Corrosion Behavior of TiNiPd RuCr Alloys in Hydrochloric Acid Barrier for Hydrogen A Study on the Anodic Behavior of Titanium and Some Ti Alloys. RAW MATERIALS MELTING. Estimating Domestic Titanium Requirements for the 90s Leaching of limenite with Sulfuric AcidThiourea Solutions. HID and. Phosphoric acid (PA) is an important industrial chemical used as an intermediate in the fertilizer industry, for metal surface treatment in the metallurgical industry and as an additive in the food industry. The PA industry is spread out worldwide in Europe, Asia and America, including countries that operate phosphate rock (PR) mines and produce PA, phosphatic fertilizers and phosphate-based.
The anodic behavior of the alloys in a wide potential range is studied using the potentiodynamic method and the method of stepwise raising anodic potential with an exposure of electrode at each potential for a certain time. The dependences of pitting potential on the concentration of solution are determined for two intermetallic compounds.

These confirmed the same trend for SRET. It means that SRET measurements are sensitive to study the electrochemical activity and corrosion behavior of Pb–Ag alloys specimens in the zinc sulfuric acid solution. Conclusions. The following conclusions may be drawn from the results of this paper work: : Wei Zhang, Wei Zhang, Georges Houlachi, Edward Ghali.

The polarization behavior of Pb-Ag (up to 1 wt% Ag) alloy anodes was determined in sulfuric acid solutions (H_2SO_4,g/l) in the presence of Cl^- or F^. The results are summarized as follows: 1) Cl^- and F^- significantly affect the variation of electrode potential with time over the first few hours of anodic : 梅津 良昭, 野坂 肇 and 戸沢 一光.

Mechanism of the processes of the processes during anodic oxidation of a lead electrode in sulfuric acid : Wei Zhang, Wei Zhang, Sanae Haskouri, Georges Houlachi, Edward Ghali. The cathodic and anodic potentiostatic polarization curves of titanium and its alloys in sulfuric and hydrochloric acid solutions were investigated.
It is shown that an increase in acid concentration causes an increase in the passivation current and a shift of the. XRD patterns of anodic layers on Pb (a), Pb-Ag (b), and Pb-CeO 2 ( wt%) (c) anodes after 72 h of galvanostatic polarization test in g/L sulfuric acid solution.
The oxide layer of the Pb-Ag anode mainly consisted of α-PbO 2 phase, while β-PbO 2 was also be observed. α-PbO 2 and β-PbO 2 in this sample showed preferential growth. The anodic behaviour of lead has been studied at Pb/PbSO4 and PbSO4/PbO2 potentials in sulphuric acid solutions in presence of copper and cobalt ions by galvanostatic and potentiokinetic methods.

The aim of this study is to find out the microstructure, hardness, and corrosion resistance of Pb-5%Sb spine alloy. The alloy has been produced by high pressure die casting (HPDC), medium pressure die casting (AS) and low pressure die casting (GS) methods, respectively.
The microstructure was characterized by using optical microscopy and scanning electron microscopy (SEM).
Postlethwaite and Freese  studied the effect of halide ions on the anodic behaviour of pure nickel in S solutions and observed that all the halides accelerate the dissolution in active state and can break down the passive.
This paper investigates the microstructures and the polarization behaviors of AlCrFe35Mn20Ni15 high-entropy alloy in 1M (1 mol/L) deaerated sulfuric acid (H2SO4), nitric acid (HNO3), and hydrochloric acid (HCl) solutions at temperatures of 30–60 °C. The three phases of the AlCrFe35Mn20Ni15 high-entropy alloy are body-centered cubic (BCC) dendrites, face.
