“…Contrary to the behaviour of the fibre-reinforced composites that distinctly display the influence of fibre orientation on the mechanical properties of the base matrix, the particulate distribution in the present study does not reveal such significant effects of reinforcement orientation [42]. Furthermore, the presence of the Mg added through the master alloy was once again detected from the XRD peak analysis that revealed Mg preferentially aligned along the (020) plane.…”

“…The obtained values of hardness analysis also revealed acceptable levels of surface hardness necessary for its application as a brake pad material [52]. Even though the addition of SiC reinforcements beyond 7 wt% would surely elevate the surface hardness, the corresponding deterioration in tribological performance as suggested by similar studies Contrary to the behaviour of the fibre-reinforced composites that distinctly display the influence of fibre orientation on the mechanical properties of the base matrix, the particulate distribution in the present study does not reveal such significant effects of reinforcement orientation [42].

The wear debris from conventional brake pads is a growing source of environmental contamination that often leads to life-threatening diseases for human beings. Though the emerging organic brake pads show potential to serve as an eco-friendly alternative, their mechanical and tribological properties are not adequate to withstand the demands of high-wear resistance of a functioning braking system under regular use. Metal matrix composites have served as an optimal solution with minimal environmental pollution and appreciable physical properties. Owing to the popularity of aluminium metal matrix composites, the present study is based on the fabrication and characterization of SiC-reinforced LM6 alloy through stir casting methodologies for evaluating its worthiness in application as a brake pad material. Microstructural, compositional, and phase characterizations were executed through optical micrography, X-ray diffraction, and energy-dispersive X-ray spectroscopy analysis. Although mechanical properties were evaluated through surface hardness investigation, parallel thermal properties were estimated through thermal conductivity evaluation. Finally, the execution of tribological analysis and precise microstructural observations of wear track at ambient and elevated temperatures helped in establishing the datum that the fabricated metal matrix composite (MMC) is a reliable brake pad material alternative.

The isothermal and thermal cycling oxidation behaviour of a directionally solidified Ni-Al-Cr3C2 eutectic alloy at temperatures from 800" to 1200 OC in flowing air have been investigated using several physical techniques. A t all temperatures an initial, protective, external layer of a-A12 O3 develops on the alloy surface. However, this breaks down mechanically during thermal cycling, enabling a less protective Cr203-rich scale to form. decreases with increasing temperature, failing after between 30 min and 2 h at 1100" and 1200 "C. However, if platinum metal is introduced into the hot zone at these temperatures, this period is increased to about 48 h.Following formation of the external Cr2 O3 scale, internal oxide penetration into the alloy can be considerable, involving preferential oxide penetration down the alloy/carbide fibre interfaces. Thermal cycling does not influence markedly the oxidation behaviour, although it does result in formation of a greater quantity of nickel-rich oxide nodules on the scale surface following crack development in the Cr2 03-rich scale. This crack development is assisted by differential thermal contraction stresses.The time of retention of the a-A1203 layer at temperature
