PVD Coating Services
What is PVD Coating?
PVD (Physical Vapor Deposition) is a process that forms a high-performance thin film on the surface of a material through physical methods such as evaporation or sputtering in a vacuum environment. This technique provides excellent properties including strong adhesion, high hardness, low friction coefficient, and outstanding wear and corrosion resistance.
Compared with traditional methods such as electroplating and painting, PVD stands out for its environmental friendliness (no liquid waste), thinner and more uniform coatings, and superior adhesion strength, making it a more advanced and sustainable surface treatment solution.
Advantages of PVD Coating
- ·High Hardness: Coating hardness can reach 2000–3500 HV (e.g., TiN coating reaches up to 2300 HV), effectively extending the service life of tools and components.
- Low Friction Coefficient: Reduces wear and improves efficiency (DLC coating as low as 0.05).
- High Temperature Resistance: TiAlN coatings can withstand temperatures up to 1000°C.
- Environmentally Friendly and Compliant: Free of chemical pollution, compliant with international environmental standards such as RoHS and REACH.
- Flexible Customization: Coating composition and thickness can be tailored to achieve various functions including wear resistance, corrosion protection, conductivity, and decoration.
- Strong Decorative Appeal: Offers a wide range of colors such as gold, black, silver, gray, and purple, with a refined appearance.
- Wide Applications: Compatible with various substrates including metals, ceramics, and plastics.
Available Types of PVD Coatings
| Coating Type | Color | Features | Applications |
| TiN (Titanium Nitride) | Gold | High wear resistance, versatile use | Cutting tools, molds, medical devices |
| TiCN (Titanium Carbonitride) | Gray-blue | Higher hardness, impact resistance | High-speed cutting tools |
| TiAlN (Titanium Aluminum Nitride) | Violet-black | Excellent high-temperature oxidation resistance | High-speed/dry cutting tools |
| CrN (Chromium Nitride) | Silver | Corrosion resistance, low friction | Precision molds, decorative parts |
| DLC (Diamond-Like Carbon) | Black | Ultra-low friction, exceptional wear resistance | Pistons, molds, precision bearings |

PVD Finishing FAQ
Q: Will the PVD coating peel off?
A: With ion bombardment pretreatment, the coating has strong adhesion to the substrate and is not prone to peeling under normal use.
Q: Is the PVD coating environmentally friendly?
A: No chemical solvents are used, and there is no wastewater discharge. It meets environmental protection requirements.
