Originality/value In this research, Ti6Al4V RF sputtering as a coating for SS316L, study the bio corrosion behaviors in Simulated body fluid Ringer solution and investigation the corrosion by using EIS analysis.

Investigations on the formability, tensile properties, TEM, 3D-surface roughness and corrosion behaviour on Ti–6Al–4V alloy sheets during single point and multi point incremental forming process

“…In previous studies, the researchers had focused (Siyah et al , 2019) on the electrochemical impedance spectroscopy (EIS) and potentio-dynamic polarization (PDP) effects of Ti–6Al–4V alloy coated on corrosion behaviours of SS316L during the ringer solution. The corrosion rate for Al 6061 alloy is higher when compared with composite materials in corrosion media due to its galvanic effects.…”

“…It possesses super elasticity and shape memory effect. Due to its excellent biocompatibility, which is comparable with that of Ti, along with shape memory and super elasticity properties, Ni-Ti alloy draws more attention in biomedical applications than other metallic constituents [1]. The Ni-Ti SMAs are among the most popular SMAs for biomedical applications, including stents or medical and dental wires, due to the relative ease of formability and improved fracture and fatigue resistance compared with other commercial shape memory alloys [2].…”

Investigations on strain distribution, stress-based fracture limit and corrosion behaviour of titanium Grade 2 sheets during single point incremental forming

“…Khun et al studied the wear and corrosion resistances of cold sprayed titanium coatings, which enhanced the wear resistance of titanium coatings performed higher than Ti-6Al-4V substrates due to the work hardening of the cold sprayed titanium coatings (Khun et al, 2016). Siyah et al (2019) have done an investigation on the potentiodynamic polarization (PDP) and electro chemical impedance spectroscopy (EIS) effects of Ti-6Al-4V alloy coated on corrosion behaviour of SS316L during the ringer solution.…”
