The microstructure of a Ni-based self-fluxing alloy coating produced by an oxygen-acetylene flame spraying Ni-16.5Cr-3.3B-4.7Si-4.4Fe-0.8C system alloy powder onto a common steel substrate was investigated by microanalysis methods.The phases in the coating were observed by SEM and determined by XEDS X-Ray energy spectrum and X-Ray diffraction patterns.Meanwhile,some molecular formulas were calculated.
