HVOF and plasma spray processes were used to apply Cr3C2-NiCr coatings, which were then characterized by X-ray diffraction and various other tests. The results revealed that the HVOF coatings were more stable than their plasma-sprayed counterparts as well as harder, tougher, less porous, and more erosion resistant. The HVOF coatings have been successfully used in industry and have proven to be an acceptable alternative to electroplated chromium.
