Titanium nitride coating equipment is the core equipment of PVD technology.

It deposits a layer of high-performance TiN film on the surface of the workpiece by exciting the titanium source through arc, sputtering and other methods in a vacuum environment and reacting with nitrogen.

The most outstanding advantage of this technology is that it can significantly improve the surface hardness, wear resistance and corrosion resistance of the workpiece, and give it a signature golden color.

Therefore, it is most widely and successfully used in the four major fields of cutting tools, mold manufacturing, wear-resistant parts and high-end decorative coating.

It is one of the key surface treatment technologies for modern manufacturing to improve product quality, extend service life and increase added value.

Main characteristics of TiN coating:

High hardness:

High hardness significantly improves the wear resistance of the workpiece surface.

Low friction coefficient:

Reduces friction and wear.

Excellent chemical stability:

Corrosion and oxidation resistance

Beautiful golden color:

An important feature for decorative applications.

Good bonding:

Strong bonding with a variety of substrates (steel, carbide, copper alloy, etc.).

High temperature stability:

Stable performance in high temperature applications such as cutting.

Applications:

Titanium nitride vacuum coating technology is widely used in many industrial fields because of its excellent performance on the surface of workpieces:

Cutting tool industry
Cutting tools:

Drills, milling cutters, turning tools, hobs, taps, blades, etc.

Effects:

Greatly improves tool hardness, wear resistance, and red hardness (ability to maintain hardness at high temperatures), reduces friction and built-up edge, significantly extends tool life (usually 2-10 times), and improves machining efficiency and surface finish. The golden color also makes it easy to identify coated tools.

Mould industry
Injection mold:

core, cavity, ejector, slider, etc.

Stamping die:

punch, die, blank holder, etc.

Die casting mold:

core, cavity, ejector pin, etc.

Effects:

Improve the mold surface hardness, wear resistance, and anti-adhesion (prevent plastic or metal adhesion), reduce mold release force, reduce mold wear, abrasions and corrosion, extend mold service life, and improve product demoulding and surface quality.

Wear-resistant parts
Various precision mechanical parts subject to friction and wear, such as bearings, bushings, guide rails, sliders, gears, pump and valve parts, textile machinery parts, food machinery parts, etc.

Effects:

Enhance the wear resistance of parts surface, reduce maintenance frequency and extend the service life of equipment.

Decorative coating
Bathroom hardware:

faucets, shower heads, handles, towel racks, etc. (providing a durable, wear-resistant and corrosion-resistant golden appearance).

Door lock hardware:

Lock panels, handles, keys, etc.

Spectacle frames:

Frame, temples (gold decoration).

Watch:

Case, strap, buckle (gold).

Jewelry:

Necklaces, bracelets and other metal-based jewelry.

Effects:

Provides a luxurious, stable golden appearance with excellent wear resistance, corrosion resistance, anti-fingerprint and color retention, far exceeding traditional electroplated gold.

Functional Devices
Medical devices:

Surgical instruments (such as scissors, tweezers, orthopedic drills), implants (partial surface treatment, biocompatibility needs to be considered, TiN itself has good biocompatibility), etc.

Improve wear resistance and corrosion resistance, sometimes also used for marking or aesthetics.
