Method of inspecting component surface with marking media
A method of evaluating the quality of a surface on a component comprises the steps of (a) contacting a surface of a component with a media and imprinting qualities of the surface with the media; and (b) evaluating the imprint to determine the quality of the surface of the component.
1. A method of evaluating the quality of a surface on a component comprising the steps of:
(a) contacting a surface of a component with a media and imprinting qualities of the surface with the media to form an imprint;
(b) evaluating the imprint to determine a quality of the surface of the component;
wherein the surface of the component includes a plurality of particles and the evaluation includes determining whether the quality indicates the particles have worn such that they should be replaced; and
wherein said component is a blade for a gas turbine engine and said media is a distinct element from said blade and said plurality of particles.
2. The method as set forth in claim 1 , wherein the media includes a marking paper.
3. The method as set forth in claim 1 , wherein a size of an average imprint is evaluated to determine whether the particles should be replaced.
4. The method as set forth in claim 1 , wherein a percentage of mark per unit area is compared to a limit to identify whether the particles should be replaced.
5. The method as set forth in claim 1 , wherein the particles are abrasive particles on a rotating blade in a gas turbine engine.
6. The method as set forth in claim 1 , wherein an absence of particles is also identified as part of the quality determination.
7. The method as set forth in claim 1 , wherein an imprint from the media on the particles is evaluated to make the quality determination.
8. The method as set forth in claim 1 , wherein a gauge is utilized to ensure a controllable force provides a contact of step (a).
9. The method as set forth in claim 1 , wherein the size of the average quality is evaluated to determine whether the particles should be replaced.
10. The method as set forth in claim 1 , wherein a percentage of mark per unit area of the paper is compared to a limit to identify whether the particles should be replaced.
11. A method of evaluating the quality of a surface on a component comprising the steps of:
(a) contacting a surface of a component with a media and imprinting qualities of the surface with the media to form an imprint, said component being a component in a gas turbine engine;
(b) evaluating the imprint to determine a quality of the surface of the component;
wherein the surface of the component includes a plurality of particles and the evaluation includes determining whether the quality indicates the particles have worn such that they should be replaced;
wherein the media includes a marking paper; and
the marking paper passes qualities from the surface onto a second piece of paper.
12. The method as set forth in claim 11 , wherein a size of an average quality on the second paper is evaluated to determine whether the particles should be replaced.
13. The method as set forth in claim 11 , wherein a percentage of mark on the second piece of paper per unit area of the paper is compared to a limit to identify whether the particles should be replaced.
14. The method as set forth in claim 11 , wherein said component is a blade for the gas turbine engine.
15. The method as set forth in claim 11 , wherein the particles are abrasive particles on a rotating blade in the gas turbine engine.
