详情描述

Ta-C coating is a hydrogen-free carbon element coating, also known as tetrahedral amorphous diamond-like coating. It boasts a high sp/sp3 bond ratio, with the sp3 diamond content ranging from 65% to 85%, and its Vickers hardness reaches up to 5000-7000 HV. Ta-C has a certain level of transparency, and when the coating thickness is less than 1 micron, the workpiece will display a rainbow color due to the interference of light. As the coating thickness increases, the color changes to gray-black. The excellent adhesion resistance and high hardness of Ta-C coating make it play a significant role in the mold and cutting tool industry.
