medical titanium bar Such a process can greatly increase the strength

After an anti- aircraft J20 appear different from the past , the whole body almost see the rivets, some people said it was because the stealth coating covers the outside , so you do not see the rivets , in fact, this is wrong. F22 is using rivets , close look carefully medical titanium bar you can see it. Why not F22 rivets completely covered with a coating to see it? This is because the skin is F22 by a piece of riveting rivets up, rivets can not cover for easy maintenance , in case you can quickly remove the rivets skin pulls off a piece , and can determine with the naked eye whether the fuselage skin cracks.
    So J20 Why not see rivets it? In fact, this and related processing technology , due to the advances in technology, a large piece of titanium alloy ingots J20 using whole body casting , extrusion and then press through a dedicated , increased density , ( the two years prior to the successful development of the machine , once media have reported that this is the aircraft fuselage presses developed specifically for J20 ) , and finally the use of CNC machine tools hollowed out , which is a ** , high-precision CNC machine tools , the entire titanium aluminum alloy castings ( diameter may up to 3 meters ) hollowed out into the shape of the aircraft fuselage , so the aircraft do not need to cover the skin, the skin of the fuselage frame and a titanium alloy ingots are then processed , so do not see J20 rivets.

    After processing J20 in the fuselage just put on the surface of the fuselage stealth patch, we note the following diagram , J20 stealth patch is pasted a block , a bit like a submarine acoustic rubber blocks. If you later off a piece of stealth patch just paste a new on OK, so the aircraft maintenance is very easy .
    J20 of the integral processing technology is currently the world's first application in aircraft , F35 will still rely on the rivet , not to mention the Russian T50 , 20 years ago, the process is completely , there is no fundamental and J20 comparable. So an advanced aircraft can not just look at the surface , J20 to strategic needs medical titanium bar ( to carry large amounts of fuel to increase range and large anti-ship missiles ) and designed long body, such a body if the old conventional processing technology we rely the naked eye does not feel his body proportions , the body is too long , the body is weak at the middle of stress , where the most easily broken, but after the introduction of new technology completely eliminates this drawback . So just come out when J20 foreign aircraft design experts feel incomprehensible , but once the solution to doubt its processing will become clear.

medical titanium bar Titanium tube welded using inert gas welding area

Titanium tube welders law process characteristics
Titanium tube welded using inert gas welding area for the effective protection of TiG welding process. Since titanium has special physical and chemical properties , and thus there is a big titanium alloy wire  difference in the welding process and other metals.
Titanium pipe welding must ensure :
Pollution ( a ) weld metal zone is not more than 250 ℃ reactive gas N, 0, H and harmful impurity elements C, Fe, Mn and the like.
( 2 ) can not form a coarse grain structure .
( 3 ) does not produce a large welding residual stress and deformation. Therefore, the welding process is required to reserve the construction sequence , in strict accordance with process quality management standards , the implementation of quality control of the whole process. People , machine , material, method factors are controlled in a good state to work in a reasonable period, to ensure the quality of welding titanium tube.
Titanium pipe welding using materials, equipment and tools
4.1 titanium pipes and fittings : shall have the manufacturer's factory certification and quality certificates . After retesting its size, chemical composition , mechanical properties and availability status should comply with DIN17850 standards.
Titanium pipe welding material
Wire ; wire grades ERTi-2, titanium welding wire select the wire should meet the following requirements:
(L) the chemical composition and mechanical properties of the wire should be fairly and base metal ;
( 2 ) If the welded parts require high plasticity , should adopt a purity higher than the base metal wire.
Wire retest before using the material , the factory inspection certificate and certificate of quality to be ; wire surface should be clean and free of oxidation color , no cracks , peeling, spot scars and defects such as slag . The chemical composition of the wire should comply with the relevant provisions of AWSA5.16-70 's .

medical grade titanium use it at a certain temperature changes shape


Since memory alloy is a " life has alloy " , use it at a certain temperature changes shape , you can design all kinds of self-control devices , its use is expanding . The first application of shape memory alloy pipe fittings in and fasteners . A shape memory alloy is processed into an outer diameter smaller than the internal diameter of the pipe medical grade titanium to be connected to the casing 4% , at liquid nitrogen temperature and then expanding the sleeve diameter of about 8% , this will be removed from the cannula assembly when the liquid nitrogen , the desire inserted from both ends of the tube connection . When the temperature was raised to room temperature , i.e., the sleeve forming a holding seal shrinkage . This connection can be in close contact with anti-leakage , far better than welding , especially suitable for aviation, aerospace , nuclear industry and submarine pipelines and other dangerous situations. The most promising application memory alloys in aerospace technology . July 20, 1969 , "Apollo" 11 lunar module landed on the moon , the first human landing on the moon to achieve the dream of traveling . After the astronauts landing on the moon , on the moon a few meters in diameter placed a large hemispherical antenna for transmitting and receiving information to Earth . A few meters from a large antenna mounted on the tiny lunar module sent into space inside . Antenna that was just invented near memory alloy used. Under normal circumstances, the first predetermined requirements of good memory alloy material with a very thin , then lower the temperature to press thin titanium sheet it into a ball , bring the day to go into the lunar module . Into the lunar surface after the temperature rise in the sunlight , when it reaches the transition temperature , antennas and " mind" from their original appearance , becomes a huge domed . At present, the shape memory effect and superelasticity has been widely used in various fields of medicine and life . Thrombus filter manufacturing , spinal orthopedic rods, plates , artificial joints, women bra , artificial heart and so on. Can also be widely used in a variety of automatic regulation and control devices. Shape memory films and filaments may be the ideal material for future ultra- miniature robots and robots. Especially its light weight, high strength and corrosion resistance makes it highly titanium sheet metal popular in various fields .
