“…For studies at the micro-and nano-scale we must, however, relate to studies of non-hydrogenated diamond-like carbon (DLC) coatings. These amorphous films are a mix of sp 3 tetrahedral bonding (like in single-crystal diamonds) and sp 2 trigonal bonding (like in single-crystal graphite), and usually deposited by physical or chemical vapor deposition techniques 14 . Since Bhushan published the first nanotribological study of amorphous carbon films using an atomic force microscope (AFM) 15 , there have been many studies about the nanotribological properties of carbon-based coatings, as it has been reviewed for dry and lubricated conditions [16][17][18][19][20][21][22] .…”

Cryogenic treatments are increasingly used to improve the wear resistance of various steel alloys by means of transformation of retained austenite, deformation of virgin martensite and carbide refinement. In this work the nanotribological behavior and mechanical properties at the nano-scale of cryogenically and conventionally treated AISI 420 martensitic stainless steel were evaluated. Conventionally treated specimens were subjected to quenching and annealing, while the deep cryogenically treated samples were quenched, soaked in liquid nitrogen for 2 h and annealed. The elastic–plastic parameters of the materials were assessed by nanoindentation tests under displacement control, while the friction behavior and wear rate were evaluated by a nanoscratch testing methodology that it is used for the first time in steels. It was found that cryogenic treatments increased both hardness and elastic limit of a low-carbon martensitic stainless steel, while its tribological performance was enhanced marginally.
