Holger Schnarr born in Thuringia in 1965. After completing his apprenticeship at a nuclear power plant and his military service, he studied materials engineering at Otto von Guericke University in Magdeburg. In 1995, he completed his doctorate at the Fraunhofer Institute for Mechanics of Materials in Halle/S. After working in various branches of industry, he joined Struers GmbH in Willich as laboratory manager in 2004. He is head of the working group “Sample Preparation” of the DGM since 2007.
Abstract
The article describes various modifications of Klemm etching solutions and their applications to different materials. In addition to classic immersion etching, electrolytic etching is also used for the first time, demonstrating the potential of this etching method based on sodium thiosulfate and potassium metabisulfide for other materials.
Kurzfassung
Im Beitrag werden verschiedene Modifikationen von Klemm-Ätzlösungen und ihre Anwendungen auf unterschiedliche Werkstoffe beschrieben. Neben den klassischen Tauchätzungen werden erstmalig auch elektrolytische Ätzungen eingesetzt, die das Potential dieser Ätzung auf Basis Natriumthioslufat und Kaliummetabisulfid für weitere Werkstoffe zeigen.
