The solution jf tungsten in the Fe-Cu,Co-Cu and Co-Sn,Fe-Sn Melts and molybdenum, in the Si-Cu melt has been investigated at 1200 C .The layr growth of binary compoundsW6Fe7,W6 Co7 , Mo5Si3 и MoSi2 was studied idifferent ternary diffusionsystems which were prepared by immesion of tungsten and molybdenum samples in different two-component melts containing Si (Fe,Cu) and a metal.The dependence of the constant of intermtdiate phase layer growth on tungsten and molybdenum samles on the activity of silicon ( or iron,cobalt ) in the melt was establisyed.When the silicon ( or iron,cobalt ) content in the melt was loweer than that at the three-phase equilibrium,no intermediate phse growth was observed.Withits increasing,the rate of tye layergrowthrises.The latter also dependson the basic melt metal and may differ within an order of magnitude , which is due to admixture of the metal into the layer.The obtaintd results in view of determination of optimal parameters(temperature,process time,concentration of active in melt ) for depositijn of protective layers.
