Factors Influencing Corrosion
Various factors influencing the corrosion of any material are,
Position of Metals in Electrochemical Series: In corrosion, the electrochemical series is extremely important. Reactive metals lose electrons more quickly and corrode more quickly. Iron, for example, is quickly oxidised, but gold is not because gold is less reactive than iron.
Impurities in Metals: In general, the presence of contaminants in metals accelerates corrosion because these impurities operate as the microscopic electrochemical cell that causes corrosion.
Presence of Electrolytes: Because they carry ions, dissolved salt in water acts as an electrolyte. Corrosion is accelerated when electrolytes are present in water.
Concentration of Oxygen: Corrosion is accelerated by an increase in oxygen content. An anode is a location with less oxygen concentration, whereas a cathode is a region with a higher oxygen concentration. Corrosion happens as a result.
Humidity in Weather: When the weather is humid, the presence of moisture with a high temperature accelerates corrosion because ions gain energy and begin moving quicker in a higher temperature, causing them to collide more frequently.
Temperature: The rate of Corrosion increases with temperature.
Corrosion
Corrosion is a chemical phenomenon that we observe regularly in our daily life. Corrosion occurs in metal and in corrosion reaction metal react with air and moisture from the surrounding to form the more stable compounds of the atom that include oxides and hydroxides.
Generally, rusting of iron is also an example of corrosion as rusting iron reacts with oxygen and moisture from the air to form iron oxide (rust). Corrosion reactions of various metals can be easily achieved by allowing the metal to react freely with moist air. In this article, we will learn about, Corrosion, its types, examples and others in detail.
