Forming & Protection

Wherever the word “duplex” appears, it usually refers to something double-layered. In surface technology, duplex systems are no exception—they consist of two protective layers to defend against corrosion. The bottom layer is created through hot-dip galvanizing, while the top layer …

« A Brief Overview of the process » Anodizing is a process that provides aluminum semi-finished products (partially processed materials) or workpieces with a corrosion-resistant and wear-resistant surface. This protective layer is formed with the aid of an electric current …

« How to Manage Paint Systems Effectively » The paints used in surface technology change their physical state during processing. The raw materials are in liquid form or are at least flowable so that they can completely cover the surface. …

Electroplating is a process in which electric current causes metals to deposit uniformly on the surface of workpieces. The metallic layer primarily serves to protect against corrosion, resist mechanical wear, or improve electrical conductivity. Additionally, electroplating may aim to achieve …

« What influences the paint quality » In surface treatment, paints and coatings are applied to components to protect them from environmental damage, enhance their appearance, or modify surface properties. Paint ingredients form a complex system tailored to the intended …

Chromates, which are chemical salts derived from chromic acid, play a role in two distinct surface treatment processes: Chromating, where chromic acid or its salts create a chromate layer on a material’s surface. Chromium plating, where dissolved chromates (electrolytes containing …

« Which Painting Option is Recommended? » Both powder coating and liquid paint are widely used in surface coating. The decision between the two depends mainly on factors such as the material, contour, and size of the parts to be …

« Your Options for Surface Coating » The term hardmetal coating can refer to two different processes: applying a hardmetal layer to conventional metals, or enhancing existing hardmetal components with highly wear-resistant materials. These composites consist of a metallic binder, …

Conversion means transformation. A conversion coating, by definition, is simply a transformed layer. But what exactly is being transformed—and how? Let us take a closer look. What Exactly Is a Conversion Coating? In surface treatment, a conversion coating refers to …

The Eiffel Tower is the symbol of Paris. Around 130 years ago, this steel structure was completed just in time for the World’s Fair and has lost none of its fascination to this day. More than 7 million visitors tour …
