Electrolytic corrosion occurs when metal surfaces are exposed to an electrolyte and an electrical current, causing the metal to deteriorate through an electrochemical reaction. This process is accelerated by the presence of dissimilar metals, leading to galvanic corrosion, and can be mitigated by using insulating materials or cathodic protection techniques.

Electrolytic Corrosion

Metal surfaces

Electrolytes are substances that dissociate into ions when dissolved in water, enabling them to conduct electricity. They are crucial for numerous physiological functions, including nerve impulse transmission and muscle contraction, and are essential in maintaining the body's fluid balance.

Electrolyte

Electrical current is the flow of electric charge, typically measured in amperes, which moves through a conductor due to a potential difference. It is a fundamental concept in understanding how electrical circuits function, enabling the operation of electronic devices and systems.

Electrical Current

Metal Deterioration

An electrochemical reaction involves the transfer of electrons between a chemical species and an electrode, driving the conversion of chemical energy into electrical energy or vice versa. These reactions are fundamental to processes like corrosion, energy storage in batteries, and electroplating, and are governed by principles of thermodynamics and kinetics.

Electrochemical Reaction

Dissimilar Metals

Galvanic corrosion occurs when two dissimilar metals are in electrical contact in a corrosive environment, leading to the more anodic metal corroding faster than it would alone, while the cathodic metal is protected. This phenomenon is driven by the electrochemical potential difference between the metals, which causes a galvanic cell to form, accelerating corrosion processes.

Galvanic Corrosion

Insulating materials are substances that reduce the rate of heat transfer, enhancing energy efficiency and thermal comfort in buildings and devices. They work by minimizing conduction, convection, and radiation, often utilizing air pockets or reflective surfaces to achieve their insulating properties.
