You’ve read all about the advantages of PVD coating. You have an idea of what color you want for your final product and have determined that PVD can provide the finish you desire. Before signing on the dotted line, it’s important to know what types of material can be PVD coated. Based on the base material of your product, PVD may be a viable choice for metal finishing.
Base Materials for PVD Coating
Some base materials adhere better with the metal deposition than others. In order to achieve the most durable and most attractive metal finishing, it’s essential to choose the right process. Depending on the material, nickel or chrome electroplating may be required for the best outcome. Some materials take the PVD coating directly better than others.
- Titanium, Graphite, Stainless Steel – Can be coated without base layers
- Steel, Brass and Copper – Typically nickel/chromium electroplated before PVD processing for better corrosion resistance, but can be applied directly
- Plastics, Aluminum, Zinc Castings – Typically uses the Low Temperature Arc Vapor Deposition (LTAVD) process
PVD can be coated on most metals, though some materials require a base layer of nickel and chromium in order to improve corrosion resistance.
PVD coating is a versatile process that can be used on a variety of materials, including temperature-sensitive plastics. These types of materials use the LTAVD process, which uses a lower temperature PVD process to deposit metal coatings.
Because PVD coatings can be applied to a wide spectrum of substrates, or base materials, it continues to grow in popularity for metal finishing. Depending on the gasses added during the PVD process, different colors could be achieved. Choosing PVD coatings as your metal finishing doesn’t limit your color choice to metallic, which is attractive in many industries. PVD coating shines as a strong option for both functional and decorative metal finishes.
