“…Chelladurai et al reported mild wear of metal matrix composites at lower load (e.g., up to 30 N), however, severe wear at higher load (e.g. 50 N) due to the higher level of deformation on the surface during dry sliding wear process [18]. Wear loss of composite materials reduces with the reinforcement material in the metal matrix because the reinforcing particles are effective to reduce the wear deformation [19][20][21].…”

In this study, copper matrix composites reinforced with graphite (5, 10, 15 wt%) were produced using powder metallurgy process. Milled powders were compacted under 637 MPa pressure to produce cylindrical specimens of approximate dimension of 10 mm diameter and 30 mm length. Cylindrical specimens were sintered under vacuum at 900, 950, 1000°C for 2 h holding time at highest temperature. Hardness and compression strength of composite samples were determined. The microstructures of specimens were investigated by optical microscope, scanning electron microscope and energydispersive spectroscopy. Homogeneous distribution of reinforcement phase in copper matrix composites was observed. Graphite reinforcement improved the compression strength of composites of around 108% with 5 wt%, around 34% with 10 wt% of reinforcement. However, significant decrease of compression strength was observed with 15 wt% of graphite reinforcement in the copper matrix. Reinforcement of graphite into copper matrix has improved the wear property of the composite materials.

In this study, a newly engineered stir-cast LM13 aluminium alloy-based hybrid composite (5 wt% of TiC and 10 wt% of ZrB 2) is used as workpiece and its machinability investigation is carried out using EDM (electric discharge machining) drilling route with copper electrode. During experimentation, the process variables, namely current (I), pulse on-time (T on) and pulse off-time (T off), are varied and the output performance characteristics, viz. material removal rate (MRR), electrode wear rate (EWR) and dimensional accuracy, i.e. overcut (OC), are measured. The series of experiments (20 runs) are formulated through the adoption of response surface methodology (RSM)-based full-factorial central composite design. To recognize the correlation between the process variables and performance characteristics, a mathematical model is developed for each response. Subsequently, adequacy of the proposed models is verified using analysis of variance (ANOVA). Moreover, ANOVA is employed to identify the significantly influencing process parameters over the performance characteristics. From the analysis of results, it is inferred that the current has the most dominant effect on MRR and EWR, whereas OC is highly influenced by T on. Composite desirability function approach of RSM is utilized to find the optimum set of process parameters in order to satisfy the desired multi-performance characteristics (such as maximizing MRR, minimizing EWR and OC) for obtaining effective holes on hybrid LM13-10ZrB 2-5TiC composite. Finally, optimized results are validated with the experimental results to determine the competence of adopted desirability approach.

“…LM13 aluminium alloy is selected in this work because of its high silicon content. Many researchers have attempted the reinforcement of SiC, Al 2 O 3 , C, B 4 C, Fe, WO, MgO, AlB 2 , quartz and rock dust in aluminium alloy and observed the improvement in hardness, tensile strength and wear resistance compared to matrix [4][5][6][7][8][9][10][11][12][13][14].…”

LM13 aluminium alloy (Al−Si12CulMg1) with titanium diboride (TiB2) and boron carbide (B4C) particulate hybrid composites have been prepared using stir casting process. Wt% of titanium diboride is varied from 0–10 and constant 5 wt% boron carbide particles have been used to reinforce LM13 aluminium alloy. Microstructure of the composites has been investigated and mechanical properties viz., hardness, the tensile strength of composites have been analyzed. Wear behavior of samples has been tested using a pin on disc apparatus under varying load (20 N–50 N) for a sliding distance of 2000 m. Fracture and wear on the surface of samples have been investigated. Microstructures of composites show uniform dispersion of particles in LM13 aluminium alloy. Hardness and tensile strength of composites increased with increasing wt % of reinforcements. Dry sliding wear test results reveal that weight loss of composites increased with increasing load and sliding distance. Fracture on the surface of composites reveals that the initiation of crack is at the interface of the matrix and reinforcement whereas dimples are observed for LM13 aluminium alloy. Worn surface of composites shows fine grooves and delamination is observed for the matrix.
