Patent ID: 7074460

Claim:
Method for treating the surface of a part ( 7 ), which consists in bringing at least one activated chemical species into contact with a surface of the part ( 7 ), characterised in that the activated chemical species is generated in a gaseous medium containing at least two of the elements carbon, nitrogen, boron, and oxygen, so that the activated chemical species is constituted by at least two of the elements carbon, nitrogen, boron, and oxygen, the activated chemical species being generated in the form of an excited neutral species constituted by at least two elements taken from C, N, B, and O by generating a plasma in the gaseous medium inside a treatment chamber ( 1 ) and outside a container ( 5 ) containing the part to be treated communicating with the treatment chamber ( 1 ) by an interstice whose opening dimension (e) prevents plasma ignition through the interstice (e), the species generated by the plasma remaining reactive with respect to the surface of the part ( 7 ) after passing into the interstice.
