SHS OF COMPOSITE MATERIALS BASED ON TI-CO
Experimental studies for obtaining the porous material on the basis of Ti-Co by self-propagating high temperature synthesis (SHS) followed by welding of the material with the titanium substrate BT1-0 have been carried out. The structure and phase composition of the samples were investigated by scanning electron microscopy and x-ray phase analysis. It is shown that the synthesized alloy Ti-Co has a total porosity of 55–70 % with pore size 200–800 μm. The porous material on the basis of Ti-Co with characteristic pore size of 100–200 µm shows a high open porosity (60 %), uniformly distributed on the sample. Structural characteristics of the materials can be adjusted by changing the synthesis parameters and the initial dimensions of the sample. It is shown that contact zone has no pores or other defects when welding the material on the basis of Ti-Co with titanium substrate VT1-0.
