Corrosion protection | Galvano Hengelo

Corrosion protection

Many metals are prone to corrosion. Good corrosion protection helps extend the service life of metal objects and components. It also ensures a neat and presentable appearance.


What is corrosion?

Corrosion is (chemical or electrochemical) degradation of a metal that occurs when it is exposed to adverse conditions (moisture and salts). This results in corrosion products such as metal oxides. The rusting of iron is a good example.


Which corrosion protection treatments are available?

Corrosion is not always desirable. Corrosion protection slows down the natural process as much as possible. Galvano Hengelo has various treatments for improving the anti-corrosion properties of metal. For example:


Protalloy® (zinc nickel)

Zinc-nickel electroplating provides excellent corrosion resistance on cast iron and steel. Galvano Hengelo is highly specialised in zinc-nickel electroplating. At least 1,000 hours of salt spray protection (NSS) can be achieved by applying an extremely thin coating of just 5 mμ. Zinc-nickel electroplating is mainly used in hydraulic power transmission technology: manifolds, control valves and cylinders. Other sectors include machine and equipment construction, energy engineering and automotive industries.

Tin electroplating

We apply tin plating as a contact material within the electrical engineering and electronics industry. Tin not only provides good solderability and ductility, but also corrosion protection on contacts and components. Tin plating provides particularly good corrosion protection on copper (alloys). The copper maintains the high electrical properties and solderability.

Electroless nickel plating

Electroless nickel plating is a suitable method of surface treatment for products with complex shapes or a product that requires extremely accurate coating thickness. We apply electroless nickel plating to make your product or semi-finished product corrosion resistant. We nickel-plate both steel and cast iron (depending on the porosity), as well as aluminium.
