Visible and ultraviolet light absorption of cuo-doped fe alloy coatings prepared by hvof thermal spray technique

Abstract

© 2020, Chiang Mai University. All rights reserved. Fe-based alloy coatings with CuO addition were prepared by HVOF and thermal absorption on visible and ultraviolet light of the prepared coatings was studied. The addition of CuO does not affect the crystal structure and microstructure of Fe-based coatings. The light absorption and the rate of the temperature increase are enhanced, leading to better conversion from photo to the thermal energy of CuO-doped coatings. The result here suggests the alternative property of Fe-based coatings, which may find future application for the visible and ultraviolet light absorber.
