Use of Angle-Resolved Light Scattering, X-Ray Fluorescence Spectroscopy and Eddy Current Conductivity Measurements for Surface Condition Monitoring in a Mechanochemical Surface Finishing Process

摘要

Extensive research over a few past years proved significant potential of mechanochemical surface finishing for improving the tribological properties of mechanical components made of steel or cast iron. Over this time, a variant of mechanochemical finishing process, known as Triboconditioning, has gained particularly large industrial interest, making a rapid progress from basic laboratory experiments to fully-fledged production trials. Industrial acceptance of the Triboconditioning process depends heavily upon availability of technically robust and cost-effective quality control tools for surface condition monitoring during and after the Triboconditioning treatment, with the major emphasis being made on geometrical product specifications (GPS) and surface chemistry. The present communication outlines scientific principles and demonstrates technical possibilities of three different surface condition monitoring techniques suitable for industrial use. Tribofilm build-up kinetics, time-evolution of surface roughness profiles during the treatment, and correlation between variance of angular distribution of scattered light (Aq-value) and traditional ISO 4287 and ISO 25178 surface roughness parameters are investigated.
