Abstract
A thermoelectric potential probe inspects the surface coating thickness of a turbine bucket blade using a rolling ball probe head to traverse the surface of the bucket. The probe may be hand-held or affixed to a computer controlled robotics coordinate measuring machine. The rolling ball head has embedded heating elements and is a thermal-electric sensor that gathers data regarding the thickness of coating on a turbine surface.
