It is a low-temperature PVD coating using advanced vacuum plasma technology.
The Celtes X coating for semiconductor mold dies is a low-temperature PVD coating using advanced vacuum plasma technology. The chromium nitride coating (CrxNy) with a thickness of 2 to 5 μm, deposited by the PBS (Plasma Booster Sputtering) process, has a Vickers hardness of over 1800 and demonstrates excellent wear resistance against abrasive wear from silica particles. Additionally, for steel substrates, it is also possible to perform re-coating processing of the coating on the discharge machined surface. For more details, please download the catalog.

basic information
**Features** - In friction and wear tests with SiC balls, it shows about 10 times the wear resistance of TiN coating and equivalent to DLC coating. - Has good tribological properties. → The friction coefficient with SiC is low at 0.29. - The contact angle of pure water droplets is over 100 degrees, indicating higher hydrophobicity than other hard thin films. - Exhibits good release properties against epoxy resin. → The surface free energy calculated from the contact angle measurements of pure water and methylene iodide is 25 mN/m, making reactions on the surface less likely. - Environmental impact reduction (RoHS compliant).

Company information
By adopting special sputtering and plasma CVD processes, we provide high-quality coatings with excellent adhesion even at low-temperature treatments below 180 degrees, along with high film thickness precision and outstanding tribological properties such as wear resistance, seizure resistance, and low friction coefficient, all based on abundant achievements and experience, with short delivery times. In particular, coatings from the Seltes brand, such as CrN-based coatings (Seltes X, N) as alternatives to Cr plating and Seltes DLC, which have excellent adhesion even under high surface pressure, are highly regarded in plastic molding molds, press molds, automotive parts, and high-precision sliding components. We also conduct various evaluations of metal surfaces and thin films, as well as defect analysis, using surface cleanliness measurement instruments like Corona Surf.
