Why do we use PVD to coat our coloured products?

All Radiant colour rails are PVD coated (except the matt black) PVD (Physical Vapor Deposition) coating and electroplating are two different processes used to apply a thin layer of material onto a surface. PVD coating has several advantages over electroplating, including:

  1. Improved Durability: PVD coatings are harder and more durable than electroplated coatings, making them more resistant to wear and corrosion.

  2. Uniform Coating Thickness: PVD coatings provide a more uniform thickness than electroplating, which can result in better overall coating performance.
  3. Environmentally Friendly: PVD coatings are more environmentally friendly than electroplating because they do not require the use of toxic chemicals.

  4. Versatility: PVD coatings can be applied to a wide range of materials, including metals, ceramics, plastics, and glass, whereas electroplating is limited to conductive surfaces.

  5. Enhanced Aesthetics: PVD coatings provide a range of attractive colors and finishes, making them ideal for decorative and architectural applications.

  6. Cost-Effective: While PVD coatings may have a higher upfront cost than electroplating, they can provide long-term cost savings due to their durability and low maintenance requirements.

Overall, PVD coating offers several advantages over electroplating, making it a popular choice for a wide range of applications, including automotive parts, aerospace components, medical implants, and architectural hardware.

Are there issues with heat conductivity through electroplating?
Yes, there can be issues with heat conductivity through electroplating. Electroplated coatings are typically thin and may not provide sufficient heat conductivity for certain applications. Additionally, the electroplating process can introduce thermal stress into the substrate, which can lead to cracking or other forms of damage when exposed to high temperatures.

In contrast, PVD coatings can provide excellent heat conductivity due to their higher density and uniformity, which can help dissipate heat more efficiently. PVD coatings can also be tailored to specific thermal conductivity requirements by selecting the appropriate coating material and deposition parameters.

Overall, the choice between electroplating and PVD coating depends on the specific application requirements and the desired properties of the coating. If heat conductivity is a critical factor, PVD coating may be a more suitable option than electroplating.
