Hardmetal Coating
« 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, …
Read more »What Are Conversion Coatings and How Do They Form?
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 …
Read more »Pickling and Passivation
« 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 …
Read more »Process Parameters in Surface Technology
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 …

Metalworking fluids are essential for surface processing. But what composition do they have? And which ingredients are used? Learn more. Fluid Composition Fundamentals When machining speeds were limited by muscle power, heat generation played only a minor role. When machines …
Read more »Cold Forming of Metal
Cold forming is a metalworking process where materials are shaped under significant compressive or tensile forces with or without minimal preheating. This distinguishes cold forming from hot forming, with the dividing line being the recrystallization temperature. Formation of Material Microstructure …
