The flame temperature of HVOF supersonic flame spraying is more than 3000℃, the spraying speed is about 1400~1700m/s, the spraying flow has protecting effort to spraying powders, so it is very suitable for infusible materials just like WC material, the coating’s quality is better than bomb spraying.
