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