DLC (Diamond Like Carbon)

The increase in deposition of the DLC MIDA treatment occurs through the PACVD (Plasma Assisted Chemical Vapor Deposition) coating process by which it is possible to obtain deposits of amorphous carbon with diamond-like characteristics. The deposition is performed inside a vacuum chamber where gases are injected, ionized and induced to a plasma state. In this state the gases interact with the surface of the treated objects positioned inside the chamber depositing a layer of amorphous carbon. Moreover the PACVD deposition process makes it possible to limit the temperature of the substrate so avoiding deformations and changes in the structure of the alloys; in this way it is also possible to treat materials with a low melting point like aluminum.The well-adhering and homogeneous coating is characterized by excellent chemical resistance and is unattackable by acid or alkaline solutions and by organic agents
