Chinese researchers have developed a versatile graphene-based anti-corrosion coating that provides better, cheaper protection.
How corrosion inhibitors protect metal: synthesis in the lab and testing
The problem of corrosion is very relevant for infrastructure, buildings and equipment in areas with a harsh climate. For example, in the coastal zone and on the islands of the China Sea, concrete structures begin to collapse in less than 3 years, metal equipment ceases to function after about a year, artillery structures fail three months later due to rust. In 2014 The Celestial Empire has spent $ 300 billion just to fight corrosion of fighters, ships, missiles and other weapons..
Therefore, scientists from the city of Ningboali are effective coverage, which is cheaper than the options available on the market with an average cost of 5.5 to 8.7 dollars per 1 kg. At the moment, a military research institute in Shanghai is conducting its final tests..
High temperature, humidity, fog, air and solar radiation..
Although the graphene coating has not yet been used for military purposes. It is very useful in industry to protect pipelines from acid corrosion, high pressure and strong position..
Used to accelerate corrosion due to increased flow of electric current. Therefore, graphene must be mixed with other substances that reduce conductivity..
The production lines are currently operating at full capacity to meet the demand for a new anti-corrosion material.. Its future versions are a way to improve the stealth of fighters and aircraft carriers..
Scientists have recently found a way to reduce the cost of graphene 200 times..
