1.	What are the factors that affect Galvanic coupling?(a) Type of metals(b) Relative size of electrodes(c) Environmental conditions(d) Types of metals, the relative size of electrodes and environmental conditionsThe question was posed to me in class test.The question is from Principles topic in portion Corrosion Principles of Corrosion Engineering
Answer» RIGHT answer is (d) Types of metals, the relative size of electrodes and environmental conditions Best explanation: Metal combinations used for GALVANIC contact will affect based on the potential difference between them. Relative size of electrodes, environmental conditions such as TEMPERATURE, HUMIDITY and salinity alter the chemical KINETICS of the reaction.
