Hydrogen embrittlement caused by disaster: Hydrogen is silent, but once it is associated with metal, it can cause disaster. Eighty years ago, 1,500 oil tankers at the Swan Island shipyard in the United States had serious cracks, and a thrilling scene was staged.
The expensive tanker broke in two before the test was tested, sparking speculation about mysterious powers, like a bizarre story. However, the truth is revealed, and the culprit is actually a common chemical element - hydrogen. Historically, hydrogen embrittlement incidents have occurred in aviation, petroleum, chemical industry, nuclear energy and other fields, causing major accidents and leaving a profound lesson for people.
The root cause of hydrogen embrittlement is the infiltration of hydrogen and the reaction of metals, resulting in embrittlement of materials. However, scientists are not helpless, and they have worked tirelessly to find the best way to avoid hydrogen embrittlement, and they have achieved some exciting results. How to prevent and solve the problem of hydrogen embrittlement has become an urgent problem to be solved in the industrial field.
What is the nature of the hydrogen embrittlement phenomenon?The cause of this phenomenon is the chemical reaction between hydrogen and metal, which makes the metal material fragile and breakable. Hydrogen is one of the simplest elements in the periodic table, but when it penetrates into the metal lattice, hydrides are formed, making the metal brittle and increased.
Hydrogen embrittlement generally occurs between -50 and 100, and once hydrogen penetrates into the metal, it is easy to cause sudden cracks and **, causing serious safety hazards. This phenomenon has occurred in many serious accidents in history, causing huge losses to industrial production and people's lives and property. How to avoid hydrogen embrittlement in modern industry?
Steelmakers have found through their long-term production experience that it is important to avoid using metals that easily react with hydrogen, and to choose stable metal materials. In addition, a dehydrogenation process can be carried out after the metal is finished, by heating the metal to a certain temperature to expel most of the hydrogen to ensure that the metal is no longer latent in hydrogen.
In addition, scientists are also working to find new materials that are not affected by hydrogen embrittlement, such as using a mixture of carbon and metal, which can effectively reduce the damage of hydrogen to metals. Modern industrial sites will also use special air control systems to keep the gas concentration stable and provide an invisible safety barrier for industrial production.
The development history and countermeasures of hydrogen embrittlement: Although hydrogen plays an important role in life, once it triggers hydrogen embrittlement, it can lead to disaster. Historically, hydrogen embrittlement incidents have occurred constantly, triggering a number of major accidents. However, scientists are not helpless, and their tireless efforts have led to some exciting results.
How to prevent and solve the problem of hydrogen embrittlement has become an urgent problem to be solved in the industrial field. Therefore, we urgently need to strengthen the research on hydrogen embrittlement and find more solutions to ensure the safety and stability of industrial production. What do you know about the phenomenon of hydrogen embrittlement?In modern industrial production, how should we better avoid the occurrence of hydrogen embrittlement?
