Other mechanisms of introduction of hydrogen into metal are galvanic corrosion, as well as chemical reactions with acids or other chemicals.
32.
The inventory also found premature deterioration of its supports due to galvanic corrosion involving the steel bearing pads and aluminum girder structure.
33.
To prevent galvanic corrosion between the copper skin and the iron support structure, Eiffel insulated the skin with asbestos impregnated with shellac.
34.
In a special case, micropores can help distribute the electrochemical potential that accelerates galvanic corrosion between the layers of nickel and chromium.
35.
Alloy wheels are prone to galvanic corrosion, which can cause the tires to leak air if appropriate preventive measures are not taken.
36.
If the aluminum foil only touches the electrolyte in small areas, the galvanic corrosion is concentrated, and corrosion can occur fairly rapidly.
37.
Drilling the corroded fasteners out and replacing them with aluminum pop-rivets will stop the galvanic corrosion before it has a chance to spread.
38.
Factors such as relative size of anode, types of metal, and operating conditions ( temperature, humidity, salinity, etc . ) affect galvanic corrosion.
39.
If the application of corrosion inhibitors increases the conductivity of the water within the system, the galvanic corrosion potential can be greatly increased.
40.
The increasing use of carbon fiber composites is displacing aluminum from aerospace applications in favor of other metals because of galvanic corrosion issues.
