| 21. | As with other metals, if copper is put in contact with another metal, galvanic corrosion will occur.
|
| 22. | Mirrors use a small amount of copper to provide galvanic corrosion protection to the reflective silver layer.
|
| 23. | Having dissimilar metals in contact can result in galvanic corrosion inside of the lamps'sockets, causing them to stop working.
|
| 24. | When the silver reaches the aluminium, an electric short circuit forms, and galvanic corrosion then rapidly degrades the reflective layers.
|
| 25. | Dielectric unions, with dielectric insulation, separate dissimilar metals ( such as copper and galvanized steel ) to prevent galvanic corrosion.
|
| 26. | This is an example of cathodic protection, an electrochemical technique developed in 1824 by Humphry Davy to prevent galvanic corrosion.
|
| 27. | By utilizing lower concentrations of sodium molybdate, conductivity is kept at a minimum and thus galvanic corrosion potentials are decreased.
|
| 28. | The presence of an electrolyte and an electrical conducting path between the metals is essential for galvanic corrosion to occur.
|
| 29. | The oxides on the surface of aluminium cause wetting issues and special solders must be used to prevent galvanic corrosion issues.
|
| 30. | As a result, galvanic corrosion can occur in the presence of an electrolyte, and these connections can become unstable over time.
