Since the contacts of the reed switch are sealed away from the atmosphere, they are protected against atmospheric corrosion.
2.
Brass, an alloy of copper and zinc, has good resistance to atmospheric corrosion, alkalis, and organic acids.
3.
This ullage or headspace area contains more oxygen and thus speeds atmospheric corrosion, as evidenced by the appearance of rust scales.
4.
The final patina is a particularly durable layer that is highly resistant to atmospheric corrosion, thereby protecting the underlying metal against further weathering.
5.
It is usually less than thick and initially adheres to the steel surface and protects it from atmospheric corrosion provided no break occurs in this coating.
6.
"Weathering " refers to the chemical composition of these steels, allowing them to exhibit increased resistance to atmospheric corrosion compared to other steels.
7.
The final sulfate patina is a particularly durable layer that is highly resistant to all forms of atmospheric corrosion and protects the underlying metal against further weathering.
8.
The lack of correlation between results obtained from traditional salt spray testing and the real world atmospheric corrosion of vehicles, left the automotive industry without a reliable test method for predicting the service life expectancy of their products.
9.
Their subsequent tests also revealed that far from decreasing the rate of corrosion, glass bead peening may in fact increase the rate of atmospheric corrosion since it increases the surface area allowing for more areas to contain particles and water.
