Abstract
A method and coating system are provided that use a temperature controlled gas flow to smooth a surface of a ceramic, like a thermal barrier coating (TBC). Thermal spray coating unit coats a ceramic on a surface. The thermal spray coating unit creates a flow of ceramic material towards the surface. A layer of at least partially molten ceramic material on the surface is smoothed by transmitting a flow of temperature controlled gas across the at least partially molten ceramic material on the surface after the thermal spray coating of the ceramic on the surface. The solidified ceramic has a smoother surface that requires much less polishing to attain a desired surface roughness.
