Forms a coating with a hardness of 50 GPa or higher. Excellent adhesion to tool steel and SUS304, with processing that minimizes thermal effects. Materials with test results will be provided.
"Celtes TC" is a technology that forms a coating with a ta-C structure achieving a hardness of 50 GPa. It can be processed at low temperatures below 180°C, allowing for treatment that minimizes thermal impact on steel materials. It also exhibits excellent adhesion to stainless steel in addition to tool steel. Compared to the a-C:H based coating "Celtes DCY," it achieves approximately twice the hardness and superior wear resistance. It has already been mass-produced for automotive engine components used under harsh conditions, such as pushless piston pins, and contributes to the longevity of non-ferrous metal processing molds. 【Features】 - Capable of forming a coating with excellent hardness and wear resistance while minimizing thermal impact. - Can also form thick films of over 2 μm. - High resistance to adhesion against aluminum alloys has also been confirmed. *You can view documents with test results by downloading the PDF.

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.
