Zinc Trivalent Black Plating

Zinc Trivalent Black Plating – Lotus Technologies

Zinc Trivalent Black Plating is a corrosion-protective coating process where a zinc layer is electroplated on metal components, followed by a trivalent black passivation treatment. This creates a black finish on the surface with enhanced corrosion resistance.

Key Benefits of Zinc Trivalent Black Plating

• Excellent Corrosion Resistance
  Protects steel/iron parts from rust and oxidation.

• Premium Black Finish
  Provides uniform black surface appearance for industrial and functional components.

• Durable & Long-Lasting Coating
  Improves component life in demanding environments.

• Good Surface Uniformity
  Ensures smooth and consistent plating output.

• Suitable for Industrial Usage
  Ideal for components exposed to moisture, heat and industrial conditions.

• Environment-Friendly Process
  Trivalent passivation is safer and more compliant compared to traditional hexavalent methods.

Applications of Zinc Trivalent Black Plating

• Fasteners
  Nuts, bolts, washers, screws.

• Automotive / Mechanical Parts
  Brackets, clamps, mounts, small metal parts.
