Zinc dust

Zinc dust corrosion protection is an effective method of protecting metal surfaces from corrosion. With this type of corrosion protection, finely ground zinc dust is applied to the metal surface as a coating. This process is often used in industrial applications, particularly in the field of corrosion protection for steel structures.

The zinc dust forms a protective layer on the metal surface, which acts as a sacrificial layer. This means that in the event of damage or scratches in the coating, the zinc corrodes preferentially and protects the underlying metal. This sacrificial mechanism makes zinc dust corrosion protection particularly effective, as it extends the service life of the protected structures.

The use of zinc dust as corrosion protection has several advantages. Firstly, zinc provides a high level of corrosion protection by forming a stable zinc oxide layer on the surface. Secondly, the sacrificial anode ensures that the protected structure is protected from progressive corrosion. Thirdly, zinc is a widely available and cost-effective material.

Zinc dust corrosion protection is used in various industries, including construction, shipbuilding, bridge building, and in environments where the metal parts are exposed to strong environmental influences. Careful application and regular inspection are crucial to maintain the effectiveness of this corrosion protection method and to ensure the safety and longevity of the protected structures.
