Li-alloys tsa Titanium li na le thepa e ntle haholo ea mochini empa lisebelisoa tse mpe tsa ts'ebetso, e leng se lebisang khang ea hore litebello tsa ts'ebeliso ea tsona lia ts'episa empa ts'ebetso e thata.Ka pampiri ena, ka ho sekaseka ts'ebetso ea tšepe ea tšepe ea lisebelisoa tsa alloy ea titanium, e kopantsoe le lilemo tse ngata tsa boiphihlelo bo sebetsang ba mosebetsi, khetho ea lisebelisoa tsa ho itšeha tsa titanium alloy, boikemisetso ba ho itšeha lebelo, litšobotsi tsa mekhoa e fapaneng ea ho itšeha, meputso ea machining le mehato ea ts'ireletso. lia buisanoa.E hlalosa maikutlo a ka le litlhahiso mabapi le ho etsoa ha li-alloys tsa titanium.
Titanium alloy e na le letsoalo le tlase, matla a khethehileng (matla / boima), ho hanyetsa kutu e ntle, ho hanyetsa mocheso o phahameng, ho tiea hantle, polasetiki le ho cheseha.Li-alloys tsa Titanium li 'nile tsa sebelisoa haholo libakeng tse ngata.Leha ho le joalo, ho se sebetse hantle ha mocheso, ho thatafala ho phahameng, le modulus e tlase ea elastic le tsona li etsa hore li-alloys tsa titanium e be lisebelisoa tse thata ho sebetsa.Sengoliloeng sena se akaretsa mehato e meng ea mahlale ho machining ea li-alloys tsa titanium ho ipapisitse le litšobotsi tsa eona tsa mahlale.
Melemo e ka sehloohong ea lisebelisoa tsa alloy titanium
(1) Titanium alloy e na le matla a phahameng, boima bo tlaase (4.4kg / dm3) le boima bo bobebe, bo fanang ka tharollo ea ho fokotsa boima ba likarolo tse ling tse kholo tsa mohaho.
(2) Matla a phahameng a mocheso.Li-alloys tsa Titanium li ka boloka matla a phahameng tlas'a boemo ba 400-500 ℃ 'me li ka sebetsa ka mokhoa o tsitsitseng, ha mocheso o sebetsang oa li-alloys tsa aluminium o ka ba ka tlase ho 200 ℃.
(3) Ha ho bapisoa le tšepe, khanyetso e phahameng ea kutu ea titanium alloy e ka boloka litšenyehelo tsa ts'ebetso ea letsatsi le letsatsi le tlhokomelo ea sefofane.
Tlhahlobo ea litšobotsi tsa mochini oa titanium alloy
(1) Low mogote conductivity.Thermal conductivity ea TC4 ho 200 ° C ke l = 16.8W / m, 'me conductivity ea mocheso ke 0.036 cal / cm, e leng 1/4 feela ea tšepe, 1/13 ea aluminium le 1/25 ea koporo.Ts'ebetsong ea ho itšeha, mocheso oa mocheso le phello ea pholileng ha o na thuso, o khutsufatsang bophelo ba sesebelisoa.
(2) The elastic modulus e tlase, 'me bokaholimo ba karolo e entsoeng ka mochini bo na le sekhahla se seholo, se lebisang keketsehong ea sebaka sa ho ikopanya lipakeng tsa bokaholimo ba mochini le bokaholimo ba sesebelisoa, se sa amang feela ho nepahala ha dimensional. karolo, empa hape e fokotsa ho tšoarella ha sesebelisoa.
(3) Ts'ebetso ea polokeho nakong ea ho itšeha ha e ntle.Titanium ke tšepe e tukang, 'me mocheso o phahameng le litlhase tse hlahisoang nakong ea ho seha ha nyane li ka etsa hore litsupa tsa titanium li che.
(4) Ntho e thata.Li-alloys tsa Titanium tse nang le boleng bo tlaase ba boima bo tla khomarela ha ho etsoa machining, 'me li-chips li tla khomarela moeling oa sefahleho sa rake sa sesebelisoa ho theha moeli o hahiloeng, o amang phello ea machining;li-alloys tsa titanium tse nang le boleng bo phahameng ba ho thatafala li na le tšekamelo ea ho phunya le ho senya sesebelisoa nakong ea machining.Litšobotsi tsena li lebisa tekanyong e tlaase ea ho tlosoa ha tšepe ea titanium alloy, e leng 1/4 feela ea tšepe, 'me nako ea ho sebetsa e telele ho feta ea tšepe ea boholo bo lekanang.
(5) Kamano e matla ea lik'hemik'hale.Titanium ha e khone ho itšoara ka lik'hemik'hale feela ka likarolo tse ka sehloohong tsa naetrojene, oksijene, carbon monoxide le lintho tse ling tse moeeng ho etsa lera le thata la TiC le TiN holim'a motsoako, empa hape le sebetsana le lisebelisoa tsa lisebelisoa tlas'a mocheso o phahameng. maemo a hlahisoang ke mokhoa oa ho itšeha, ho fokotsa sesebelisoa sa ho itšeha.ea ho tšoarella.
