Hot wire arc enhanced plasma chemical vapor deposition technology
The hot wire arc enhanced plasma chemical vapor deposition technology uses the hot wire arc gun to emit arc plasma, abbreviated as the hot wire arc PECVD technology. This technology is similar to the hot wire arc gun ion coating technology, but the difference is that the solid film obtained by ho...Read more -
Introduction to Conventional Techniques for Depositing Hard Coatings
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 ...Read more -
What is resistance evaporation source coating?
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...Read more -
Introduction to Cathodic Arc Ion Plating Technology
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...Read more -
The Application of Optical Thin Film in the Coated Glasses Industry
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...Read more -
Features of vacuum coating machine
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...Read more -
Introduction to solar photovoltaic thin film technology
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...Read more -
