Titanium Nitride (TiN)
This high performance coating is a great all-purpose choice for increasing tool life. TiN increases hardness and has a high oxidation temperature. This coating is bright gold in color with a surface hardness reaching 81 Rc and a .4 coefficient of friction. Titanium Nitride (TiN) is the most common PVD hard coating in use today. TiN has an excellent combination of performance properties, attractive appearance, and safety (meets FDA requirements for surgical tools and implants as well as food contact applications). Hardness; 2800 HV. Coating Thickness; 2-4 microns. Thermal Stability; 550 deg. C or 1000 deg. F.
Titanium Carbo-Nitride (TiCN)
TiCN offers improved wear resistance to abrasive, adhesive, or difficult-to-machine materials such as, cast iron, aluminum alloys, tool steels, copper, inconel and titanium alloys.This multi-layered coating is best suited for hard work materials over 40 Rc and operations involving interrupted cuts and high shock applications. The addition of carbon adds more hardness and better surface lubricity. Coating is medium gray or bronze in color with hardness reaching 90 Rc and a .3 coefficient of friction. TiCN Coating has up to 750 Degree F thermal stability. Hardness; 3000 HV. Coating Thickness; 2-4 microns. Thermal Stability; 400 deg. C or750 deg. F.
Titanium Aluminum Nitride (TiAlN or AlTiN)
This popular coating is recommended for applications where heat resistance and extra hardness is required for abrasive materials.A formed layer of aluminum oxide gives this tool better life in high heat applications. This coating is primarily selected for carbide tooling where little to no coolant is being used. Coating is purple/black in color with a surface hardness in the upper 80 Rc range with a coefficient of friction less than Titanium Nitride (TiN). TiAlN coating is a high performance coating which excels at machining of abrasive and difficult-to-machine materials such as cast iron, aluminum alloys, tool steels, and nickel alloys.
CrN
Chromium Nitride is a special coating developed to endure conditions under high loads, and its low residual stress enables it to have the greatest adhesion and ductility of all PVD coatings. These properties provide CrN with a niche for forming and drawing applications where optimum release is needed. Also, CrN can be beneficial on wear components, due to its excellent surface adhesion which creates a tough resistance against corrosion. Recommended applications are Carbon Steels, Aluminum, Aluminized or Zinc Coated Steels, Brass, Copper and 300 Series Stainless Steels.
Appearance: Metal-Silver
Thickness: 2-6 microns
Hardness: 2000 Vickers
Thermal Stability: 1300 deg. F or 704 deg. C
Lubricity: 0.5 coefficient of friction
ZrN
Zirconium Nitride is a special coating developed to perform in areas that TiN has proven unsuccessful. ZrN possesses a very low deposition temperature, which makes it most suitable for temperature-sensitive substrates. Also, ZrN has an excellent corrosion- resistance, lubricity and hardness to suit many applications. A coating that works well with non-ferrous materials, ZrN has a unique ability to reduce the build-up edge on cutting tools and leave a better surface finish on materials its machined. ZrN is appropriate for machining Titanium and Aluminum Alloys, Nickel, Brass, Copper, Cast Iron and Zinc.
Appearance: Pale Gold
Thickness: 2-5 microns
Hardness: 2800 Vickers
Thermal Stability: 1050 deg. F or 565 deg. C
Lubricity: 0.5 coefficient of friction
