Influence of heat treatment on morphology and phase composition of TEG-Co composite material
The influence of ageing and heat treatment on the structure, phase composition and morphology of cobalt supported composite material TEG + 30 mass.% Co prepared by chemical deposition method has been studied using the X-ray diffraction, scanning elec -tron microscopy, the Auger spectroscopy and SIMS...

Heat treatment of the studied materials results in phase transformations within the metal component consisting in the formation of complex cobalt oxide and cobalt carbide phases. After heat treatment the shape of modifier particles remains similar to that in as-prepared composite material whereas their size drastically increases that may evidence the recrystallization processes accompanie d by the metal-modifier particle segregation. |
