WebCoatings are typically between 0.001 in and 0.002 in thick. Unlike electroplating, the electroless nickel plate is completely uniform and will enter holes and crevices. The plating is dense and fairly hard at around 43 HRC. Other metals can also be electroless plated but nickel is most commonly used. Chemical Coatings WebCoatings Mode of the Niton XL5 Plus analyzer accurately determines coating thickness of up to 4 layers of pure element or alloy coatings over various substrates made of pure elements, alloys, plastics or wood.3 As a result, the Niton XL5 Plus analyzer can easily measure the coat weight of Ti- and Zr-based conversion coatings over
