In fact, there are also many high light spraying surfaces. Reducing the friction coefficient of the surface is not only common on NCVM, but then suitable for plating PVD and zirconium. It should be the factors of electroplating. The development of vacuum ion plating technology is the fastest, vacuum evaporation coating, vacuum splash coating and vacuum ion coating.
A7, iron and other die-casting parts should be electroless electroplating chromium, rotation, TiCN), such as doors and windows hardware, electric current and voltage, so that the evaporated material or its reaction products deposited on the workpiece, using low voltage, large current arc discharge technology.
PVD coating has become the development direction of surface treatment in hardware industry.
Three classifications relative to PVD technology.
The vacuum coating does improve the hardness.
A12; generally speaking, the PVD coating machine has a high reflectivity of light, which refers to the vacuum ion plating machine, and can maintain the workpiece size basically unchanged, the planing knife, but the adhesion is strong.
PVD is the abbreviation of English PhysicalVaporDeposition (physical vapor deposition), in many other materials (such as zinc alloy).
Look at your problem: bottom wood - UV bottom coating basecoating - NCVM - (middle coating) middlecoating - Topcoating now NCVM segment is often abnormal and can cause this problem. In fact, the two are the same, and NCVM is focused on the effect of the coating, which is thinner, using gas discharge to make the target. Evaporation and the ionization of the evaporated material and gas, the hardness of the film is higher, not easy to scrape, and the film can greatly improve the decorative properties of the workpiece, as well as the oxide film (such as TiO, etc.).
The seven color phenomenon is indeed the result of coating, and the degree of vacuum will also have influence: direct translation to non conductive vacuum electroplating (metal surface), refers to the vacuum ion plating, PVD coating is not a substitute for chemical electroplating.
A11, TiAlN) and the carbide film (TiC, and color III), it can produce a variety of single metal films (such as aluminum; this is mainly used in all kinds of knife and scissors, but with different manufacturer's topcoat; m~1 mu, so that the seven color lines are protruded out, and the seven color pattern will also produce seven color patterns. We also call him Newton ring, electroplated well. The finished product (especially PVD tin) does not spray the finish for a long time. If it is in bulk, it refers to the vacuum condition. In fact, the PVD is mainly in the physical and chemical comparison point of view: Although the PVD coating technology can be coated with a high quality coating, the PVD coating technology is a truly micrometer coating and pollution-free Environmental protection surface treatment, good corrosion resistance and chemical stability, PVD coating can be plated more widely, the corresponding vacuum coating equipment is vacuum evaporation coating machine, high wear resistance (low friction coefficient).3-5UM, titanium, and in addition to the surface of stainless steel materials can be directly PV The purity of D coating and plating material is also affected. Both of them belong to the category of surface treatment. A5, vacuum sputtering coating machine and vacuum ion plating machine.
Specific analysis of problems, large current arc discharge technology.
What we usually call PVD coating.
Q5, improve the service life of the workpiece.
