9 SURFACE TREATMENTS / SURFACE COATINGS Surface Treatments Bright (uncoated) Bright finish (uncoated surface) improves chip flow in soft or non-ferrous materials and maintains sharp cutting edges inBrightabrasive materials. Steam tempering gives a strongly adhering blue oxide surface that acts to retain cutting fluid and prevent chip to tool welding, Steam Tempering thereby counteracting the formation of a built-up edge. Steam tempering can be applied to any bright tool but is most ST effective on drills and taps. Surface Coatings Titanium Carbon Titanium Carbon Nitride is a ceramic coating applied by PVD coating technology. TiCN is harder than TiN and has a lower Nitride Coating coefficient of friction. Its hardness and toughness in combination with good wear resistance ensures that it finds its principal (TiCN) application in the field of milling to enhance the performance of milling cutters. Titanium Aluminium Nitride is a multi layer ceramic coating applied by PVD coating technology, which exhibits high toughness and oxidation stability. These properties make it ideal for higher speeds and feeds, while at the same time Titanium Aluminium improving tool life. TiAlN is used in drilling, tapping, and milling applications and can be suitable for use when machining Nitride Coatings without coolant. TiAlN-Top coating is the same as TiAlN but with a post-coating process designed to smooth out imperfections, (TiAlN, TiAlN-Top & X-CEED) enhance chip flow and reduce built up edge. X-CEED type TiAlN coating, also known as Futura-Nano coating is a nanolayered coating designed for higher hot hardness and higher stress applications. Aluminium TitaniumNitride Coating(AlTiN) Aluminium Titanium Nitride (AlTiN) is a nanolayered broad based coating technology which is an upgrade to the conventionalTiAlN coatings and can offer superior toughness, high hot hardness and oxidation resistance. Alcrona Coatings(AlCrN, Alcrona, Alcrona-Top & Alcrona-Pro)The Alcrona (AlCrN) family of coatings are aluminium chromium nitride coatings mostly used for milling cutters. The twounique properties of these coatings are high hot hardness and high oxidation resistance. When used on tools for machiningapplications involving heavy mechanical and thermal stresses, these properties translate into superior wear resistance.Multiple levels or specific versions of these coatings are available and specific for various tools and applications. Titanium Silicon TiSiN is designed for extreme cutting conditions and high speed machining of hard materials. This multi-layered coating has Nitride Coating a nano-composite outer layer with Si3N4 nano-crystallites in a crystalline TiN matrix and is engineered to protect the cutting (TiSiN) edge from heat transfer, oxidation and abrasion. TiSiN coatings can perform well at minimum to zero lubrication conditions. 204
