The vents are also subjected to particularly demanding environmental conditions, for example, a hail test, a salt-spray test that simulates coastal conditions, and tests to simulate the corrosive gases found in smog and acid rain.
After completion of the salt-spray test protocol, test samples were removed from the Ascott chamber, and the chamber was set to complete five automated clean and purge cycles to remove potential NaCl contamination.
The most recently developed salt-spray test plans are cyclical and include both dry and wet time periods.
The corrosion resistance performance rating as per salt-spray test has been used as response and the optimizations of factors have been worked out using STATGRAPHICS[R] Centurion XV (Statpoint Inc.) and Minitab 15 (Minitab Inc.) software.
For correlation with salt-spray test, 5% NaCl solution in DI water was used as electrolyte (pH-6.6-6.8).
Table 1 shows the results of water boiling test and salt-spray test for various ureasil-based pretreatments and also for commercial systems.
ASTM B117 salt-spray test is a standard lest to determine resistance of films to corrosion under accelerated conditions.
Salt-spray test results showed very interesting trend.
Alodine 1200 S showed very well-defined passivation in the range of -1.0 V to -600 mV and also showed fading/loss of color in the salt-spray test. This can be attributed to the release of chromium (VI) compounds due to their solubility in water.
After application onto AA 2024 T3, panels were cured at room temperature for 7 days and tested for field corrosion performance in salt-spray test for 3 weeks.
And in the ASTM B-117 salt-spray test, plating with Micro Tuff lasted 530 hr vs.
Salt-spray tests, according to DIN EN ISO 9227:2006, indicated performance of more than 10,000 hours without corrosion.
