Abstract

The composite material manufacturing via in situ route is a popular method for developing the greater mechanical properties by reinforcing smaller volume of the ceramic phases. Electrochemical machining is widely employed for drilling smaller hole, machining the micro-slots and intricate shape on any material without considering its hardness. The present paper describes the electrochemical drilling of the composites reinforced with TiB2 ceramics under various reinforcement and volume contents of TiB2. Analysis of the experimental results indicates that the electrical parameters and electrolyte concentration offer significant effect on rate of material removal, delamination and radial overcut of drilled hole. The composite has minimum rate of material removal and maximum delamination and radial overcut than unreinforced alloy under ideal machining condition. Further, the effect of electrical parameters, electrolyte concentration and volume content of TiB2 on hole qualities are investigated via scanning electron microscopy and reported.
