Innovation
TAC-ON™ (Tetrahedral Amorphous Carbon) thin film has a stable diamond structure containing up to 88% of Tetrahedral bonded sp3 carbon atoms. TAC-ON™ thin film possesses a lot of unique characteristics such as low temperature deposition, super high hardness, excellent adhesion strength with substrate, ultra low friction coefficient, very stable chemical property, high wear resistance and so on. FCVA coated special hydrogen-less diamond carbon thin film can significantly extend the life for various types of molds, tools and parts which will see a remarkable reduction in production cost and improvement in productivity.
