Tungsten Carbide Cutting Tool Coating Method - Ion Plating

Ion plating is a tungsten carbide cutting tool under vacuum, or using gas discharge portion ionized vaporized material, the material in the gas ions or ion bombardment of the evaporator while the evaporation substance or a reactant is deposited on the tungsten carbide substrate . It combines fast evaporation deposition plating and sputtering ion bombardment cleaning surface characteristics, especially with a film adhesion, good diffraction properties of a wide range of materials and plating, etc., so this technique to obtain a rapid development of. Coated tungsten carbide cutting tools most basic features of a neutral particle generating ions are ionized by the action of a particular method, and by the negative bias applied on the substrate, so that the generated ions to the substrate and the coating layer have a sustained bombardment, and achieve the coating deposited on the substrate purpose, generally the better the efficiency of ionization.

Tungsten carbide cutting tool ion plating techniques include: Reactivity evaporation ion plating, hollow cathode ion plating, arc ion plating. And several of the arc ion plating technology, with its high rate of metal ions, help to improve film adhesion and film-based performance; deposition rate, high plating efficiency, simple structure, low voltage, safer, become the most successful and most widely used ion plating.
