Which type of. Metal oxide film formation cause rapid corrosion?
A-volatile
B-non. Volatile
C-porous
D-stable
Answers
Answer:
volatile
Explanation:
In the case of volatile metal oxide film formation, as soon as oxide layer is formed it evaporates eating a part of the metal exposing fresh surface of metal for further corrosion. This causes rapid and continuous corrosion leading to severe destruction of metal.
CORROSION
Volatile metal oxide film formation causes rapid corrosion.
CHARACTERISTICS OF CORROSION:
* Corrosion is the degradation of a substance as a result of its interaction with its surroundings. Corrosion is the most common way for metals to corrode. Corrosion eats the material, lowering its load-bearing capacity and generating stress concentrations.
* Corrosion is frequently a significant component of maintenance costs, therefore corrosion control is critical in many designs. Corrosion is described in qualitative words such as whether a material is immune, resistant, sensitive, or highly susceptible to corrosion, rather than in terms of a design attribute value like other characteristics.
* Corrosion is generally electrochemical in nature, with all of the characteristics of a battery. Corrosion is a natural occurrence that happens when unstable materials, such as refined metals, try to return to a more stable state.
