| Abstract: | Nanostructured and microstructured WC/12Co coatings were prepared by high velocity oxy-fuel spraying.The properties of hardness,microstructure,adhesion and erosion of two coatings were investigated by comparing with the conventional erosion coatings of axial-flow induced draft fan's blade.The results indicated that the WC/12Co coatings by high velocity oxy-fuel spraying showed better properties than the conventional erosion coatings.Between the two coatings the nanostructured coating showed better properties than the microstructured one. |
