“…17,18 Coating on reinforcements improves the wetting behavior and interface bonding between matrix and reinforcement. Mandal et al 19 and Ganesh et al 20 reported that reinforcement of copper, nickel and zinc coating on steel¯bers/wires in aluminium matrix showed improvement in hardness, tensile strength and wear resistance. It was also observed that coating on reinforcement prevented the formation of intermetallic compounds and the composite material offered better mechanical properties and wear resistance compared to monolithic material.…”

Zinc-coated steel wires (1–5 numbers) reinforced in LM6 matrix composites have been prepared by squeeze casting process. Microstructure, hardness, tensile strength, ductility and dry sliding wear behavior of composites have been investigated by varying sliding distance and load. Fracture surface of tensile specimens and worn out surface of wear samples have been examined using field emission scanning electron microscope (FESEM). The results reveal that hardness of composites increased with increasing distance from matrix to steel wires. Maximum hardness values of 751 VHN and 611 VHN are observed in steel wire and at the interface of steel wire — aluminium, respectively. Tensile strength of composites increased upto 24% by reinforcing three steel wires in matrix. During the wear test, weight loss, wear rate and coefficient of friction decreased with increasing number of wires embedded in matrix and increased with increasing sliding distance and load. LM6 aluminium alloy reinforced with five numbers of steel wires decreased the weight loss upto 17% as compared to matrix under 40[Formula: see text]N load and a sliding distance of 2000[Formula: see text]m. Fracture surface of tensile specimen shows dimple formation in matrix and broken wires are observed in composites. Worn surface of composites shows fine grooves, whereas delamination is observed in matrix. In general, reinforcement of zinc-coated steel wires in LM6 aluminium alloy exhibited better mechanical properties and wear resistance compared to matrix.

“…The interface bonding between matrix and reinforcement can be improved by proper coating on reinforcements [18][19][20][21][22][23][24]. Copper coating on reinforcement offered better interface bonding between matrix and reinforcement [25]. Copper coated steel fiber reinforced composites exhibited better hardness over aluminum, aluminum reinforced with nickel and uncoated steel fibers.…”

Copper coated steel fibers reinforced LM13 aluminum alloy composites have been prepared using stir casting process. Experiments have been designed using response surface methodology (RSM) by varying wt % of reinforcement (0–10), stirrer speed (350 min−1–800 min−1) and pouring temperature (700 °C–800 °C). Microstructure and hardness of composites have been investigated. Analysis of variance, significance test and confirmation tests have been performed and regressions model has been developed to predict the hardness of composites. Response surface plots reveal that hardness of composites increases with increasing wt % of reinforcement and stirrer speed. The optimum stir cast process parameters for obtaining higher hardness are found to be the wt % of reinforcement of 8.2, pouring temperature of 748 °C and stirrer speed of 708 min−1.

“…Coating of reinforcement is a relatively effective way to reduce the extensive interfacial reaction and improve the interface bonding between the whisker and matrix [13][14][15][16][17][18]. To control the interfacial reaction, many researchers prepared different coatings (such as Cu, Cr 2 O 3 and Al 2 O 3 ) on the surfaces of ABOw by various methods.…”
