- Abstract
- The interaction of components in the ZrO2-8Y2O3 - VKNA alloy system was studied while simulating operating conditions at 1000-1200 оС in a vacuum atmosphere. Using Raman spectroscopy and electron microscopy, the interaction between some components of the alloy (aluminum, chromium, nickel) and ceramic powder was established, expressed in the destabilization of ZrO2 and the transformation of a part of the tetragonal phase into a monoclinic one.
