Impumelelo enkulu yeshishini le-aerospace ayinakwahlulwa kuphuhliso kunye nokuphumelela kwitekhnoloji yemathiriyeli ye-aerospace. Ukuphakama okuphezulu, isantya esiphezulu kunye nokuhamba okuphezulu kweejethi zokulwa kufuna ukuba izinto zesakhiwo senqwelomoya kufuneka ziqinisekise ukomelela okwaneleyo kunye neemfuno zokuqina. Izinto ze-injini kufuneka zihlangabezane nemfuno yokumelana nobushushu obuphezulu, i-alloys yobushushu obuphezulu, izinto ezihlanganisiweyo ezisekwe kwi-ceramic zezona zinto ziphambili.

Intsimbi eqhelekileyo ithambisa ngaphezulu kwe-300 ℃, iyenza ingafaneleki kwiindawo ezinobushushu obuphezulu. Kwiphulo lokuguqula amandla aphezulu, amaqondo obushushu aphezulu naphezulu okusebenza ayafuneka kwindawo yamandla enjini yobushushu. Iialloys zobushushu obuphezulu ziye zaphuhliswa ukuze zisebenze ngokuzinzileyo kumaqondo obushushu angaphezu kwe-600℃, kwaye iteknoloji iyaqhubeka nokuvela.

I-alloys yobushushu obuphezulu zizinto eziphambili kwiinjini ze-aerospace, ezahlulwe kwi-iron-based high-temperature alloys, i-nickel-esekelwe kwizinto eziphambili ze-alloy. Ii-alloys zobushushu obuphezulu zisetyenzisiwe kwii-injini ze-aero-injini ukususela ekuqaleni kwazo, kwaye zizixhobo ezibalulekileyo ekwenziweni kweenjini ze-aerospace. Umgangatho wokusebenza we-injini uxhomekeke kakhulu kwinqanaba lentsebenzo yezixhobo zokushisa eziphezulu ze-alloy. Kwii-injini ze-aero-i-injini zanamhlanje, inani lezinto eziphezulu zokushisa kwe-alloy zenza i-40-60 yepesenti yobunzima be-injini, kwaye isetyenziselwa ubukhulu becala amacandelo amane aphambili ashushu: amagumbi okutshisa, izikhokelo, ii-turbine blades kunye nee-disc ze-turbine, kwaye ukongezelela, isetyenziselwa amacandelo afana ne-nozzles, ii-nozzles kunye ne-combus.

I-nickel-based alloys yobushushu obuphezulu isebenza ngokubanzi kuma-600 ℃ ngaphezu kweemeko zoxinzelelo oluthile, ayinayo kuphela i-oxidation ephezulu yobushushu obuphezulu kunye nokumelana nomhlwa, kwaye inamandla obushushu obuphezulu, amandla okurhubuluza kunye namandla okunyamezela, kunye nokuxhathisa okulungileyo kokudinwa. Isetyenziswa kakhulu kwintsimi ye-aerospace kunye ne-aviation phantsi kweemeko zobushushu obuphezulu, amacandelo esakhiwo, njengama-injini e-aircraft blades, iidiski ze-turbine, amagumbi okutsha kunye nokunye. I-alloys ye-nickel-based high-temperature alloys inokwahlulwa ibe yi-alloys ephosakeleyo yobushushu obuphezulu, i-alloys yokushisa okuphezulu kunye ne-alloys entsha yokushisa okuphezulu ngokwenkqubo yokuvelisa.

Kunye nobushushu-resistant ingxubevange ubushushu ukusebenza iphezulu nangaphezulu, izinto ukomeleza kwi ingxubevange ngakumbi nangakumbi, kokukhona ukwakheka entsonkothileyo, okubangela ezinye ingxubevange ingasetyenziswa kuphela kwimo ephosiweyo, ayikwazi deformed processing eshushu. Ngaphezu koko, ukwanda kwezinto ezixutywayo kwenza i-alloys esekelwe kwi-nickel iqine ngokuhlukana okunzulu kwamacandelo, okubangelwa ukungafani kombutho kunye neepropati.Ukusetyenziswa kwenkqubo ye-metallurgy yomgubo ukuvelisa i-alloys yobushushu obuphezulu, kunokusombulula ezi ngxaki zingasentla.Ngenxa yeengqungquthela ezincinci zepowder, isantya sokupholisa umgubo, ukuphelisa ulwahlulo, ukuphuculwa kokusebenza okushushu, i-alloy yokuphosa yasekuqaleni kwi-deformation eshushu esebenzayo ye-alloys yobushushu obuphezulu, amandla esivuno kunye neempawu zokudinwa ziphuculwe, i-powder high-temperature alloy yokuvelisa i-alloys yamandla aphezulu ivelise indlela entsha.
