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 percentage 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 resistance to the sub layer; it has in fact, an oxidation temperature of 800°C obtaining a superficial hardness of 3,400 Vickers (Hv 0,05). The friction coefficient is 0.45 which enables the use of circular saws with excellent results with limited or minimum lubrication or micro-fog nozzle. It is particularly suitable for high alloy steel, up to 1100 N/mm², for cast iron cutting, stainless steel and all materials that develop high heat energy.
