Zinc

Zinc plays an important role in surface technology due to its wide range of applications and its advantageous properties such as corrosion resistance, ductility and aesthetics. In various industries, zinc is used for coatings and surface treatments to extend the service life of components and improve their aesthetic appearance.

A common application of zinc in surface engineering is galvanizing, where a metallic zinc coating is applied to the surface of a substrate to protect it from corrosion. This coating method is often used on steel structures, fittings, vehicle parts and other metallic components that are exposed to an increased risk of corrosion.

Zinc coatings provide effective protection against atmospheric corrosion by acting as a barrier and protecting the underlying substrate from moisture, salts and other environmental influences. Furthermore, zinc can even provide an additional layer of protection through its sacrificial anode effect, sacrificing itself to protect the underlying material.

Another important application of zinc in surface technology is the use of zinc alloys or zinc compounds as additives in coating materials such as paints, varnishes and anti-corrosion agents. These materials can contain zinc to improve the corrosion resistance, adhesion and durability of the coatings.

Zinc is also used in electroplating, where it serves as a base for the deposition of other metals such as nickel or chromium. These electroplated coatings are often used in the automotive industry, electronics and decorative applications to meet aesthetic and functional requirements.

Overall, zinc is a versatile material in surface technology that helps to improve the corrosion resistance, durability and aesthetics of surfaces. The targeted application of zinc coatings and materials can improve the service life and performance of components and products in various industrial applications.
