Corrosion Glossary - Z

  • Zeolite: A group of hydrated sodium aluminosilicates, either natural or synthetic, with ion exchange properties. (See gel zeolite, greensand.)
  • Zinc plating: the electro-deposition of zinc or zinc alloys (eg Zn/Ni, Zn/Sn) to provide galvanic corrosion protection.
  • Zone of aeration: the layer in the ground above an aquifer where the available voids are filled with air. Water falling on the ground percolates through this zone on its way to the aquifer.
  • Z-mill: common name for a Senzimir multiple-backup cluster mill used for cold-rolling stainless and carbon steel sheet or strip to very precise dimensions and fine finishes.
  • Zone of saturation: the layer in the ground in which all of the available voids are filled with water.
