Description

Technical Field

[0001] The utility model relates to the technical field of local PVD coating of a rotor shaft, in particular to a shielding device for local PVD coating of a rotor shaft. Background Art

[0002] PVD technology refers to a technology that physically vaporizes the surface of a material source (solid or liquid) into gaseous atoms or molecules, or partially ionizes them into ions under vacuum conditions, and deposits a thin film with a certain special function on the substrate surface through a low-pressure gas (or plasma) process. PVD technology is one of the main surface treatment technologies. PVD coating technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion coating. The main methods of physical vapor deposition include: vacuum evaporation coating, sputtering coating, arc plasma coating, ion coating, and molecular beam epitaxy, etc. The corresponding vacuum coating equipment includes vacuum evaporation coating machines, vacuum sputtering coating machines, and vacuum ion coating machines. With the improvement of deposition methods and technologies, physical vapor deposition technology can deposit not only metal films and alloy films, but also compound films, ceramic films, semiconductor films, polymer films, etc.

At present, the clamping mechanisms on the market do not have a partial shielding function. After manual shielding operation, it needs to be put into the fixture for coating. The operation is cumbersome and the coating efficiency is low. Content of the Utility Model
