Thank you for visiting the DZ SAFETY equipment blog. We take pride in supporting companies with relevant industry information, so sometimes we cover topics outside of our services and capabilities. While surface treatments are necessary processes for virtually every system we manufacture, DZ SAFETY does not provide surface treatments as a standalone service.
Common Metal Surface Finishing Techniques Used In Height Safety Equipment Accessories
No matter what the reason, each of these three metal surface finishing processes plays an important role in the custom machinery manufacturing process:
1.Electroplating – This process forms a thin metallic coating on the substrate. The electroplating process passes a positively-charged electrical current through a solution containing dissolved metal ions and a negatively charged electrical current through the metallic part to be plated. Common metals utilized for electroplating are cadmium, chromium, copper, gold, nickel, silver, tin, and zinc. Almost any base metal that conducts electricity can be electroplated to enhance its performance.
2.Anodic Oxidation – This type of surface treatment is typically used for light metals, such as aluminum and titanium. These oxide films are formed by electrolysis, and since they are porous, dyeing and coloring agents are frequently specified for an improved aesthetic appearance. Anodization is a very common surface treatment that prevents corrosion on aluminum parts. If wear resistance is also desirable, engineers can specify a version of this method that forms a relatively thick, extremely hard, ceramic coating on the surface of the part.
3.Hot Dipping – This metal surface treatment requires the part to be dipped into dissolved tin, lead, zinc, aluminum, or solder to form a surface metallic film. Hot-dip galvanizing is the process of dipping steel into a vessel containing molten zinc. Used for corrosion resistance in extreme environments, Height Safety Harness Hardware are commonly processed with this surface treatment.
