A novel method of depositing grit particles onto a fan blade tip coating is provided. The method enhances grit capture by presenting a softened coating surface for the impinging particles. The softened surface is achieved without high substrate temperatures that could degrade the base metal properties in the fan blade. An auxiliary heat source is used to establish a locally heated and softened surface where the grit deposition takes place. The softened surface greatly increases the probability of grit capture.

The invention relates to a method for adhesion of a thin film or functional layer to a substrate by applying a pulsed and/or alternating voltage.

A method of fusing an alloy-based material with a coating layer using a thermal spray process. The method includes determining a predetermined energization frequency of a high-frequency power supply unit based on a diffused area thickness (T1) and a non-diffused area thickness (T2) of the alloy-based material, inductively heating the alloy-based material and the coating layer to reach a predetermined temperature at the predetermined energization frequency of the high-frequency power supply unit, selectively heating the alloy-based material at the predetermined energization frequency within a penetration depth range of a total thickness (D2) of the alloy-based material to suppress an austenite transformation of at least a portion of the alloy-based material, and fusing the selectively heated alloy-based material with the coating layer by suppressing the austenite transformation of at least the portion of the alloy-based material.

A lift-off structure for a sprayed thin layer on a substrate surface and a method for the same are provided. The lift-off structure for the sprayed thin layer on the substrate surface includes a base layer and a lifted-off sprayed thin layer. The lifted-off sprayed thin layer is formed on the base layer.

A coated member includes a bond coat and a top coat sequentially laminated on a substrate made of a Si-based ceramic or a SiC fiber-reinforced SiC matrix composite, wherein the top coat includes a layer composed of a mixed phase of a (Y.sub.1-aLn.sub.1a).sub.2Si.sub.2O.sub.7 solid solution (here, Ln.sub.1 is any one of Nd, Sm, Eu, and Gd) and Y.sub.2SiO.sub.5 or a (Y.sub.1-bLn.sub.1′b).sub.2SiO.sub.5 solid solution (here, Ln.sub.1′ is any one of Nd, Sm, Eu, and Gd), or a mixed phase of a (Y.sub.1-cLn.sub.2c).sub.2Si.sub.2O.sub.7 solid solution (here, Ln.sub.2 is any one of Sc, Yb, and Lu) and Y.sub.2SiO.sub.5 or a (Y.sub.1-dLn.sub.2′d).sub.2SiO.sub.5 solid solution (here, Ln.sub.2′ is any one of Sc, Yb, and Lu).

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.
