The Armoloy TDC coating will achieve hardness values of up to 78Rc, with results ranging from 72 to 78Rc. Standard hard chrome typically ranges from 68 to 72Rc. The higher rate of hardness is due to the increased density of the coating and lack of a micro-cracked surface. The hardness of the coating is not as applied to the part surface. Due to its incredibly thin nature, hardness readings taken directly on part surfaces measure a combination of the coating and part surface hardness. Coating hardness must be measured on a specially prepared coupon and tested per ASTM E384.

Frequently Asked Questions
Certification to many industry and supplier specifications is available, including AMS 2438 and AMS 2460, depending on the location. In addition, the Armoloy network has fulfillment centers with Quality Management Systems accredited to NADCAP, ISO 9001, and AS9100 requirements.
While thin dense chrome (TDC) and hard chrome are both considered functional coatings, TDC differs from traditional hard chrome in the thickness and surface texture. TDC coatings are in the range of 0.0001 to 0.0005”, while traditional hard chrome is usually over 0.002”, and can measure 0.010” or more, depending on the application. Because of the very low effective thickness, thin dense chrome can often be applied to existing designs without affecting tolerances or fit-up. In addition, traditional hard chrome has a microcracked surface while TDC has a micronodular surface. Both provide a low wear surface, but the micronodular texture can provide superior lubrication retention and wear resistance. Decorative chrome is another coating entirely and is actually a multilayer coating applied to provide an attractive, shiny surface with good corrosion resistance.
Components coated with Armoloy TDC are 100% safe for workers and end users. Plated components are used extensively in the food and drug industry, and routinely certified for REACH and RoHS compliance. In addition, Armoloy invests heavily in the newest technology to help ensure the safety of our employees and communities. For more information, learn about the misconceptions of chromium coatings.
