Helmut Fischer GmbH has been developing and manufacturing high-precision measuring instruments for coating thickness measurement, materials analysis, materials testing and microhardness for industry and laboratories since 1953. With its broad product portfolio, the Sindelfingen-based company group is one of the world's technology leaders. The FISCHERSCOPE® HM 2000 hardness tester has been used successfully in teaching and research for many years and determines quantities such as indentation hardness and elastic modulus in a depth-dependent manner - and in the nanometer range.
The students and researchers of materials engineering at the Ernst-Abbe-Hochschule Jena University of Applied Sciencescan now look forward to a new measuring device from Helmut Fischer: represented by Mr. Wladislaw Feuchtenberger, Fischer handed over the scratch tester FISCHERSCOPE® ST 200 to its future purpose at the EAH Jena on November 15, 2021. Mr. Feuchtenberger himself is a graduate of materials engineering at EAH Jena and is now responsible for application technology in the fields of nanoindentation and scratch testing at Fischer.
In scratch testing, a Rockwell diamond syringe is drawn over the surface of a sample at a constant speed and with a defined normal force. The resulting scratch provides information on how the material or coating will behave under mechanical stress in real life. In industry and research, for example, the cohesion and adhesion properties of coatings are tested and specifically further developed in this way.
Prof. Maik Kunert, who works in the "SciTec - Precision Optical Materials" department took delivery of the new device. It will be used in teaching and research in the future. Initial ideas for its use in research already exist: For example, models are to be developed for the quantitative description of the abrasive wear of modern highly wear-resistant TRIP steels.
