The MEVVA source can generate all metal ions from lithium to uranium in the periodic table of elements, the metal ion beam current is strong, the beam spot is large, the MEVVA source is particularly suitable for scientific research and industrial application, and the technical advantages of the MEVVA source comprise: :
(1) strong beam current with 10 milliampere magnitude can be generated for solid metal elements (containing carbon) on the periodic table of the elements;
(2) the ion purity depends on the purity of the cathode material, so that very high purities can be achieved, while expensive and complicated mass analyzers can be omitted;

The mechanism of the film formation process of the metal-doped DLC is: a metal ion arc source (Ti, Zr, Cr and the like) is used as a cathode target material, and a trigger is used for generating a vacuum arc on the surface of the cathode target material under a vacuum environment so that the cathode target material is evaporated and ionized in a discharge chamber (an anode cylinder) to form metal plasma; and under the action of a bending magnetic field, the metal plasma is led out, C2H2 gas is introduced, and the gas is ionized under the excitation of the metal plasma beam to form C plasma. And a certain negative bias is arranged on the substrate, and under the action of the negative bias, the metal plasma and the C plasma carry out a composite reaction on the surface of the substrate to form the metal-doped DLC film.
The composite technology of magnetic filtration cathode vacuum arc deposition and MEVVA source implantation is characterized in that the surface cleaning of a workpiece is realized by using energy-carrying ion beams provided by an MEVVA source, a target film with the thickness less than tens of nanometers is deposited on the surface of the workpiece by the magnetic filtration cathode vacuum arc technology, the workpiece is attacked by using the MEVVA source again, the target film is 'pinned' on the surface of the workpiece, the structural state of the surface of the workpiece is changed, the problem of interface compatibility or bonding force existing between the target film deposited by the subsequent magnetic filtration vacuum arc and the surface of the workpiece is solved, and the high-performance film with high finish, high film density and high film-substrate bonding force is obtained. From the practical application point of view, the technology is more suitable for depositing thick film coating or flexible material surface coating. If the film coated on the surface of the non-conductive flexible material always has the problems of poor film-substrate binding force and easy film falling, the technology can be utilized to metalize the surface of the flexible material to form a film-substrate transition layer, thereby solving the problem of binding force.
The magnetic filtration cathode vacuum arc and MEVVA source composite technology can realize the following functions:
