低能强流离子注入丁腈橡胶的表面改性(英文)

Modification of NBR Surface by Low Energy and High Current Ion Implantation

丁腈橡胶是一种广泛使用的合成橡胶,目前应用于各种非轮胎制品。离子注入被认为是一种提高丁腈橡胶表面特性的有效手段,比如降低摩擦系数、提高耐抗性等。最近,为了理解辐照效应对于硫化橡胶的功能特性如摩擦系数和硬度等的影响,利用北京大学离子源测试平台将N^+和H^+注入丁腈橡胶表面进行研究。离子注入完成以后,对丁腈橡胶表面的摩擦系数、硬度、耐热老化性能、摩擦特性以及耐磨损性能进行了分析。

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.
