Is Hydrogen Gas Corrosive
"On the Corrosive Properties of Hydrogen"
Those who discuss the physical properties of the world have many difficulties in the corrosive properties of hydrogen. Hydrogen is light, colorless and odorless, and always exists between heaven and earth. However, there are different opinions on its role in matter.
Or hydrogen is corrosive. Looking at all kinds of metals, in the hydrogen-containing environment, it will change over time. For example, iron in a hydrogen-rich atmosphere gradually rusts, which seems to be eroded by hydrogen. The activity of hydrogen can chemically react with metals, breaking their structure and causing gradual changes in the quality of metals. And hydrogen atoms are tiny, which can penetrate into the metal lattice, causing the lattice to distort and reduce the mechanical properties. This is also a sign of corrosion.
However, there are also dissenters. He said that hydrogen is very stable under normal conditions, unlike strong acid and alkali, and immediately shows the effect of corrosion. Without special conditions, such as high temperature, high pressure or the existence of catalysts, hydrogen is difficult to react violently with other things. Metal changes, or due to the presence of other things in the environment, are not caused by hydrogen alone. And in some scenarios, hydrogen is not only non-corrosive, but also has protective properties. For example, during metal heat treatment, hydrogen can prevent metal oxidation.
In summary, the corrosiveness of hydrogen cannot be generalized. It depends on the specific situation and conditions. High temperature and high pressure, with the help of catalysis, hydrogen is fully active and the risk of corrosion is greatly increased; while in a normal and peaceful environment, its corrosion is not obvious, or it has a different effect. Therefore, to understand the influence of hydrogen on things, it is necessary to study the state in detail to obtain its true meaning.
