For more than a year now, scientific congresses, trade fairs and discussion forums have had to be cancelled or moved to a restrictive digital format due to the pandemic. In order to reinvigorate regular exchange within materials, process and manufacturing engineering and to highlight current research topics, Leibniz-IWT is now setting up a new, free online format: "Leibniz-IWT live".
Here, experienced employees of Leibniz-IWT report on their current research activities up to four times a year. Following the 30-minute lecture, the same amount of time is allotted for follow-up questions and lively discussion, in which everyone is cordially invited to participate. The new lecture series is aimed at all interested parties from science and practice, regardless of whether they are already familiar with the IWT or are just getting to know it. The four annual lectures in this series of events cover a wide range of topics and projects and demonstrate the breadth of materials-oriented research.
For the last time this year, on December 2nd at 4 p.m., we will say: welcome to "Leibniz-IWT live"! And we are looking forward to seeing you again there.
Bastian Lenz will give a presentation on the topic "Application of deep learning image recognition techniques for characterization of thin coatings".
The presentation will again be digital via Webex.
Characterization methods are an important part of surface engineering and coating development. By using deep learning image classification and object detection techniques, some of them can be automatized to meet the latest digitalization demands.
The Rockwell-C and the Scratch-test are established methods for coating adhesion determination. Since they are based on the classification of light microscopic images, it is possible to substitute humans with trained special neuronal networks, the convolutional neural networks. These so-called CNN's are already being used successfully in a variety of other applications, and can be adapted for material science purposes.
As an extension of Vickers hardness testing, the Palmqvist method utilises crack formation at the edges of Vickers indentations to evaluate the fracture toughness of bulk materials and coatings. By using CNN-based object detection, the necessary indentation and crack size measurement can be automatized.

Leibniz-IWT live logo You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
