Chromium plating is an ideal coating method to give products high mechanical properties. At the same time, it has attractive metal appearance and aesthetic impact, which increases the added value of products. Compared with traditional electroplating, uv-pvd combination is safer, more economical and more environmentally friendly. Therefore, traditional electroplating is gradually eliminated.
Using vacuum sputtering technology, harmful emissions are completely eliminated, and environmental friendly chromium plating is developed instead of electroplating. The process cycle is very fast, and its excellent performance is transformed into efficient and economical green production. Uv-pvd chromium plating process is environmentally friendly. It works at room temperature without water consumption and chemical discharge. By reducing production time, repetition cycle and minimizing defects, it ensures high cost-effective processing cycle, low cost consumption and high productivity.
In addition to chromium coating, it can also be plated with silver, providing a very wide range of design options and design color diversity in terms of color and effect.
Diamond like carbon (DLC) coating is often used in automobile engine to reduce the friction of engine. The black color makes DLC coating popular as decoration coating (such as watch). Because of its low friction and non adhesion coefficient, DLC coating is well used in tool coating. DLC coating technology is very suitable for machining and casting / forging, as well as coating of aluminum and plastic injection mold.
DLC coating technology:
Different types of diamond-like carbon coatings have different production technologies. DLC coating is suitable for extreme wear and high relative speed, even in the condition of no lubrication operation. It has excellent wear resistance, anti-oxidation and adhesion (anti-wear). It can withstand the surface pressure that will immediately lead to wear and cold welding under normal conditions, reduce the friction loss to the minimum, and good corrosion resistance can prevent the matrix from damaging attack.
HCVAC applies its long-term experience in carbon based coating process and vacuum coating equipment technology to metal bipolar plates of fuel cells. Good results in adhesion, conductivity and corrosion resistance have been obtained by plasma surface cleaning and special bonding layer in the coating cavity.
The company mainly provides metal bipolar plate coating equipment to the market, and can provide coating materials according to customers' needs, including graphite and precious metals. The cost value of small batch experimental production equipment and mass production is very consistent with the industrial route.
HCVAC antibacterial coating combines the strength, durability and beauty of PVD coating, and has excellent antibacterial performance. Its antibacterial properties can inhibit the proliferation of pathogens that may infect the surface. All daily articles that may contact people need this type of coating.
Thanks to the innovative coating process developed by HCVAC, the antibacterial coating can not only completely inhibit the growth of bacteria, but also eliminate them to ensure the complete sanitation of the surface.
The precise laboratory tests prove that this antibacterial efficiency is caused by the nano embedding in the complex structure of the multilayer coating, which destroys the bacterial cell membrane by blocking its nutrition and interrupting the cell division cycle.
Antibacterial and antiviral effects
Due to the physical properties of the coating, the antibacterial effect continues throughout the life of the object and improves over time.
Thanks to its antiviral effect, it is a completely hypoallergenic product. In addition, according to DM 3/21/1973 test, the coating is completely safe for human contact.
Antibacterial color and substrate
The antibacterial properties of HCVAC antibacterial coating combine with the aesthetic quality of PVD coating: hardness, UV resistance, high color stability and scratch resistance.
Antibacterial coatings can be applied to many different types of substrates: ferrous and non-ferrous metals, polymers such as ABS and polycarbonate (with appropriate pre-treatment).
The efficacy of HCVAC antibacterial coating has been tested against the bacteria of Escherichia coli (Gram negative) and Staphylococcus aureus (Gram positive) strains. These two bacteria belong to the popular bacteria family that are most responsible for "contact infection", and have achieved excellent results on newly produced samples and products that have been used for a long time.

At present, AR film is mainly used in telescope, glasses, digital camera lens, LCD projection system, optical window, protective mirror, notebook, computer, mobile phone, TV, glasses, touch screen, etc.
Structurally, AR film can also be divided into single-layer antireflection film and multi-layer antireflection film:
Single layer antireflection film in order to reduce the reflected light on the surface, the simplest way is to coat a layer of low refractive index film on the substrate surface.
Multilayer antireflection film is called multilayer ar film when more than two layers of reflective materials are plated on the film. Multilayer has better performance than single layer.

Compared with traditional magnetron sputtering, ICP sputtering optical coating adopts metallization sputtering first, and then reacts with metal film through ionization reaction gas to synthesize dielectric film. Its process cavity always maintains vacuum in a PM (maintenance) cycle, providing a stable and reliable coating environment and higher production efficiency. It is suitable for plating AR, superhard AR, bbar film, mirror, ncvm, filter and other optical films on the plane or curved surface of glass, plastic and other substrates. It can also realize the plating of AF / as film. ICP source is used for substrate cleaning and auxiliary deposition in evaporation / sputtering process:
Electron gun auxiliary: it can pass a variety of gases. In addition to auxiliary, some applications can be protected by a layer of DLC after plating;
PVD auxiliary: mainly used for oxygen and nitrogen supplement applications, suitable for oxides and nitrides. In the case of high-speed sputtering with metal target, the ICP source is used to supplement oxygen or nitrogen for oxidation or nitridation, so as to realize the rapid preparation of high-precision optical films by magnetron sputtering.
Advantages of ICP:
Increase the plasma density, especially the ionization rate of inert reaction gas
High energy particle bombardment to improve the film density
Improve the film-forming quality and avoid high-temperature process
Change the crystal structure of the film to change the chemical or electrical properties of the film
CCP capacitively coupled plasma
The principle of capacitance coupled plasma is different from that of inductively coupled plasma. Capacitive coupling is made of grounded discharge chamber (made of materials with small composite coefficient, such as quartz) and introduced drive electrode as coupling element. The driving electrode is plated with ceramic materials with low sputtering yield to reduce the sputtering of ions on cathode materials. When connected to the power supply, a high-frequency electric field is generated between the discharge chamber and the drive electrode, under which the free electrons move up and down, and discharge is excited. Since the free path of electrons is much larger than the size of the discharge chamber, they are multiplied mainly by the secondary electrons they knock out of the tube wall. The latter becomes the maintainer of this discharge, and the secondary electrons generated by gas ionization will play a secondary role.
