Uyini umehluko phakathi kwensimbi ye-titanium, i-titanium ehlanzekile, ne-titanium alloys?
insimbi yesigqoko se-titanium ayinayo i-titanium, futhi ingxenye yayo eyinhloko iseyinsimbi. Leli gama lezohwebo ukulihlukanisa kwezinye izinsimbi ezingenasici lapho lisetshenziswa njengobucwebe futhi lithola inani eliphakeme. izindleko nokumelana nokugqwala kwe-316L yensimbi engagqwali ngempela kungcono kunensimbi evamile engagqwali.
Yini engabizwa izinto ze-titanium ngokuvamile iwela ezigabeni ezimbili, eyodwa i-titanium emsulwa, kanti enye i-titanium alloy.
Lena ene-titanium ephezulu kakhulu isipontshi se-titanium esisanda kwakhiwa, esenziwe nge-titanium tetrachloride encishiswe yi-magnesium. Kubukeka kanjena:
Ikhululekile futhi inezimbotshana ezinamandla aphansi kakhulu futhi ayikwazi ukusetshenziswa ngokuqondile njengempahla ye-titanium. Yimpahla ekhuphuka kakhulu ye-titanium. Icutshungulwa ibe yizimo ezihlukahlukene zamapuleti, izintambo, amashubhu, njll. ngemva kokuncibilika, ukubumba, nokugingqika.
Okuqukethwe kwe-titanium kwesipontshi se-titanium kusondele ku-100%. Kodwa-ke, i-titanium iyasebenza kakhulu futhi ingasabela kalula nge-oxygen, i-nitrogen, i-hydrogen, njll. emoyeni lapho ibekwe emoyeni, ngakho-ke cishe akunakwenzeka ukufeza ubumsulwa obungu-100%.
Ngokuvamile, uma okuqukethwe kwe-titanium kungaphezulu kuka-95%, kunjalo i-titanium ehlanzekile yezimboni. I-titanium ehlanzekile ihlukaniswe nge-TA1-TA4 ngokuya ngokuqukethwe kwe-titanium nokungcola. Okuvame kakhulu esivame ukukusebenzisa yi-TA1 ne-TA2. Ukungcola ikakhulukazi umoya-mpilo, i-nitrogen, i-hydrogen, i-carbon, i-iron, njll. Uma iphezulu okuqukethwe kwe-titanium, ithambile, futhi iyancipha amandla ayo, kodwa ngcono ukuqina kwayo.
Ngakho-ke, lapho senza amabhande ebhande le-titanium nobucwebe be-titanium, sizosebenzisa izinto ze-TA1 ezindaweni lapho amandla angenamandla kakhulu, kuyilapho ama-shafts nezikulufu ezincane zizosebenzisa izinto ze-TA2.
Uma senza izinkomishi ezihlanzekile ze-titanium, asikwazi ukusebenzisa i-TA2. Ukuphakama kokuhlanzeka, kungcono. Ikakhulukazi, okuqukethwe kwe-hydrogen kufanele kube phansi, ngaphandle kwalokho, kuzoqhekeka kalula ngenxa yokuqina okwanele, noma kuzoba nemigqa elula ecacile. Noma iphikisiwe, izinga le-scrap lizoba phezulu kakhulu.
Okulandelayo, ingxubevange ye-titanium, njengoba negama libonisa, ingxubevange eyakhiwe nge-titanium nezinye izinsimbi nezingezona izinsimbi. Lezi zinsimbi nezingezona zensimbi ezifana ne-aluminium, i-molybdenum, i-vanadium, i-chromium, i-iron, i-zirconium, ithini, umoya-mpilo, ikhabhoni, njll. Ama-alloys e-Titanium ahlukaniswe abe yi-TA, TB, kanye nochungechunge lwe-TC ngokwezakhiwo ezihlukene ze-metallographic. Ngeke ngingene emininingwaneni lapha.
Thatha i-TC4 titanium alloy esetshenziswa kakhulu njengesibonelo. Okuqukethwe kwayo kwe-titanium kungu-90%, i-aluminium 6%, ne-vanadium 4%, ngakho-ke ibizwa nangokuthi i-titanium 6 aluminium 4 vanadium. I-TC4 titanium alloy ingxubevange ye-titanium eyathuthukiswa yokuqala futhi esetshenziswa kakhulu emhlabeni. Futhi ingxubevange yokuqala ye-titanium esetshenziswa ekwelashweni. Okukhiphayo kubala ngaphezu kwengxenye yomkhiqizo ophelele wemikhiqizo ehlukahlukene ye-titanium alloy emhlabeni, ikakhulukazi embonini ye-aerospace. Ngaphezu kwama-80%. Inezindawo eziphakeme zokunqanda ukugqwala, inamandla kune-titanium emsulwa, inokuqina okuhle, futhi kulula ukuyicubungula nokushisela, ngakho ukusebenza kwayo kukonke kuhle kakhulu, futhi ayikubangeli ukungezwani komzimba njenge-titanium emsulwa.
yikuphi okungcono, i-titanium ehlanzekile noma i-titanium alloy?
Lokhu akuphelele. Izinto ezihlukene zifanele imikhiqizo ehlukene. Ngokuvamile, ngaphandle kwezici ezifana nokubukeka, izindleko ezibonakalayo ze ingxubevange ye-titanium iphakeme kunaleyo ye-titanium emsulwa. Yiqiniso, ingxubevange ye-titanium lapha kufanele ibe yezinga elivamile, elisekelwe ku-titanium futhi lingezwe nezinye izinsimbi nezingezona zensimbi, kunokuba ungeze i-titanium encane kwezinye izinsimbi futhi uzenze i-titanium alloy uma iqukethe kancane. titanium.
