Forming & Protection

« 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 …

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 …

« Why Heat Resistance Is a Critical Property in Surface Technology » In many industrial facilities, the surfaces of reactors, furnaces, and chemical plants must endure high temperatures and frequent thermal cycling. Lubricants used during machining face similar demands, where …

« What does it mean? » Pickling and passivation are chemical or electrochemical surface treatment processes that deliberately modify the properties of the material’s surface layers. These methods are commonly used in the pretreatment of metal workpieces to create corrosion …

Process parameters in surface technology are measurement variables that define the conditions influencing coating or material treatment procedures. Chemical and physical processes are triggered when an external influence disturbs the existing equilibrium. As the system seeks to re-establish balance, other …
