In this study, the structure and properties of multilayer coatings consisting of alternating CrN/TiN layers on C11000 copper and aged C 17200 alloy are analyzed. Coatings with a total thickness of about 4 μm have been obtained by the method of cathode-arc deposition using two targets made of chromium and titanium. The microhardness of the applied coatings reached 14 GPa. The adhesive strength is investigated by scratch testing in which the destruction of coatings on copper and copper-beryllium alloy substrates occurs at loads up to 10 and 20 N, respectively. The behavior of the multilayer coatings during tribological tests with boundary lubrication is studied with simultaneous registration of acoustic emission (AE) signals. The results obtained indicate that the friction coefficients decrease from 0.11 to 0.07 with a load increase from 5 to 10 N and behave the same for coatings on copper and beryllium bronze substrates.
