Vacuum coating and coating technology development and application of explanation

Vacuum coating and coating technology development and application of explanation:

PVD (physical vapor deposition) technology in the late 1970s, began to use in improving the mechanical properties of a hard film, the film is produced with high hardness, low friction coefficient, good wear resistance and chemical stability and other advantages. Initially successful application in the field of high-speed steel cutting tools tool manufacturing caused... the world's attention, the people in the development of high performance, high reliability, coating equipment, also carbide, ceramic knives in a more in-depth coatings applied research. PVD process has no adverse impact on the environment, in line with the development of modern green manufacturing.
Titanium treatment process temperature can be controlled below 150 ~ 500 ℃, so the process can be used for coating titanium substrate of a variety of materials, not only has colorful decorative effect, even more important is the use of PVD technology allows coating has excellent the physical and chemical properties, physical properties greatly enhanced surface hardness, friction coefficient and other indicators such as the matrix.

Magnetron sputtering technology is the key to that?

Magnetron sputtering technology is the key to that?

Splash of sputtering coating machine magnetron sputtering technology has some advantages such as simple operation process, membrane layer high deposition rate, good film performance stability, repeatability and basal and material selection, can be deposited multilayer film, easy to get larger film uniformity. Car paint coating at the same time, magnetron sputtering film ion energy is higher than the thermal evaporation, general under arc plating, therefore, easy to obtain good adhesion, high density, small internal stress of thin films.
And magnetron sputtering technology is easy to implement on the large area uniform deposition of thin films, low cost, make the magnetron sputtering technology is successfully applied in microelectronics, optical thin film, the material of the thin film deposition and surface coating preparation area.
Magnetron sputtering power supply is one of the key equipment of magnetron sputtering technology, its quality fit and unfit quality directly affects the coating quality of the products. At present, the types of the magnetron sputtering power supply dc power supply, intermediate frequency power supply and radio frequency power supply.
The dc magnetron power simple, reliable, stable work, wide application. UV coating production line of sputtering power supply current fluctuations or deviation will directly affect the sputtering rate and the quality of the film, in order to control the quality of the coating, the stability and repeatability, dc magnetron sputtering power supply must have a good constant current characteristics.

What is a vacuum coating machine?

What is a vacuum coating machine?

Vacuum coating machine 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, PLD laser sputtering deposition and so on many kinds. The main idea is divided into evaporation and sputtering.
What is a vacuum coating machine? Light coating machine encountering such as to how to solve? Troubleshooting should detect low vacuum is normal (mechanical pump, roots pump, pipe, chamber, evaporator), the low vacuum is normal to open the main pump, main pump work in normal after testing chamber under vacuum is normal, normal to open the high valve chamber under vacuum is used to detect the high vacuum leak detection, vacuum until reach work, limit vacuum, vacuum, vacuum, such as the limit of vacuum and vacuum is normal, and restore the vacuum and vacuum does not work properly may be there is something wrong with the main pump. Now you to what is called vacuum coating machine should have a general understanding.

Coating application in glasses and cars have to differ?

Coating application in glasses and cars have to differ?

Glasses coating used in camera lens, such as myopia, hyperopia, presbyopic glasses corrective lenses. Vacuum coating machine
Coating is very thin, transparent film on the surface plating. The purpose is to wish to reduce the reflection of light, increase light transmittance, anti-ultraviolet radiation and minimizing down, ghost; Different colors of coating, also make different imaging color balance. In addition, the coating can be delay aging lens, color changing time.
Glasses coating commonly used drugs: zirconium dioxide (ZrO ₂), silica (the SiO ₂), ITO (increase conducting uv lens), HT - 100 (waterproof membrane, prevent aging and oxidation). Splash control sputtering coating machine
Coating principle: high voltage electron gun will be more than several kinds of medicine vaporization, uniformly distributed over the surface of the lens.
Automobile coating and beauty is the highest measures of protection of paint, can avoid oxidation, to brighten up to the paint, acid and alkali resistance, oxidation resistance, resistance to ultraviolet ray and other multiple functions. Because itself is a kind of inorganic membrane materials, no damage to paint. Vertical single door coating machine
In to the car coating, the color of its body due to aging embrittlement of paint and corrosion formation of oxide layer will go away for years. Can increase the surface hardness, avoid scratches and small aperture. Hold time is longest, about more than a year.

Why double door coater coating when two gate voltage difference is very big

Why double door coater coating when two gate voltage difference is very big

Should be a magnetron sputtering, but don't know whether I reaction sputtering, if is reactive sputtering, low voltage film slow is normal. Have not seen a similar coating machine, don't know whether two cavity is same? If not, there may be a flat place, but the speed is fast enough, show that the pressure is no problem. In addition, the stand or fall of magnet tests only target on the surface of the magnetic field strength is good, the higher the magnetic field intensity, the lower the voltage. Power supply is intermediate frequency or dc or rf, twin target, if not need to pay attention to whether the power cord connect anti? Made no mention of target's own reason, may be in the air oxidation, surface to sputter, with fine gauze after polishing time target practice.
In addition, the target water not too cold. When exposed to atmosphere are easy to be surrounded by water. Swap of vacuum coating machine equipment suggested that the two target location, so you can find out the cause of the target and magnet or coating chamber.
