  7. 20. Characterization of Electrodeposited Fe-based Metallic Coatings: Toward a Sustainable Approach

    Author : Antonio Mulone; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrodeposition; structural characterization; coatings; electrodeposited tin; iron alloys;

    Abstract : Electrodeposition has rapidly grown in the last 50 years and it has been applied to deposit metals and alloys with complex shapes or to produce fully dense nanostructures and amorphous coatings. Thanks to the achieved improved properties of the electrodeposited materials, electrodeposition has been applied in a wide set of applications including protective coatings, and magnetic and electronic applications.
