ABSTRACT:
Methods for determining corrosion products on a substrate are disclosed. In one embodiment, a non-destructive method for determining an amount of corrosion product on a metallic substrate includes non-destructively determining a value Ia of infrared energy absorbed in a corrosion product on a metallic substrate; and correlating the value Ia of the infrared energy absorbed to an amount of the corrosion product.
