What is corrosion? - The deterioration of a metal or alloy that results from an electrochemical reaction with its environment. What needs to be present in order for corrosion to occur? - Anode Cathode Metallic Pathway Electrolyte What is an anode? - The anode is the area of the metal surface that corrodes. The metal oxidizes (gains oxygen), causing it to lose mass and dissolve into the electrolyte. What is oxidation? - Oxidation is a chemical reaction that occurs at the anode where the m...

Describe passivation - ANSWER-Passivation is the formation of a protective oxide Film on the surface reducing its chemical activity and its ability to corrode Describe the following factors and how they affect corrosion - ANSWER-Oxygen: oxygen increases the rate of corrosion temperature Temperature: corrosion usually accelerated with increasing temperature Chemical salts: increase the rate of corrosion by increasing the efficiency of the electrolyte humidity: the wetter the environment,...
