Abstract
The corrosion-protective properties of nanocrystalline TiN coatings (d ∼15–25 nm) with respect to a 12Kh18N10T stainless steel substrate have been studied by the electrochemical method in a 3% NaCl solution. It has been shown that, in the studied thickness range of 1–9 μm, the protective properties of coatings formed by the vacuum-arc method largely depend on the thickness and the factors that affect the level of residual stresses responsible for the presence of defects (porosity) in the coatings. These factors include the deposition rate, the density of the plasma flow onto the substrate, the pulsed negative bias potential amplitude thereon, and reaction-gas pressure.
