The corrosion rate of mild steel in low corrosive tap water in the absence and presence of 1hydroxy ethane-1, 1-diphosphonic acid (HEDP) and calcium gluconate have been evaluated by weight loss, electrochemical polarization and AC impedance measurements. Presence of calcium gluconate considerably enhanced the corrosion inhibition efficiency of the widely used water treatment agent HEDP. At high...

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...

Corrosion inhibition behavior of Ascorbic acid (AA) vitamin C and Thiamine (Th) vitamin B1 on mild steel corrosion in 0.5 M HCl was investigated at various immersion times. The electrochemical characteristics of mild steel in absence and presence of the inhibitors were verified by the cyclic voltammetry method. The protective properties of the passive film were acquired by electrochemical imped...

The inhibition of corrosion on mild steel in 1M H2SO4 by a heterocyclic compound namely cefuroxime axetil has been studied by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy methods. The adsorption characters of the inhibitor on mild steel, free energy change and energy of activation of the inhibition process have been calculated from the results. The inhibi...

A mortality study was carried out in conjunction with the European mortality study among welders coordinated by the International Agency for Research on Cancer (IARC). The study was aimed at assessing risks for lung cancer in relation to exposure to asbestos, welding fumes containing chromium and nickel, and tobacco smoke. The study included a cohort of 2721 welders and an internal comparison g...

The influence of 3-methyl-2,6-diphenyl piperidin-4-one (MDPO) and 2phenyl decahydroquinoline-4-one (PDQO) synthesised in the laboratory on hydrogen permeation and corrosion inhibition of mild steel in 1N H2SO4 has been studied using weight loss and various electrochemical AC and DC corrosion-monitoring techniques. Both the compounds inhibit the corrosion of mild steel in H2SO4. Potentiodynamic ...

This paper presents a study to evaluate the mechanical properties of commercially available GRP composite fasteners for the fairing band assembly components of the hull mounted sonar domes on Canadian frigates. The study was undertaken as part of an effort to develop an all-composite fairing band assembly for a stainless steel sonar dome, to eliminate corrosion problems that occur with the use ...

Chrysoidine dye was examined as an inhibitor for mild steel in 1N HCl using weight loss, gasometric and thermometric methods. Parameters such as inhibition efficiency and corrosion rates were evaluated. The inhibition efficiency was found to increase with increase in the inhibitor concentration. To study the adsorption of the inhibitor on the mild steel surface, adsorption isotherm was plotted.

Piperazine and its derivatives such as phosphates, carbonates, benzoates, cinnamate and maleate were developed and investigated as vapor phase corrosion inhibitors by weight loss, potentiodynamic polarization methods for mild steel. All of these compounds have shown good inhibition efficiency for mild steel after 30 days under continuous condensation test (CT). The potentiodynamic polarization ...

Nano-films consisting of an alternating sequence of positively and negatively charged polyelectrolyteshave been prepared by means of the electrostatic layer-by-layer sequential assembly technique on mildsteels. The mild steels were pretreated electrochemically to modify the mild steel surface. The modificationof the mild steel surface resulted in increasing the adhesion of the obtained nano-fil...
