TiN hard Coatings Machine With Excellent Corrosion Resistance

PVD thin film functional coating machine / PVD hard coatings Equipment on Tools

Hard coatings, formed by reactive Physical Vapor Deposition ( PVD) processes, based on plasma technology,are becoming widely used in the tool industries.
In order to get the most hard, tense, wear-and corrosion-resistant coating, the substrate temperature should be as high as possible, and concurrent bombardment by energetic atomic-sized particles ( Ion-plating ) during the reactive deposition should be used. For example, in coating hardened steel drills, the substrate is heated to 450℃ or so before deposition is started. This pre-heating can be done by ion bombardment, which also sputter cleans the surface, or by using other heating sources in the deposition chamber.
During the process of PVD hard coating for tools, it does not change the physical dimensions of the part significantly.
The plasma gas used for reactive deposition is a mixture of argon, nitrogen and ethyne. The composition of the coatings is varied by varying the gas mixture.

The most common vaporization sources for the ion plating of hard coatings are unbalanced-magnetron- -sputtering sources, and cathodic-arc-vaporization sources. Bombardment during deposition is commonly achieved by applying a negative bias (-200 to -300 volts ) to the substrate and accelerating positive ions to the surface from a plasma. A high ratio of bombarding ions to depositing atoms is important for densifying the depositing material. In the unbalanced-magnetron-sputtering source, few of the sputtered atoms are ionized; but in the cathodic arc sources, a high percentage of the vaporized atoms are ionized. Because these “ film ions ” have a higher mass than do the gas ions, they are better able to sputter surfaces and densify films by “ atomic peening.”

Industrial tool coatings are typically 1.5 to 4 microns in thickness.

Applications:

Hard coatings are becoming widely used in the decorative coating and industrial tools (HSS or HSC
materials). The coatings are more resistance to wear and corrosion, to fulfill the tools functions more reliably and for a longer life time, 2-3 times longer than without coating in general.
Cutting Tools: ( Suggested Coatings: AlTiN/TiAlN, TiCN and TiN)

Sawing, milling, CNC insert ( hard turning using), drilling, hobbing and gear cutter etc.

PVD (Physical Vapor Deposition) is a widely used and advanced surface treatment technology in the world at present. It can really get micrometer coating and pollution-free environmental surface treatment. In a vacuum state, the coating material is vaporized by ion physical method and deposited into a coating on the surface of the product.
PVD coating features:

(1) excellent adhesion: PVD coating has high adhesion and durability. It can be applied to bending at different angles without cracking or spalling. It can be used for inside and outside decorations.
(2) anti-oxidation, corrosion resistance: stable chemical properties, in the normal environment, indoor and outdoor can be antioxidant, not easy to fade, maintain metal glossiness.
(3) increase the surface hardness: the hardness of the film measured by Micro, up to HV2250
The type and thickness of the coating layer
(1) the species of the coating:
PVD coating technology can prepare nitride film (TiN[titanium gold), ZrN [zirconium gold], CrN, TiAlN] and carbide film (TiC, TiCN), and oxide film (TiO, etc.).
(2) the thickness of the film layer:
The thickness of the film is micrometer, and the thickness of the coating film is generally 0.3 u m~0.5 mu
