磨损和腐蚀是机械设备材料损失和设备失效的主要原因之一，尤其是在载流摩擦条件下，两者相互作用，相互加剧。为此，研究了一种新型离子液体添加剂(IL-16)，以同时提高钢-钢摩擦副在导电条件下的耐磨和耐蚀性能。当IL-16含量为1.6wt%时，在1.5A的负载电流下，摩擦系数降低58.8%，磨损量减少10倍，接触电阻仅为37M omega，这是由于IL-16离子液体添加剂在摩擦副表面形成了稳定的物理吸附膜，阻碍了与腐蚀反应有关的电荷和产物的转移。
Wear and corrosion are one of the main causes of material loss and equipment failure in mechanical equipment, especially under current-carrying friction conditions, which interact and exacerbate each other. Herein, a new ionic liquid additive (IL-16) was studied to simultaneously improve the anti-wear and anti-corrosion properties of steel-steel friction pair under conductive conditions. The coefficient of friction decreased by 58.8% at 1.6 wt% IL-16 content under the load current of 1.5 A, the wear was reduced 10 times, and the contact resistance was only 37 m omega, owing to the IL-16 ionic liquids additive forming a stable physical adsorption film on the surface of the friction pair to hinder the transfer of charges and products related to the corrosion reaction.
