    Abstract: A method for plasma treating a target surface of a part, including: obtaining the target surface on the part; placing the part in a chamber of a plasma generator; evacuating the chamber to a pressure of between 10-6 and 10 mbar; injecting a suitable gas into the chamber until a pressure in the chamber of between 10-4 and 102 mbar is reached; generating an electric current discharge within the chamber, via an electric generator, in order to generate a plasma; exposing the target surface of the part to the plasma for a predefined period of time depending on the power of the electric current discharge, on the gas injected into the chamber and on the material of the target surface, so as to deteriorate the surface condition of the target surface in order to increase the roughness thereof to make the target surface mat or more mat.
