TS-VTI is a trusted provider of superior DLC coating services. Diamond-like carbon delivers extreme hardness and an ultra-low coefficient of friction in a single thin film, combining the wear resistance of diamond with the lubricity of graphite. With low deposition temperatures starting at 150 °C, DLC is well suited to tempered tool steels, hardened bearing steels, medical-grade stainless, and other temperature-sensitive substrates.
As part of the HEF Group, TS-VTI's DLC coating services draw on the full Certess Carbon family, a proven line of diamond-like carbon chemistries refined across HEF production sites worldwide. Whether the application is a general-purpose a-C:H film for automotive components or a tetrahedral amorphous carbon (ta-C) film for the most severe tribological duty, our coating engineers match the right chemistry, underlayer, and thickness to your parts. Send us your components, and we return them coated to specification.
