    the Mechanical, Tribological and Electrochemical Behavior of Boride-Hardened Spheroidal Graphite Cast Iron (SG)
    (Université Badji Mokhtar Annaba, 2025) CHARMATI, Djihad
    This study examines the influence of varying Fe2B layer thickness on the microstructure, mechanical properties,electrochemical, and tribological behavior of ductile and gray cast iron through boriding. Boronizing was conducted at 950°C for one and four hours using a B4C-Na2CO3 pack-boriding method. Advanced analytical techniques, including optical microscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Vickers microhardness testing, were employed to analyze microstructural changes and mechanical properties. To assess the effectiveness and durability of the treatment, adhesion tests, scratch tests, and Daimler-Benz Rockwell-C adhesion tests were conducted. Additionally, tribological testing under controlled conditions and electrochemical experiments were conducted to assess friction, wear characteristics, and corrosion resistance. This research aims to provide insights into boronizing processes to optimise the performance of cast iron components across industrial sectors, including automotive, shipbuilding, and agriculture. Furthermore, the research contributes to the broader understanding of material behavior in materials science.
