Freisinger, M., Rodríguez Ripoll, M., & Hahn, R. (2024). Unveiling the mechanical properties of near-surface microstructures in tribological contacts via in-situ micro-bending tests. Tribology International, 191, Article 109190. https://doi.org/10.1016/j.triboint.2023.109190
This study demonstrates the application of the in-situ V-notched micro-cantilever bending method in tribology by analyzing three distinct cases of near-surface microstructures occurring in common tribological contacts. The brown etching layer region of a rail wheel from service shows predominant plastic material behavior. Significant variations in material response and crack initiation are revealed in distinctive regions of a roller bearing's near-surface microstructure and a self-lubricating laser cladding. Qualitative analysis and stress-displacement graphs highlight the method's potential for gaining high-resolution insights into material behavior, contributing to our understanding of microstructural changes affecting friction, wear, and component failure in tribosystems.
