Dataset on contaminated steel/rubber contact: Effect of surface texture on friction coefficient

An experimental dataset on the friction behaviour of steel/rubber contact under contaminated conditions, obtained using a pin-on-disc tribometer is given. Additionally, the dataset provides detailed surface texture parameters derived from 3D surface mapping following ISO 25178 standards. These data can be used to analyse the influence of surface texture on frictional behaviour under degraded contact conditions, validate numerical friction models, and support the development of engineered surfaces for optimized tyre-rail interactions. The dataset is available in CSV format and can be accessed using any text editor or data analysis software. This data is related to the research article “Tyre/Rail Contact: An Experimental Investigation on Contaminated Contact Cases”, where the full experimental methodology is described.
