| Abstract: | Gd2O3-Yb2O3 co-doped nano Gd2O3-Yb2O3-Y2O3-ZrO2 （GYYZO） powder and super fine sprayed powder by co-precipitation and spray dried were prepared. The high temperature phase stability of GYYZO material and coating was enhanced by co-doped than the traditional nano 8YSZ, the trend of porosity, grain size and microhardness of the GYYZO coating under heat treatment 1200℃ of various time was the same, at the begin of heat treatment, the increase and decrease trend was more evidence. |
