System and method for measuring cooling of a component

A method for measuring cooling effectiveness, the method comprising:

• providing the component having a surface provided with a coating including a volatilization-susceptible constituent and a volatilization-resistant constituent;
• supplying a first gaseous medium from a first source, through a plurality of holes in the component for a predetermined period, for forming a cooling film of the first gaseous medium on the surface;
• feeding a second gaseous medium from a second source, along the surface of the component for the predetermined period and volatize at least a portion of the coating upon exposure to the second gaseous medium to form a removed portion of the coating;
• determining a thickness of the coating exposed to a flow of the first and second gaseous mediums for the predetermined period;
• and
• analyzing the thickness of the coating for a removed thickness of the coating that is indicative of an ineffectively film cooled region on the surface of the component and for a retained thickness of the coating that is indicative of an effectively film cooled region on the surface of the component.

A system comprising:

• a first source for supplying a first gaseous medium through a plurality of holes in a component, said component having a surface provided with a coating including a volatilization-susceptible constituent and a volatilization-resistant constituent;
• a second source for supplying a second gaseous medium along the surface of the component;
• a measurement device for determining a thickness of the coating exposed to the first and second gaseous mediums for a predetermined period;
• and
• a processor-based device communicatively coupled to the measurement device, wherein the processor-based device is configured to:
• receive the thickness from the measurement device;
• and
• analyze the obtained thickness to determine whether at least a portion of the coating is removed from the surface of the component upon exposure to the first and second gaseous mediums, wherein a removed thickness of the coating is indicative of an ineffectively film cooled region on the surface of the component and a retained thickness of the coating is indicative of an effectively film cooled region on the surface of the component.
