【摘要】 <正>In recent years,many attempts have been made to explore the protective capability of grapheme (Gr) as an anti-wear coating for nanotribology.By the molecular dynamics simulations of the nanoindentation of a graphene/Fe(110) system,we provide a new insight into the atomistic mechanism of how graphene protects a metal substrate during.We demonstrate that,in rough contacts,graphene can increase the loading area更多还原
