Abstract:

Monolayer (TiN/Ti) and multilayer films (TiN/Ti; CrN/Ti, TiN/CrN/Ti) with an average thickness of 2300 nm were deposited on SS304 steel using the cathodic arc deposition method. Analysis revealed the presence of numerous macroparticles (peaks) and pinholes (valleys) uniformly distributed across the surface. The monolayer film exhibited superior surface quality compared to the multilayer films but demonstrated poor adhesion to the substrate. X-ray diffraction spectroscopy detected a noticeable shift in the preferred orientation of the deposited film, transitioning from (111) to (200) when employing a multilayer structure. Applying ceramic coatings onto stainless steel induced significant alterations in the potentiodynamic polarization curves of monolayer and multilayer films, resulting in a shift towards more noble potentials and lower corrosion currents than the substrate. Furthermore, the potential passive range expanded when employing multilayer structures based on TiN and CrN.
