Many people don't know much about multi-arc ion vacuum coating machines, let alone how the technology of coating equipment is applied to the tool industry, including how to resist oxidation. Many customers have such doubts and often ask us about this. Especially for fans of vacuum equipment, today Huicheng Vacuum Xiaobian will explain in detail how the anti-oxidation method and process of multi-arc ion vacuum coating machine are applied to the tool industry.

In order to meet the requirements of coating system and various multilayer films and composite compound films, multi-functional multi-arc ion plating has become the current research and development direction. The multi-arc ion coating equipment adopts the method of arc discharge to directly evaporate the metal on the solid cathode target, and the evaporated material is the ions of the cathode material released from the bright spot of the cathode arc, so as to deposit a thin film on the surface of the substrate. The multi-arc ion coating adopts the advanced technology of twin targets, which overcomes the inherent disadvantages of DC sputtering, such as target poisoning and ignition, and improves the oxidation and corrosion resistance of the plated parts. The center of the multi-arc ion coating is to install a cylindrical multi-arc target, and the target material is titanium or zirconium. It can not only maintain the characteristics of high ionization rate and high deposition rate of multi-arc technology, but also effectively reduce the defects of "droplets" that are difficult to avoid during the deposition of facet multi-arc targets, so that low porosity can be prepared. Metal thin film or compound special thin film; twin planar magnetron targets are installed around the periphery, and the target material is aluminum or silicon; at home and abroad, multiple facet multi-arc evaporation sources are installed around the periphery, and the target material is chromium or nickel, which can be plated with multiple layers Metal films and multilayer composite films. The composite ion coating equipment has a variety of different types of coating devices and evaporation sources and emission targets of different materials. They can work independently and simultaneously, and can prepare both pure metal films and metal compound films or composite materials. Film; it can prepare both single-layer film and multi-layer composite film, and has a wide range of uses.
        In some special application fields of modern times, sometimes a single coating technology cannot meet the special needs of the workpiece in the factory, such as cutting tools. To improve the performance of the product, it is necessary to use a variety of technologies. Now many tool companies use the most multi-arc ion coating equipment and infiltration composite process coating equipment. When no new process is developed, the commonly used process of enterprises is: infiltration and plating composite process, which includes ion nitriding, ion plating and so on. Infiltration plating composite process and multi-arc ion coating, infiltration composite process, etc. The workpiece should be ion nitrided before coating, which can not only strengthen the deformation ability of the film, but also because there is a relatively smooth transition zone under the film, the stress distribution from the film to the substrate can be better, so compared with no For workpieces using the nitriding process, the mechanical resistance of the coating is improved. Through the multi-arc ion coating technology, a hard film of metal or its alloy can be deposited on the surface of the tool, which is also the most common way to improve its life. It is very limited to increase the life of the tool by increasing the hardness. We should consider synthesizing a layer of MoS2 solid lubricating film on the surface of the hard molybdenum plated in situ to further improve the tool life.
life.
         After reading the above content, it should be understood now that the application method of multi-arc ion vacuum coating machine in the tool industry is actually not only used in the tool industry, but also widely used in other industries. Opportunity to introduce to you one by one.
