corrosion environment的意思|示意

Corrosion environment，also known as corrosive environment, can be further divided into four parts: atmosphere, surface water, underground water, and soil.

【Atmosphere】

The atmosphere mainly refers to the presence of moisture, oxygen, acid and alkali gases, dust, radiation, and other factors in the air. These easily cause corrosion of metals and alloys, thereby damaging their physical and chemical properties.

【Surface water】

Surface water refers to the presence of acid and alkali in aquatic bodies such as rivers, lakes, and oceans. Under the action of such solutions, metal or alloy corrosion can easily occur. In addition, the presence of bacteria and microorganisms in surface water can also cause corrosion.

【Underground water】

Underground water is also an important carrier of corrosion. It is mainly caused by the dissolution of acid, alkali, and gases. The corrosion rate of underground water is slower than that of surface water, but it can also cause considerable metal and alloy corrosion.

【Soil】

Soil refers to the aggregate of sand, soil, stone, and organic matter. The main cause of metal and alloy corrosion in the soil is the presence of acid, alkali, and oxygen. If there are more reactive ions in the soil, metal and alloy corrosion can be more intense.

To summarize, corrosion environment refers to the environment in which metal or alloy corrosion can easily occur due to the presence of acid, alkali, oxygen, microorganisms, and other factors. It is important to understand the nature of the corrosion environment, as it can help us better protect metal and alloy materials from corrosion.
