PACVD, the key to
diamond-like coatings

PACVD uses a plasma, most often generated by mid-frequency pulsed bias, to crack precursor gases at relatively low temperatures. Using hydrocarbon gases such as acetylene (C₂H₂) can result in highly wear-resistant DLC coatings – a mainstay coating in many industries – which can be doped with Si or other elements to tune the coating characteristics. PACVD DLC plus magnetron sputtering makes a smooth, well-adhering coating stack with high hardness, low friction and excellent wear resistance.
