ABSTRACT:
The present invention provides a sprayable composition comprising a ceramic particulate including albite, illite, and quart, and a metallic composition, including nickel, chromium, iron, and silicon. The sprayable composition may be a composite particle, a blend, or a cored wire. The present invention further provides an abradable coating formed on a metal substrate according to a method comprising the step of depositing the abradable coating on the metal substrate by thermal spraying of a sprayable composition comprising a ceramic particulate including albite, illite, and quartz, and a metallic composition, including nickel, chromium, iron and silicon. The sprayable composition may be a composite particle, a blend, or a cored wire. The abradable coating may be applied to a metal substrate such as steel, nickel-based alloys, and titanium.
