Abstract:Ti-Fe-Cr-Ni-C composite coatings were deposited with a new process of Reactive Flame Spray (RFS) from the powders synthesized by the process of precursor-carbonization-composite, in which ferrotitanium and asphalt were used as raw materials. XRD and SEM were employed to analyze the phase composition and microstructure of the composite powders and coatings. The wear resistance of the coating was tested. The results show that the TiC/FeCrNi composite coating by RFS is composed of layers in which the round nanoscale TiC particles are dispersed within a metal matrix. The matrix consists of Cr0.19Fe0.7Ni0.11 and (Fe, Cr). Under the same condition of wear testing, the wear volume of the TiC/FeCrNi composite coating is one eighth of that of the Ni60 coating by normal flame spray.
