“…The microstructure of the Ti alloys can be modified by heat treatment, thermomechanical processing, and electroshocking treatment, which improve the mechanical properties through microstructural refinement that change the grain structure and size to ultrafine and even to nanodimensions [26][27][28]. Thus, considering the advantages of altering the microstructure, the need for researchers to develop a simple and efficient microstructural transformation method to improve the properties of Ti alloys is emphasized [26].…”

The high specific strength, good corrosion resistance, and great biocompatibility make titanium and its alloys the ideal materials for biomedical metallic implants. Ti-6Al-4V alloy is the most employed in practical biomedical applications because of the excellent combination of strength, fracture toughness, and corrosion resistance. However, recent studies have demonstrated some limits in biocompatibility due to the presence of toxic Al and V. Consequently, scientific literature has reported novel biomedical β-Ti alloys containing biocompatible β-stabilizers (such as Mo, Ta, and Zr) studying the possibility to obtain similar performances to the Ti-6Al-4V alloys. The aim of this review is to highlight the corrosion resistance of the passive layers on biomedical Ti-6Al-4V and β-type Ti alloys in the human body environment by reviewing relevant literature research contributions. The discussion is focused on all those factors that influence the performance of the passive layer at the surface of the alloy subjected to electrochemical corrosion, among which the alloy composition, the method selected to grow the oxide coating, and the physicochemical conditions of the body fluid are the most significant.

Electroshocking treatment (EST) was a method to optimize the microstructure of titanium alloy. Under EST, the dense basket-weave structure in Ti-6.5Al-3.5Mo-1.5Zr-0.3Si (TC11) manufactured by laser melting deposition became sparse, and colony tissue nucleation grows near grain boundaries. The phase transformation induced by EST results in changes in the intensity and orientation of α and β textures in TC11, but α/β still obeyed the Burger orientation relationship, and the β phase content increased. At the same time, EST also promoted the dislocation movement near the grain boundary, and a mass of dislocation accumulation at the grain boundary increased the KAM value at the grain boundary.

“…It is somehow like the electropulsing treatment (EPT), which also applies a pulse current on the specimen to change the microstructure and strengthen the properties. However, unlike EPT, EST is a novel method that has low energy consumption and high efficiency [4,5] , and can rapidly optimize the microstructure alloys in a short time, induce desired phase transition and reduce texture, thus improving their properties. Guo [6] applied EST on DED Ti-55531 specimens, after which the hardness of the specimen decreased slightly while the ductility increased significantly; Levitin et al [7] found that the strong electric pulse would make the lattice defects undergo directional healing, which not only improves the fatigue resistance but also reduces the surface residual stress alloys.…”

The electro-shocking treatment (EST) was a rising method for the strengthening of titanium alloys. This work conducted EST on Ti-8Al-1Mo-1V titanium alloy specimens with the purpose to shed insights on the influence of EST on the properties of the alloy. The results indicated that the number of the pulse current increased, the properties of the Ti-8Al-1Mo-1V titanium alloy were notably improved, and the fracture mode varied from ductile fracture to a mixed fracture mode of brittle and ductile.
