I-Titanium ineempawu ezininzi ezizodwa eziyenza ibe lolona khetho lufanelekileyo kwizicelo ezahlukeneyo kwishishini le-aerospace. Iipropathi ezinjalo ziquka umlinganiselo ophezulu wokuqina kobunzima, ukuxhathisa okugqwesileyo kwi-corrosion, kunye nokusebenza okugqwesileyo kuwo omabini amaqondo aphezulu kunye namaqondo aphantsi. Vumela umzi-mveliso wetitanium iXinyuanxiang ukwenzele uluhlu, Oku kulandelayo zezinye zeendlela ezibalulekileyo zokusetyenziswa kwe-titanium kumzi-mveliso we-aerospace:
ZISETYENZISWA KANJANI IALLOYS YE-AEROSPACE TITANIUM KWI-AIRCRAFT?
Ekubeni i-titanium ikhaphukhaphu kwaye inamandla amakhulu, ikulungele ukusetyenziswa ekuveliseni iindawo ezahlukeneyo zenqwelo-moya. Ezi ziquka iiringi ze-injini, iziqhoboshi, izikhumba zamaphiko, izixhobo zokumisa, kunye nezinye iinxalenye zesakhiwo.
Amandla aphezulu kunye nokumelana nobushushu be-titanium kuyenza ibe yinto efanelekileyo yokuveliswa kwee-blades, iirotor, kunye nezinye izinto zeenjini zenqwelomoya. Amalungu e-Titanium nawo ayakwazi ukuxhathisa ukubola okubangelwa yi-asidi yokukhupha iigesi kunye nokufuma kwe-injini.
I-Titanium sisixhobo esisetyenziswa ngokubanzi ukwenza iibholiti, izikrufu, kunye nezinye izinto zokuqhobosha kwishishini le-aerospace. Amandla aphezulu kunye nokumelana nokubola kwesi sinyithi kwenza kube lukhetho olufanelekileyo kwiifasteners eziyimfuneko kwiindawo ezinzima, ezifana neshishini le-aerospace.
Ekubeni i-titanium inomsebenzi obalaseleyo kumaqondo obushushu aphezulu, ifanelekile ukusetyenziswa kwizikhuselo zobushushu ezikhusela iindawo ezibalulekileyo zenqwelomoya. Ikhuselo lobushushu lesiphekepheke ngumzekelo ogqwesileyo, apho inceda ukunciphisa ukuhanjiswa kobushushu ukusuka enjini ukuya kwesinye isiphekepheke.
I-ADVENTS YE-AEROSPACE TITANIUM ALLOYS
Olona ncedo lubalulekileyo lwe-aerospace titanium alloys luphawu lwazo olubalaseleyo lwamandla-to-weight. I-Titanium yomelele njengeentsimbi ezininzi kodwa ine-60% kuphela yoxinaniso. Lo mhlaba uvumela ulwakhiwo lwezixhobo zenqwelomoya ezikhaphukhaphu kodwa ezomeleleyo, eziyimfuneko ekuphuculeni ukusebenza kakuhle kwamafutha kunye nokusebenza ngokubanzi.
I-aerospace titanium alloys inokumelana okugqwesileyo kokutya. Oku kuxhathisa kwizinto ezisingqongileyo, ezifana nokufuma kunye netyuwa emoyeni, kuqinisekisa ixesha elide kunye nokuthembeka kwamacandelo eenqwelomoya. Izinto ezikwaziyo ukumelana nomhlwa zibaluleke kakhulu kwinqwelo-moya, edla ngokuchanabeka kwiimeko ezahlukeneyo zemozulu.
Iialloyi ze-Titanium zigcina iimpawu zazo zomatshini kumaqondo obushushu aphezulu, nto leyo iyimfuneko kumalungu asebenza kubushushu obugqithisileyo obuveliswa ziinjini zenqwelo-moya. Ukukwazi ukumelana nobushushu obuphezulu ngaphandle kokuthotywa okubalulekileyo kuqinisekisa ukhuseleko kunye nokusebenza kwezi ndawo zibalulekileyo.
Ii-alloys ze-Titanium ziyaziwa ngokuchasana nokudinwa, oko kukuthi ubuthathaka bezinto eziphantsi komthwalo we-cyclic. Le propati ibalulekile kumacandelo afana nezixhobo zokumisa ezifumana uxinzelelo oluphinda-phindayo ngexesha lokubhabha. Ukumelana nokudinwa kwe-titanium kunegalelo kukhuseleko lulonke kunye nobomi benqwelomoya.
Nangona ingahambelani ngokuthe ngqo kwinqwelomoya, i-biocompatibility ye-titanium ifanele ukukhankanywa. Yinto engeyiyo ityhefu kunye ne-biologically inert material, eyenza ilungele ukufakelwa kwezonyango. Amacandelo amaninzi eenqwelo-moya aveliswa ngenxa yophando nophuhliso lweshishini le-aerospace, exhamla kwi-biocompatibility ye-titanium.
Kwishishini le-aerospace, amabakala amaninzi e-titanium asetyenziswa ngokuxhomekeke kwiimfuno ezithile zecandelo okanye isakhiwo seemveliso ze-titanium zesiko. Amanqaku amabini asetyenziswa kakhulu ngala:
I-titanium yeBanga lesi-5, ekwabizwa ngokuba yi-Ti-6Al-4V, yeyona alloy isetyenziswa kakhulu kwinqwelomoya. Iqulathe 90% titanium, 6% aluminiyam, kunye 4% vanadium. Le ngxubevange inika indibaniselwano egqwesileyo yamandla aphezulu, ukuxhathisa umhlwa, kunye nokumelana nobushushu. Ipleyiti yetitanium ye-GR5 idla ngokusetyenziswa kulwakhiwo lwenqwelomoya, iinxalenye zenjini, kunye neziqhoboshi ngenxa yeempawu zayo ezimangalisayo.
I-titanium yeBakala 2, okanye i-Ti-CP (i-Commercially Pure), luhlobo olusulungekileyo lwe-titanium enomxholo omncinci wezinto ezixutywayo. Ithathelwa ingqalelo kakhulu ngenxa yokuxhathisa kwayo okugqwesileyo, iyenza ibe lolona khetho lufanelekileyo kumalungu avezwe kwindawo enobundlobongela. I-titanium yeBanga lesi-2, efana nepleyiti yetitanium ye-GR2 isoloko isetyenziswa kwinqwelo-moya apho ukudleka kuyinkxalabo ebalulekileyo, njengeziqhoboshi, izixhobo zokumisa, kunye neenkqubo zokukhupha umoya.
