Microstructural evolution of carbides and its effect on tribological properties of SAPS or HVOF sprayed NiCr–Cr3C2 coatings

The wear resistance of NiCr–Cr3C2 cermet coatings is highly dependent on the feature of carbides. In the present work, NiCr–Cr3C2 coatings were deposited by two typical high-velocity spraying methods including supersonic atmospheric plasma spraying (SAPS) and high velocity oxygen-fuel (HVOF) sprayin...
