Description

Technical Field

[0001] The utility model relates to the technical field of PVD coating of the long and narrow surface of a compressor sliding vane, in particular to a clamp used for PVD coating of the long and narrow surface of a compressor sliding vane. Background Art

[0002] PVD technology involves using physical methods under vacuum conditions to vaporize the surface of a material source (solid or liquid) into gaseous atoms or molecules, or partially ionize it into ions. Through a low-pressure gas (or plasma) process, a thin film with specialized properties is deposited on the substrate surface. PVD is a major surface treatment technique. PVD coating technologies are primarily categorized into three types: vacuum evaporation, vacuum sputtering, and vacuum ion plating. The main methods of physical vapor deposition include vacuum evaporation, sputtering, arc plasma, ion plating, and molecular beam epitaxy. Corresponding vacuum coating equipment includes vacuum evaporation, sputtering, and vacuum ion plating machines. With advancements in deposition methods and technologies, physical vapor deposition can deposit not only metal and alloy films, but also compounds, ceramics, semiconductors, and polymer films.

[0003] When applying PVD coating to compressor vanes, it is often sufficient to coat only the long and narrow surfaces. However, the fixtures currently used for PVD coating of compressor vanes cannot stably fix the compressor vanes because the compressor vanes are relatively thin. If the compressor vanes move during coating, the coating effect will be affected. Utility Model Content
