摘要
Even though the slipperiness of ice is important both technologically and environmentally and often experienced in everyday life,the nanoscale processes determining ice friction are still unclear.We study the friction of a smooth ice-ice interface using atomistic simulations,and especially consider the effects of temperature,load,and sliding velocity.At this scale,frictional behavior is seen to be determined by the lubricating effect of a liquid premelt layer between the sliding ice sheets.In general,increasing temperature or load leads to a thicker lubricating layer and lower friction,while increasing the sliding velocity increases friction due to viscous shear.
