Gas turbine component coating thickness, hardness or porosity parameter measurement procedure measures time dependence of heat emitted after heating by flash lamp

摘要

A gas turbine component coating thickness, hardness or porosity parameter measurement procedure warms the surface (170) using a laser or flash lamp (120) for preset power and time and measures the emitted radiation (210) using a pyrometer (110), thermal camera or infrared line sensor and calculates (100) the parameter as a function of the time dependence. Independent claims are included for equipment using the procedure.
