Vacuum evaporation coating machine the resistance of the coating

Vacuum coating technology is now a more environmental way of surface treatment, the coating way compared to the general chemical coating or plating is better. The adoption of modern vacuum technology, so this kind of coating relative to some other way of surface treatment is more superior, because to deal with things in the vacuum environment, vacuum evaporation coating machine now using this technology, can greatly reduce the external factors on the impact of items in the coating process.
 And with the continuous development of technology, currently use a coating, vacuum coating machine for objects to give the particle surface more membrane layer, thus formed the film also has higher wear resistance properties. The vacuum evaporation coating machine is a class of more traditional in the vacuum coating equipment. And this kind of coating machine is now also have a lot of kinds of types, including using resistance coating equipment, also known as resistance evaporation coating machine. This equipment is mainly used in the form of a resistance heating evaporation on the coating material, make the material attached on the surface of the items that need to coating, such as after the formation of a layer of film cooling. This is at present the basic resistance vacuum coating machine for use.

The influence of vacuum coating machine to our country economy

             

 Vacuum coating machine to improve the living standard of people has a great importance, as people's living standard is higher and higher, the proportion of coating industry is located in the national economy is more and more big, because of the demand of the market also gradually increase, is also more and more high to the requirement of coating products.
 There are many different kinds of coating equipment, according to the different process can be divided into evaporation, magnetron sputtering, ion and PVD coating technology, according to the requirements of each coating processing enterprises also need to configure the different equipment and procedures.
Now our country should be very mature for vacuum coating equipment has its own system, after decades of development, all of them are varieties of match, is suitable the market and the development of coating industry development system, so is not a new line

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 influence 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.

The development potential of vacuum plating equipment

   

  Vacuum plating equipment refers to a kind of need to be done under high vacuum coating, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy etc. A lot of kinds, but more common are two evaporation and sputtering. Evaporation coating is generally by heating target material to make the surface of target components form groups of atoms, or ions evaporate, make its settlement in the substrate surface, form a thin film through further film-forming process.
 For sputtering deposition, we can understand for the use of electronic or high-energy laser bombardment of target, and the surface components form groups of atoms, or ions was sputtering, and deposited on the substrate surface, through further film-forming process, eventually form a thin film. Two ways shall be carried out under the high vacuum environment, so called vacuum coating technology. Vacuum plating than traditional electroplating water, good development potential, the environmental pollution is small, low cost, make product metal sense is strong, high brightness, is widely used in various industries.

Ion coating machine coating pretreatment process

               

  Working principle of ion coating machine is certain vacuum condition, by gas discharge, work or membrane material part of gas ionization, evaporation in the gas ion or material under the action of the bombardment of ions, the evaporation or reactants form a thin film deposited on the substrate surface. Ion coating machine coated in one of two ways, one is evaporation ion plating, the other is a sputtering ion plating. Evaporation is ion plating by heating membrane material, to produce metal steam, and then through different ways to motivate steam discharge, ionization deposited into a film. Sputtering ion plating is produced by high-energy ion sputtering film material on the surface of metal particles, then in gas ionization discharge space into a metal ion, the deposition film on the substrate. Vacuum ion plating for sedimentary hard film, widely used, such as cutting tools, wear-resistant parts surface.
Before with ion coating machine made plating film, is needs a sample test according to the needs of users, the following brief introduction:
1, first, and customer communication, to understand the performance and usage of samples;
2, analysis of samples, the performance, surface state, etc.;
3, choose before processing link;
4, depending on the type of surface shape, pollutants such as choosing pre cleaning;
5, test before treatment effect;
6, test samples, if qualified, compiling process, formally put into production.

Vacuum coating machine equipment characteristics of the vacuum coating machine system

                       

  Vacuum coating machine in plasma beam sputtering, uniform sputtering ion etch target surface, and will not make the target surface oxidation. Compared with magnetron sputtering, the plasma beam is generated by the rf plasma source and the role of the magnetic field is the plasma beam convergence and deflection to the target surface, therefore, although plasma beam sputtering coating system also has a magnetic field, but its effect to the magnetic field does not control sputtering, which abandoned the magnetron sputtering caused by uneven magnetic field in the "magnetic control" shortcomings. In sputtering, after the completion of the target material utilization rate can be as high as above 90%.
  Vacuum coating machine, magnetron sputtering and plasma beam sputtering target surface etching after contrast figure. Due to greatly improve the utilization rate of target material, has solved the difficult to overcome shortcomings of magnetron sputtering, which results in uneven etching of the target poisoning
Vacuum coating machine in addition, magnetron sputtering produce sputtering runway due to uneven magnetic field on the back of the magnet, the magnetic field is prone to oxidation zone, so it is difficult to deposit of ferromagnetic materials, and in the plasma beam sputtering with no magnet as plasma constraint, ability of ferromagnetic material coating, and can use the thick target material, in figure 3 experimental cobalt metal thickness is 6 mm. For iron, nickel,  chromium and ferromagnetic compounds, plasma beam sputtering are also has a high sputtering rate.
A further advantage of application of the coating technology system, when the electromagnetic coil polarity reverse connection, due to the direction of the magnetic field produced change, plasma beam bombardment under the action of a magnetic field of the substrate, thus substrate cleaning action, as shown in figure 4. This can actually make the application of the technology of coating machine to omit conventional coating machine cleaning with ion source.
