## Abstract Electroless NiPAl~2~O~3~ composite coatings have been synthesized on mild steel shafts using surfactant cetyltrimethyle ammonium bromide (CTAB) as dispersant. The effects of the surfactant on the alumina dispersion, weight fraction in coatings, and corrosion resistance of the composit
Al 2 O 3 as feedstock were deposited on AZ91D magnesium alloy substrates by cold spray (CS). The content of a-Al 2 O 3 in the feedstock was 25 wt.% and 50 wt.%, respectively. The effects of a-Al 2 O 3 on the porosity, microhardness, adhesion and tensile strength of the coatings were studied. Electro
