摘要
The morphology of the SiC/Ti reaction zone has been analysed by scanning electron microscopy. The composition of the different constituents was determined by Auger and X-ray microprobes. It was found that the two main constituents through the reaction zone were Ti5Si3(C) and TiCx. The TiCx crystals were measured from the inner part of the reaction zone (against the SiC) to the outer part of the reaction zone (against the titanium). By changing the scale of space by the scale of time, it has been possible to get the age of the TiCx crystals. This new approach has been useful to determine the kinetic rate of the SiC/Ti reaction and also to understand what was the driving force for the SiC/Ti reaction zone growth.
