Abstract:
The aim of this study was to evaluate the microstructure and tribological properties of an iron–cast iron–glass (Fe–CI–Glass) composite produced by conventional powder metallurgy and to determine its optimum composition. The composite was fabricated from SLM-12 iron powder, gray cast iron powder, and C88 vacuum glass powder by mixing, compaction, and sintering. The component proportions were varied according to the experimental design. The effects of oxidation, compaction pressure, and glass content on the microstructure and tribological behavior were investigated. Oxidation at 200 °C for 1 h produced a more homogeneous microstructure and stronger bonding between the metallic and glass phases. Tribological tests conducted under a load of 4 MPa and a sliding speed of 1 m/s showed low friction and wear. Graphite in the gray cast iron acted as a solid lubricant, while the glass phase partially filled pores and improved structural homogeneity. Fuzzy Logic and Fuzzy C-Means modeling identified the optimum composition as 52 wt.% Fe, 42 wt.% gray cast iron, and 6 wt.% glass. The results indicate that the investigated composite may be suitable for antifriction applications under the studied conditions.
