“…The mechanism causing such fractures is due to the microshock effect of cavitation bubbles, which leads to pressure on the surface areas of the sample and its vibration and deformation [16,17]. It should be noted that in the multilayer structure there is a softer metal sublayer under the hard molybdenum nitride coating.…”

A complex modification of 25CrMoV steel has been carried out, which includes nitriding in arc-enhanced glow discharge plasma, deposition of metallic sublayer (Mo, Cr or Ti) and deposition of top layer of Mo2N coating. The structure studies showed that depending on the material and the thickness of the sublayer (1.5...6 µm), defects and delaminations could form at the interfaces, while no defects were observed in the absence of the metallic sublayer. The concentration of nitrogen in the complex modified layers depends on the composition of the metallic sublayer, but does not affect the total depth of nitriding of the hardened steel ~ 160 µm. The hardness of the nitrided layer is ~ 12 GPa, and the hardness of the Mo2N coating is ~ 30 GPa. The cavitation resistance of complex-modified 25CrMoV steel without the metal sublayer is 2 times higher than the initial steel.

This review presents an examination of various studies investigating the impact of deposition process conditions and structural characteristics of TiN-based vacuum-arc coatings on their ability to withstand cavitation erosion in water. The structural and phase composition of TiN coatings is influenced by two key technological parameters: the nitrogen pressure in the vacuum chamber and the substrate bias potential. However, it has been observed that vacuum-arc alloy coatings such as TiSiN and TiAlYN exhibit notably lower resistance to cavitation erosion. Additionally, research on multilayer Ti-TiN coatings with varying numbers and thickness ratios of layers has not shown an improvement in resistance to cavitation wear when compared to single-layer coatings deposited under optimal conditions. On the other hand, single-phase stoichiometric TiN coatings deposited at a higher nitrogen pressure of 2 Pa and a bias potential of up to -300 V have demonstrated remarkable resistance to cavitation wear. These coatings could be effectively utilized to protect the titanium alloy Ti-6Al-4V against cavitation damage.
