ubushushu obuphezulu be-titanium crucible yokunyibilika eziko
Iqondo lokunyibilika kwetitanium limalunga ne-1,668 degrees Celsius (3,034 degrees Fahrenheit). Eli nqanaba eliphezulu lokunyibilika lenza i-titanium ifaneleke kwizicelo eziphezulu zokushisa, kubandakanywa ukwenza ii-crucibles zokunyibilika kwiziko kunye nezinye iinkqubo ezibandakanya ukubonakaliswa kokushisa okukhulu.
Kwiqondo lokushisa eliphezulu, i-titanium ifumana utshintsho oluhlukeneyo kunye nokuphendula. Ezinye izinto eziphambili zokuziphatha kwe-titanium kumaqondo obushushu aphezulu ziquka:
1. I-Oxidation: I-Titanium inokusabela ngeoksijini kumaqondo obushushu aphezulu ukwenza umaleko omncinci we-titanium dioxide (TiO2) kumphezulu wayo. Lo maleko we-oxide ubonelela ngesinyithi ngokuxhathisa okugqwesileyo kwe-corrosion, ukuyikhusela ekuqhubekeni kwe-oxidation kunye nokuthotywa.
2. Ukugcinwa kwamandla: I-Titanium igcina amandla kunye nengqibelelo yayo kumaqondo okushisa aphezulu, evumela ukuba igcine uzinzo lwesakhiwo kwiindawo ezinzima. Lo mhlaba wenza i-titanium ibe yimathiriyeli exabisekileyo kwi-aerospace, ukusetyenzwa kwamashishini kunye nezicelo zobunjineli zobushushu obuphezulu.
3. Utshintsho lwesigaba: Kwiqondo lokushisa elithile eliphakamileyo, i-titanium inokutshintsha isigaba, iguqule isakhiwo sayo se-crystal kunye neempawu. Olu tshintsho lunokusetyenziswa ukulungelelanisa iimpawu zemathiriyeli kwizicelo ezithile.
4. I-reactivity: Nangona i-titanium ikwazi ukumelana nokuhlwa, inokusabela ngeegesi ezithile kunye nezinto ezithile kumaqondo obushushu aphezulu kakhulu, okukhokelela ekwenziweni kweekhompawundi ze-titanium kunye ne-alloys.
Ngokubanzi, ukuziphatha kwe-titanium kumaqondo aphezulu okushisa kubonakala ngokukwazi ukugcina amandla, ukuxhathisa i-oxidation, kunye nokutshintshwa kwesigaba esilawulwayo, okwenza kube yinto eguquguqukayo kunye nethembekileyo ukuze isetyenziswe kwiimeko eziphezulu zokushisa.
