Electrolytic Zinc Plating

Definition

Electrolytic zinc plating is an electrochemical process for applying a thin zinc coating to metal surfaces by immersing them in an electrolyte bath and applying electric current.

Types

There are different types of zinc plating, with electrolytic zinc plating being one of them. Other types include hot-dip galvanizing, strip galvanizing, and mechanical plating.

Materials

Electrolytic zinc plating is mainly applied to iron and steel products.

Applications

This process is widely used in industry, engineering, and craftsmanship. It is applied to screws, springs, switch plates, and other metal parts that require corrosion protection.

Maintenance and Care

Electrolytically zinc-plated surfaces generally do not require special maintenance. The zinc layer acts as a sacrificial coating and protects the base material from corrosion.

Standards and Certifications

DIN EN ISO 2081 specifies the requirements for electroplated zinc coatings on iron-based materials with additional treatment.
