Coatings for Tools, Tooling, Automotive, Medical Devices & More
Improve the Function & Durability of Critical Components
Chromium Nitride (CrN)
Coating Characteristics: Excellent hardness and toughness, reduced friction, resistant to sliding and impact wear, excellent resistance to corrosion and oxidation, non-stick in contact with many other materials.
Common Applications: Dies and molds, tooling for machining of Cu/Al, engine components, pump parts, and as a replacement for functional plated hard chrome. (See table below for coating specs.)
Diamond-Like Carbon (DLC)
Coating Characteristics: An amorphous carbon coating with very low friction, high hardness, resistant to sliding wear, biocompatible, and an attractive appearance.
Common Applications: Automotive components, medical devices, dies, molds, firearms, cutting tools, sporting goods, and other durable consumer goods. (See table below for coating specs.)
Titanium Nitride (TiN)
Coating Characteristics: Excellent hardness and toughness, biocompatible and non-toxic, reduced friction.
Common Applications: Medical devices and surgical tools, food processing, cutting/punching tools, rotating shank tools, machining of iron alloys, and molds/dies. (See table below for coating specs.)
Zirconium Nitride (ZrN)
Coating Characteristics: Excellent general-purpose coating with high hardness/ toughness, good wear resistance, very good corrosion resistance, biocompatible.
Common Applications: Cutting and punching tools, tooling for machining Al/Ti, medical devices and dental instruments. (See table below for coating specs.)
Zirconium OxyCarbide (ZrOC)
Coating Characteristics: Moderate hardness/ toughness and wear resistance, very good corrosion resistance.
Common Applications: Durable consumer products that require good wear resistance and an attractive graphite or black appearance. (See table below for coating specs.)
