[en] Acrylonitrile-Butadiene Rubber (NBR) is one of the widely used synthetic rubbers currently used for a variety of non-tire rubber products. Ion implantation is foreseen to be an efficient way to improve the NBR surface characteristic such as lower coefficient, higher resistance. Ion implantation with N⁺ and H⁺ ions was carried out to treat NBR surface to understand the irradiation influence on functional properties of the vulcanizates, like friction and hardness on Peking University (PKU) ion source test bench recently. Analysis on friction coefficient, hardness. thermal aging resistance, tribology and wear resistance were done after ion implantation. (authors)
