“…In the research work by Preetkanwal et al [154], a low corrosion value of 0.1146 mm/year was observed when machining a Ti alloy using a nano-HAp mixed dielectric in the EDM technique. Razak et al [180] studied how to develop a formula for controlling the corrosion rate of an Mg alloy applying zinc powders in the EDM method. In this research work, corrosion values ranging from 0.000183 mm/year to 0.001528 mm/year were obtained when 2 g/L zinc was added to the working fluid of the system.…”

Together, 316L steel, magnesium-alloy, Ni-Ti, titanium-alloy, and cobalt-alloy are commonly employed biomaterials for biomedical applications due to their excellent mechanical characteristics and resistance to corrosion, even though at times they can be incompatible with the body. This is attributed to their poor biofunction, whereby they tend to release contaminants from their attenuated surfaces. Coating of the surface is therefore required to mitigate the release of contaminants. The coating of biomaterials can be achieved through either physical or chemical deposition techniques. However, a newly developed manufacturing process, known as powder mixed-electro discharge machining (PM-EDM), is enabling these biomaterials to be concurrently machined and coated. Thermoelectrical processes allow the migration and removal of the materials from the machined surface caused by melting and chemical reactions during the machining. Hydroxyapatite powder (HAp), yielding Ca, P, and O, is widely used to form biocompatible coatings. The HAp added-EDM process has been reported to significantly improve the coating properties, corrosion, and wear resistance, and biofunctions of biomaterials. This article extensively explores the current development of bio-coatings and the wear and corrosion characteristics of biomaterials through the HAp mixed-EDM process, including the importance of these for biomaterial performance. This review presents a comparative analysis of machined surface properties using the existing deposition methods and the EDM technique employing HAp. The dominance of the process factors over the performance is discussed thoroughly. This study also discusses challenges and areas for future research.

“…The influence of this parameter significantly effecting to corrosion rate which the biodegradable preferred to material selection criteria. The zinc particles contained in the dielectric fluid were also shown to have an important effect on improvements in the magnesium alloy corrosion rate [40]. Kavimani et al, [41] revealed that powder concentration and pulse ON Time are the most influencing parameters for MRR and Ra.…”

Magnesium alloys have been widely used in biodegradable applications due to it tends to corrode inside the human body and combined with its initial mechanical property. Current research revealed that the structural stability of the implant is disturbed and lost rapidly due to the increased rate of degradation of magnesium inside the human body. Because of that, non-traditional machining method such as electrical discharge machining (EDM) die sinking process is implemented to create an intricate form with a high tolerance of magnesium alloy. The advantages of EDM are that it allows a versatile adaption of implant behaviour in machining complex 3D structures along with high corrosion resistant properties of electrochemical surface treatment. Various material types with different parameters are investigated to determine the influence of input process parameters on the energy saving, and machining characteristics included surface roughness, material removal rate, and tool wear rate. In addition to improving the machining performance especially in energy-saving, input on the machining parameter needs to be considered due to interaction with added conductive particles which would affect the size of discharge energy. The objective of this paper is to summarize the findings in research of EDM's energy-saving and machining characteristics on magnesium alloy and to explore challenging issues that need to be resolved for future references and recommendations.

“…Metallic biomaterials including stainless steel, Co-Cr, pure Ti and its alloys, pure Zr and its alloys were the most popularly used to fabricate prosthesis, especially for the repair or replacement of diseased bone [1,2]. The use of other metals such as Mg and Zn alloys were also reported, especially for the synthesis of biodegradable implants [3][4][5][6][7][8][9]. Metallic implants are most commonly used for the repair/replacement of hard tissues such as hip and joints, fixation devices, dental implants, cardiovascular stents, screws and bone plates [10,11].…”
