“…The results of their study exhibited the improved specific wear rate and coefficient of friction due to the formation of oxides and carbide layers on the machined surface. Besides, Devgan and Sidhu [ 15 ] executed electro discharge treatment for investigating the surface wettability and corrosion resistance responses of β-titanium alloy. Simao et al [ 16 ] scrutinized the impact of EDM process parameters on various responses such as material removal rate (MRR), tool wear rate (TWR) and surface hardness of AISI H13 tool steel.…”

The present article focused on the surface characterization of electric discharge machined duplex stainless steel (DSS-2205) alloy with three variants of electrode material (Graphite, Copper-Tungsten and Tungsten electrodes). Experimentation was executed as per Taguchi L18 orthogonal array to inspect the influence of electric discharge machining (EDM) parameters on the material removal rate and surface roughness. The results revealed that the discharge current (contribution: 45.10%), dielectric medium (contribution: 18.24%) majorly affects the material removal rate, whereas electrode material (contribution: 38.72%), pulse-on-time (contribution: 26.11%) were the significant parameters affecting the surface roughness. The machined surface at high spark energy in EDM oil portrayed porosity, oxides formation, and intermetallic compounds. Moreover, a pin-on-disc wear analysis was executed and the machined surface exhibits 70% superior wear resistance compared to the un-machined sample. The surface thus produced also exhibited improved surface wettability responses. The outcomes depict that EDMed DSS alloy can be considered in the different biomedical and industrial applications.

“…Here, the atomic weight of Cu is 64 g/mol and the valency is +2. The operative area of each sample is 3 cm 2 , and ρ the density of copper substrate is 8.91 g/cm 3 , and the corrosion rate constant K = 3272 mm/(A cm year) [ 42 , 43 ]. From the potentiodynamic polarization curve, the average corrosion current ( I corr ) of bare substrates and graphene-coated samples is 1.58 × 10 −3 mA and 6.51 × 10 −5 mA, respectively.…”

Due to the excellent chemical inertness, graphene can be used as an anti-corrosive coating to protect metal surfaces. Here, we report the growth of graphene by using a chemical vapour deposition (CVD) process with ethanol as a carbon source. Surface and structural characterisations of CVD grown films suggest the formation of double-layer graphene. Electrochemical impedance spectroscopy has been used to study the anticorrosion behaviour of the CVD grown graphene layer. The observed corrosion rate of 8.08 × 10−14 m/s for graphene-coated copper is 24 times lower than the value for pure copper which shows the potential of graphene as the anticorrosive layer. Furthermore, we observed no significant changes in anticorrosive behaviour of the graphene coated copper samples stored in ambient environment for more than one year.

Surface modifications play a vital role in the performance of bio-implants. Powder mixed electric discharge machining (PM-EDM), a recently developed advanced machining method, can machine and coat the surface of conductive materials at the same time. Hydroxyapatite is a bio-ceramic with a bone-like composition and excellent biocompatibility. Several coating techniques are used to deposit a bio-ceramic layer on the implant surface; however, hydroxyapatite powder mixed-EDM (HAp-EDM) is an electro-thermal process that can be used for surface coating as well as machining of metallic biomaterials. In this review article, surface characteristics such as surface morphology/topography, micro-hardness, phase analysis, recast layer, elemental composition, corrosion/wear resistance, and biocompatibility of the coated surface of an implant after HAp-EDM have been meticulously reviewed. This review also looks at future research opportunities for the HAp-EDM process to meet the high standards required for biomedical materials and their applications in bio-implant manufacturing.
