“…The use of Ti-base alloys in various fields comes from its super biocompatibility, excellent mechanical properties, and great corrosion resistance in many aggressive environments [10][11][12][13][14]. The use of titanium alloys in offshore structures and marine applications results from it low density, superior strength, and extremely high resistance to corrosion [2,3,[15][16][17][18][19][20]. Another important usage of titanium alloys is as an outstanding and strong material in the field of biomedical implantations [8][9][10][11][12][13][14][15]21].…”

The beneficial effects of V addition on the corrosion of a newly manufactured Ti6AlxV (x = 2 wt %, 4 wt %, 6 wt %, and 8 wt %) alloys after various exposure periods in 3.5% NaCl solutions were reported. The Ti6AlxV were produced from their raw powders using mechanical alloying. Several electrochemical techniques such as electrochemical impedance spectroscopy, cyclic potentiodynamic polarization, and potentiodynamic current versus time at 300 mV experiments were conducted. The surface morphology and the elemental analysis were performed using scanning electron microscopy and energy dispersive X-ray analyses. All results were consistent with each other revealing that the increase of V content increases the resistance of the alloys against corrosion. The increase of corrosion resistance was achieved by the role of V in decreasing the rate of corrosion as a result of the formation of oxide films on the surface of the alloys. This effect was found to increase with prolonging the immersion time of the Ti6AlxV alloys in the test medium from 1 h to 24 h and further to 48 h. particularly in implantation systems [24][25][26]. Other titanium alloys like Ti6Al7Nb and Ti13Cu4.5Ni, in addition to the Ti6Al4V alloy, have been selected as the only choice for the use in orthopedic implants [27]. It has also been reported [28][29][30][31][32][33][34] that resistance versus corrosion in-vitro to form a stable oxide film in harsh media is the main reason for these alloys to be popular and applicable in the field of biomedical applications.In this work, we aimed to produce a series of Ti-base alloys, namely Ti6Al2V, Ti6Al4V, Ti6Al6V, and Ti6Al8V alloys, from its pure powders, and reported their corrosion after immersion in 3.5% NaCl solution for different periods of time, namely 1 h, 24 h, and 48 h. The effect of increasing V content within the fabricated alloys on their corrosion in the test solution was reported using various electrochemical techniques like polarization, electrochemical impedance spectroscopy, and potentiostatic current-time at 300 mV (Ag/AgCl). Other surface analysis methods, including scanning electron microscopy (SEM) images and energy dispersive X-ray (EDX) spectra, were performed to ensure the compositions, the surface morphology, and expected corrosion products that might be formed after corrosion due to the reaction between the surfaces of the alloys and the chloride test solution.

The current research aims at the manufacturing of Ti-6%Al alloy and Ti-6%Al-4%V alloy using the mechanical alloying method and studying their corrosion behavior after various periods of immersions in 3.5% NaCl solutions. The fabricated alloys were also evaluated using spectroscopic techniques such as X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray spectroscopy analyses. The corrosion behavior was studied using potentiodynamic polarization, electrochemical impedance spectroscopy, and chronoamperometric current-time electrochemical methods. It is confirmed that the presence of 4% V greatly decreases the uniform corrosion of the Ti-6%Al alloy as a result of the role of V in decreasing the cathodic, anodic, and corrosion current, and the rate of corrosion along with increasing the corrosion resistance. Increasing the time of immersion to 24 h and further to 48 h highly decreased the corrosion of the alloys. The presence of 4% V and extending the time of exposure thus increase the resistance against corrosion via decreasing the corrosion of Ti-6%Al alloy in the chloride test solution. ; writing-original draft preparation, E.-S.M.S. and H.S.A.; writing-review and editing, E.-S.M.S.; supervision, E.-S.M.S.; project administration, E.-S.M.S.; funding acquisition, E.-S.M.S.

The high temperature corrosion characteristic of Super304H, TP347H, and HR3C steel in an ultra‐supercritical coal‐fired boiler with service time of 17,973 h was investigated. The samples were analyzed by XRD, SEM, and EDS. The results showed that corrosion scales were composed and could be divided into three layers, including outer layer with composite reaction of alkalis and sulfate, middle layer with oxidation, and penetrated inner layer with oxidation and sulfidation. In addition, spalling of corrosion scales in the Super304H and TP347H samples was observed with the reasons of low Cr content and thermal expansion difference between different corrosion layers.
