The Science Behind Diamond Chrome XADC
For industries with particularly high-wear applications, Diamond Chrome XADC provides a superior option to alternative metal surface treatments. Similar to our traditional Armoloy TDC treatment, diamond chrome plating offers a hard and dense, yet thin chromium coating with a micronodular surface texture. The primary difference, however is that the co-deposited nano diamonds allow for increased thermal conduction that provides 20% higher cooling capabilities.
Additionally, with its advanced hardness and wear resistance, Armoloy’s Diamond Chrome XADC works as an application for nearly every common manufacturing steel. You can also expect absolute adhesion that will not chip, peel, or flake from the substrate—as well as increased corrosion resistance.
