TiC reinforced cast steel
metal matrix composites - Opis:
- Wear resistance of TiC-ZrO2-Fe locally reinforced steel casting has been investigated. Composites were obtained by introducing to mould cavity compact with TiC reaction substrates, ZrO2 particles and addition of moderator. Casting with local reinforcement – composite zone was obtained. Structure and microstructure of composite zone were investigated with use of X-ray diffraction (XRD) and scanning electron microscope (SEM) methods. The Miller slurry machine and Ball-on-Disc tester were used to determine wear resistance of the fabricated locally reinforced TiC-ZrO2-Fe composites. The worn surface of specimens after test, was studied by SEM. Due to the presence of TiC and ZrO2 particles in composite zone steel castings exhibited higher abrasion resistance than chromium white cast iron with Ni addition Ni-Hard 1 type and comparable with composites with high TiC content.
