Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="pssa201200742-sec-0001" sec-type="section"> <p>Mg–Zn thin film alloys were produced by thermal co‐evaporation using single source and dual source geometries. The films containing high amount of Zn (66 at.%) were prone to formation of metallic micro spheres on the surface when high evaporation rates (10 nm s⁻¹) were used. The Mg–27.1 at.% Zn bulk alloy was found to be suitable for co‐deposition with Al for producing Al–Mg–Zn thin film alloys. A low Al concentration gradient (5 at.%) could be obtained along the sample due to the high deposition rates of Mg–Zn (7.5 nm s⁻¹) combined with low Al deposition rates (0.2 nm s⁻¹). The Al–Mg–Zn thin films showed an improved resistance against chemical attack when higher amounts of Al are used, as shown by downstream analytics investigations using a flat flow electrochemical cell coupled to an AAS system. <inline-graphic xlink:href="ark:/27927/pgg20q11xcb" content-type="pssa201200742-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
