Armor XD® – Enhanced Alloyed Chromium Nitride (CrN) coating

Armor XD® is a uniquely enhanced and incredibly tough Alloyed Chromium Nitride (CrN) coating. Beyond the outstanding abrasion, corrosion, and oxidation resistance found in standard nitride coatings, this advanced variant significantly elevated working temperature threshold, making it ideal for applications demanding superior heat resistance. The innovative alloying process endows Armor XD® with low intrinsic stress properties, ensuring unparalleled adhesion to substrates, even in the most extreme conditions. Its robust nature guarantees extended protection against galling, fretting, and other wear mechanisms, solidifying its position as a top-tier choice for high-temperature and demanding industrial scenarios.

Industrial Hard Carbon a key not only to winning but making your parts last.

Kyle BatesElite Motorsports

Since 2014 Industrial Hard Carbon has supplied all of the Elite Motorsports Team with the best coatings available. The entire IHC team insures we get properly engineered coatings for each project. From engine parts to race car components, IHC delivers!

Joe GibbsJoe Gibbs Racing

IHC is very understanding of our industry and its unique challenges with our supply chain. Carrie and Nickie really get things done for us when we’re under the gun, which seems to be a lot with our suppliers’ late deliveries. IHC makes up lost lead time days with their quick response times.

Stacey StoneKing Engine Bearings

I sell more DLC-coated pins over uncoated ones. It’s inexpensive insurance. I have also seen pins that look brand new after a 500-mile super speedway race.
