The vacuum-pumping system is connected with the cavity. The multi-arc target assembly comprises a plurality of cathode multi-arc target seats, a permanent magnet is arranged on each cathode multi-arc target seat, the inner end of each cathode multi-arc target seat is in sealed connection with the cavity through a straight tube magnetic field superposition device, the inner ends of the cathode multi-arc target seats are connected with target material seats sleeved with the straight tube magnetic field superposition devices, the target material seats are used for installing target materials, the cathode multi-arc target seat is provided with an arc introducing device, the arc introducing pins of the arc introducing devices can be in contact with the target materials, and the straight tube magnetic field superposition devices can produce changing magnetic fields in the space where the target materials are located. The multi-arc-ion vacuum coating machine can effectively filter large particles in acoating and make the coating dense and polish and is excellent in performance.

Description

technical field [0001] The invention relates to the technical field of ion coating, in particular to a multi-arc ion vacuum coating machine. Background technique [0002] In the 21st century, machinery manufacturing technology is developing towards high efficiency, high precision, high reliability and specialization; in order to improve efficiency, processing accuracy, reliability and reduce costs, it is necessary to develop ultra-high cutting processing technology, and for ultra- The processing of hard materials and difficult-to-machine materials requires the development of high-performance tools and high-performance hard coatings; and many "green manufacturing technologies" that save energy, protect the environment, and reduce pollution are also inseparable from the development of high-performance tools. The ion coating machine can realize the coating treatment of the tool and the part mold, so that it has excellent performance, significantly improves the surface hardness,...

AI Technical Summary

Problems solved by technology

[0003] Compared with ordinary ion plating coating machines, the multi-arc ion coating deposition rate is fast and the efficiency is high, but there are more large particles in the coating, and the coating is poor in compactness, which affects the performance of tools and workpieces

Especially for some finishing tools and workpieces, the surface of the coating is rough and the friction is high, which directly affects its service life, so the traditional ion coating cannot meet the coating requirements of such products
