Electrochemical Noise Behavior of YSZ Coatings Applied by Magnetron Sputtering on Aircraft Alloys 2015-01-2605

Thin films deposited by magnetron sputtering are review in terms of their potential and present uses in the aircraft industry. The aircraft alloys substrates were Ti-6Al-4V and Incoloy 800HT, using a target of yttrium stabilized zirconia (YSZ) with nominal composition of 8% Y2O3 (wt%) and the remainder of ZrO2. The chemical composition of the films was determined by X-ray energy dispersion (EDS). The electrochemical noise behavior show that the coatings decreased propagation of pitting, leading to a state of passivation or uniform corrosion, and also possess superior corrosion resistance over the individually substrates.
