When it comes to coating technologies, CVD (Chemical Vapor Deposition) and PVD (Physical Vapor Deposition) are two of the most popular methods.
4 Key Differences Explained
1. Material Versatility and Purity
CVD offers high purity and a wide selection of materials in various compositions and forms.
This versatility makes CVD suitable for different microstructures such as monocrystalline, polycrystalline, and amorphous.
CVD is particularly useful in applications like biomedical device implants, circuit boards, and durable lubricious coatings.
2. Process Control and Customization
CVD operates in several categories including atmospheric pressure CVD, low-pressure CVD, and ultra-high vacuum CVD.
Low-pressure and ultra-high vacuum CVD are the most common methods, allowing for precise control over the deposition process.
CVD processes like aerosol-assisted CVD, direct liquid injection CVD, and plasma-enhanced CVD provide further customization options based on substrate heating, material properties, and types of plasma used.
3. Substrate Preparation and Coating Thickness
Unlike PVD, CVD does not require stringent cleaning of the substrate before deposition.
This reduces process complexity and potential contamination risks.
CVD films are typically thicker (5-10 microns) compared to PVD coatings (2-5 microns), which can be advantageous in applications requiring thicker layers.
4. Drawbacks and Safety Considerations
While CVD offers many advantages, it also has some drawbacks compared to PVD.
CVD may have lower wear resistance, adhesion, and corrosion resistance.
The handling and storage of some CVD precursors and by-products can pose safety issues due to their toxicity, pyrophoric nature, or corrosiveness.
