has been developed in a long-term. In industrial production, it is generally necessary to coat a protective layer on the surface of the product, not only to repair a large number of mechanical parts, but also to endow the surface of the workpiece with wear-resistant, corrosion-resistant, and High temperature, oxidation resistance, thermal shock resistance, radiation resistance, heat insulation, insulation and other engineering properties. At present, there are many methods of surface coating. Some researchers use the electroplating method to use the iron and steel parts whose surface has been degreased as the cathode, and the pure copper plate as the anode. Copper plating is carried out in an alkaline electroplating solution; some people use the electroless plating met...
