Group 16. Aaron Salazar. Phillip Schneider. Kevin Stacy. Geoffrey . Thiel. Sections 16.2 – 16.6. Electrochemistry. OF . CORROSION. The huge annual loss due to corrosion is a national waste and should be minimized. Materials already exist which, if properly used, can eliminate 80 % of corrosion loss. Proper understanding of the basics of corrosion and incorporation in the initial design of metallic structures is essential. What is corrosion?. A) The reaction of a metal with oxygen in the air, moisture or other substances in the environment is called . corrosion. . . B) Gold is so . unreactive. that it does not corrode at all.. _ Two methods of combating corrosion which are widely used in Ne metal surface, and this can be monitored by measuring the potential of the metal. The conditions needed to stop corrosion can then be Corrosion. Corrosion-An . oxidization. of a metal, and the oxide flaking off.. Oxidized metal is commonly called rust. Most commonly oxygen will oxidize a metal.. Either by . [Metal] + O. 2. . → . Ores, Alloys, Corrosion and Smelting. ORES. An . ore is a rock or mineral that a useful metal can be removed from..  . Some metals are found free in nature. These include iron, copper, . lead, and aluminum.. Please check your headphone and microphones and adjust them for sound levels.
