Abstract
A method of treating a component for a gas turbine engine according to an example of the present disclosure includes, among other things, injecting a suspension stream into a plasma gas stream, the suspension stream having coating particles moving in the gas stream toward a component, and placing the coating particles on the component at a coating location to form a top coat that has a columnar microstructure such that a porosity of the columnar microstructure is between 4.0-7.0 percent, exclusive of the intersegment gaps.
