The aim of the study was to conduct a comparative analysis of the cavitation erosion resistance of thick (up to 20 μm) Cr-C coatings by means of the rotating-disk testing method. An experimental study was carried out of the process of cavitation destruction of Cr1 8 Ni1 0 Ti stainless steel samples with Cr-C thick coatings depending on the carbon concentration in the coating. Nanocrystalline thick coatings of Cr-C were deposited by using the cathodic arc evaporation (Arc PVD) method. The results showed that the erosion rate of the coated samples was more than four times less than that of the uncoated sample. The Cr-C samples coated with 28.8 at % carbon content demonstrated less surface damage compared to the other coated samples and the reference samples.
