Description

Technical Field

[0001] The utility model relates to the technical field of PVD coating application for fuel system plunger shafts, in particular to a clamping device for PVD coating application of a rotating shuttle. 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 surface of a substrate 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 not only deposit metal films, alloy films, but also deposit compounds, ceramics, semiconductors, polymer films, etc.
