Abstract:
An article such as a heat shield panel includes a substrate and a multi-layered coating supported on the substrate. The multi-layered coating can include alternating layers of different ceramic material compositions having individual thicknesses of less than 25 micrometers.
Abstract:
A plasma spraying system is provided for coating a substrate. The plasma spraying system includes a plasma gun, a nozzle and a mounting system. The plasma gun is adapted to direct plasma towards the substrate. The nozzle is adapted to direct coating medium into the plasma. The mounting system is adapted to rotate the nozzle to change an angle of incidence between the coating medium and the plasma.
