Abstract:Graphene on a stainless steel substrate will appear as localized bulges, and these bulges will lead to large fluctuations in friction force, which is the key to influencing the lubrication efficiency of graphene. Here, the effect of normal load on the nanofriction behavior of the bulged graphene on a stainless steel substrate is investigated. In the normal load study interval from 20 to 110 nN, an increment of 10 nN of normal load can increase friction force the more the normal load increases, and the two are … Show more
