Method for applying a plasma sprayed coating using liquid injection

A method for applying a plasma prayed coating using liquid injection is disclosed. The method includes providing a mixture of a liquid and solid particles. The solid particles are constituents of a thermal barrier coating. The mixture is injected into a plasma jet of a plasma spray device and the pl...

Zusammenfassung:	A method for applying a plasma prayed coating using liquid injection is disclosed. The method includes providing a mixture of a liquid and solid particles. The solid particles are constituents of a thermal barrier coating. The mixture is injected into a plasma jet of a plasma spray device and the plasma jet is directed toward a substrate to deposit a gradient film formed from the constituents onto the substrate.
