  • Modelling of impact-abrasive wear of ceramic, metallic, and composite materials [Elektronski vir]
    Rahmani, Ramin ; Antonov, Maksim ; Kamboj, Nikhil
    The behaviour of materials was investigated using finite element modelling software (SOLIDWORKS and COMSOL). Three types of materials were studied: (1) ceramic (diamond), (2) metallic (titanium), and ... (3) composite (consisting of ceramic and metallic phases). Finite element modelling allows illustrating deformation and stressing the distribution of the test material during a single impact of the tribodevice with or without abrasive particles. The impact energy absorption was investigated. Real composite materials were produced by a combination of 3D printing (selective laser melting) of the lattice structure (Ti6Al4V) followed by addition of a hard ceramic phase with the help of the spark plasma sintering technique. The produced samples were tested by a laboratory impact-abrasive tribodevice. The results of modelling and laboratory testing were compared. The effect of modelling variables is illustrated. It is explained why composite materials showed better performance in impact-abrasive conditions and are suitable for tunnelling and mining applications
