Abstract: | The kinetics of WS2 layer growth at the interface of tungsten with molten metals saturated with silicon is studied. Research is performed at 1200°C using melts based on copper, silver, and tin. It was established that WSi2 layer growth in these melts obeys a “parabolic” rule but the corresponding growth rate constants differ markedly, i.e., from 3.4·10?11 m2/sec (melt based on copper) to 1.5·10?13 m2/sec (melts based on silver and tin). The reasons for this difference are discussed. |
