Sprayable noble metal coating for high temperature use on ceramic and smoothcoat coated aircraft engine parts

摘要

A method applies a heat-rejection coating directly on a substrate of a ceramic component. The steps include supplying a ceramic component (40), such as of a gas turbine engine, before applying a reflective-coating mixture onto the component (54), wherein the reflective-coating mixture comprises a metallic pigment and a reflective-coating-mixture carrier, and wherein the step of applying is accomplished by a method selected from the group consisting of air-assisted spraying, airless spraying, brushing, and decal transfer. The component having the reflective-coating mixture thereon is fired (56) to form a reflective coating on the component.
