Abstract
Composite coatings from different volume ratios of hexaferrite (BaFe12O19 or SrFe12O19) and polyethylenewere prepared, for the first time, with flame spraying. The hexaferrite phase retained its crystal structure andmicrostructure during the process, while the polyethylene melted and resolidified. The coatings showedmagnetic hysteresis loops with high coercivities. The measured electromagnetic behaviour proved that thestudied composite coatings would be suitable for electromagnetic wave absorbers in the U-band.
