Because Nitinol alloy shape memory alloy has unique nitinol alloy shape memory alloy functions, it also has the advantages of superelasticity, abrasion resistance and corrosion resistance, so it has been widely used in many fields.
The use of nitinol alloy shape memory alloys in the machinery industry was originally used in pipe joints and fasteners. Specifically, in the connection of mechanical parts, pipelines, etc., at the interface of aircraft for aerial refueling, nitinol alloy shape memory alloy is used to process a casing with an outer diameter 3% larger than the inner diameter, and at a certain temperature, the diameter expansion of the casing is about 8%. In assembly, the casing is removed from the liquid nitrogen and the tube is inserted from both ends. If the temperature rises to room temperature, electric heating can be used to change the temperature. The shape memory alloy of nitinol alloy at the air refueling interface is deformed, and the shape memory alloy of nitinol alloy is processed. The casing shrinks to form a tight seal, so as to achieve tightness without oil leakage, and the effect is much higher than traditional welding. Therefore, nitinol alloy shape memory alloys are particularly suitable for aerospace, ships, oil pipelines and other fields. In locations where construction is inconvenient, nitinol alloy shape memory alloy can be used to make pins and put them into the holes for heating. Therefore, the temperature sensing and multiple functions of nitinol alloy shape memory alloys are used to make robots, manipulators, etc.
The various characteristics of nitinol alloy shape memory alloys mentioned earlier, combined with the structure of nitinol alloy shape memory alloys, can enhance the damping of the system and reduce the dynamic response of the structure, thereby producing various forms of damping energy-consuming devices. You can also use nitinol alloy shape memory alloy to design vibration isolators, increase deformation displacement energy consumption through the deformation of nitinol alloy shape memory alloy, and prevent the transmission of structural seismic energy to the upper structure, thereby protecting the upper structure and truly enhancing the seismic performance of the structure.
In the hydraulic system of an aircraft, basically every aircraft needs to use 800 nitinol alloy shape memory alloy joints. Since the 1970s, most U.S. naval aircraft have used this type of pipe joint, and there is no record of failure. In addition, nitinol alloy shape memory alloys can also be used in spacecraft antennas, electromechanical execution components, etc.
Nitinol alloy shape memory alloy is mainly used in engine exhaust fan clutches, exhaust nozzles, diesel engine radiators, etc.
Nitinol alloy shape memory alloy has high mechanical properties and biological compatibility, which has made it widely used in the medical field. Such as orthodontics, plastic surgery, cardiovascular minimally invasive, etc.; thrombosis filters are actually new products of nitinol alloy shape memory alloys; straightened filters will gradually form a mesh over time after being implanted in the veins, preventing more than 90% of blood clots from flowing to the heart, lungs and other organs. In addition, nitinol alloy shape memory alloys are used in medical clinical trials, including surgical sutures, artificial joints, and artificial hearts.
