THE FIRST NAME IN THIN DENSE CHROME

For over 50 years, Armoloy TDC has been the first name in thin dense chrome. A precision coating effective even at deposits as low as .000050″, Armoloy TDC eliminates the need for secondary machining operations after plating.

For reduced wear, reduced friction, and reduced corrosion across the spectrum of manufacturing applications, Armoloy TDC is the coating of choice for high-precision applications.

Approved by the FDA for food applications and considered safe for food contact by the USDA, Armoloy TDC also complies with REACH, WEEE/RoHS, and meets biocompatibility standards for medical applications.

A very hard (78 Rc) coating with a coefficient of friction as low as .12, Armoloy TDC also provides corrosion resistance equivalent to that of 440C stainless steel.  Excellent wear properties extends part life by up to 5x and significantly reduces downtime when replacing components.  Wear values exceed 1.2 TWI limits established within AMS 2438.

Armoloy TDC is 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. This coating guarantees absolute adhesion to the substrate, leading to extended component life.

For optimal performance, the surface finish of the plated part should be less than 64 RMS and ideally less than 32 RMS.  The better the surface, the better the functionality of the coating for wear and corrosion resistance. Surfaces with finishes under 8 RMS may require a post polish to retain their design requirements.
