PVD (Physical Vapor Deposition) coating is a versatile process that can be applied to a wide range of metals and alloys. This coating enhances the durability, performance, and aesthetic appeal of the materials. Here’s a detailed look at the five key types of metals that can be PVD coated.
1. Steel and Alloys
High-alloy steels, including high-speed steels and stainless steels, are particularly suitable for PVD coating. These materials benefit from the enhanced durability and performance that PVD coatings provide. The process involves depositing a thin film of material onto the surface, which can improve the metal’s resistance to wear and corrosion.
2. Non-Ferrous Metals and Alloys
Metals such as copper and aluminum, along with their alloys like brass, are also commonly coated using PVD. These materials can be given a range of finishes and colors through PVD, from 24K gold to dark brass, enhancing their aesthetic appeal and functionality. However, brass without galvanization or galvanized materials are problematic in PVD processes due to the volatility of elements like zinc and lead in vacuum conditions.
3. Plated Metals
Metals that are already plated with chrome or nickel are also candidates for PVD coating. These pre-plated surfaces can be further enhanced with PVD to add additional layers of protection or to alter the surface properties, such as improving hardness or reducing friction.
4. Preparation and Considerations
For effective PVD coating, the substrate must be vacuum-compatible. This often involves pre-treating the materials, such as applying organic coatings or electroplating with nickel and chromium. The PVD process itself does not alter the surface roughness significantly, meaning that any existing surface imperfections will remain visible after coating. However, a polymer powder coating can be used as a pretreatment to mask these imperfections and provide a smoother finish.
5. Common PVD Processes
The most common PVD processes include Electron Beam Evaporation and Ion Plating. Ion Plating, in particular, is valued for its ability to produce uniform and consistent coatings, which is crucial for applications requiring high precision and reliability.
In summary, PVD coating is a versatile process that can be applied to a wide range of metals and alloys, enhancing their properties and extending their lifespan. However, careful consideration must be given to the material’s compatibility with vacuum conditions and the potential for volatile elements to interfere with the coating process.
