... performed. A maximum hardness of 133.3 HV was obtained at the top layer of the FGM. Pin-on-disc wear apparatus was used to evaluate the wear-rate and the coefficient of friction (COF) of the sintered specimen at varied loads. Specimens exhibited a low wear-rate of 2.36 × 10 −7 g/N m with 0.48 as the COF...

...Partha Haldar; Tapas Kumar Bhattacharya; Nipu Modak The study emphasized the sintering behavior and tribo-mechanical properties of alumina ceramics by nano-TiO 2 addition as a sintering aid. With increase in sintering temperature, the bulk density of alumina has increased gradually and optimized...

...Iftikhar Ahmad; Saqib Anwar; Fang Xu; Yanqiu Zhu We investigated the wear resistance properties of high-frequency induction heat (HFIH) sintered alumina (Al 2 O 3 ) ceramic nanocomposites containing various multilayer graphene (MLG) concentrations. The tribology of the monolithic Al 2 O 3...

...Ozgen Akalin; K. Vefa Ezirmik; Mustafa Urgen; Golam M. Newaz Wear characteristics of Al6061 composites, reinforced with short NiTi fibers, were investigated. The NiTi/Al6061 composite samples were fabricated using pressure-assisted sintering process in ambient air where the NiTi fibers are aligned...
