The phrase "amounts of corrosion" is correct and usable in written English.
It can be used when discussing the quantity or degree of corrosion present on a material or surface.
Example: "The engineer noted that there were significant amounts of corrosion on the metal beams, which could compromise the structure's integrity."
Alternatives: "levels of corrosion" or "degrees of corrosion".
"Today we visibly observed a significant amount of corrosion at the bottom of the pipeline," Mr. Holloway said.
The maximum amount of corrosion of 13.25% and the dilation crack width of 1.2 mm were two important critical parameters.
Just a few days before, BP, the world's second-largest oil company, had revealed that it had discovered a dangerous amount of corrosion on a 16-mile feeder line to the Trans-Alaska Pineline in Prudhoe Bay.
Increasing both temperature and exposure duration led to an increased amount of corrosion as measured by the cross-sectional area loss of the corroded refractory specimen.
The main parameters examined were the amount of corrosion penetration in the wall thickness, its extent along the pipe, the type and number of the CFRP sheets.
The results showed that the flexural strength, the circular stiffness, the ductility, and the energy absorption of corroded RC column degraded with the increase of the maximum amount of corrosion of rebar.
The strength of a beam deteriorated by rebar corrosion could be recovered using HPFRCC patching if the amount of corrosion was less than 10%.
This study demonstrates that the IBS scaffold with novel design has significantly shortened corrosion period and less amount of corrosion products without causing any biological problems after implantation up to 13 months, therefore is promising for coronary application.
The traditional soaking method was replaced by a new wrapping method in order to obtain the desired amount of corrosion of rebar that was similar with the environment condition.
