Thermodynamic Analysis of Chemical Reaction between Components of the Cr - CrB2 - CrSi2 System with Air at Elevated Temperatures
We have carried out a thermodynamic analysis of chemical processes in the Cr - CrB^sub 2^ - CrSi^sub 2^ 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...

| Zusammenfassung: | We have carried out a thermodynamic analysis of chemical processes in the Cr - CrB^sub 2^ - CrSi^sub 2^ 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.[PUBLICATION ABSTRACT] |
