Problems solved by technology

Since the X-ray tube is a vacuum device, the heat conduction in the tube is quite unsatisfactory
If the heat generated by the target disk is not dissipated in time, it will inevitably affect the electric vacuum performance of the ray tube, resulting in a decrease in the vacuum degree in the ray tube, a decrease in imaging resolution, and at the same time affecting the service life of the ray tube

Abstract

The invention discloses a stainless steel wet hydrogen preparation method and application for improving thermal emissivity, and belongs to the technical field of coating materials. The method includes the following steps: S1: substrate treatment, S2: spraying powder preparation, S3: coating preparation; by spraying double coatings on the surface of the stainless steel substrate, the present invention not only improves the bonding force and wear resistance of the coating and its surface, but also The heat dissipation capacity of the inner surface of the tube shell is greatly improved. At the same time, by adding hollow graphene with a three-dimensional structure in the first coating, not only the heat dissipation capacity of the inner surface of the stainless steel tube shell is improved, but also graphene itself has a very high thermal conductivity. Through laser etching on the surface of the second coating, a number of grooves are formed on the surface, which increases the surface area of ​​the second coating and accelerates the heat conduction and heat dissipation of the coating. performance, further improving the thermal emissivity coefficient, making the thermal emissivity coefficient of the coating as high as 0.93‑0.96.

Description

technical field [0001] The invention belongs to the technical field of coating materials, and in particular relates to a preparation method and application of stainless steel wet hydrogen for improving thermal radiation coefficient. Background technique [0002] The rotating anode X-ray tube is a high-vacuum electric vacuum device. Its working principle is to apply a high voltage (generally 125-150kV) to the positive and negative terminals of the X-ray tube, and the electron beam emitted by the cathode is under the action of a high-vacuum high-voltage electric field. , X-rays are generated by electron bombardment on the anode target surface, only a small part of the kinetic energy of the electrons bombarded on the anode surface is converted into X-rays, and about 98% of the electron kinetic energy is converted into heat energy through a complex energy conversion process, making the target disk temperature rise rapidly. Since the X-ray tube is a vacuum device, the heat condu...
