Characterization and Corrosion Behavior of Multilayer [TiAlN]n Growth on AISI 316LVM Steel

In this article was characterized and evaluated the corrosion behavior of [TiAlN/]n multilayer coatings with 1, 16 and 32 bilayer periods deposited by the magnetron Sputtering PVD technique on stainless steel AISI 316 LVM. The electrochemical behavior that emulated the corporal environment was evaluated by electrochemical impedance spectroscopy using as electrolyte Hank’s solution. After the degradation test, the characterization was performed by scanning electron microscopy (SEM) and the corrosion products were evaluated using X ray diffraction. It was found a remarkable increase of the corrosion resistance with the deposition of multilayer coatings on substrates, evidencing the effect of increase the bilayers in the decrease of the degradation when increasing the polarization resistance of the multilayer coatings, corroborating the good performance of the bilayers period variation.
