the present invention relates to a process for depositing a coating on parts to be coated, in particular for dies for the trafilazione plastics at the timecomprising the stages of: - ionic cleaning pieces from play, and deposition by sputtering of at least one coating deposition, such as ionicamente assistedthese stages are carried out by means of a cold cathode ion source universal energy reduced, conglobate into a single system with a cathode of sputtering.by using a gas for the generation of electricity.the present invention also concerns a coating obtained by this process and a sector for the trafilazione plastics the fusions coated with such a coating.
