Detailed Product Description:

Like Titanium Nitride, Titanium Carbo Nitride won’t chip, peel, or flake.  This is a multiple layer thin film coating providing maximum hardness and toughness.  Due to its increased wear resistance and lubricity, Titanium Carbo Nitride has been used as a substitute for Titanium Nitride in many of the more abrasive wear applications.

It has a beautiful appearance ranging from bright gold to bright polished copper depending upon substrate. It is self-lubricating/non-stick, wear resistant and chemical and corrosion resistant.

Its extreme hardness at 3,000 Vickers (equivalent to about 89 Rockwell C) maximizes its wear resistance.  Empirical data shows improved wear over Titanium Nitride of a factor of seven on cutting tools and a factor of 12 on punching and forming tools.

Titanium Carbo Nitride is applied in a vacuum in a plasma field and forms a metallurgical bond with the substrate.  Inherent in the process is coating thickness uniformity.  No buildup occurs in corners yet the coating throws well into complex geometric features.

Substrate Selection:

PVD coatings are applied to many different materials.  Materials coated include most metals, ceramics, and some plastics.  Substrates must be compatible with a high vacuum environment and must be able to withstand the deposition temperatures of the process. 

The most common materials successfully coated with TiCN are the tool steels, stainless steel, titanium alloys, carbides, Inconel, Hastelloy, the copper alloys and the aluminum alloys.

Avoid metals containing significant amounts of Cadmium (Cd), Tin (Sn) or Lead (Pb) and materials that can outgas in the vacuum chamber. Assemblies and press fit parts can also create an out-gassing situation. 

Substrate Preparation:

Proper adhesion of the coating requires a pristine surface of the part.  The surface must be free of paint, glue, rust, oxidation, etc.  Grit blasting after heat treating and before finish grinding has been found the best approach.  Areas that are not important for coating still must not have a contaminant on the surface that could outgas, as this material will migrate throughout the chamber and contaminate all of the coating.

We clean the parts immediately before coating them.  They should be ready for coating, and cleaned of foreign material, then coated with a light rust-preventive oil for shipment to us.  Parts that do not require oil may be wrapped in a suitable material to prevent contamination and/or prevent oxide buildup.
