THE FIRST NAME IN THIN DENSE CHROME
Armoloy TDC has been the first name in thin dense chrome for over 60 years. A precision chromium coating effective even at deposits as low as .000050″, Armoloy TDC eliminates the need for secondary machining operations after plating.
Armoloy TDC is the quality coating of choice for high precision applications delivering reduced wear, friction, and corrosion across a broad spectrum of manufacturing applications.
Armoloy TDC is approvable for FDA applications and considered safe for food contact via a blanket approval from the USDA. Armoloy TDC plating also complies with REACH, WEEE/RoHS and meets biocompatibility standards for medical applications.
Armoloy TDC is a very hard (up to 78 Rc) coating with a coefficient of friction as low as .12, which also provides corrosion resistance equivalent to 440C stainless steel. These excellent wear properties can help extend part life by up to 5x and significantly reduces downtime due to component replacement. The Armoloy TDC wear values exceed 1.2 TWI limits established within AMS 2438.
Armoloy TDC metallic coatings are ideal for nearly every industrial steel application, from tool steels such as S-7 and H-13, to bearing steels such as 52100 and 8620, to cold roll, hot roll, high-carbon, and low-carbon steels, to cast iron.
Stainless steel, bronze, copper, and brass are also common substrates requiring additional wear and anti-galling protection. Our coatings’ absolute adhesion will extend component life while providing the added security of knowing that the coating will not de-laminate during use.
For optimal performance in both wear and corrosion applications, the harder and smoother the surface the better. Surfaces with finishes under 8 RMS may require a post polish to retain their design requirements, however, the Armoloy coating is not suitable for mirror finishes.
