Oils and greases temporarily protect metal surfaces from corrosion during storage and processing. Long-term corrosion protection, however, is only achieved through surface technology. Specialized coatings act as barriers, preventing environmental factors from reaching the metal. The prerequisite is that surfaces …

The adhesion of coatings and the durability of adhesive bonds depend largely on the condition of the surfaces involved. Pre-treatment gives a material the surface characteristics necessary for successful downstream processing. Surface treatment uses various pre-treatment methods depending on the …

To develop effective methods for reducing friction-related losses of material and energy, it is necessary to develop a clear understanding of the mechanisms underlying friction and wear. In this context, the term “tribosystem” was introduced. The prefix ‘tribo-‘ derives from …

Bulk transportation of feed, chemicals, petroleum products, and foodstuffs often takes place in tank trucks. To ensure that goods arrive safely at their destination in top condition, thorough tank truck cleaning is essential — both at regular intervals and every …

Water beads up on many surfaces. After a rain shower, tiny droplets can still be seen on windows for a long time.  This occurs because thin water films contract into droplets. All these are effects of surface tension, which becomes …

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 …

« How to Identify Starting Points for Reducing Greenhouse Gas Emissions » Global warming is arguably the greatest threat of our time. Looking at prehistoric periods, we see that during every major climate shift, the species that went extinct were …

« 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 …
