Casting Metal
Cathode	The cathode in an electrochemical cell is the site where electrons are consumed. For each electron that is produced at an anodic site, an electron must be consumed at a cathodic site. No metal loss occurs at sites that are totally cathodic.
Cathodic Protection	Cathodic protection prevents corrosion by making a metal, which would ordinarily behave like an anode and corrode, behave like a cathode and be free from corrosive attack. In cathodic protection this is achieved by providing electrons of a higher energy level (electric potential) than those which would be produced in the corrosion reaction at the anode.
Cathodic Reactions	The electrons that are produced at anodic sites are consumed at cathodic sites.
Cavitation corrosion	Cavitation corrosion is corrosion that is enhanced through the formation and collapse of gas or vapor bubbles at or near the metal surface
Cleaning	The Care and Cleaning of Stainless Steel
	Pickling and cleaning of stainless steel

Concentration cell corrosion	Concentration cell corrosion is corrosion that is accelerated by differences in environment between separated areas on a single metal
Corrosion fatigue	Corrosion fatigue is the reduced ability of a metal to withstand repeated stress when exposed to the combined action of stress and a corrosive environment as compared to the effects of stress alone
Crevice Corrosion	Crevice Corrosion can be thought of as a special case of pitting corrosion, but one where the initial "pit" is provided by an external feature; examples of these features are sharp re-entrant corners, overlapping metal surfaces, non-metallic gaskets or incomplete weld penetration.
