This is the eating away and eventual destruction of metals and alloys by chemical attack. The rusting of iron and steel is the most common form of corrosion. The iron combines with oxygen and water to form the brown orange deposit we know as rust (hydrated iron oxide).

Corrosion is also a problem between electrical connections. For this reason, connecting blocks are often sealed, to prevent the ingress of liquids.

Ways to combat corrosion:

  • Corrosion can be combated by the application of paint and sprays. 
  • Use alloys that are less prone to corrosion. For example, in connector blocks for electronic engine managment, gold or nickel plated connectors are used. 
  • Store machinery indoors, or under cover, when it’s not in use.
