TITANIUM Nitride (TiN)
TiN has very good corrosion resistance, heat transmission and excellent wear resistance with a wide range of materials including iron based materials, hardened steel, Inconel™, and stainless. It has also been used as a coating on HSS and carbide tools to cut aluminum, some woods, plastics, and fiberglass laminates. Typically, customers see increased tool life by a factor of 5x while running with increased feeds and speeds (finished parts per hour). Longer tool life or greater feeds and speeds depend upon the application, coolant, and other conditions. 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).  TiN helps to prevent premature tool cutting edge chipping and depth of cut notching.

CHARACTERISTICS :
Appearance: Gold
Hardness; 2800 HV.
Coating Thickness; 1-4 microns.
Thermal Stability; 650 deg. C or 1200 deg. F.
Lubricity: 0.55 coefficient of friction

Titanium Carbo-Nitride (TiCN)
As with TiN, feeds and speeds can be increased and tool life can be improved by as much as 800% depending on the application, coolant, and other conditions.  TiCN offers improved wear resistance to abrasive, adhesive, or difficult-to-machine materials such as cast iron, aluminum alloys, steel and 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. TiCN coating has been used with HSS and carbide tools for cutting wood composites, Kevlar™, carbon laminates, fiberglass composites, particle boards, cast iron, super alloys, high silicon content aluminum alloys, better for Inconel™ bakelite, and paper.  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 helps to prevent premature tool cutting edge chipping and depth of cut notching.

CHARACTERISTICS:
Appearance: Grayish Blue
Hardness; 3000 HV.
Coating Thickness; 2-4 microns
Thermal Stability; 400 deg. C or 750 deg. F
Lubricity: 0.2 coefficient of friction

Titanium Aluminum Nitride (TiAIN or AlTiN)
AlTiN offers a higher surface hardness than that of TiAlN, along with different percentages of aluminum and titanium. TiAlN’s improved ductility makes it an excellent choice for interrupted cutting operations. Its superior oxidation resistance provides great performance in high temperature machining. TiAlN does not exhibit edge brittleness and can be used for interrupted cuts without chipping. 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 best for cast iron, aluminum alloys, best for hardened steel and tool steels, best for Inconel™, and nickel alloys.  It has also been used to cut MDF particle board, extending tool life three times over that of an uncoated carbide tool.  TiAlN is best for abrasive wear applications. Also available are multi-layer coatings that chip to the next layer instead of the tooling substrate.

CHARACTERISTICS:
Appearance: Dark Purple
Hardness; 2800 HV.
Coating Thickness; 1-4 microns.
Thermal Stability:  800 deg. C or 1472 deg. F.
Lubricity: 0.5 coefficient of friction

Chromium Nitride (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.

CHARACTERISTICS:
Appearance: Metallic Silver
Thickness: 2-6 microns
Hardness: 2000 Vickers
Thermal Stability: 1300 deg. F or 704 deg. C
Lubricity: 0.3 coefficient of friction

Zirconium Nitride (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.  ZrN coatingcan also be used in cutting wood.

CHARACTERISTICS:
Appearance: Pale Gold
Thickness: 2-5 microns
Hardness: 2800 Vickers
Thermal Stability: 1100 deg. F or 600 deg. C
Lubricity: 0.5 coefficient of friction
