In what industry specific applications of titanium?

Titanium is used on ships promising. This is related to the strength of titanium, toughness relationship, there is corrosion in seawater Titanium is extremely stable, basically that the hull is not corrosive, both to reduce maintenance costs, but also can reduce the hull the weight of the ship is a great advantage in terms of ah. In addition, there is necessary to mention two things: first titanium is non-magnetic, magnetic probe against a great help, as to what the magnetic mines, ah, not worth the worry. Second, with advanced composite coating ships have a natural integration of stealth composite materials used in the future will have a disadvantage that ships with the previous use of high-strength special steel reacts readily produce electricity because of the potential difference in seawater even, accelerate corrosion, this kind of thing has been tried in the 052, will not be long rust-stained, but these coatings can be seamlessly integrated with titanium.
(2) the use of the defense industry in other countries titanium
The world has been retired, or are serving in the research of weapons and equipment, many have used the structure of titanium and its alloys, with the transformation of modern warfare mode, rapid mobility requirements of modern military capabilities are very prominent, so for the Army it must rely on the ability to achieve rapid transport mobility, which requires the Army had heavy equipment in weight as much as possible, for example, now want their countries to be able to quickly and effectively artillery quickly transferred to another place, to the strategic or tactical the purpose of this is bound to titanium in the field artillery promising a bright, like the American M777 lightweight howitzer, the use of a titanium shell, combat weight dropped to 3.175 tons, you can use the C130 V22 or air to reach rapid mobility capacity. There are similar British UFH ultralight 155 mm artillery, less than four tons of weight which uses one ton of titanium alloy. In the field of air and naval equipment is even more so, following a brief introduction to the typical examples of the successful application of titanium:
① titanium aircraft data
Today's global economy has gradually bottomed out, the international aviation industry began to resume growth, international titanium industry, along with the tide ushered in a new period of rapid growth, Chinese enterprises will usher in new opportunities.
In recent years, is starting the replacement of the fourth-generation fighter, which many years later, every year there will be many new fighters into the army. The new fighter in the selection is very particular and forward over the next many years, the military and aerospace industries must be the first major user of titanium.
Mold also recently announced a new concept submarine carrying "cormorant" unmanned attack aircraft. "Cormorant" UAV length of 5.8 meters and a wingspan of 4.86 meters, unmanned fighter aircraft belonging to repeated use. "Cormorant" by the famous Lockheed - Martin's Skunk Works design of the concept, because of its access to the channel is mainly water, so the whole machine is made of titanium alloy to prevent corrosion of the produce, the total take-off weight of not more than four tons, can carry 453 kilograms of payload, consider using methods mainly from the strategic missile launch tube Ohio-class submarine, is mainly used to destroy targets near the coast. The machine is located in the nose air intake parts, triangular in shape. As a result of titanium alloy, high strength of its body can withstand the pressure of 150 feet depth. And in order to prevent the occurrence of buckling under external pressure, internal body of unnecessary space will be filled using a special plastic intake. In order to increase flight concealment, its appearance also uses sophisticated stealth design. "Cormorant" maximum flight speed is expected to reach 880 km / h cruising speed of 550 km / h, the highest altitude 10.7 km, combat radius of up to 926 kilometers, sustainable flight three hours.
Titanium application ② Navy's
Titanium Naval above application is very extensive, the main application of power that the Soviet / Russian submarines.
"Akula" class (Akula) attack submarines: "Akula" class using the drop-type, double-shell, there is a layer of titanium alloy. Soviet famous "malachite" submarine design bureau design, Komsomolsk shipyard in Severodvinsk shipyard and manufacturing
"Sierra" class attack submarines: Russian "Sierra" (Sierra) level (also known as S-class) multi-purpose attack submarines. Can be said that the Russian nuclear submarine complex family is the most mysterious one. Mainly because the "Sierra" class boats with titanium double hull, it's big dive deep, high-speed, high firepower and good stealth performance is impressive. But the cost is very expensive, nicknamed "Goldfish", built only four. (See below)
And titanium wires in the culmination of a submarine, I still think we should grant Typhoon class: the Soviet Union built a total of six "Typhoon" class submarines, "Typhoon" was one of the first one. "Typhoon" class is unique in that: independent navigation and combat systems it a complete set of torpedoes, missiles, power devices; double shell structure, reserve buoyancy of about 32% between the two housing has more than 3 meters spacing, and enhance the ability of the explosion and crash under water. Typhoon-class vessels each with about 9000 tons of titanium, equivalent to the sum of the current year of production of titanium! Seen how huge Soviet-era military spending on the
Soviet / Russian nuclear submarine with a titanium shell as well as the Alpha level, etc., but do not have a certain climate, no longer narrative. In addition to using titanium submarines on the case, is that the use of the submarine pipes and condenser, condenser and now almost all of submarines and surface vessels are made of titanium on to do, it can be said in submarines and ships within the life, under normal circumstances do not replace the titanium condenser, one can save on maintenance costs, and second, because the problem is not the fault of the condenser to reduce attendance.
Because of material prices and production, in other countries there are few reports of the use of submarines situation titanium housing.
Performance of titanium and its alloys questioned, various metallurgical processes for titanium is also very big country conventional stuff, but consider the cost issue. With economic development, on the special requirements of national defense also has the ability to ensure that the, so that thin titanium sheet and its alloys in future civilian and military areas will usher in rapid development. While titanium and its alloys will also greatly enhance the performance of some special equipment.
