Dealloying – Dealloying (also referred to as selective leaching) is the selective removal of one element of a solid alloy by a corrosion process. A corrosive medium specifically attacks one component of the alloy. A common example of this type of corrosion is the selective removal of zinc from brass (dezincification)
