Product Description
Customized PVD Coating Service Technical Solution and Core Advantages of Fuzhou Jiahexing
1. Overview of PVD Coating Technology
PVD (Physical Vapor Deposition) coating is an advanced surface treatment technology that deposits thin films on the substrate surface through physical methods in a vacuum environment, featuring the following characteristics:
Technical Advantages:
- Film thickness 1-10μm, does not affect the dimensional accuracy of the workpiece
- Hardness up to HV2000-4000 (3-5 times the hardness of the substrate)
- Operating temperature tolerance: 300-800℃ (depending on coating type)
- Environmentally friendly and pollution-free, compliant with RoHS/REACH standards
Technical Limitations:
- Difficult to control uniformity of coating in deep holes/complex internal cavities
- Deposition stress impact must be considered for high-precision parts
- High equipment investment, cost advantage not obvious for small batches
2. Jiahexing PVD Service Technical Parameters
| Coating Type | Hardness (HV) | Coefficient of Friction | Temperature Resistance (℃) | Typical Applications |
|---|---|---|---|---|
| TiN (Titanium Nitride) | 2300-2500 | 0.4-0.6 | 600 | Cutting tools, molds |
| CrN (Chromium Nitride) | 1800-2200 | 0.3-0.5 | 700 | Plastic molds, food machinery |
| TiAlN (Titanium Aluminum Nitride) | 3000-3500 | 0.2-0.4 | 800 | High-speed cutting tools |
| DLC (Diamond-Like Carbon) | 1500-4000 | 0.05-0.15 | 300 | Medical devices, automotive parts |
3. Comparison of Jiahexing Technical Advantages
