Another group of optimal parameters for the ECM of 10%(mass fraction) SiC/Al matrix composites was obtained by Dharmalingam et al [291]. The optimal values for maximum MRR were machining voltage 7 V, electrolyte concentration 24 g/L, and frequency 50 Hz.…”

Among the various types of metal matrix composites, SiC particle-reinforced aluminum matrix composites (SiC p /Al) are finding increasing applications in many industrial fields such as aerospace, automotive, and electronics. However, SiC p /Al composites are considered as difficult-to-cut materials due to the hard ceramic reinforcement, which causes severe machinability degradation by increasing cutting tool wear, cutting force, etc. To improve the machinability of SiC p /Al composites, many techniques including conventional and nonconventional machining processes have been employed. The purpose of this study is to evaluate the machining performance of SiC p /Al composites using conventional machining, i.e., turning, milling, drilling, and grinding, and using nonconventional machining, namely electrical discharge machining (EDM), powder mixed EDM, wire EDM, electrochemical machining, and newly developed high-efficiency machining technologies, e.g., blasting erosion arc machining. This research not only presents an overview of the machining aspects of SiC p /Al composites using various processing technologies but also establishes optimization parameters as reference of industry applications.

“…Studies explore the design of different machining parameters to enhance material removal rates and improve surface roughness in ECM [16][17][18]. For example, Dharmalingam et al [19] obtained the optimal values for minimum overcut for the ECM of 10% SiCp/Al. Jet Electrochemical Machining (JECM), a type of ECM, extracts electrolyte through a nozzle, generating a high-velocity free jet stream [20][21][22].…”

Silicon carbide particle reinforced aluminum matrix composites (SiCp/Al), combine the properties of aluminum matrix materials and reinforced silicon carbide (SiC) particles, finding widespread application in aerospace, optics, and electronics. The increased hardness and electrochemical inertness of SiC particles present significant challenges in their processing. This research investigates the impact of photocatalytic processes on machining accuracy in electrochemical processing (ECM). The dissolution characteristics of SiCp/Al during ECM and photocatalytic-assisted electrochemical machining (PAECM) were analyzed with varying electrolyte compositions, using polarization curves and oxidation-reduction potential (ORP). Validation of improved machining accuracy in PAECM was achieved through no-feeding machining. PAECM, with its photocatalytic reactions, effectively blocked stray currents and stray corrosion, enhancing accuracy in profile creation. Comparative analysis revealed that PAECM exhibited smoother profiles and reduced Overcut Ratio (OCR) in hole and groove machining compared to ECM, particularly in groove machining. Adjusting machining gaps and reducing abrasive particle size in PAECM influenced groove depth and width, achieving optimal morphology with a 0.4 mm gap and a 2-3 nm abrasive particle size, resulting in a 370 μm depth.
