Formation of intragranular nanocavities in the Cr2O3 layer during the corrosion of Cr3C2+Cr coated Zirlo™
Source abstract
Abstract
Intragranular nanocavities were observed in the Cr 2O 3 layer of a Cr 3C 2+Cr coated Zirlo™ specimen corroded in steam at 1200 ℃ for 1 h. By comparing the coated specimen that was quenched from 1200 ℃ with the one that was not, we considered the root cause of the intragranular nanocavities in Cr 2O 3 was that the nanocavities that formed in the original coating were trapped into the Cr 2O 3 grains during the corrosion process. This explanation may also apply to the formation of intragranular nanocavities in single metal Cr-coated zirconium alloys corroded at high temperatures.
