Abstract

A reaction chamber and processing method for PVD film coating, comprising: vacuum extraction, target heating, and film coating. The PVD coating reaction process is carried out in a completely sealed vacuum reaction chamber, and the target is heated by an electron gun to evaporate the target to the surface of the workpiece to form a coating. Using the above PVD reaction chamber, including the reaction chamber body, electron gun crucible table, vacuum pump and product station to be coated, wherein the electron gun crucible table has multiple concave grooves, and different target materials are placed in each groove, which can According to the needs of the explosion-proof film, the concave cavity where the required target material is located is heated separately, the structure is simple, the use is convenient, and the practicability is strong.

Description

technical field [0001] The invention belongs to the field of explosion-proof membranes, and in particular relates to a reaction chamber for PVD coating and a processing method. Background technique [0002] PVD is the abbreviation of Physical Vapor Deposition. It refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target material and ionize the evaporated material and gas, and to use the acceleration of the electric field. The evaporated substance and its reaction product are deposited on the workpiece for vacuum coating. Use physical processes to realize material transfer, and form metal or compound coatings with special properties on the surface of the workpiece. The special properties include high strength, wear resistance, heat dissipation, corrosion resistance, oxidation resistance, and insulation. The substance source of the coating is a solid substance. The target is evaporated or ioniz...
