Works multi-arc ion plating machine and application description

Multi-arc ion vacuum coating machine is an efficient, safe, pollution-free ion plating equipment, with deposition speed, ionization rate, ion energy, the equipment is simple, low cost, the advantages of producing a large quantity.
Ion plating fact ion sputtering, the conductive target, DC bias power supply; non-conductive targets, using pulsed bias supply. Some multi-arc ion coating machines, you may also need a DC arc or pulsed arc power supply. Bias power supply is in fact between the cathode and the anode position sample bias electric field where the formation is generally negative high voltage cathodes. Free electron emission cathode surface directional acceleration in the electric field emission electron impact gas molecules, so that the ionization, and the gas is expelled electrons are accelerated by the electric field of continuing ionized molecules of other gases, continuous form avalanche effect, hit the gas wear, the formation constant of ionization current. In this case ions are accelerated to bombard the target, the target material atoms expelled surface, and deposited on the sample surface.
Application of multi-arc ion coating machine, multi-arc ion coating machine for different grades of hardware products, general construction hardware, locks, multi-arc ion plating equipment capable, high-grade products such as strap, case, glasses , mobile phone shell, golf equipment, sanitary ware, jewelry, and other commonly used arc / IF (+ DC) magnetron sputtering composite coating equipment, the choice of the size of the models based on loading. The device can be plated gold color, rose gold, brown, brown, tan, blue and other decorative film.

Multi-arc ion coating machine for super hard film coating

Multi-arc ion coating machine for super hard film coating

Taking use of multi arc ion coating technology can do coating film on metal,alloy,and electrically conductive material(substantially non-conductive material) (using high-frequency bias). Multi-arc Ion plating film can be deposited by metal film, multi-alloy film, compound film; Can be single plated coating and also composite coating film can also be plated coatings and nano-multilayer co...ating gradient.
Vacuum ion plating equipment coating products, including drills, milling cutters, gear cutters, broaches, taps, scissors, shave blades, molds, injection molding, magnetic forming die, punching die, automotive and medical equipment, and other wear parts.
Ion plating technology is particularly suitable for the deposition of hard film. Ion plated hard and wear resistant coating film as super-hard anti-wear protection film is widely used in tooling, film tools, wear parts. Common membrane system comprises TiN, ZrN, TiAIN, TiC, TiCN, CrN, AI2O3 and the like. In addition, there are more hard DLC (DLC), TiB2 and carbon and nitrogen (CNX) film.
Ion plating technique can be applied in addition to ultra-epidural, and also for the preparation of other features, such as the head of the DLC protective film micro gyro bearings dry solid lubricant film (MoS2, DLC), and a variety of magnetic film series feature film, communications and electronic devices

The harmfulness of coating machine

The harmfulness of coating machine

A large amount of gas or fuel will all be loss, high pressure gas storage or fuel gas cylinder and tank if there is a leak, caused a certain economic losses.
Internal to the device and atmosphere pollution caused by the only allowed to work in some gas, some microelectronics devices not only require work under certain pressure. Vacuum evaporation coating machine so that its internal to filling the maintenance of gas in general. However, due to the leakage hole presence of harmful gas in the external environment may leak through hole to the interior of the device or devices, and make the device internal gas composition changes, which cause pollution, make the device does not work even failure.
Arc ion coating machine type more atmospheric pollution environment these harmful substances into the atmosphere environment, containing flammable, explosive, toxic, radioactive and other harmful to people's physical health material storage tank once has the leakage. On atmospheric environment pollution, affects people health. Some inflammable, explosive qualitative leak detection, and burning and explosion may occur, endanger people life and peace.

Vacuum coating machine dehumidifier?

Vacuum coating machine dehumidifier?

Vacuum is to support the environment of the operation of the vacuum coating machine need high vacuum equipment, in particular, we usually need to achieve high vacuum degree, the effect of extraction system is played, but besides extraction system, in the process of vacuum coating equipment operation, and is, degassing of artifacts.
Some artifacts itself inside there are a lot of gas, water, etc., these substances will be as device heating when the emissions in the vacuum chamber, reduces the degree of vacuum, what is more, some toxicity gas composition, direct damage to the vacuum chamber of the mechanical structure, the equipment can't normal operation.
In addition, is coating process, due to heat the gas in the expansion of workpiece, easy to split has plating layer on the membrane, the probability of this problem, of course, depending on the artifact itself physical properties, easy expansion, such as plastic probability is relatively high, hard, such as metal probability is lower, but also cannot ignore, so the workpiece degassing is very necessary.
We usually use the degassing method of workpiece is baking, by heating the piece in the gas, water discharge, before coating, extraction, heating the workpiece, when the workpiece in water and gas due to heat released after, together with vacuum indoor gas by a pump.
According to different workpiece different degassing measures, effectively control the workpiece internal gas and water discharge, improve the stability and uniformity of coating.
