“…2 (1) Historically, severe environments have been used for corrosion testing of aircraft aluminum alloys. Many of the standardized corrosion tests for AA2024-T3 (UNS A92024) (1) currently in use involve concentrations of chloride between 0.5 M and 1.0 M. 3 These solutions are intended to accelerate the corrosion that occurs during service to produce laboratory samples for mechanical testing in a short time. However, some of these tests may result in a corrosion topography that is different from that observed on aircraft in the field.…”

The aging of aircraft fleet has led to significant concern about the development of corrosion. Occluded regions such as lapsplice joints, which are difficult to inspect, are of particular importance. By analyzing the corrosion products found in these joints, a simulant solution has been developed. The lap joint simulant solution (LJSS) contains 20 mM sodium chloride (NaCl), 4 mM sodium bicarbonate (NaHCO 3 ), 4 mM sodium nitrite (NaNO 2 ), and 2 mM sodium fluoride (NaF) at pH 9. Exposure of AA2024-T3 (UNS A92024) to the LJSS results in a similar corrosion topography to that found on aircraft in the field.

“…The nominal composition of the test samples are given in Table 2, which also shows the materials of construction, product forms, and thickness for sheet or diameter for wire mesh. Weight losses were used to calculate the corrosion rate (CR) using the following general formula [2]: CR = {(Constant)(Weight Loss)} / {(Density)(Surface Area)(Time)}. Equation (1) For perforated sheet, Equation 1 was used without further derivation.…”

Short time corrosion testing of perforated sheets and wire meshes fabricated from Type 304L stainless steel, Alloy 600 and C276 showed that 304L stainless steel perforated sheet should perform well as the material of construction for dissolver baskets. The baskets will be exposed to hot nitric acid solutions and are limited life components. The corrosion rates of the other alloys and of wire meshes were too high for useful extended service. Test results also indicated that corrosion of the dissolver should drop quickly during the dissolutions due to the inhibiting effects of the corrosion products produced by the dissolution processes.
