Chipping or chip, Corrosion, Surface Corrosion, Dissimilar metal corrosion, Stress corrosion, Fretting corrosion - Basic Aircraft Engine Inspection. Impressed Current Cathodic Protection System. Corrosion is a complex electro-chemical action that causes metals to be transformed into their salts and oxides. Material Selection; Coatings; Cathodic Protection; Chemical Corrosion Inhibitors. Where an area of unprotected metal is exposed to an atmosphere containing battery fumes, exhaust gases, or industrial contaminants dulling of the surface is caused by corrosion salts. Throughout history, metals have had a decisive effect on human civilization, and they largely condition the way we live today. Group 1 metals are very reactive. Metal atoms lose electrons to form positive ions. Introduction, Mechanism and Types of Corrosion. Corrosion – a redox reaction that take places between a metal and the gases in air. Corrosion, Metal corrosion is the deterioration of the metal by chemical or electrochemical attack, water of water vapor containing salt combined with oxygen in the atmosphere produce the main source of corrosion in engines. These powdery substances replace the metal and cause severe loss of strength in the structure. Corrosion inhibitors usually react with the surface of the metal to form a protective surface film, either in the form of an adsorbed layer of inhibitor, or a chemical conversion product. Uniform corrosion also intends to the corrosion that advances almost at the same rate all over the metal surface. Metal is oxidised to form an oxide layer on the surface.
