| Summary: | This paper presents the investigation of compounds /
phases formed during the Electrical Discharge Machining
(EDM) of titanium alloy (Ti-6AI-4V) with Cu-TaC compact
electrode using urea dielectric fluid. It is proposed that the
materials involved in the machining are likely to react and
form new compounds on the EDMed surface. The outcomes of
the reactions were predicted. The EDMed surfaces were
subjected to energy dispersive X-ray spectroscopy (ED X) and
X-ray diffraction (XRD) analysis to determine the changes in
the surface composition. Results of EDX analysis indicate the
presence of additional elements (Cu, Ta, 0 and C) on the
surface of the parent alloy. XRD results also confirm the main
compounds formed on the surface to include metallic oxides,
carbides and nitrides (TaC, TiC, Ti1N, TiD) of tantalum and
titanium. It is concluded that the surface was reinforced during
the EDM with hardened ceramic layers which are capable of
enhancing its wear properties. |
