“…The different behaviour of corrosion resistance of investigated composite materials could have resulted from the changing of microstructure that showed distinctive phases formed based on the amount of %wt Mn and Zr. The role of the occurred phases here could be explained by the role of corrosion barrier where the homogeneously distributed phases impart to more resistance regions to corrosive attacks due to anodic and cathodic behaviour of materials was changed by these regions [20]. The addition of 0.5 %wt Mn to base changed the α phase as broader and therefore worse corrosion resistance was obtained than the base.…”

In this study, composite biomaterials were produced by powder metallurgy (P/M) method. Ti-6Al-4V master alloy and different proportions of Mn and Zn have been added to this alloy. Dry wear test and electrochemical corrosion test in Hank fluid (Body fluid) were applied to the produced composite P/M materials. The addition of Mn in the produced materials was effective in improving the wear behavior of the Ti-6Al-4V composite material. In addition, the addition of Zr provided excellent corrosion resistance in Hank's solution. The superior properties of Ti-6Al-4V composite material with its microalloy approach are quite challenging for biomedical applications. The best wear resistance was achieved by adding 2%Mn to Ti-6Al-4V by weight. In addition, it was observed that the phases formed as a result of the addition of 2% Zr act as a barrier during corrosion.

“…HCP (hexagonal package structure) reduces the easy forming of Mg alloys and weakens the competitiveness of sheet Mg products [2]. It is known that rare earth elements increase the formability of AZ31 Mg alloy [3]. On the other hand, the corrosion resistance of Mg alloys is poor and coating and alloying in order to improve corrosion resistance are quite popular [4][5].…”

In this study, the effect of Shot Peening (SP) and Micro Arc Oxidation (MAO) process on the corrosion resistance of 0.5% La with added AZ31 Mg alloy, hot rolled at different rolling speeds, was investigated. It was found that the surface of the rolled material at a rolling speed of 4.7m/min had higher surface smoothness values than the one rolled at 10m/min. It was observed that the corrosion rate changed in the first 40 of 168 hours. In the following hours, the corrosion rate showed different results according to the initial microstructure properties of the base materials. Initially, pore size was the dominant factor determining corrosion resistance, although, after coating, the corrosion rate was affected by the twins formed, based on rolling speed, which enhanced the corrosion rate between 48 and 168 hours.

The effect of shot peening (SP) and Micro Arc Oxidation (MAO) were utilized to characterize the performance of the corrosion resistance process at 0.5 % Nt with add AZ31 Mg alloy. Hot rolling at different rolling speeds has been investigated in this work. The surface of the rolling materials a rolling speed of 4.7 m/min and the rolling materials a rolling speed of 10 m/min were measured to create a clear definition of corrosion resistance physical properties. Experimental results show the surface of the rolling materials a rolling speed of 4.7 m/min had higher surface smoothness values than the one of the rolling at 10 m/min. It was observed that the corrosion rate changed in the first 24 of 168 hours. In the following hours, the corrosion rate showed different results according to the initial microstructure properties of the base materials. Initially, pore size was the dominant factor determining corrosion resistance, although, after coating the corrosion rate was affected by the twins formed, based on rolling speed, which enhanced the corrosion rate between 24 and 168 hours.
