  When it comes to aircraft carriers (referred to as aircraft carriers for short), many people will not be unfamiliar. An aircraft carrier is a symbol of a country's comprehensive national strength and is also essential for building a strong navy. The aircraft carrier is also one of the largest, most complex, and most powerful weapon in the world. We all know that aircraft carriers have very high requirements for decks because they need to take off and land aircraft briefly. So, do military fans understand the production of aircraft carrier deck materials? It is reported that there are only a few countries in the world that can build aircraft carrier decks. How many do you know?

  According to experts, "The deck of the aircraft carrier is made of tungsten alloy impact-resistant high-strength steel plate. This steel plate not only has the characteristics of high strength, high toughness, low temperature resistance, oxidation resistance and light weight, but also has antimagnetic, impact resistance, and friction resistance. , Resistance to high temperature and deformation, and resistance to seawater corrosion. "

  It must be known that the deck material must be able to withstand impact and friction because the carrier-based aircraft weighs tens of tons. When the aircraft takes off and lands, the deck must withstand great impact and friction. More importantly, the aircraft carrier was originally designed for warfare. Of course, it must be sufficiently strong to resist impact to meet the requirements of bulletproof, that is, defensive capabilities. Taken together these requirements, the strength of the steel used must be above 850 MPa. And the deck is as large as several football fields. So, which countries in the world can make aircraft carrier steel?

  

  At present, Russia, the United States, China, France, and Japan can produce steel for aircraft carriers! At present, China has also independently developed aircraft carrier steel plate materials, and has also successfully developed a rolling mill suitable for aircraft carrier steel plate size. The width of the rolled steel plate can reach 5.5 meters and the rolling length can reach more than 40 meters! There are only 5 such tungsten-alloy high-strength steel plates that can be manufactured all over the world. It can be seen how difficult it is to manufacture such steel plates!

  In addition to the bottom steel plate, the aircraft carrier flight deck also needs to be sprayed with multi-layer materials with rust, salt, moisture, and sun resistance. On the one hand, it is to increase the friction coefficient and ensure the safety of the fighter aircraft during take-off, landing and transfer. On the other hand, it is also able to resist the high salt, high humidity, wind, sun, and rain in the ocean. The process of making an aircraft carrier deck is very complicated. The quality of an aircraft carrier deck directly affects its combat effectiveness.
