Tribological Response of SPS-Prepared Mg–Ti–Al2O3 Nanofibre–GNP Composites with a Graphite Surface Layer

Magnesium-based hybrid composites reinforced with Ti, graphene nanoplatelets (GNPs), and short Al2O3 nanofibres were investigated with respect to their microstructure, hardness and dry sliding tribological behaviour. Four materials were studied: M0 (100Mg), M1 (70Mg–30Ti), M2 (69Mg–30Ti–1GNPs) and M3 (63Mg–30Ti–6Al2O3n...

Wear Response of Carbide-Reinforced 1.75 mol% Y2O3-Stabilized ZrO2 Composites Under Dry Sliding Conditions

This study investigates the mechanical and tribological behavior of three composites with a ZrO2 matrix stabilized with 1.75 mol% Y2O3 and containing 1 wt.% Al2O3, reinforced with TiC (A), TiC + ZrC (B), and TiC + WC + Mo2C (C). The matrix powder was synthesized by chemical coprecipitation, and the composites were cons...
