Effect of heat treatment on the thermal conductivity of plasma-sprayed thermal barrier coatings

The effect of heat treatment on the thermal conductivity of plasma-sprayed Y sub 2 O sub 3 stabilized ZrO sub 2 (YSZ) and Al sub 2 O sub 3 coatings was investigated. A heat treatment of 1300 deg C in flowing argon for 50 h was found to significantly increase the thermal conductivity of the coatings...
