“…Ti6Al4V is among the most widely used types of titanium alloys in aerospace, automotive, and biomedical applications because of its high mechanical properties, excellent corrosion resistance, low rate of ion release and excellent biocompatibility [1,2]. Titanium possesses a high sensitivity and reactivity towards oxygen, nitrogen, hydrogen, and carbon when it is heated above 650 ºC or within the liquid state [3].…”

A hybrid powder of Ti6Al4V, which consists of 50 wt% plasma atomised (PA) spherical and 50 wt% hydride-dehydride (HDH) irregular-shaped powder with a flowability of 36.5 s, is projected as the raw materials in this research. In addition, Ti6Al4V (Gr.23) plasma atomised 100 wt% spherical powder was used as the reference powder with a flowability of 28 s to facilitate the tensile property discussion. It was found that the powder flowability is the crucial parameter governing the tensile properties of fabricated specimens. It was shown that the decrease in powder flowability (36.5 s) resulted in increases in susceptibility to the formation of a lack of fusion defects with dropped tensile properties. The microstructure of the fabricated Ti6Al4V alloy features the formation of prior β grain boundaries and an alpha prime (α′) martensite. Furthermore, no intermetallic aluminide phase (Ti 3 Al) precipitations in grain boundaries were detected through energy-dispersive X-ray spectroscopy analysis.

“…Although Mg alloys exhibit numerous advantages over permanent implants, however, they display uncontrolled corrosion and degradation rate in the body fluid solution. Recently, clinical trials with Mg alloy implants have been explored as bone implants (Cha et al, 2013) and cardiovascular stents (Mani et al, 2007;Moravej and Mantovani, 2011;Chen and Thouas, 2015;Pandey et al, 2020).…”

Magnesium (Mg) based biodegradable materials are a new generation orthopedic implant materials that are intended to possess same mechanical properties as that of bone. Mg alloys are considered as promising substitutes to permanent implants due to their biodegradability in the physiological environment. However, rapid corrosion rate is one of the major constraints of using Mg alloys in clinical applications in spite of their excellent biocompatibility. Approaches to overcome the limitations include the selection of adequate alloying elements, proper surface treatment, surface modification with coating to control the degradation rate. This review focuses on current advances on surface engineering of Mg based biomaterials for biomedical applications. The review begins with a description of corrosion mechanism of Mg alloy, the requirement for appropriate surface functionalization/coatings, their structure-property-performance relationship, and suitability for biomedical applications. The control of physico-chemical properties such as wettability, surface morphology, surface chemistry, and surface functional groups of the coating tailored by various approaches forms the pivotal part of the review. Chemical surface treatment offers initial protection from corrosion and inorganic coating like hydroxyapatite (HA) improves the biocompatibility of the substrate. Considering the demand of ideal implant materials, multilayer hybrid coatings on Mg alloy in combination with chemical pretreatment or inorganic HA coating, and protein-based polymer coating could be a promising technique to improve corrosion resistance and promote biocompatibility of Mg-based alloys.
