ARMOLOY ® TDC
Unlike conventional chrome-plating processes, Armoloy ® TDC utilizes proprietary chemical solutions and unique application techniques that are carefully monitored to produce its TDC (Thin Dense Chromium) coating, which follows the exact contours of the basis metal with accurate deposit thicknesses.
Another important aspect of Armoloy TDC is the uniformity of deposit thickness of the coatings, which are typically applied at 1,0 to 17,5 microns (0.000040 to 0.0007 in.). Thinner coatings can be applied with higher degree of uniformity to a component with tight tolerances. The recommended deposit thickness range of 2,5 to 7,5 microns (0.0001 to 0.0003 in.) is uniform within +/- 0,625 microns (0.000025 in.). This allows Armoloy to return a finished product to its customer and eliminates the need for post-coating operations.
Armoloy TDC coatings have been applied to bearings, tools and dies, pumps, plastic and rubber mold tooling, nuclear and aerospace parts, hydraulics, food-processing equipment, and a wide variety of components where wear, abrasion, high friction and corrosive environments are prevalent.
