THERMAL SPRAY DEPOSITED ENVIRONMENTAL BARRIER COATING
Method for forming an environmental barrier coating (EBC) (68) on a substrate (24) including heating (52) a backside (40) of the substrate (24) using a furnace enclosure (14), wherein a frontside (42) of the substrate (24) is outside the furnace enclosure (14), wherein the heating of the backside (40) of the substrate (24) with the furnace enclosure (14) heats the frontside (42) of the substrate (24) to a surface temperature by heat conduction from the backside (40) of the substrate (24) to the frontside (42) of the substrate (24); and depositing (54) the environmental barrier coating (EBC) (68) on the frontside (42) of the substrate (24) via a thermal spray device (22) while the backside (40) of the substrate (24) is heated using the furnace enclosure (14), wherein the surface temperature of the frontside (42) of the substrate (24) is selected to control at least one of a porosity of the deposited EBC (68) or a weight percent of a crystalline phase in the deposited EBC (68).
