What meant by corrosion?

Corrosion is the deterioration and loss of a material and its critical properties due to chemical, electrochemical and other reactions of the exposed material surface with the surrounding environment. Corrosion of metals and nonmetals takes place due to the gradual environmental interaction on the material surface.

What is meant by corrosion 1 point?

1 Definitions of corrosion. Corrosion is generally taken to be the wastage of a metal by the action of corrosive agents. However, a wider definition is the degradation of a material through contact with its environment. In high-temperature oxidation the metal ion becomes part of the lattice of the oxide formed.

What is corrosion explain with 2 examples?

Corrosion is defined as the degradation of metals due to an electrochemical process. In this process metals are converted into more stable compounds such as metal oxides, metal sulfides, or metal hydroxides. Examples of corrosion: Rusting of iron. Crevice corrosion in aluminium alloys and stainless steels.

What is corrosion class 9th?

Corrosion is a natural process in which a refined metal is converted to a more chemically stable form, such as oxide, hydroxide, or sulphide. It is the gradual decomposition of materials (usually metals) as a result of chemical and/or electrochemical reactions with their surroundings.

What is corrosion class 10 Brainly?

Brainly User. Corrosion is the process in which metals are eaten up gradually by the action of air, moisture or a chemical in their surface.

What is corrosion with Example Class 10?

The gradual eating up of metals by action of air, moisture or a chemical reaction (such as an acid) on their surface is called corrosion. The most commonly seen example of corrosion of metals is rusting of iron i.e the formation of a brown flaky substance on iron objects on exposure to moist air.

What is corrosion Class 10 SSC?

Solution 1. Corrosion is the damage caused to the metal by the chemical reaction of air, water and acids with the surface of the metal.

What is corrosion class 7th?

Corrosion is a process where the metal corrodes. Corrosion is a natural process and in the presence of a moist atmosphere, chemically active metals get corroded. Corrosion is a process where the water or the moisture on the surface of the metal oxidizes with the atmospheric oxygen, it is an oxidation reaction.

What is corrosion and what does it mean?

What Does Corrosion Mean? Corrosion is the deterioration and loss of a material and its critical properties due to chemical, electrochemical and other reactions of the exposed material surface with the surrounding environment. Corrosion of metals and nonmetals takes place due to the gradual environmental interaction on the material surface.

What is the resistance of metal to corrosion?

Resistance to corrosion. Some metals are more intrinsically resistant to corrosion than others (for some examples, see galvanic series ). There are various ways of protecting metals from corrosion (oxidation) including painting, hot dip galvanizing, and combinations of these.

What are the factors that affect corrosion?

Factors Affecting Corrosion 1 Exposure of the metals to air containing gases like CO 2, SO 2, SO 3 etc. 2 Exposure of metals to moisture especially salt water (which increases the rate of corrosion). 3 Presence of impurities like salt (eg. 4 Temperature: An increase in temperature increases corrosion.

Is corrosion an electrochemical or electrochemical process?

Corrosion can be classified as an electrochemical process since it usually involves redox reactions between the metal and certain atmospheric agents such as water, oxygen, sulphur dioxide, etc.
