Workshop at the learning camp of the Auerbach Goethe-Gymnasium
From 30 March to 1 April 2022, around 30 pupils took part in the learning camp at Goethe-Gymnasium Auerbach in the Vogtland region of Saxony. In one part of the workshop, scientists from the Chair of Materials and Surface Engineering supervised experiments on electrochemical and thermal oxide layer formation on titanium substrates under the topic „Highly Exciting and Blazing Hot“. The layer thicknesses of the coatings produced are in the order of magnitude of the wavelength of visible light and lead to different colour appearances due to interference effects.
The method is used for the decorative design of high-quality sports equipment and is used in medical technology to make implants stand out from body tissue in terms of colour. The students anodised IWW bookmarks and TUC emblems in citric acid before adding rainbow colours to the flames of a titanium kite over an open fire.
The IWW team has been involved in the Learning Camp workshop for many years in order to get young scientists interested in natural sciences and engineering at an early stage and to show them study opportunities at Chemnitz University of Technology.
