Titanium Nitride (TiN) Coating
Subcategory: Ceramic; Ceramic/Metallic Coating; Nitride
Key Words: Hard Ceramic Coatings; Brycoat; Mold Coating; Aerospace Coatings
Thin film coating applied by environmentally safe, Physical Vapor Deposition (PVD) vacuum system. Can be applied to most metals to provide enhanced surface characteristics, and can also be applied to some ceramics and plastics. Has the appearance of gold, but is an ultra-hard material. Is harder than carbide and chrome, approximately 85 Rc. Is highly inert - Will not corrode and has excellent chemical resistance. Provides a non-stick surface. Prevents galling. Can withstand elevated temperatures. Is non-toxic - Used for surgical devices and food processing equipment. Is dense and non-porous. Is typically 3 micrometers or 0.0001" thick. Has a uniform thickness that follows the contour of the part's surface. Forms an outstanding bond to the base material that will not blister, flake or chip. Cutting tools typically last 3 to 10 times longer than uncoated tools.
