Which of the following expression is used for electrochemical techniques to determine the corrosion penetration rate?

Which of the following expression is used for electrochemical techniques to determine the corrosion penetration rate? Correct Answer Corrosion penetration rate = K (ai/nD)

The corrosion rate expression that is used for electrochemical techniques to determine corrosion penetration rate is K (ai/nD) where a is the atomic weight of the metal, i is current density (in microamperes per sq. centimeters), n is the number of electrons lost, D is the density of metal, K is constant depends on the penetration rate desired.

Corrosion of less corrosion-resistant metal is usually increased and the attack of the more corrosion-resistant is decreased in galvanic corrosion.
Permeability in concrete is studied towards providing for, or guarding against, which of the following features? 1. The penetration by materials in solution may adversely affect the durability of concrete; moreover, aggressive liquids 'attack' the concrete. 2. In the case of reinforced concrete, ingress of moisture and air will result in corrosion of steel leading to an increase in the volume of steel, resulting in cracking and swilling of the concrete cover. 3. The moisture penetration depends on permeability and if the concrete can become saturated with water it is less vulnerable to frost action.
