Izimiso Zokusebenza kanye Nezimpawu Zokusebenza Ze-Titanium Alloys

Ama-alloys e-Titanium ayi-titanium{0}ama-alloys asekelwe nezinye izakhi zensimbi (njenge-aluminium, i-vanadium, i-chromium, ne-molybdenum). Ngenxa yezakhiwo zabo ezinhle kakhulu zemishini kanye nokumelana nokugqwala, zisetshenziswa kabanzi ku-aerospace, biomedical, engineering yasolwandle, nakweminye imikhakha. Isimiso sabo sokusebenza sisekelwe ngokuyinhloko ezintweni ezibonakalayo namakhemikhali e-titanium kanye nezindlela zokuqinisa ezenzeka ngemva kokuhlanganiswa.

Isakhiwo se-athomu ye-Titanium siyinikeza amandla athile aphezulu kanye nokuminyana okuphansi. Ukuminyana kwayo kungamaphesenti angama-60 kuphela okwensimbi, kodwa amandla ayo asondela noma adlule ngisho nawamanye ama-alloy steels. Ama-alloys e-Titanium aqiniswa ngokuyinhloko ngokuqiniswa kwesisombululo esiqinile, ukuqiniswa kwemvula, nokuqina komsebenzi. Isibonelo, i-aluminium ne-vanadium yizici ezivamile ze-alloying. I-Aluminium ithuthukisa amandla e-titanium ngenkathi igcina ukuqina okuhle, kuyilapho i-vanadium ithuthukisa ubulukhuni bayo nokumelana nokugqoka ngokwenza izinhlanganisela ezinhle ze-intermetallic (njenge-TiAl₃). Ngaphezu kwalokho, ama-alloys e-titanium agcina izakhiwo ezinzile zemishini ngisho emazingeni okushisa aphezulu, ngenxa yezinga lawo eliphakeme lokuncibilika (cishe ama-degree angu-1668) kanye nokumelana okuhle kakhulu nokukhasa.

Ukumelana nokugqwala kwama-alloys e-titanium kubangelwa ifilimu eliminyene le-oxide (TiO₂) elakheka phezulu. Le filimu ivimbela ngempumelelo i-oxidation eyengeziwe kanye nokugqwala, ihlale izinzile ngisho nasemanzini olwandle nasezindaweni ezine-asidi noma ezine-alkaline. Emkhakheni wezinto eziphilayo, i-biocompatibility ye-titanium alloys ibenza ibe yinto ekahle yamalunga okwenziwa kanye nokufakelwa kwamazinyo, njengoba engabangeli ukulahlwa futhi yakhe isibopho esiqinile ngezicubu zethambo.

Ngamafuphi, isimiso sokusebenza se-titanium alloys sincike ezicini zemvelo ze-titanium kanye nokukhohlisa kwe-microstructural ngemva kokuhlanganiswa kwengxubevange, kufinyelelwe ibhalansi phakathi kwamandla, ukumelana nokugqwala, kanye ne-biocompatibility ukuze kuhlangatshezwane nezidingo eziqinile zemikhakha{0}}yezimboni nezokwelapha.
