Coating equipment nanometer technology coating for hard cutting tool coating material

    With the development of nanotechnology and coating technology, the research of nano coating materials also caused the attention of the tool. There are two kinds of nano coatings: nano multilayer structure and nano composite structure. Nanostructured multilayer coatings generally by the high number of conspecific material structure, chemical bond and atomic radius and lattice often similar monolayer material composition, may be obtained with the monolayer coating performance differed significantly with the new coating composition. This is a man-made one-dimensional periodic structure, alternating deposition of a single layer of coating is not more than 5 ~ 15nm. Chu and Barnett believe that the high hardness of the nano multilayer coatings is mainly due to the difficulty of the movement of the internal and inter layer dislocations. When the coating is very thin, the shear modulus between the two layers of different, if interlayer dislocation energy has a larger difference, the interlayer dislocation movement difficulties, ascended the throne for dislocation motion energy determines the hardness of the superlattice coatings.

There are three kinds of nano multilayer coating structure:

(1) metal nitride nano layer and metal AlN nano layer alternately coating;

(2) metal AlN nano layer and metal AlCN nano layer alternately coating;

(3) metal nitride nano layer and metal AlN nano layer and metal AlCN nano layer alternately coating.

Coating process can be added to other metal elements (such as Ti, Nb, HF, V, Ta, Zr or chromium), to further improve the coating equipment coating hardness, chemical stability, toughness and antioxidant properties. Studies have shown that for tin / AlN nano coating. When the layer thickness of 2 to 4 nm, AlN has a cubic NaCl structure, coating microhardness reached 30 ~ 40 GPA, the oxidation temperature reaches 100 DEG C, by plasma enhanced chemical vapor deposition was the AlN/TiAlN nano multilayer film has high hardness, high adhesion and high wear resistance of.

Although most of these nanostructured coatings are the results of the laboratory, the results show that the nanostructured coatings have good prospects in metal cutting. Huicheng vacuum R & D super hard coating solution scheme of equipment including tooling superhard ion plating machine and hollow cathode ion plating equipment, these two devices is designed for coating super hard films and R & D for in molds, tools, cutting tools, and other industries, the surface more durable, more anti corrosive coating, increase the service life of the cutter is 3 ~ 10 times, enhance the service life of the die is 5 ~ 10 times.

Plating materials: TiN, TiC, TiCN, TiAlN, TiAlCN, TiCrN, TiCrCN, TiAlCrN, ZrN, CrN, DLC, multi layer, such as epidural.

PVD coatings provide excellent adhesion, hardness and wear resistance to your tools and components, including: TiN, CrN, ZrN, and AlTiN. If your application needs, we can also provide a multilayer coating such as TiCN.
