abstract = {Perovskite Ba(Mg1/3Ta2/3)O-3, BMT has promising bulk
properties (thermal conductivity similar to 2 W/m-K and
coefficient of thermal expansion similar to 11 x 10(-6)/K at
1473 K) for thermal barrier coating (TBC) applications at
high temperature. However, during atmospheric plasma
spraying (APS), such material was found to lose constituents
due to the differences of vapor pressures resulting to
non-stoichiometric composition of deposited coatings. To
investigate the extent of phase decomposition at spray
distance and varying electric arc current, different
feedstock powders were plasma sprayed into water and
collected for chemical, microstructural and phase analyses.
When the electric arc current was decreased from 500 A to
300 A, the decomposition of the powders was reduced and the
microstructure of the deposited coatings was improved. The
thermal cycling lifetime of the deposited coatings at
similar to 1250 degrees C surface temperature is also
higher. (C) 2011 Elsevier B.V. All rights reserved.},
