Electrolytic zinc plating

A barrier against corrosion

Electrolytic zinc plating is the process of depositing zinc on a metal surface by electrolysis, often used to protect steel against corrosion. This technique creates a protective barrier against oxidation while maintaining excellent electrical conductivity.

Electrolytic zinc plating provides good corrosion protection with a low deposit thickness.

Blue passivation

Electrolytic zinc plating with blue passivation is a process whereby zinc is deposited on a metal substrate, followed by a bluish passivation. Passivation is an additional layer applied after zinc plating to improve corrosion protection and give an aesthetic blue appearance. This treatment is often used for applications requiring corrosion protection.

Black passivation

Electrolytic zinc plating with black passivation consists of electrolytic zinc deposition followed by black passivation, while offering protection against corrosion.

Yellow passivation

Electrolytic zinc plating with yellow passivation is a similar process, in which a layer of zinc is deposited by electrolysis, followed by an iridescent yellow passivation. This passivation improves corrosion resistance. It is often used in moderately corrosive environments where better protection is required than with blue passivation.
