The corrosion rate in the active region beneath the oil-covered sodium chloride...

... corrosion may proceed only if specific conditions are met (e.g., temperature and potential should be above the critical values for each alloy). The classical approach for assessing the occurrence of localized corrosion in service conditions is by laboratory testing at a constant temperature. Thus...

.... However, the airframe is also exposed to a spectrum of environmental conditions including variations in temperature, humidity, atmospheric gas composition, salt concentration, pollution, and ultraviolet light exposure which tend to degrade structural capabilities over time. The detrimental influence...
