There are still many people concerned about the silver coating method of pvd coating machine. Not long ago, a customer asked me this kind of question. Today, the editor of Huicheng Vacuum will introduce it to you in detail. By the way, I will also help you sort out the vacuum. The application range of coating machine, I hope to help you:
There are several ways to get a bright silver coating on the pvd coating machine, we can take a look.
1. Brushing: After ordinary silver plating, although the surface of the parts is evenly coated and the crystals are fine, it is not bright. The bright silver layer can only be obtained by brushing the surface of the part with a copper wire brush or copper wire wheel.
2. Pulse silver plating: Compared with ordinary silver plating, the obtained plating layer is not only finely crystalline and dense, but also has better dispersion ability and deep plating ability than ordinary silver plating. A glossy silver coating can be obtained without the use of brighteners.
3. Bright silver plating: Whether it is cyanide silver plating or cyanide-free silver plating, as long as appropriate additives and brighteners are added, not only a full-bright silver coating is obtained, but also the coating is more detailed, with good reflective performance, and the dispersing ability of the plating solution and Throwing power is also improved. By adding additives, coatings with different properties can also be obtained, such as semi-bright coatings, full-bright coatings, improving the weldability of the coatings, and increasing the hardness and wear resistance of the coatings.
Generally, there are only three silver coating methods for vacuum coating equipment, and these three are relatively common.
Which industries are pvd coating machine generally used in?
Pvd coating machine mainly refers to a type of coating that must be carried out under a high degree of vacuum, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and many others. Vacuum coating equipment is generally used in the following industries:
(1) Furniture, lamps and hotel utensils.
(2) Stainless steel tubes and plates (various types of surfaces).
(3) Large workpieces: automobile hubs, sculptures, stainless steel plates and signboards, etc.
(4) Watchmaking: It can be used in the coating of watch cases, crystal products and watch straps.
(5) Other hardware: leather hardware, stainless steel tableware, glasses frames, knives, molds, etc.
(6) Building hardware, bathroom hardware, door locks, door handles, bathroom, door locks, hardware hinges, furniture, etc.
(7) Metal products such as locks, handles, bathroom hardware, golf heads, stainless steel tableware, and blood vessels are plated with superhard decorative films.
(8) Watches, watch straps, glasses, jewelry and other accessories, plated with super wear-resistant decorative nano-film and nano-film and nano-laminated film.
