Influence of HVOF Thermal Spray Process on the Microstructures and Properties of Fe-Based Amorphous / Nano Metallic Coatings
A new Fe-based amorphous / nano metallic coating with a good combination of high microhardness and excellent erosion corrosion resistance was produced by high velocity oxygen fuel (HVOF). The coating microstructure, amorphous phase content and properties under different HVOF processes were evaluated. It was found that they are very sensitive to the powder feed rate, stand-off distance and oxygen flow. This high performance amorphous / nano metallic coating could be applied as a good alternative material in erosion and corrosion environments.
