Description

Technical Field

[0001] The utility model relates to the technical field of PVD coating application on the surface of bearing rollers, in particular to a fixture for PVD coating application on the surface of large bearing rollers. Background Art

[0002] The PVD technology refers to a technology that, under vacuum conditions, physically vaporizes the surface of a material source (solid or liquid) into gaseous atoms or molecules, or partially ionizes them into ions, and deposits a thin film with a certain special function on the surface of a substrate through a low-pressure gas (or plasma) process. The PVD technology is one of the main surface treatment technologies. The 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 a vacuum evaporation coating machine, a vacuum sputtering coating machine, and a vacuum ion coating machine.
