Effect of Cr3C2 distribution on the wear and corrosion properties of HVOF-sprayed WC–12Co/Cr3C2–25NiCr composite coatings

Impact of cyclic thermal shocks on the electrochemical and tribological properties of Fe-based amorphous coating

“…HVOF-sprayed amorphous coatings always demonstrate high amorphous content, low porosity, dense structure, high hardness, and superior adhesion strength to the substrate due to the supersonic velocity of in-flight molten particles and moderate operating temperature [4]. HVOF-sprayed coatings are extensively used in the repairing and surface protection of industrial production components and improve their wear and corrosion resistance and extend their service life [5].…”

“…HVOF-sprayed amorphous coatings always demonstrate high amorphous content, low porosity, dense structure, high hardness, and superior adhesion strength to the substrate due to the supersonic velocity of in-flight molten particles and moderate operating temperature [4]. HVOF-sprayed coatings are extensively used in the repairing and surface protection of industrial production components and improve their wear and corrosion resistance and extend their service life [5].Among various amorphous coatings deposited by the HVOF technique, Fe-based amorphous coatings have significantly attracted researchers and industrialists [6][7][8]. Fe-based amorphous coatings are widely used in marine environments in ships, spent nuclear fuel containers, powder stations, and gas and oil industries [9], attributed to their microdefect-free microstructure without grain boundaries, dislocations or twins along with superior corrosion resistance, excellent wear resistance, high hardness, and low cost [10][11][12][13].…”
