The phrase "accelerate the corrosion process" is correct and usable in written English.
It can be used in contexts discussing materials science, chemistry, or environmental science, particularly when referring to factors that speed up the deterioration of materials.
Example: "The presence of saltwater can significantly accelerate the corrosion process in metal structures."
Alternatives: "speed up the corrosion process" or "hasten the corrosion process".
However, cracks provide quick access to chloride, oxygen and water into concrete and accelerate the corrosion process.
Lower pH value may break the protective film also known as passive film of steel and accelerate the corrosion process.
To accelerate the corrosion process during a reasonable time, experiments were carried out by exposing ductile iron and carbon steel to soils of six different chloride concentrations at the temperature 40 °C for 3 months.
Two different accelerated corrosion tests (14 cycles of dry/wet alternated corrosion tests and long-term immersion tests) were carried out to accelerate the corrosion process.
In order to clarify the effects of chloride ions and accelerate the corrosion process, different amounts of sodium chloride were mixed into the distilled water and then evenly dispersed into the soil samples, thus resulting as six soil samples of separate chloride contents, i.e. 0.015%, 0.065%, 0.115%, 0.315%, 0.515%, 1.015% (wt.%).
Different corrosion distributions along rebar length were simulated using a sodium chloride pond with various sizes set on the concrete cover, and a direct current was applied to accelerate the corrosion process.
Asami et al.13 verified the major accumulation of β-FeOOH in the thick parts of rust layers that served as a Cl− container; β-FeOOH made the layer more porous and accelerated the corrosion process as well.
After burying the coupons into soils, each reactor was sealed using the plastic cover and the silica gel 704; then they were stored in the constant temperature incubator at 40 °C, which was intended for accelerating the corrosion process according to the Environmental Acceleration Method26.
Results indicate that a small amount of Al (2 5 wt.%) is advantageous to mitigate the corrosion of the commercial Ni-base alloy, whereas further increase of Al content (8 10 wt.%) accelerates the corrosion process.
Glutamic acid can act as an efficient corrosion inhibitor, but it can in other cases show an opposite effect, which accelerates the corrosion process; all depend on the experimental conditions.
