Abstract
The heterodiffusion has been studied by the method of stationary diffusion source. In that method the saturated radioactive vapour of the diffusing element comes into contact with the liquid in which diffusion is being studied. Two variants of that method were applied and the diffusion coefficients of chromium and cobalt in liquid iron were determined, i.e.D (Cr→Fe, 1860K)= =4·9×10−5cm2/s andD (Co→Fe, 1820K)=5×10−5cm2/s, respectively. The values of maximum concentration of chromium in Fe-samples after diffusion were of the order of 10−1 to 10−2 wt-%, those of cobalt of 10−4 wt-%. This experimental method is rather simple and the results obtained are in good conformity with other measurements.
