“…Moreover, studied alloys exhibited good corrosion resistance but smaller wettability in comparison to Ti6Al4V alloys [ 45 ]. Corrosion resistance measurements of three high entropy compositions TiTaHfNb, TiTaHfNbZr and TiTaHfMoZr, designed as medical implants, were described by Gurel et al [ 46 ]. Corrosion resistance measurements were performed for long-term studies by immersion in simulated body fluid (SBF) and artificial saliva (AS) mixtures.…”

The presented work was focused on investigating the influence of the (hafnium and zirconium)/molybdenum ratio on the microstructure and properties of Ti20Ta20Nb20(ZrHf)20−xMox (where: x = 0, 5, 10, 15, 20 at.%) high entropy alloys in an as-cast state. The designed chemical composition was chosen due to possible future biomedical applications. Materials were obtained from elemental powders by vacuum arc melting technique. Phase analysis revealed the presence of dual body-centered cubic phases. X-ray diffraction showed the decrease of lattice parameters of both phases with increasing molybdenum concentration up to 10% of molybdenum and further increase of lattice parameters. The presence of two-phase matrix microstructure and hafnium and zirconium precipitates was proved by scanning and transmission electron microscopy observation. Mechanical property measurements revealed decreased micro- and nanohardness and reduced Young’s modulus up to 10% of Mo content, and further increased up to 20% of molybdenum addition. Additionally, corrosion resistance measurements in Ringers’ solution confirmed the high biomedical ability of studied alloys due to the presence of stable oxide layers.

“…For the TiTaHfMoZr sample, a significant amount of ion release upon immersion in both media was observed due to an inhomogeneous microstructure leading to the formation of dendritic structures. However, passive layers on all sample surfaces ensure corrosion resistance in long-term applications [ 46 ].…”

In the present study, high-entropy Ti x Nb 0.5 MnMo 0.5 Zr 0.3 (x = 0.5, 0.75, 1) thin films with excellent corrosion behavior were deposited on AISI 316L using direct current magnetron sputtering. The deposited films were structurally characterized using X-ray diffraction and field-emission scanning electron microscopy. The results confirmed the formation of an face-centered cubic structure with a uniform distribution of constituent elements. It was

“…So far, extensive research has been conducted to gain an in‐depth understanding of the influence of microstructural characteristics on corrosion behavior in Ti alloys, processed via different routes. [ 14,16–18 ] As reported previously, LPBF has been efficient in fabricating Ti6Al4V with improved mechanical properties when compared with the ones fabricated using conventional techniques. [ 19–22 ] Also, depending on the laser scanning strategy, LPBF has been found to tune the corrosion resistance behavior of Ti6Al4V, when compared with their conventional counterparts.…”

Herein, the spatial variation in the electrochemical behavior of laser powder bed fusion (LPBF)‐fabricated Ti6Al4V alloy is investigated. The electrochemical behavior of LPBF‐printed Ti6Al4V is measured using potentiodynamic polarization and electrochemical impedance spectroscopy at different regions along the build direction. The varying kinetics in electrochemical response is characterized using scanning electron microscopy and X‐ray diffraction, which confirm the variation in (0002) texture in the build plane of LPBF‐printed Ti6Al4V. The thermokinetics of LPBF‐printed Ti6Al4V is understood by developing a multiphysics computational model using the finite‐element method, which is conducive to apprehending the spatial variation in electrochemical response kinetics.
