Abstract
The kinetics of WSi2 layer growth at the interface of tungsten with molten metals saturated with silicon is studied. Research is performed at 1200 deg rees C using melts based on copper, silver, and tin. It was established tha t WSi2 layer growth in these melts obeys a "parabolic" rule but the corresp onding growth rate constants differ markedly, i.e., from 3.4 . 10(-11) m(2) /sec (melt based on copper) to 1.5 . 10(-13) m(2)/sec (melts based on silve r and tin). The reasons for this difference are discussed.
