“…Fine graded W powders of size less than 45 μm with a purity level of 97.92% were used as another reinforcement. density is due to addition of 6% of low density FA and 3% W. The reason is in good agreement with Thanga Kasi Rajan et al [24] and Balamurugan et al [15] reported that the addition of FA in Cu matrix decreases the relative density of the composites. The increase in addition of reinforcement obviously increases the porosity of the fabricated samples in P/M process as FA is in large volume compared to W. The density increases when the percentage addition of W increases.…”

“…One factor which reduces the cost of fabrication is to reinforce the low cost material. Some of the low density reinforcement materials which are widely used in copper are MoS 2 , SiC, Al 2 O 3 , graphite, and Fly Ash (FA) [13][14][15][16][17][18].…”

“…Several researchers were started to utilize FA. Balamurugan et al [15] discussed the various process and influencing parameters in the fabrication and tribological behavior of Cu-FA composite material. The major problem encountered in addition to FA in the copper matrix is its density (volume fraction).…”

This research paper describes the enhancement of mechanical, wear and corrosion behaviour of the Copper (Cu) matrix composite by reinforcing Fly ash (FA) and Tungsten (W). The main objective of this study was to reduce the weight and cost of the hybrid composites. The weight percentage of low density material (FA) was kept constant at 6% and samples were prepared by the addition of W in weight percentages of 3, 6 and 9 in the Cu matrix. The characterization of the hybrid composites was studied using a Scanning Electron Microscope (SEM) and Energy-dispersive spectroscopy (EDS). The micrographs revealed the uniform distribution of W and FA in the Cu matrix. From the mechanical characterization, it was identified that there is an increase in microhardness and compressive strength with the addition of W particles. It can be understood that the W particles occupy substitutional type reinforcement and FA particles occupy interstitial type reinforcement in the Cu matrix. The Wear behavior and its mechanism were studied using worn surface SEM micrographs. It was observed that the lowest specific wear rate was recorded for the hybrid composition of Cu-6FA-6W. Electrochemical polarization test and Electrochemical Impedance Spectroscopy (EIS) study revealed that Cu-6FA-9W shows higher corrosion resistance in both 1 N HCl (256.593×10 −4 Ω cm 2 ) and seawater media (219.855×10 −4 Ω cm 2 ) than pure Cu.
