Microstructures and Properties of Fe/B-Fe Coating Used in Circulating Fluidized Bed Boiler

Abstract:

Electric arc praying technology was used to produce Fe/B-Fe coating on the carbon steel substrate. The microstructures was studied by means of scanning electronic microscope (SEM), X-ray diffraction (XRD), transmission electron microscope (TEM) and electron probe microanalysis (EPMA). Mechanical performances, wear resistance of coating were tested . The results showed that the resistance to abrasion and corrosion of Fe/B-Fe coating was respectively 16 times and 5 to 6 times higher than those of bare metal.
