The present paper describes recent effort to synthesize Fe-based amorphous alloys coatings using cold gas dynamic spraying (CGDS). Characterization of the gas atomized Fe-based (Fe-Cr-Mo-W-C-Mn-Si-Zr-B) powder shows that the fully amorphous powder is present when particle size diameter in below 20mm. The coating after deposition was composed of the same microstructure as observed in the feedstock powder. The observed overall deformation suggests the occurrence of localized deformation process at the particle/particle boundary and possible adiabatic deformation softening at the powder interior during splat formation. The influence of the substrate material on the coating deposition process was also investigated. The synthesis of fully amorphous, porous free, coatings using CGDS was demonstrated in this work. Moreover, it was also demonstrated that Fe-based metallic amorphous coatings produced by CGDS are strong candidates for wear-resistant and anticorrosion applications.
