Reasons for rust of extended data

1, the influence of relative humidity The higher the relative humidity in the air, the thicker the water film on the metal surface, and the oxygen in the air acts on the metal surface through the water film. When the relative humidity reaches a certain value, the corrosion rate increases greatly, which is called critical relative humidity. The critical relative humidity of steel is about 70%. ?

2. The influence of temperature?

Ambient temperature is related to relative humidity. In a dry environment (desert), metals do not rust easily at high temperature. When the relative humidity reaches the critical value, the influence of temperature is obviously intensified, and the corrosion rate is doubled when the temperature rises by 65438 00℃. Therefore, in the humid and hot zone or rainy season, the higher the temperature, the more serious the corrosion. ?

3. The effect of oxygen?

It can be seen that without water and oxygen, metals will not rust, and 20% of the air is oxygen, which is pervasive. ?
