Ten Problems in PVD Coating Processing (Part 2)

6: What are the characteristics of the film-coated by PVD coating technology?

Answer: The film-coated by PVD coating technology has the characteristics of high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the life of the film is longer; at the same time, the film can Greatly improve the appearance and decoration performance of the workpiece.

7: What substrates can PVD be plated on?

Answer: PVD film can be directly plated on stainless steel, cemented carbide, titanium alloy, ceramics and other surfaces. For zinc alloy, copper, iron and other die castings, electroless chromium plating should be performed first, and then PVD plating is suitable.

8: What types of films can be produced by PVD coating?

Answer: PVD coating technology is an environmentally friendly surface treatment method that can truly obtain micron-scale coatings without pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN[[ Titanium Gold], ZrN [Zirconium Gold], CrN, TiAlN) and carbide films (TiC, TiCN), and oxide films (such as TiO, etc.).

9: What is the thickness of the PVD coating film?

Answer: The thickness of the PVD coating layer is micron, and the thickness is relatively thin, generally 0.1μm ~ 5μm, and the thickness of the decorative coating layer is generally 0.1μm ~ 2μm, so it can be improved without affecting the original size of the workpiece. Various physical and chemical properties of the surface of the workpiece, and can maintain the size of the workpiece basically unchanged, and no further processing is required after plating.

10: What are the colors of the film that can be plated by PVD coating?

A: The colors of the film we can make at present include deep golden yellow, light golden yellow, brown, bronze, gray, black, gray-black, seven colors, blue, purple, red, green, etc. By controlling the relevant parameters in the coating process, the plated color can be controlled; after the coating is completed, the color value can be measured with the relevant instrument, so that the color can be quantified to determine whether the plated color meets the requirements.
