In this paper, we describe molecular level design and synthesis of a series of nanocomposite coatings providing extreme resistance to wear and scuffing and very low friction in lubricated test environments. The ingredients or chemistry of nanophases in these films were selected strategically so that during lubricated contacts, they can form low-shear and protective boundary films by favorably reacting with some of the additives in formulated oils. Among others, MoN-Cu coatings had the greates beneficial effects in lowering friction and increasing resistance to wear and scuffing. In fact, these films were impossible to scuff even under the maximum loading and sliding conditions that we could establish in our test machines. In this paper, we will present the main characteristics of these nanocomposite coatings and discuss in details the fundamental tribological mechanisms that control their superior friction, wear, and scuffing behaviors under severe sliding conditions.
