Black Titanium Nitride (TiN) – RCT-1 Raven Spear Point Dual Serrated
440C Stainless Steel
Titanium nitride (TiN) coating is wear resistant, inert and reduces friction. Use it on cutting tools, punches, dies and injection mold components to improve tool life two to ten times, or more, over uncoated tools.
Medical device manufacturers use TiN coating to reduce galling between sliding components, help retain sharp edges on surgical instruments, and differentiate their products from the competition.
Provides 2 – 10 x the tool life vs. uncoated tools.
Biocompatible, used on many medical instruments and implantable devices.
Easily stripped from tool steels.
Thickness: .0001″ – .0002″
Hardness: 2400 – 2600 Hv
Deposition Temp. 700 – 800°F
Titanium nitride (TiN) (sometimes known as tinite) is an extremely hard ceramic material, often used as a coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate’s surface properties.
A well-known use for TiN coating is for edge retention and corrosion resistance on machine tooling, such as drill bits and milling cutters, often improving their lifetime by a factor of three or more.
As a coating it is used in aerospace and military applications and to protect the sliding surfaces of suspension forks of bicycles and motorcycles as well as the shock shafts of radio controlled cars. TiN is non-toxic, meets FDA guidelines and has seen use in medical devices such as scalpel blades and orthopedic bone saw blades where sharpness and edge retention are important. TiN coatings have also been used in implanted prostheses (especially hip replacement implants) and other medical implants.
Due to their high biostability, TiN layers may also be used as electrodes in bioelectronic applications  like in intelligent implants or in-vivo biosensors that have to withstand the severe corrosion caused by the body fluid. TiN electrodes have already been applied in the subretinal prosthesis project  as well as in biomedical microelectromechanical systems (BioMEMS).
TiN is an extremely hard ceramic material, often used as a coating on titanium alloys, tool steel, stainless steel, carbon steel and other metallic components to improve the substrate’s surface properties. Common applications include aerospace parts, military components, medical implants, cutting tools, industrial parts, manufacturing dies / molds and dental and orthodontic appliances.
Benefits of TiN coating:
Hard, scratch and wear resistant
Lubricious, corrosion and chemical resistant
No appreciable build-up to interfere with firearm operation
Can be applied to just about any metal surface
