“…et al [20] analysed the microstructure nature of the Al-SiC composites; they found that while adding reinforcement to the matrix, big pores were found, due to the low volume fraction and grain size of the reinforcement added to the composites [21]. The particles are in heterogeneous distribution and are so large that the worn surface can be seen; the durable bonding between the reinforcement and matrix resulted in particle accumulation and grain boundaries [22] and [23].…”

Cu matrix composites benefit from the high electrical and thermal conductivities of Cu and the mechanical wear/erosion resistance of hard reinforcement. In this study, an attempt has been made to determine the effect of the addition of reinforcement B4C in Cu-Ni-Sn. The B4C is reinforced to form a hybrid Cu matrix composite with powder metallurgy technique. The hybrid composites are obtained by milling, blending, and compacting the powders to obtain a fine grain-sized particle without aggregation. The grain size and particle nature were characterized using scanning electron microscope (SEM) and X-ray diffraction (XRD) techniques, respectively. The microstructure, density, hardness, and wear rate of the composites were studied. The pin-on-disc method is equipped to study the wear behaviour and coefficient of friction. The sintered density of the prepared Cu-15%Ni is 98.25 %, Cu-8%Sn is 98.20 %, Cu-15%Ni-8%Sn is 98.10 % and Cu-15%Ni-8%Sn-2%B4C is 95.26 % and lower specific wear rate has been recorded for Cu-15Ni-8Sn-2B4C 121×10-6 mm3/(Nm) and the addition of reinforcement B4C in Cu-Ni-Sn displays remarkable changes in wear rate and friction coefficient.

“…The T-6 heat treatment with an aging had a significant effect on wear resistance of composite [32]. Density,hardness and wear resistance of composites were improved with embeddments of SiC and B 4 C reinforcements [33,34]. From the literature, it is obvious that the wear process and wear mechanism are varying with respect to the experiments even for the same reinforcing particles.…”

In this study, boron carbide (B 4 C) and silicon carbide (SiC) nanoparticle reinforced aluminum matrix composites (AMC) were fabricated by stir cast method. The morphology of the SiC and B 4 C nanoparticles are analysed by scanning electron microscope (SEM). The Electron probe microanalysis and energy dispersive spectroscopic analysis were employed to confirm the dispersion of nano SiC and B 4 C particles in the aluminum matrix. The abrasion wear behavior of these composite materials was investigated under normal loads of 10 N, 20 N and 30 N. The effect of reinforcing materials on wear behaviour was investigated and the reinforced composites exhibits relatively high wear resistance compared to pure Al6063-T6 alloy. Wear resistance of the B 4 C reinforced AMCs was relatively higher than that of SiC reinforced AMCs at all the applied loads. SEM images of the worn surfaces revealed that micro fracture of the reinforcement composites was the predominant mechanism associated with 3 body abrasion wear. Moreover, SEM images revealed that the debris and detached particle formations are more in the nanoparticle reinforced AMCs. A strong interfacial interactions between Al matrix and SiC nanograin with strong Al-Si bonding is responsible for the high wear resistance. The wear mechanism is varied from abrasive to oxidative by increasing the normal load in all the samples. Moreover, the formation of a condensed spinel structure with the consistent matrix/particle interface bonding provides a substantial particle strengthening effect.

“…Copper when alloyed with Sn was found to show an intensive increase in properties like hardness which also improves the wear resistance of the material [4]. However, addition of reinforcements like Al 2 O 3 , SiC and B 4 C resulted in marginal surge in material density values as a result of increased sinterability with the addition of reinforcement [5]. An approach from M. Asnavandi et al [6], investigated on the effect of reinforcements like graphite and SiC which results in some alluring conclusions.…”

Copper have always been an important material and incorporation of elements into copper for property enhancement. Bronze is a relevant cuprous alloy which is important for many industrial and automotive applications like bearings and machineries. The present research is directed towards the fabrication and tribological analysis of regular bronze (Cu-6Sn) and metal matrix composites reinforced with varying particle sized SiC ceramic reinforcement (30, 35 and 40 µm). The developed specimens were subjected to wear analysis according to ASTM standards, to identify the tribological properties utilizing a pin on disk tribometer. It was noted that the wear rates of developed MMC's phenomenally decremented with an increase in size of SiC particle reinforcement. Also, the test parameters were influential in altering the wear rates to notable margins. The standard scanning electron microscopy techniques aided in identifying the influence of adhesive wear on the specimen surface.
