PVD coating (ion coating) technology, the principle is to use low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target and ionize the vaporized substance and gas, using the acceleration of the electric field, The evaporated material and its reaction product are deposited on the workpiece. The film layer coated by PVD coating technology has high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the life of the film layer is longer. Improve the appearance of the workpiece.

PVD Characteristics of coated film layer—The film layer coated by PVD coating technology has high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the life of the film layer is longer. At the same time, the film layer can greatly improve the appearance of the workpiece.
Plating specifications: 1Mic16K gold ± 20% gold 2N18 color (no nickel 1Mic16 gold ± 20% gold 2N18 color)
Alloy: Nickel 5Mic copper + 5MicNi
Color: The electric gold is matched according to the requirements of the guests. The main electric 1N14, 2N18, the plating thickness and color requirements should be written when plating (the most basic), different plating requirements should be arranged according to their characteristics
K value: gold content / color 14K, 18K, 22K, 23K (usually 22K less), the higher K, the lower the gold layer change.
Swiss standard: 1Mic gold = 1Mic16K = 1Mic16/23K = 0.75Mic16K + 0.25Mic23K
Swiss gold: 1N14, 2N18
Similarities and differences between PVD coating and traditional chemical plating (water plating)
PVD coatings are similar to conventional electroless plating. Both are surface treatments. They cover the surface of another material in a certain way.
The difference between the two is that the PVD coating layer has a stronger bonding force with the surface of the workpiece, the hardness of the film layer is higher, the wear resistance and corrosion resistance are better, and the performance of the film layer is more stable, the PVD coating film does not produce Toxic or contaminated matter.
