Thermal spray deposited environmental barrier coating

Abstract

In one example, a method for forming an environmental barrier coating (EBC) on a substrate. The method may include heating a backside of a substrate using a furnace enclosure, wherein a frontside of the substrate is outside the furnace enclosure, wherein the heating of the backside of the substrate with the furnace enclosure heats the frontside of the substrate to a surface temperature by heat conduction from the backside of the substrate to the frontside of the substrate; and depositing an environmental barrier coating (EBC) on the frontside of the substrate via a thermal spray device while the backside of the substrate is heated using the furnace enclosure, wherein the surface temperature of the frontside of the substrate is selected to control at least one of a porosity of the deposited EBC or a weight percent of a crystalline phase in the deposited EBC.
