| Abstract: |
agglomerated and sintered Cr3C2-25%NiCr powders possess excellent flow ability and appearance that have been extensively applied to resist abrase and erosion in high temperature applications such as power boiler. Microstructure of Cr3C2-25%NiCr coatings were observed through scanning electronic microscope (SEM), and bond strength and Microhardness of coatings were measured by tensile shearing test and Vickers hardness test. It is indicated that ultrafine Cr3C2-25%NiCr coatings have some outstanding properties to traditional Cr3C2-25%NiCr coatings by plasma sprayed.
