1. Thermal CVD technology
Hard coatings are mostly metal ceramic coatings (TiN, etc.), which are formed by the reaction of metal in the coating and reactive gasification. At first, the thermal CVD technology was used to provide the activation energy of combination reaction by thermal energy at a ...
Resistance evaporation source coating is a basic vacuum evaporation coating method. “Evaporation” refers to a thin film preparation method in which the coating material in the vacuum chamber is heated and evaporated, so that the material atoms or molecules vaporize and escape from the...
The cathodic arc ion coating technology uses cold field arc discharge technology. The earliest application of cold field arc discharge technology in the coating field was by Multi Arc Company in the United States. The English name of this procedure is arc ionplating (AIP).
Cathode arc ion coatin...
There are many types of substrates for glasses and lenses, such as CR39, PC (polycarbonate), 1.53 Trivex156, medium refractive index plastic, glass, etc. For corrective lenses, the transmittance of both resin and glass lenses is only about 91%, and some of the light is reflected back by the two s...
1.The film of vacuum coating is very thin (normally 0.01-0.1um)|
2.Vacuum coating can use for many plastic, such as ABS﹑PE﹑PP﹑PVC﹑PA﹑PC﹑PMMA, etc.
3. The film forming temperature is low. In the iron and steel industry, the coating temperature of hot galvanizing is generally between 400 ℃ a...
After the discovery of the photovoltaic effect in Europe in 1863, the United States made the first photovoltaic cell with (Se) in 1883. In the early days, photovoltaic cells were mainly used in aerospace, military and other fields. In the past 20 years, the sharp decline in the cost of photovolta...
1. Bombardment cleaning substrate
1.1) Sputtering coating machine use glow discharge to clean the substrate. That is to say, charge the argon gas into the chamber,discharge voltage is around 1000V, After turning on the power supply, a glow discharge is generated, and the substrate is cleaned by ...
The application of optical thin films in consumer electronics products such as mobile phones has shifted from traditional camera lenses to a diversified direction, such as camera lenses, lens protectors, infrared cutoff filters (IR-CUT), and NCVM coating on cell phone battery covers.
Camera spe...
CVD coating technology has the following characteristics:
1. The process operation of CVD equipment is relatively simple and flexible, and it can prepare single or composite films and alloy films with different proportions;
2. CVD coating has a wide range of applications, and can be used to pre...
The vacuum coating machine process is divided into: vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating.
1、Vacuum evaporation coating
Under the vacuum condition, make the material evaporated,such as the metal, metal alloy, etc. then deposit them on the substrate surf...
1、What is vacuum coating process? What is the function?
The so-called vacuum coating process uses evaporation and sputtering in a vacuum environment to emit particles of film material,Deposited on metal, glass, ceramics, semiconductors and plastic parts to form a coating layer, for deco...
Since vacuum coating equipment works under vacuum conditions, the equipment must meet the requirements of vacuum for the environment. The industry standards for various types of vacuum coating equipment formulated in my country (including general technical conditions for vacuum coating equipment,...

Vacuum ion plating (ion plating for short) is a new surface treatment technology which is developed rapidly in the 1970s, which was proposed by D.M. Mattox of Somdia Company in the United States in 1963. It refers to the process of using evaporation source or sputtering target to evaporate or spu...
① Anti-reflection film. For example, cameras, slide projectors, projectors, movie projectors, telescopes, sight glasses, and single-layer MgF films coated on lenses and prisms of various optical instruments, and double-layer or multi-layer broadband antireflection films composed of SiOFrO2, AlO, ...
