Witryna15 lis 2007 · It has been found that reducing the level of impurity oxides (particularly SiO2 and Al2O3) in 7YSZ, from about 0.2 wt% to below 0.1 wt% raises the sintering resistance and the phase stability of plasma-sprayed coatings. The implications for the usage of these coatings at elevated temperatures are examined. It is concluded that … Witrynaknown as \thermal regelation".

"Witryna21 gru 2024 · The results indicate that the trace impurity has little effect on the GAM without considering toroidal rotation, which is contrary to the non-trace impurity case shown in figure 1 and arising from its small concentration. Therefore, we shall focus on the effect of trace impurity on the GAM in the presence of toroidal rotation. " - Impurity effects in thermal regelation
