DIN EN ISO 12944 "Paints and varnishes - Corrosion protection of steel structures by coating systems" standardises corrosion protection by organic wet coating systems on "black" and also on hot-dip galvanised steel (duplex systems). It has been completely updated.

Superheroes from films wear armour that protects them. A particularly effective protective layer that not only makes them appear more imposing, but also makes what lies beneath more resistant. At first glance, thermal spraying also offers just that.

KS Gleitlager GmbH from St. Leon-Rot has a new dry extraction system in use for the fettling and inspection sections of its steel/aluminium production. The aim was to replace the old wet separators with a powerful, operator- and maintenance-friendly new system.

Superhelden aus Filmen tragen einen Panzer, der sie schützt. Eine besonders effektive Schutzschicht, die sie nicht nur imposanter erscheinen lässt, sondern das, was darunter liegt, widerstandsfähiger macht. Auf den ersten Blick bietet auch das thermische Spritzen genau das.

Steel components near the sea must be highly resistant to damaging environmental influences. Humidity, salty air and evaporation of chemicals cause accelerated corrosion. A coating system against such aggressive conditions can significantly extend the service life of components.

With novel galvanic coatings, researchers want to make rolling bearings so robust against corrosion that housings and lubricants become superfluous. This could increase the energy efficiency of wind turbines by up to 30 percent.

Metallised plastic surfaces are becoming an increasingly sought-after field of application for PVD coating. Especially in automotive construction, this visually and technically high-quality design solution creates an attractive option. Compared to previous processes such as galvanisation, it also offers new functionalities and greater environmental benefits.

Those who generate their compressed air with oil-free compressors from Atlas Copco need have no fear of their products being contaminated with mineral oil. Because the group has the "Class 0" for high-purity compressed air and high-purity vacuum from TÜV in writing.

A manufacturer of zinc die-cast parts uses a novel nano-coating to coat components for the automotive industry. Tests show that this also offers a very good protective effect in terms of abrasion and corrosion compared to galvanic coatings.

The complete drying of large helicopter gearbox parts presented a drying system manufacturer with a completely new challenge. This was successfully solved with a combined blow-off/drying room variant.
