Main scientific results

An individual deposition method has been developed on the Bulat-6 spraying unit with different modes. Changes in the main parameters of multilayer composite coatings, such as the thickness of individual layers and the modulation period, can significantly affect the properties and characteristics of the coatings.  The TiZr and TiSi alloy targets with a diameter of 100 mm were used for the deposition. They were arranged in opposite sides of the vacuum chamber since such position prevents substantial intermixing of the metal vapor before arriving at the substrate. Steel substrates were attached to a rotational holder, which was centred perpendicular to the targets at a distance of 200 mm. Before deposition, the chamber was initially evacuated to around 3.0·10^-5 Pa using an oil-vapor pump backed by a rotary pump. Thereafter the chamber was filled with Ar to make the activation of the substrate, and then nitrogen of high purity (99.99%) was injected into the chamber as a reactive gas to deposit nitride films.

Direct result

Multilayer TiSiN/TiZrN composite coatings have been successfully prepared using TiZr and TiSi alloy targets by the cathodic-arc evaporation method. The microstructural analysis revealed the formation of a nanocomposite structure, consisting of TiZrN nanocrystallites with the average size of 9-11 nm. The crystalline Si₃N₄ phase was not identified that suggested the silicon is present in an amorphous phase of silicon nitride or silicon. The SEM observations revealed the multilayer structure with strict chemical composition. Sputtering of argon ions on the substrates before deposition increased the adhesion strength, hence, positively influencing the mechanical parameters. The variation of the hardness of produced coatings ranged from 24.5-38.2GPa with an increase in total layer quantity but decrease in modulation period. Tribological analysis indicated that produced coatings demonstrated adhesive wear.
