PVD Coatings on Medical Instrument Industry Application
- Bio-compatible Medical PVD Coating
Experienced surface treatment and PVD coater for medical instruments, orthopedics, probes, alignment devices, implants and surgical cutting tools. Coatings are bio-compatible and acceptable for use with external and internal devices that come in contact with skin, tissue, bone and blood.
- Coating Properties
- Improved wear resistance
- Reduced friction
- Bio-compatibility
- Decorative colors & aesthetic
- Chemical barrier
- Nickel Sensitivity
- Saline Solutions
- Sterilization
- Bio-compatible Coating Films
TiN and ZrN family of gold thin coatings for specialized medical devices and instruments.
TiAlN, AlTiN, AlTiSiN, CrN, TiCN, ALCrN family of medical coatings for cutting tools and specialized applications.
DLC coatings on the medical equipment for a very low co-efficiant of friction.
( a-C:H DLC):

| 1 | TiN | Gold | 2300-2500 | 0.35 | Pass |
| 2 | CrN | Silver | 2000-2200 | 0.35 | Pass |
| 3 | TiN/TiCN | Bronze/Gray | 2800-3200 | 0.3 | Pass |
| 4 | AlTiN | Violet/Black | 3000-3400 | 0.35 | Pass |
| 5 | TiAlN | Copper/Bronze | 3000-3200 | 0.4 | Pass |
| 6 | ZrN | Pale Gold | 2300-2500 | 0.35 | Pass |
| 7 | DLC (a-C:H) | Black | 2000-3000 | 0.1 | Pass |
| 8 | AlTiCN | Black | 1200-1800 | 0.2 | Pass |
| 9 | AlTiN | Black | 1200-2000 | 0.2 |
- Note:
The data generated from laboratory samples. Coating films properties may vary depending on customer’s material, surface condition ( high polished or others) and products 3D geometry.
TiN coating
Titanium nitride (TiN) coating is clinically being used on orthopedic implants for hip, knee, shoulder and ankle replacements as well as dental implants, brain and ear implants etc. Bio-compatibility: non-toxic.
Advantages
- Improved instrument performance
- Create distinct color identification, improve your product competition from others.
- Decrease friction and improve wear resistance: for example 0.35 VS 0.7 for un-coated steel.
- Oxidation and Corrosion Resistance
- Barrier layer for various solutions and environmental exposures.
PVD Coating Machine Models
