Abstract
A reference standard and method for inspecting dual-layered coatings. The reference standard has a first layer adherent to a substrate, the first layer has a predetermined thickness that increases in one direction. Adherent to the first layer is a second layer, the second layer has a predetermined thickness that increases in a direction orthogonal with the first layer. The orientation of the first and second layers of the reference standard provides a spectrum of the possible variations of the dual-layered coating.
Claims10
A reference standard method for inspection of dual-layered coatings employed for coating a component, comprising:
- a substrate;
- a first layer adherent to said substrate, wherein the first layer has a predetermined thickness that increases in one direction;
- and
- a second layer adherent to said first layer, wherein the second layer has a predetermined thickness that increases in a direction orthogonal with the first layer and wherein at least one of said layers has a predetermined thickness variation and the first and second layers can provide a spectrum of dual coating variances to provide a benchmark for any thickness combination of the dual-layered coatings by using a specific x and y coordinates of the reference standard.
