“…This phenomenon has been reported in the literature; the growth rate of MAO coating would decline as the duration increases. [43] Similar to the MAO samples, a relatively large change in the thickness of UMAO samples is observed from 5 min (13.5 AE 0.3 μm) to 10 min (16.8 AE 0.6 μm). However, when the duration prolongs to 15 min, the thickness of the UMAO sample surges to 25.4 AE 0.8 μm.…”

“…[34,41,42] However, rare literature has investigated the microarc oxidation of Ti-6Al-4V alloy with ultrasonic assistance for potential biomedical applications. [43] The effects of ultrasonic assistance on the detailed microstructural features of the produced oxide coatings on Ti-6Al-4V alloy are still not understood. Furthermore, considering the better performances of microarc oxidation coatings on Al alloys and Mg alloys produced with ultrasonic assistance and broad applications of Ti alloys in biomedical applications, it is highly significant to further investigate the performance of microarc oxidation coatings on Ti-6Al-4V using ultrasonic assistance.…”

Although microarc oxidation is frequently used in producing wear‐ and corrosion‐resistant coatings on Ti and Ti alloys for biomedical applications, the formation of nonuniform microstructure of the coatings is still unavoidable. To overcome this drawback, this work adopts ultrasonic assistance in the microarc oxidation of Ti–6Al–4V and systematically investigates the influences of ultrasonic treatment with different durations on the coating microstructures and resultant properties. The positive effects of ultrasonic, such as cavitation effect, sound flow effect, and mechanical effect, accelerate the cooling rate of electrolyte and promote the homogeneity of the solute on the sample surface. Therefore, the ultrasonic‐assisted coatings exhibit uniform microstructures with fewer cracks and therefore improve performances. For instance, compared with the counterpart without ultrasonic assistance, the ultrasonic‐assisted coating with 15 min duration demonstrates 25.1% lower mass loss in the tribology test and half corrosion density in Hank's solution. Such results indicate that ultrasonic assistance in microarc oxidation of Ti–6Al–4V can homogenize the microstructures of coatings and enhance their corrosion resistance and wear resistance in human body.

“…Titanium alloys have been used in various application areas including, but not limited to, aerospace, automobile, biomedicine, process industry including oil and gas.titanium alloys are the class of titanium alloys which have been widely used in the aerospace industry in larger quantities than other types because of their unique set of properties. Ductile fracture is an important consideration in their use and production [1][2][3]. It was established by the experiments carried out on Ti-10V-2Fe-3Al alloy which is an -titanium alloy, that void nucleation, growth and coalescence is the failure mechanism.…”

Crystal plasticity based finite element method (CPFEM) studies have been successfully used to model different material behaviour and phenomenon, including but not limited to; fatigue, creep and texture evolution. This capability can be extended to include the ductile damage and failure in the model. Ductile failure in metals is governed by void nucleation, growth, and coalescence. High strength titanium alloys can be formed from sheets and components and are prone to ductile failure. α-β Titanium alloys are in widespread use, ranging from aerospace, automotive, energy to oil and gas. They have multiple phases present in the microstructure but α and β phases are dominant and are present in various morphologies. This study focuses on the 3D representative volume element (RVE) simulations of spherical void of known initial porosity at the interface of α and β phase single crystals. The effect of initial porosity, applied triaxiality and orientation of RVE with respect to the loading direction is investigated. Slip based crystal plasticity formulation implemented as a user subroutine in commercially available software was used to simulate the void growth and the results of the same are presented. Lastly, a generalised correlation among loading type, loading direction, crystal orientation, phase interface orientation, and void growth is presented.

Bioactive Performances of Surface Modification of Ti–6Al–4V Jointly Using Ultrasonic‐Assisted Microarc Oxidation and Hydrothermal Treatment

With the aim of further enhancing the bioactive performance of Ti–6Al–4V, ultrasonic‐assisted microarc oxidation (MAO) and hydrothermal (HT) treatments are combined to produce denser, more uniform hydroxyapatite (HA) crystals on the MAO coating herein. More Ca elements can be deposited on the coating and more TiO2 can be generated to form a thicker coating via ultrasonic assistance. Meanwhile, the MAO coating with ultrasonic assistance avoids the appearance of heterogeneous areas and homogenizes the distribution of elements. Those positive effects of ultrasonic‐assisted MAO coating provide favorable conditions for the subsequent HT treatment to form dense and uniform HA crystals. In vitro experiment shows that the ultrasonic‐assisted MAO coating has a higher number of MG63 cells compared with other samples. Moreover, the formation of HA crystals improves the biological activity of all samples. In the ultrasonic‐assisted sample after HT treatment, denser and more uniform HA crystals on the coating surface result in the higher alkaline phosphatase activity of the sample.
