The Black Hawk coating applied to a Julia HSS coated circular saw blade is a P.V.D Multilayer coating with depth of 3 micron. The plasma is obtained by the fusion of a titanium cathode and aluminium, in a particular composition. The addition of an inert gas during the process, and the energy source with which the molecules are loaded, enable surface bombardment of the coating, resulting in excellent coating properties that guarantee a high thermal bond to the sub layer at an oxidation temperature of 800°C obtaining a surface hardness of 3,400 Vickers (Hv 0,05). The friction coefficient is 0.45 which enables the use of these blades with limited or minimum lubrication or mist coolant. It is particularly suitable for high alloy steel, up to 1100 N/mm², for cast iron cutting, stainless steel and all materials that generate high heat during cutting.

Coatings are carefully designed for each specific cutting application, our surface coating department is equipped with the machines that use the very latest technology in the field of Physical Vapour Deposition enabling us to deposit a higher number of molecules per surface unit thus greatly improving both the adherence and wearing resistance of the coating. These coatings are unique and are the result of continuous research into mechanics and materials with universities and practical collaboration on applications with leading machine manufacturers and their users. These partners in particular, have allowed Julia to coat their own circular saw blades with surfaces made of nanotapes consisting of noble chemical components (titanium, aluminium, Chromium, Zirconium) whose unique composition our company is very proud of. The close cooperation between our technical department and research centres, machine manufacturers and end users enables our engineers to recommend for each specific application the blade and coating which provides the highest performance in terms of speed, feed rate and durability, all of which guarantee the lowest possible cutting cost.
