The results of this work confirm already known data about low corrosion resistance of aluminium alloys in aqueous solution with chloride ions
. Nevertheless, the verification of the urea effect can be considered as contributing for other research (i.e.
Indeed, the breakdown of passive film formed on steel surface at high alkaline pH due to chloride attack in severe load condition and the propagation of localized corrosion, due to local acidification caused by concentrated chloride ions
(0.1M) leading to [Fe.sup.2+] release, does not generate sufficiently energetic AE waves.
The assessment of ternary blended concrete in chloride environment was carried out based on the results obtained from macrocell corrosion study, amount of free chloride content and chloride ion
can be transported through a coating film dissolved in water or by an ion exchange mechanism.
In addition, a correspondingly smaller number of potentially harmful chloride ions
enter the soil when calcium chloride is applied at the specified rate.
will only migrate with moisture, and an effective waterproofing system will help considerably.
Attached to each one of the active sites is a chloride ion
, but as the nitrate ion comes through, it has such a strong affinity to the site that it bumps the chloride off and attaches itself, said McMullen.
Also, the sulfate ion is one-third as aggressive as the chloride ion
The kidneys help control the body's acidity by absorbing filtered bicarbonate ions in exchange for chloride ions
by secreting hydrogen ions.
Some components in gasoline, chloride ions
, formic acid and water, may decompose through auto-oxidation to form aggressive substances that may attack polymers.
There are two forms of chloride ions
in ocean aggregates.
The steel surface enlarged 5K times and holes were found in some places, indicating the passivation film of the reinforcing steel in the simulated concrete pore solution is slowly penetrated by chloride ions
and begins to corrode.
