“…Another work presented the thermal evaporation technique-based deposition of MoO 3−x thin films of differing thicknesses such as 100, 200, 300, 500 and 650 nm with improved corrosion resistance [55]. Thermally evaporated Cu and Ag on NiTinol shape memory alloy were studied for their corrosion inhibition capability for biomaterial applications [56]. In the present work, thermal evaporation is used, similar to e-beam evaporation.…”

Al coating of varying thicknesses in the 50 to 200 nm range was coated on AZ31 Mg alloys to improve its corrosion capabilities. The thermal evaporation method is used for coating AZ31 Mg alloys. GIXRD, SEM, AFM and XEDS studied the structure, microstructure, and chemical analysis. GIXRD studies showed an amorphous thin film on the surface. AFM showed that the surface roughness increases with the coating thickness. Corrosion studies were done by electrochemical analysis in 3.5 wt-% NaCl environment. The Al coating has improved the corrosion resistance of the AZ31 alloy to the best with the lowest corrosion rate 0.07 mmpy, with the corrosion current density and corrosion potential of 0.32 × 10−5 A/cm2 and −1.17 V, respectively.
