Armor® PVD Chromium Nitride Protective Coating

Armor® is an extremely hard yet ductile Chromium Nitride protective coating (CrN) coating with excellent abrasion, corrosion, and oxidation resistance. The low intrinsic stress properties of Armor® provide excellent adhesion to the substrate under the most demanding conditions and deliver long-lasting resistance to galling and fretting.

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.
