The method of anodic evaporation of aluminum in an arc discharge of low pressure in an oxygen-argon medium and deposition on an isostructured sublayer under conditions of intensive ion support was used to obtain a nanocrystalline coating of aluminum oxide with a corundum structure and to determine the range of changes in the parameters of the ion flow to the surface of the growing coating, which provides the formation of a dense solid (25 GPa) coating with a low level of internal stresses at a speed of up to 4 µm/h at a temperature of 600°C.
