The Science Behind Nodular Thin Dense Chrome
With a hard and dense, yet thin chromium coating, Armoloy Thin Dense Chrome’s micronodular surface texture improves and protects a wide range of high precision metal surfaces without affecting part tolerances. We apply nodular thin dense chrome in a chemical bath through a proprietary process and ensure the chromium metal coating remains effective at deposits as low as .000050″ (1.27 µm).
Our nodular thin dense chrome plating reduces the wear, friction and corrosion of components with a nodular finish—which improves lubrication retention and reduces exposure between surface area to help prevent metal failure.
