In this work, TiNi samples were prepared by Selective Laser Melting (SLM) technology, and the influence of microstructure, fluoride ion, pH value on corrosion behavior in a saline environment was investigated compared with alloy fabricated traditional forging technology. The results indicated that resistance SLM sample slightly superior to wrought due uniform dense oxide film formed surface. Ho...

There is limited research on metastable pitting corrosion in an acidic environment, and acid a major challenge for material corrosion. Therefore, this work investigated the of laser powder bed fusion (LPBF)-produced Ti–6Al–4V, Hank’s solution, at different pH values (pH = 3, 5, 7). This effect characteristics passive films, as well change behavior. Based results electrochemical impedance spectr...

most of the researches do not differentiate between intuitive critic and passive one – in the field of features, applications and methods. this critical school is called emotional or passive critics which emphasizes aesthetics. thus sensitivity is not the only appliance to wisdom but is a mean to inspire happiness or unhappiness feeling. consequently the passive (critical) school is the result ...

The relationship between chloride ion concentration and pH on de-passivation of steel rebar embedded in concrete was investigated by a two frequencies impedance measurement using probe electrodes. A saturated calcium hydroxide solution used for the electrolyte as simulated pore solution. pair electrodes, which simulates rebar, immersed prepared an arbitrary ions, performed. Air supplied to simu...
