| abstract |
The invention relates to a method for treating at least one surface of a solid elastomer part using helium ions. According to the invention, multi-energy ions He + and He 2+ are implanted simultaneously, and the ratio RHe, where RHe=HeVHe 2+ with He + et He 2+ expressed in atomic percentage, is less than or equal to 100, for example less than 20, resulting in very significant reductions in the frictional properties of parts treated in this way. The He + and He 2+ ions are supplied, for example, by an ECR source. |
