An Academic staff at the University of Kufa publishes a scientific research in the Journal of Bio- and Tribo-Corrosion

A. Prof. Dr. Ali Sabaa Hamoud, an academic staff at the Faculty of Engineering in the University of Kufa, together with the researchers Safaa Hussain Hadi from University of Kufa and Dr Thaer Latief from the ministry of Science and Technology, have published a scientific research paper entitled:
” Corrosion Behavior Evaluation in Simulated Body Fluid of a Modified Ti–6Al–4V Alloy by DC Glow Plasma Nitriding”

In the international scientific journal (Journal of Bio- and Tribo-corrosion), which is a part of the Springer publishing company within (SJR – Q2).
Hamoud explained that DC glow discharge plasma nitriding is the process of surface hardening through the spread of nitrogen atoms to the metal surface under special conditions of the plasma nitriding. He added that titanium alloys are the most common alloys which uses in the medical applications due to its lightweight, corrosion resistant and good fatigue properties. However, it lacks to resist the corrosion under the aggressive environments. He pointed that the plasma nitriding process was used for a titanium alloy bar at different nitriding times (5, 10 and 15 hours) and the effect of plasma nitriding on the chemical compassion of Ti-6Al-4V alloy has been examined. The appearance of phases were studied by optical microscopy (OM), Scanning electron microscopy and field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Tafel potential polarization and cyclic polarization.
The results indicate that the formation of layers and phases Ti2N and Ti2N3-x on a surface of the alloy were achieved, which would improve the surface characteristics of chemical corrosion in simulated body fluid.
