Abstract
We have carried out a thermodynamic analysis of chemical processes in the Cr – CrB2 – CrSi2 system at 1400 K to 1800 K. We have established that chromium diboride fulfills the function of a protective layer, while chromium disilicide protects against reaction with air at temperatures up to 1473 K.
