Interaction in the Ti-N-O system at the atomic level with the formation of titanium oxinitride results in a significant increase in the durability of the materials studied. The regularities of the wear of fragile bodies (diamond in conditions of grinding with diamond particles) under conditions of elastic-adhesive contact are studied. The presence of tensile stresses on the periphery of the abrasive particles (at the voltage of the comprehensive compression at the center of the contact) leads to the formation of the geometry of the crack and to the tearing of the surface areas within the contact area. It is with this mechanism of adhesive wear of the diamond during its polishing that the bonded adhesion craters in the contact zones are fixed by the semicircular cracks Product Description popup.authors Ведель Дмитро Вікторович Григорьев Олег Миколайович Жунківський Григорій Леонтійович Мазур Петро Володимирович Мелах Людмила Михайлівнам.
