Vv. Sobolev et al., INFLUENCE OF THERMAL-PROCESSES ON COATING FORMATION DURING HIGH-VELOCITY OXY-FUEL (HVOF) SPRAYING OF WC-NI POWDER PARTICLES, Surface & coatings technology, 82(1-2), 1996, pp. 121-129
Mathematical simulation of the thermal processes occurring during the
formation of a WC-NI coating on a low alloy steel by high velocity oxy
-fuel(HVOF) spraying was carried out. The factors assessed during the
simulation include the overall temperature changes, the solidification
of the coating, the melting and subsequent solidification of the inte
rface regions of the substrate and the thermal interactions between th
e different layers of the coating. The optimum conditions for the form
ation of good structures in the coating and the adjacent substrate are
estimated.
