The structure of intermetallic carbonitrides on the surface of porous biocompatible titanium nickelide obtained by the SHS method
Аннотация
The surface layers and fracture surfaces of porous titanium nickelide obtained by self-propagating high temperature synthesis (SHS) in a flow reactor in an argon atmosphere are studied by SEM and energy dispersive analysis. It is alleged that primary pores 5-15 p in size and the related granular layer are formed due to segregation and capillary force effect during peritectic crystallization of some porous alloy areas. Carbon and oxygen impurities present in the reaction gases and the protective atmosphere penetrate into the melt fdm on the pore surface to form strong and corrosion-resistant nanostructured layers of intermetallic carbides, nitrides and oxides.
