protection against corrosion

Reading time:

Means for fighting corrosion include :

  • the use of metallic (see galvanised steel) but more commonly organic (paint, ebonite) or even mineral (cast iron coated with cement mortar) coatings for providing physical insulation …
  • the chemical properties of water are kept to levels that slow corrosion down as much as possible;
  • corrosion inhibitors are added to the water
  • the use of electrochemical potential, either via a sacrificial material or from external sources (cathodic protection).
