• the normal load and the sliding distance and the inverse of the hardness of the material [11]. Exploring wear at the nanoscale becomes more and more mandatory with the development of the nanotechnology and its applications [12]. In addition, emerging numerical simulations of nanowear mechanisms are

• (nanowear) have been reported in the literature [17][18][19][20], whereas AFM has been widely used for measuring nanoscale friction [21][22]. In this paper, we propose a new experimental methodology based on circular mode AFM (CM-AFM) to explore wear mechanisms and laws at the nanoscale. It consists of
