Vacuum coating is a large branch of vacuum application, which is widely used in optics, electronics, physical and chemical instruments, packaging, mechanical and surface treatment technology. In order to make you more detailed understanding of the application of vacuum coating, today small series for you to introduce the vacuum coating application of the main methods, I hope you are useful! The application of vacuum coating is simply understood as the use of evaporation, sputtering and subsequent condensation in a vacuum environment, a metal film or coating on metal, glass, ceramics, semiconductors, and plastic parts. Compared with traditional coating methods, vacuum coating is a kind of dry coating. Its main methods include the following: Vacuum evaporation The principle is that under vacuum condition, the evaporator is used to heat the evaporated material, which is vaporized or sublimated, and the evaporated ion stream is directly shot to the substrate, and the solid film is deposited on the substrate. Sputtering coating The sputtering coating is a vacuum process in which a high voltage of 2000V is applied to the cathode, triggering a glow discharge in which a positively charged argon ion strikes the cathode, causing it to eject atoms, the sputtering atoms are deposited on the substrate in an inert atmosphere to form a film layer. Ion plating Dry screw vacuum pump manufacturers have already introduced the vacuum ion coating. It is developed on the basis of the above two vacuum coating technologies, so it has both of the process characteristics. Under vacuum condition, working gas or evaporated material (membrane material) is partially separated by gas discharge, and evaporates or its reactants are deposited on the substrate surface by ion bombardment. In the process of film formation, the substrate is always bombarded by high-energy particles, very clean. Vacuum winding coating Vacuum winding coating is a kind of continuous coating technology on a flexible substrate using a Physical vapor deposition method to realize some functional and decorative properties of the flexible substrate. These are all Physical vapor deposition applications (PVD) . Then there's Chemical vapor deposition. The principle is that the reaction gas containing the film-making material is passed to the substrate at a certain temperature and is adsorbed to produce a chemical reaction on the substrate to form a nucleus, the reaction product then diffused away from the substrate surface to form a film. Beam deposition, combined with ion implantation and vapor deposition, is a kind of ion surface treatment technology, which uses ionized particles as evaporation material, and at lower substrate temperature, technology for forming thin films with good properties.

PVD coating processing process is relatively long, the process of a variety of fault factors will be many. Such as PVD coating pretreatment is not clean, poor cleaning, electrolyte composition imbalance and impurities pollution, poor production environment. PVD coating and failure reasons often exist in the above factors of one or two details. PVD coating processing PVD coating process in the impact of product quality of the five factors (operators, equipment, materials, technology and production environment) , people are the first. PVD coating failure is related to the operator's professional skills and work responsibility. PVD coating production managers on operator guidance and supervision, these are more common in PVD coating enterprises, PVD coating makes failure inevitable. It is very important to improve the professional skills and work responsibility of PVD coating workers in order to reduce the production failure of PVD coating. The production failure of PVD coating process is a problem that every PVD coating enterprise will encounter. Troubleshooting is an important responsibility of PVD coating technicians. PVD coating practice to know, PVD coating production practice is very strong. In order to control the whole process of PVD coating production, the only way to PVD coating is in the production practice, tough and good at thinking, continuous exploration and accumulation.

Ion plating, also known as“IP plating”, is the technology with the highest density, the highest hardness and the best durability in PVD vacuum plating. It is a combination of vacuum evaporation and sputtering, first by sputtering to thoroughly clean the surface of the plated parts, and then mixed heating metal vacuum evaporation and sputtering to be coated parts, that is the so-called ion plating. Ion-plated coating can be extremely tightly attached to the plated parts, even when the plated parts are lathe tools, it will not affect its protection and surface hardening performance. The thickness of PVD vacuum coating is about 0.3 m ~ 5m, so it can improve the physical and chemical properties of the workpiece without affecting the original size of the workpiece, keeping up with diamonds-DLC-like diamond coatings are generally used to harden the surface of PVD coatings by using titanium nitride, titanium carbide or titanium oxide, although the performance is not poor (surface hardness is about 2000-3000 HV) , but there is still a risk of scratches for heavy watch lovers. To avoid this, it seems unlikely that even diamond-like carbon (DLC) , which has a harder surface than diamonds, could be used to make clocks. DLC is a Chemical vapor deposition technique in which carbon atoms are deposited on the surface of the workpiece in a vacuum with the help of an inert gas to form dense layers of diamond crystals, and because these carbon atoms are all treated to have double bonds, the bonds between the atoms are very tight, the surface hardness (about 3500hv) , stability and smoothness of the DLC-treated parts can surpass those of the traditional ceramic materials, but because the cost is much higher than PVD, so currently only seen in the high price of watches above the use. In addition to DLC, there is a higher-order ADLC (AMORPHOUS-DLC) Diamond-like carbon coating technology, has been used in a small number of wristwatch manufacturing. Conventional DLC coating can still show irregular crystalline structure under electron microscope, which has an effect on the overall strength, while ADLC coating can be observed under electron microscope, is a layer such as mirror-like close to the plated parts of the perfect coating, surface hardness has been greatly enhanced to a maximum of about 6000hv! About half of the natural diamond, is the most powerful surface coating technology. And whether DLC or ADLC, have not easily contaminated another advantage, and this also greatly enhance the use of DLC, ADLC technology wrist watch practicability.

It is very important to clean the surface of vacuum plating, which directly affects the quality of electroplating products. Before entering the plating chamber, the workpiece must be carefully cleaned before plating, the surface pollution comes from all kinds of dust, lubricating oil, oil, polishing paste, grease, perspiration and so on which the workpiece adheres in the process of processing, transmission and packing, vacuum plating manufacturers can basically be used to oil or chemical cleaning methods to remove it. The clean surface after cleaning treatment, can not be stored in the atmosphere, to use a closed container or cabinet storage, to reduce dust contamination. Storage of glass substrates in rigid, oxidized aluminum containers minimizes the adsorption of hydrocarbon vapors. Because these containers preferentially adsorb hydrocarbons. Vacuum coating processing for, highly unstable, water vapor-sensitive surface, generally should be stored in a vacuum drying box. Vacuum coating process to remove dust coating room, set a high degree of cleanliness of the work, workshop, to maintain a high degree of cleanliness of the environment is the basic requirements of coating process. In areas with high air humidity, in addition to the substrate before plating, vacuum chamber parts, pieces of serious cleaning, but also for baking degassing. To prevent oil into the vacuum chamber, pay attention to the oil diffusion pump back oil, high heating power of the diffusion pump must be taken oil-blocking measures.
