Ngokuphuhliswa okuqhubekayo kwemveliso kunye netekhnoloji, izixhobo ezininzi ezisetyenziswa kwiindawo zobushushu eziphezulu zijamelene nemiceli mngeni enzima. Phantsi kweemeko ezinjalo, iingubo ezinyaweni ezinganyangekiyo ziyiteknoloji enobuchule enokubonelela ngokhuseleko olusebenzayo lwemisebenzi eyahlukeneyo kunye nokuqinisekisa ukuzinza kwazo kunye nokuqina kwiindawo zobushushu obuphakamileyo.
Ukuhlekiswa kobushushu obunganyangekiyo kukuhlela okwenzayo okukhethekileyo kunye nokunganyangeki kobushushu obuphezulu. Inokumelana nobushushu obugqithisileyo ukusuka kumakhulu ambalwa amakhulu eCelsius kumawaka ama degrees Celsius kwaye agcine iipropathi zayo zokwenyama kwaye azinze ixesha elide. Oku kwenza ukuba iingubo zobushushu obunganyangekiyo kubushushu obukhetho lokuqala kumashishini amaninzi, ngakumbi kwi-aerospace, i-petrochemicals, ukuvelisa izithuthi kunye namandla.
Enye yezakhiwo eziphambili zengubo yobushushu obunganyangekiyo yingqungquthela yazo ebalaseleyo. Ingafumana ngokuphumelela kwaye iqhuba ubushushu kumphezulu wento eceliweyo, igcina ubushushu bento engcolileyo iphantsi kuneqondo lobushushu, ngaloo ndlela kuncitshiswa ingozi yokukhupha kunye nokwaluphala.
Ukongeza, iingubo ezixhaphakileyo zobushushu obuphezulu zikwanazo iipropathi ezibalaseleyo ze-antioxidant, ezinokuthintela i-oxidation yezinto ezinomxholo kumaqondo obushushu aphezulu kunye nokwenziwa kobushushu obuqhelekileyo. Iingubo zeqondo lokunganyangeki eziphezulu zinoluhlu olubanzi lwezicelo. Ingasetyenziselwa ukukhusela izixhobo ezahlukeneyo zensimbi kunye nezingesinyithi, ezinje ngentsimbi, ialuminium alloys, i-ceramics, njl njl, isihlangu se-thermal ". Banokuphawulwa kwimibhobho, ababongikazi, izixhobo, iinjini, iinjini, abatshintshi ubushushu kunye nezinye izixhobo zokunciphisa ilahleko yobushushu, ukuphucula amandla okusebenza kwezixhobo.
Ukongeza, iimoto zokuziphatha ngobushushu ezixhaphakileyo zikwanazo neenguqu zokuziphatha okuhle okusingqongileyo. Bahlala besebenzisa itekhnoloji yokukhuseleka komlilo, enokunciphisa ukusasazeka komlilo kunye nokuvela kweengozi zokhuseleko ngokunyanzeliswa komlilo osebenzayo kunye nedwa. Kwangelo xesha, bahlala behlangabezana neemfuno zoKhuseleko lweSizwe, benza basebenzise kakhulu kwiindawo ezikhululekileyo nezikhuselekileyo zangaphakathi zangaphakathi.
Ngamafutshane, amaqondo obushushuIngubo enganyangekiyo, njengezinto ezikhuselayo, zidlala indima ebalulekileyo kwiindawo zobushushu obuphakamileyo. Banikezela ukhuseleko olusebenzayo olusebenzayo ekubusweni bezinto ezibonakalayo, i-oxidation kunye nokuqhekeka kwe-thermal. Ngokunciphisa ukulahleka kwamandla kunye nokuphucula ukusebenza kwezixhobo, iingubo zeqondo lobushushu ezixhaphakileyo zizisa izibonelelo ezibalulekileyo zoqoqosho nezendalo kumashishini ahlukeneyo. Nokuba kwi-aerospace, amandla okanye amanye amashishini, iingubo ezixhaphakileyo zobushushu ziliqabane elinokuthenjwa kwizinto zokukhusela izixhobo.
