Special Issue Information

Dear Colleagues,

Fe-based materials are widely utilized in various fields, including engineering machinery, mining and crushing, thermal power generation, cement building materials, and railways. In these applications, wear failure is frequently observed, highlighting the importance of enhancing wear resistance due to its significant economic and industrial value.

Wear-resistant iron-based materials are currently being developed by increasing hardness, introducing hard particles or carbides, and reducing friction coefficients through the incorporation of lubricating materials or external lubrication. Utilizing high-resistance iron-based materials in mechanical components can significantly extend their service life.

This Special Issue focuses on enhancing the wear performance of iron-based materials through composition optimization, advanced preparation techniques, and lubricating phase incorporation. A thorough investigation of Fe-based materials' tribological behavior under diverse wear conditions is essential for improving wear resistance. This Special Issue aims to provide practical insights for engineers developing high-performance, wear-resistant iron-based materials.

The tribological behavior of ferritic ductile iron without ultrafine graphite nodules (FDI) and ferritic ductile iron with ultrafine graphite nodules (FDI-UG) was investigated in the present study. Ultrafine graphite nodules with a count of 3400 nod/mm2 were introduced by annealing treatment of quenched ductile iron, which effectively reduced the friction coefficient of ferritic ductile iron from approximately 0.3 to 0.15. This improvement was attributed to the ultrafine graphite nodules, which, due to their small spacing, facilitated a more uniform distribution on the tribological surface. Additionally, the formation of ultrafine graphite nodules in ferritized ductile iron refined the grain size (15 μm) and enhanced the hardness of ferritic ductile iron (183 HV), thereby significantly reducing abrasive wear. The more uniform graphite lubrication on the tribosurface and high hardness of fine ferrite grains in FDI-UG further enhanced wear resistance between the frictional pairs, effectively suppressing adhesion wear at high loads (6 N). Consequently, the ferritic ductile iron containing ultrafine graphite nodules and fine ferrite grains exhibited a superior wear resistance (6.84 × 10−3 mm3 and 9.47 × 10−3 mm3) compared to its untreated counterpart (9.22 × 10−3 mm3 and 11.95 × 10−3 mm3). These findings suggest that the incorporation of ultrafine graphite nodules was an effective strategy to enhance the tribological properties of ductile iron. Full article
