Principle of rf sputtering coating machine

Principle of rf sputtering coating machine
Exterior burnish products, in fact, most of them are used the surface treatment, and said to the surface treatment, now of the coating is one of the typical type of surface treatment. And this kind of surface treatment of the main characteristic is that after coating makes the product's surface is covered with a layer of thin film and have the function of the isolated from the outside factors influenc...e its surface. And the other is generally after coating, the surface has a certain iuster, for the products, improve the appeal. Now, use a lot of coating machinery, including the control sputtering coating machine, vacuum evaporation equipment, to introduce below the peak sputtering coating machine.
Vacuum coating machine in a vacuum chamber, applying frequency to set two plates and in more than 50 kh high-frequency electric, is a small amount of electrons in the high frequency electric field in the high frequency electric field under the action of accelerating, collide with gas molecules, make gas ionization and emitted electron, the electronic and high frequency electric field will be accelerated, eventually forming the high frequency glow discharge. Radio frequency glow discharge of glow there is no difference between the two electrodes, each with a cathode dark space and negative hui district, plasma column between the two poles. Input coupling mode of high frequency power supply mode with capacitive coupling and inductance coupling, which is currently an internal principle of splash control sputtering coating machine, also because this principle makes the sputtering coating machine to use stability.

How to reduce the vacuum coating of dust?

How to reduce the vacuum coating of dust?
Through long-term practice, summed up dust factors affecting the effect of vacuum evaporation coating machine coating and matters needing attention:
1. The coating after a period of time, the inner wall of the vacuum coating machine must be clean;
2. The staff have special clothing, light coating machine operation to wear gloves, socks, etc.;
3. Clean the substrate material, must be strictly accord with technical requirements;
4. Use the purity of source materials to meet the necessary requirements;
5. The sample out after placing environment to pay attention to the problem of clean;
6. The appropriate increase the humidity environment, multi arc ion coating machine can lower the suspended solid particles of the surrounding environment;
7. Technically explicitly allow maximum particle size and the number of particles per unit area of the ceiling is roughly how much;
8. The indoor air flow is low, the ground clean, splash control sputtering coating machine if it is a bare concrete, need to deal with the cover. Walls, roofs, cannot use the general grey coating paint.

The characteristics and advantages of vacuum coating machine

The characteristics and advantages of vacuum coating machine
As the main vacuum equipment, at present in the surface treatment can play a good effect of vacuum coating machine is to use more kind, and this kind of equipment is not in the real operate under vacuum condition. Because true vacuum environment is still need very high conditions, need technology is also very high, at present is difficult to achieve in the machinery. Here said the vacuu...m mainly refers to the environment, relative to the vacuum and the vacuum coating equipment in such an environment, processing technology is used to analyse the articles needed in coating coating process.
Compared with the general surface treatment device, the mechanical plating advantage in where? It can form a layer of thin film on the surface of objects, and the film has some characteristics of the coating material. That is to say this kind of vacuum coating technology can make objects have a certain performance improvement, take plastic coated materials, for instance, by vacuum evaporation coating machine can make objects are after coating, has certain corrosion resistance properties, and on the surface of the membrane layer can also play a role wear-resisting, to protect the goods have some improvement.
This is the characteristics of this kind of coating equipment, as well as its main advantage, at present some of the metal objects or the lens material is using this kind of coating machine to surface treatment.

Introduction to the vacuum plating equipment common vacuum coating method

Introduction to the vacuum plating equipment common vacuum coating method
Vacuum plating equipment is used for a class of need in the vacuum coating equipment, coating method is called vacuum coating method. Vacuum coating method is in the heart of the vacuum evaporating metals, alloys or compounds (or sputtering), make them deposited on the surface of the substrate, method. On the material surface plating a layer of thin film, can be material to... obtain some new chemical or physical properties. Vacuum coating method is a new coating process, also known as dry coating method, compared with the wet plating method, it has the features: 1, the film less susceptible to pollution, get good coating compactness, high purity. 2, wide range of membrane materials and the selection of base material, the film thickness can be controlled, with different vacuum plating equipment preparation of different functional thin film. 3, membrane layer and substrate adhesion, strong. 4, does not produce waste, not cause environmental pollution.
Common coating methods include vacuum evaporation, sputtering, ion plating, etc. These three coating methods have their advantages and disadvantages, including ion plating used most widely, its characteristic is: can plating materials including metals, alloys, compounds, such as membrane material evaporation method with evaporation and sputtering, membrane layer adherent strength is good, the plating film density high, uniform, can all plated surface.

Multi arc ion plating technology and its application

Multi arc ion plating technology and its application
Multi arc ion plating technology is an improved method of the ion plating technology, it is the arc discharge as evaporation source of metal surface coating technology. Because of multi arc ion plating technology has high deposition rate, film density is big, good adhesion of the membrane and other characteristics, make more arc ion copperplating layer in tool and mould of hard coating, decorative coating is more and more widely in the areas of application, and will occupy more and more important position. This paper introduces the principle of multi arc ion plating technology, features, and sums up and summarizes the past, on the basis of a large number of experimental studies and literature at home and abroad, analyzes the technological development of multi arc ion plating technology and its application in various fields, for the future research and application of multi arc ion plating technology provides the beneficial reference.
