The advantages of sputtering coating film

The advantages of sputtering coating film

Sputtering vacuum coating method, because of its different coating methods, the effect of the same film coating material prepared will be different, although the naked eye can not see it, but it does have certain advantages.
Film thickness, good stability, due to the sputtering target film thickness and discharge currents have a great relationship, the higher the current, the greater the sputtering eff...iciency, within the same time, the thickness of the coating layer is relatively big, as long as the current value of a good control, you need more than a thick plating, or more thin layers can be, of course, this thickness is within the allowable range, and control the current, regardless of how many times repeated plating, the film thickness is not will change the thickness of the film thickness can be attributed to the stability of good controllability and repeatability.
Film with strong, during the sputtering process, some electrons strike the substrate surface, and activating the surface atoms, and produce clean effect, the energy energy-plated material obtained by sputtering evaporation obtained higher than 1 when the two orders of magnitude, such a plating material having a high atomic impact energy to the substrate surface, more energy can be transferred to a substrate, produce more heat, so that the activation of atoms by electrons accelerated motion, and the part plated metal atom earlier fused together with each other, other plating material atom tight with successively deposited film, strengthening the binding force of the film and the substrate.
A wide range of plating material, due to sputtering by argon ion bombardment makes high speed plating material sputtered out, unlike Evaporation and restrictions due to the melting point of only using a relatively low melting point metal plating, sputtering and almost all the solid material can become coated material.
You can see from the above points Sputtering is indeed better than the evaporation vacuum coating effect, a different principle determines the thickness of the film is more stable sputtering, combined with stronger, broader-plated material.

The principle of PVD coating technology

The principle of PVD coating technology

PVD is English Physical Vapor Deposition, in Chinese means "Physical Vapor Deposition", is refers to under the condition of vacuum, use Physical method to make material preparation technology of thin film deposited on the plated workpiece.
2. The PVD coating and PVD coating machine:
PVD (physical vapor deposition) coating technology is mainly divided into three categories, vacuum evaporation coating, vacuum... sputtering plating and vacuum ion plating. Corresponding to the three categories of PVD technology, the corresponding also have vacuum evaporation coating machine for vacuum coating equipment, vacuum sputtering coating machine and vacuum ion coating machine of the three. For nearly 10 years, the development of the vacuum ion plating technology is the fastest, it has become one of today's most advanced surface treatment method. We usually say of PVD coating, is refers to the vacuum ion plating; Commonly referred to as PVD coating machine, namely vacuum ion coating machine.
3. PVD coating, ion plating technology, its particular principle is under the condition of vacuum, with low voltage, high current arc discharge technology, by use of gas discharge from target material evaporation and evaporation occurs matter and gas ionization, using electric field acceleration, cause the evaporation material and the reaction product deposition on the workpiece.

Coating principle is what?

Coating principle is what?

At present there are three kinds of commonly used PVD: vacuum evaporation, sputtering deposition and ion plating. They work as follows: really empty plating film is in 1.33 x10 ^ 3 and 1.33 x10 ^ - 4 under the pressure of pa, with heat source heating material such as electron beam evaporation, evaporation of atoms or molecules directly on the workpiece surface sediments. Sputtering coating: it is not the evaporation technology of physical vapor deposition method. When plating, the studio into a vacuum, into argon as working gas, and maintain its pressure is 0.13 to 1.33 Pa. Ion plating: is it under the condition of vacuum, the use of gas discharge so that gas or evaporation material ionization of evaporation in the gas ion or material under the action of ion bombardment, evaporation, material or other reactant vapor deposition on the workpiece.
Vacuum coating is mainly refers to a kind of need to be done under high vacuum coating, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, laser sputtering deposition and so on many kinds of PLD. The main idea is divided into evaporation and sputtering.
Need coating known as substrate, the plating material is become a target. Substrate with target in the vacuum chamber.
Evaporation coating is to heat the surface of target component to groups of atoms, or ions form by evaporation, and sedimentation in the substrate surface, through the film-forming process (scatter - island structure - the vagus structure - layered growth) form the membrane. For sputtering coating, can be simple to 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 eventually deposited on the substrate surface, experience the film-forming process, eventually form a thin film.

Technical requirements UV lamp vacuum coating paint

Vacuum coating due to radiation-curable coatings green and high efficiency, makes the technology in the world gained widespread attention and rapid growth, its applications more widely. UV coating layer having excellent surface smoothness, is suitable as a primer for the vacuum metal coating technology, available very bright metal appearance on the plastic substrate.

With the development of the automobile industry, many metal replacement technology has been applied, the current car headlight reflector applications, has been fully adopted in the PC, BMC and other plastic surface by vacuum metallized to increase the reflection effect for this area the UV coating requires a good leveling, high temperature resistance (for PC substrates require more than 120 ℃, BMC substrates up to 180 ℃)....

In the design of PC reflector headlights when using UV primer, pay attention to increase the crosslink density coating the coating to ensure a good closure, by adjusting the ratio of reactive diluent formulations to the coating and the substrate, adhesion between the coating and the coating to achieve the best, the complex structure of the workpiece, pay special attention to ensure that the site is not sufficient UV radiation can be completely cured. The main reason for the vacuum coating UV primer requirements before vacuum coating to a plastic substrate surface UV coating has the following two points:

First, when the base is closed by UV coating, vacuum coating, or prevent the use of the escape of volatile impurities in the substrate workpiece, affect coating quality. Like when the lamp reflector applications, due to the use of the process temperature rises above 100 ℃, if volatile impurities in the substrate will release the aluminum layer hair color, color, affect the reflection effect. Figure 1 (omitted) for the DSC curve PC plastic, this figure shows the PC when the substrate has a temperature of about 90 ℃ significant heat flux, may be considered material to release a glass transition temperature Tg of about 140 ℃, the material use temperature should be below this temperature.

Second, to improve the flatness of the substrate surface, ensure the coating mirror effect. Generally plastic surface roughness 0.51nn around itself, vacuum coating thickness does not exceed 0.2μm, was unable to fill the uneven surface of the substrate, are not ideal mirror effect, UV coating thickness of 10-20μm, surface flatness 0.1μm or less, you can fill the substrate coating defects and get the desired effect. For PC material headlight reflector of UV coating must have the following basic characteristics:

(1) leveling state is good, bright paint film, so you can make sure that there is a complete vacuum coating of reflective film.

(2) coating with seal action, ensures the escape of PC substrate does not affect the coating composition at 120 ℃ time.

(3) the coating itself has a certain heat resistance, 120 ℃ will not have material effect on the decomposition release coating.

Leadingcoating structural principle PVD coating vacuum system

 

  Film coatin​g machine as the name suggests is to achieve substrate by PVD coating technology machines use a vacuum environment, Leadingcoating a manufacturing vacuum PVD vacuum coating equipment manufacturers, equipment has the following advantages: (1) with excellent adhesion. 2 high oxidation resistance, high hardness, high wear resistance. 3 is generated in large quantities. 4 does not limit the shape and size. 5 others on request.
  PVD equipment considerations: First, boot first check the flow of water to determine the cooling towers, vacuum pump is working properly, check the gas line is smooth, determine the compressor is working properly. Second, to determine the membrane material in the vacuum chamber, the ion source filament, the workpiece holder is placed as required. Third, after the process is completed to close the electron gun and ion sources, such as switches, to be vacuum coating equipment cooling disappears before turning off the power. Four, can not shop without permission electrical cabinets, vacuum chamber PSD.
  Arrangement PVD coating body determines the overall structure of the PVD coating. Intake and exhaust ports horizontal vertical structure set PVD coating, PVD coating assembly and connecting pipes are more convenient. However, a higher center of gravity PVD coating, PVD coating poor stability at high speeds, so this type are used for small PVD coating. Sometimes in order to facilitate the installation and connection pipe vacuum system can be PVD coating vent pick out from the horizontal direction, that the intake and exhaust direction is perpendicular to each other.
  PVD coating can vent openings from the left or the right in both directions, PVD coating in addition to the exhaust pipe connected to one end, the other end of the bypass valve blocked or access. This PVD coating structure low center of gravity, good stability at high speeds. Generally large and medium-sized multi-use this PVD coating drive shaft coupling and motor coupling through. PVD coating has the following two main structural arrangement on the drive: one is the motor and gear on the same side of the rotor as shown. PVD coating rotor driven directly by the motor side gear drive transmission in the past, such a small rotor shaft torsional deformation of the initiative, the gap between the two rotors will not reverse the drive shaft of the large deformation and change, PVD coating it makes between the rotor the gap is even during operation.
