Corrosion resistance of pure titanium (Grade 2) and Ti−Pd alloy (Grade 7) was studied using the electrochemical techniques of potentiodynamic measurements and electrochemical impedance spectroscopy (EIS). Measurements were performed at the temperature of 36.6 °C in two solutions: PBS solution with pH of 7.4 simulating conditions of healthy human body, and PBS solution with pH of 5.2 and with th...

Electrochemical synthesis of poly ortho toludine (POTD) was achieved on Teflon coated cylindrical stainless steel electrodes with base diameter 2mm . Aniline in 2-propyl pentatonic acid solution was polymerized on the surface of stainless steel using cyclic voltametry technique. Adherent and red polymer films were obtained on the electrodes.. The corrosion inhibitive performance of POTD+2PPA , ...

Corrosion inhibitory effects of new synthesized compound namely 5,5'- ((1Z,1'Z)-(1,4-phenylenebis(methanylylidene))bis(azanylylidene))bis(1,3,4-thiadiazole-2-thiol) (PBB) on mild steel in 1.0 M HCl was investigated at different temperatures using open circuit potential (OCP), potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). Results showed that PBB inhibited m...

this paper focused on the characterization of electrochemical behavior of a martensitic stainless steel inthe acidic solutions. for this purpose, electrochemical parameters were derived from potentiodynamicpolarization, mott schottky analysis and electrochemical impedance spectroscopy (eis) techniques.the potentiodynamic polarization results showed that corrosion current density of aisi 420 sta...

Al–TiC nanocomposite materials have been prepared by a new in situ synthesizing technique. A mixture of aluminum, titanium, and graphite has been prepared using ball milling technique and then melted in a high frequency induction heat furnace (HFIHF) at different sintering temperatures, namely 900, 1100, and 1300 °C. The effect of sintering temperature on the corrosion of the Al–TiC composite i...

the corrosion inhibition characteristics of two synthesized schiff bases, namely n, n´-bis(2-hydroxy-6-nitrobenzaldehyde) benzidine  and n, n´-bis(salysylaldehyde) benzidine, on the mild steel corrosion in 2.0 m hydrochloric acid have been investigated by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy techniques. these studies were carried out at different ...

A new coumarin derivative, N,N'-((2E,2'E)-2,2'-(1,4-phenylenebis (methanylylidene))bis(hydrazinecarbonothioyl))bis(2-oxo-2H-chromene-3-carboxamide) PMBH, was synthesized and its chemical structure was elucidated and confirmed using spectroscopic techniques (Infrared spectroscopy IR, Proton nuclear magnetic resonance, 1H-NMR and carbon-13 nuclear magnetic resonance 13C-NMR). The corrosion inhibi...
