Abstract
“Titanium carbide – a high speed steel (HSS) steel binder” metal matrix composites were synthesized by the wave combustion mode and investigated. Composite powders “TiC + HSS” obtained by crashing of the self-propagating high temperature synthesis (SHS) cakes were used for electron-beam surfacing of the coatings. An microstructure evolution of composite powder granules during of the surfacing is traced. The evolution involves a partial dissolution of the composite granules in the melt of the surfacing bath and subsequent crystallization of dispersed carbide particles in the dendrites form from a liquid metal solution containing titanium and carbon. The microstructure of the deposited coatings correlates with their hardness and abrasive wear resistance. The abrasive wear mechanism of the coatings is discussed.
