The adsorption isotherm and corrosion inhibition mechanism were put forward. The concentrated sulfuric acid, absolute ethyl alcohol ... OCP at a scanning rate of 0.5 mV/s. All the electrochemical ...

And they are developing corrosion-resistant replacement ... (parts-per-million levels) of boric acid to the coolant water to help control the fission rate. They balance the pH by adding lithium ...

The specimens were cleaned for 30 min in chromic acid solution (180 g/l) at room temperature then washed with ethanol and finally dried in hot air to remove the corrosion products. The corrosion rates ...

The rate at which the corrosion process progresses depends on a number of factors ... as well as soluble salts to produce an acceptable surface condition for painting. Acid pickling involves immersing ...

Then there are cases of water ingress due to corrosion from scrubber waste. "We have seen a few incidents where within 10 to 15 months of the open-loop scrubber being installed, corrosion of the ...

In addition to being corrosive itself, hydrochloric acid is a catalyst for corrosion ... active corrosive agents in refineries. High-corrosion rates for these elements, however, often require ...

Flow-induced wall shear stress can separately affect the corrosion rate by both naphthenic acid and sulfur species. Areas of high turbulence and refinery units with process stream flow velocities ...
