Abstract
A method of preventing thermal hydrocarbon degradation deposits on a surface of a gas turbine component, the method includes providing the turbine component comprising the surface configured for contacting a hydrocarbon fluid, wherein the substrate comprises a material having a nominal liquid wettability sufficient to generate, with reference to an oil, a nominal contact angle, disposing a plurality of features on the substrate to form an anti-deposition surface texture, wherein the plurality of features have a size, shape, and orientation selected such that the surface has an effective wettability sufficient to generate, with reference to an oil, an effective contact angle of greater than the nominal contact angle, and the features comprise a width dimension (a), and a spacing dimension (b), wherein the features prevent the hydrocarbon fluid from penetrating into the surface texture and thereby reduce the adhesion of the thermal hydrocarbon deposits to the surface.
