What is Ta-C film

Ta-C thin film is the abbreviation of Amorphous Tetrahedral Amorphous Carbon (Tetrahedral Amorphous Carbon).Ta-C thin film is based on carbon base material, and adopts cathodic magnetic filtration vacuum arc technology, which filters out the sp3 bonds in carbon atoms to rearrange them, and realizes the microcrystalline structure with high sp3 bonds. The amorphous tetrahedral diamond-like film developed by this technology has excellent properties such as ultra-high hardness, low coefficient of friction, corrosion resistance, etc. Its tribological, chemical, optical and physical properties are the closest to those of natural diamond at present. At present, the most important and cutting-edge technical index to measure the quality of diamond-like film is its sp3 content, and the sp3 bond content of Ta-C film developed by Golden House has reached more than 80%, and this index is the highest index of similar films disclosed in the world at present. This indicates that our technology has created the international most advanced level.
