ABSTRACT:
The invention concerns the application of a layer of ceramic or glass particles to the surface of a substrate which is to be heated. The glass or ceramic particles are sized and mixed with an organic binder which yields a thin slurry consistency. The carrier or binder hardens. The part is subjected to a running environment with air flow directed across its surface, and then inspected after test to determine flow direction and possibly relative magnitude of the flow. This binder leaves essentially no residue after combustion and holds the glassy particles together so they adhere to the substrate at low temperature. The glass or ceramic particles in the coating are chosen to have a melting point below the operating temperature of the surface so that the applique will flow in the direction of gas movement. Additionally, the choice of melting point is made to give the coating a viscosity which permits enough "smearing" at the velocity and time of interest for visual inspection.
