چکیده

Nowadays titanium alloys are extensively used for aerospace and biomedical applications. However, despite good mechanical properties and excellent corrosion resistance they possess poor wear resistance and a tendency to galling and seizure. In this study the tribological properties of experimental Ti-Si-Zr based alloys were studied using a standard ball-on-disc wear testing system. The wear and friction tests were conducted in bovine serum solution under room temperature using silicon nitride balls as counter-bodies. Measurements of friction coefficients and volumetric wear rates were made and microscopic investigations of the wear tracks were performed along with examination of structure and properties using light microscopy, XRD, SEM and hardness testing.

An investigation on metallurgical and mechanical properties of vacuum brazed Ti-6Al-4V to 316L stainless steel using Zr-based filler metal

Both Ti-6Al-4V and 316L stainless steels are widely used as engineering alloys. Fusion welding of these two alloys is not easily possible due to their incomplete solubility in each other. Brazing is one of the best choices for joining dissimilar alloys. In this study, wettability experiments were done at 940 and 970 ºC for 5, 15 and 30 min. Also, joining of these two alloys was carried out at 9...

Microstructural evolution of body-centered cubic structure related Ti–Zr–Ni phases in non-stoichiometric Zr-based Zr–Ti–Mn–V–Ni hydride electrode alloys

Non-stoichiometric Zr-based alloys were prepared, and the corresponding electrochemical properties were characterized as hydride electrode alloys. The microstructure and chemical composition of non-stoichiometric Zr–Ti–Mn–V–Ni hydride electrode alloys were systematically investigated by x-ray Rietveld refinement, transmission electron microscopy (TEM), and energy dispersive spectroscopy under T...
