Nitrocarburized Components Part 3: In-situ tool for assessing mechanical performance (KvantNit3)

Purpose and goal

The purpose of the research project is to build on our previous pilot project where the micromechanics of nitrocarburized steel components were evaluated using nanoindentation at the P03 beamline at Petra III. In addition, we will try a new measurement setup at P21.2, which can later be developed into an in-situ measurement of wear performance. Both methods have industrial relevance and potential to offer unmatched quality at a justified cost and lead time. The objective is that the industrial partners will have access to these tools for their development work.

Expected effects and result

Synchrotron-based experimental in-situ tools would enable tailoring of the complex surface microstructure of nitrocarburized steel components to a given application for optimal performance. It thus has an effect on the industry´s innovative capacity and resource efficiency and responds to the need to use more environmentally friendly processes for surface improvement. For example, our industrial partners confirm that nitrocarburizing has potential to replace expensive and non-environmentally friendly production processes, such as hard chrome and phosphating.

Planned approach and implementation

The project consortium includes RISE, KTH, Swerim, Bodycote and Volvo Lastvagnar. The industrial parties will, via nitrocarburization, produce relevant samples that will be characterized using standard lab-methods. The academy proceeds with more advanced characterization before samples are manufactured for in-situ measurements at Petra III. Industry partners will participate at the synchrotron to gain knowledge on characterization techniques to may clarify the link between microstructure and performance of nitrocarburized parts.
