In life, a small screw is commonplace, and some are even children's toys, but it is this small screw that plays a huge role in all walks of life in human life. Its birth has made a qualitative leap in the development of human industry, and people call screws and their kind "fasteners" in the industrial field. Fasteners are known as "industrial rice", and Academician Wu Guanghui, chief Oblikovalec velikega potniškega letala C919, ki so hvalili pritrdilne elemente kot "več deset tisoč, podobno kot skupina, celo strukture, povezane sisteme in majhne stvari so velike" . in zaradi različnih polj za uporabo ljudje uporabljajo različne kovinske materiale za izdelavo pritrdilnih elementov .
The advantages of titanium alloy fasteners are small density, high strength and high specific strength: compared with steel materials, titanium alloy has a small density and is lightweight. The extensive use of titanium alloy fasteners can significantly reduce the mechanical quality and reduce energy consumption, which is not only an environmental issue, but also an obvious economic account. The strength and specific strength of titanium alloy so boljši od aluminijeve zlitine in očitno je bolj primerna za nekatera ekstremna okolja, kot sta prostor in ocean .
Strong corrosion resistance: titanium is not corroded in some corrosive media, such as seawater, wet chlorine, chlorite and hypochlorite solutions, nitric acid, chromic acid, metal chloride, sulfide and organic acids. Titanium alloy fasteners are widely used in marine engineering, chemical refining and other fields. Good heat resistance: usually aluminum at 150℃, stainless steel at 310℃that loses its original properties, while titanium alloy still maintains good mechanical properties at about 500℃. When the speed of the aircraft reaches 2.7 times the speed of sound, the surface temperature of the aircraft structure reaches 230℃, aluminum alloy and magnesium alloy can no longer be used, and Titanova zlitina lahko izpolnjuje zahteve . Non-Magnet: Titanium je popolnoma nemagnetna kovina, zato so pritrdilni elementi iz titanove zlitine primernejši za uporabo v različnih natančnih strojih, da se izognejo dodatnim magnetnim učinkom na te stroje, ki so zelo pomembni v Aerospace Industry.
Small coefficient of thermal expansion and modulus of elasticity: The coefficient of thermal expansion and modulus of elasticity of titanium alloy materials are smaller than those of nickel alloys and steel materials, and the thermal stress generated by titanium alloys is very small in the same temperature change range, so titanium alloys have high thermal fatigue properties. High appearance: The surface of titanium can show a variety of colors, so it is also called "colored titanium". This "coloring" skill is a unique property of titanium, and titanium fasteners are no exception, and many people like to use colorful titanium fasteners to highlight their unique characteristics. Application of titanium alloy fastenersTitanium alloy fasteners have very good comprehensive properties and are Primerno za uporabo v številnih panogah: Aerospace: Uporaba pritrdilnih elementov iz titanijeve zlitine, ki je najprej nastala v vesoljskem polju ., ki sega v 50 -ih let prejšnjega stoletja, so ZDA prevzele vodstvo pri uporabi titanijevih zlitin tesnih vijakov na B. bombnih rezultatov in dosegale prometne rezultate in doseglo obratno teže in doseglo obratno teže in doseglo obratno rezultate rezultatov.
The history of titanium alloy fasteners in China began in 1965, and in the 80s of the 20th century, a small number of titanium alloy fasteners such as rivets and bolts began to be used in some second-generation military aircraft in China. In recent years, China's research and development of titanium alloy materials and fastener manufacturing technology has been progressing, and titanium alloy fasteners have been Široko uporabljene na vesoljskem področju in so tudi zelo cenjeni pri civilnih zrakoplovih . na morju inženiring: v morskem okolju se pritrdilni pritrdilniki iz titanijevih zlitin lahko učinkovito upirajo eroziji morske vode, izboljšajo življenjsko dobo strojev in olajšajo vzdrževanje, ki ni primerna za predmeti titanijeve narave titanijeve narave, ki ne bi mognectično naravo titanijeve narave, ki ne magnetsko naravo titanijeve narave, ki niso primerne, da se ne-magnetična narava titanijeve narave titanijevo naravo titanijevo hitrih zlitin ne more, da se ne magnectična narava titanijeve narave titanijevo naravo titanijeva hitrostjo, kar ni primerno, da se ne-magnetična narava titanijeve narave titanijevo naravo ne more, da bi se ti titanska narava titanium zlitine, ki ni primerna, ne-magnetična narava titanijeve. Eksplozija rudnikov . kemična industrija: Kemična industrija je bila vedno prvo večje področje titana na Kitajskem, vloge pritrdilnih elementov iz titanijevih zlitin v tej panogi Pritrdilni pritrdilniki iz titanijevih zlitin igrajo pomembno vlogo pri vesoljskem, morskem inženiringu, kemični industriji in civilnih področjih z njihovimi odličnimi obsežnimi lastnostmi ., čeprav je cena zlitine iz titana razmeroma visoka, z napredkom proizvodnje materiala iz titana, uporaba pritrditve titanijeve zlitine na civiliskem polja se bo bolje promotila. 13}
