Description |
Properties of thermal barrier coating (TBC) prepared from 3 wt.% yttria doped zirconia (YDZ) dispersed in a high temperature resistant alumino-borosilicate glassy phase in the system AO-B2O-C2O3-DO2 (where A = Ca, Mg, Ba; B = Na, K; C = Al; and D = Si) have been studied. The resultant coating compositions have been applied with good adherence on stainless steel (AISI-310) by simple and cost effective enameling technique.
The thermal gradient of TBC with coating thickness of about 800 mu m has been found to be within 175-180 degrees C when it was exposed at 1000 degrees C for 30 min. A significant improvement of the gradient to 650-675 degrees C has been observed with a long exposure of coated surface at a temperature of 1000 degrees C aided by a cooling system made of continuous flow of compressed air. Evaluation, characterisation, and microstructure studies have been reported in this paper
