Abstract
A non-destructive method is provided for determining the amount of an anodize coating on a metallic substrate. A value of infrared energy reflected from the metallic substrate without the anodize coating is determined. A value of infrared energy reflected from the metallic substrate with the anodize coating is determined. A value of infrared energy absorbed in the anodize coating is determined, and the value of the infrared energy absorbed in the anodize coating is correlated to an amount of the anodize coating.
