Ngophuhliso oluqhubekayo lweshishini kunye nethekhnoloji, izinto ezininzi ezisetyenziswa kwiindawo ezinobushushu obuphezulu zijongene nemingeni enzima.Phantsi kweemeko ezinjalo, i-high-temperature resistant coatings ibe yitekhnoloji eyimfuneko enokuthi inike ukhuseleko olusebenzayo lwe-thermal kwizixhobo ezahlukeneyo kunye nokuqinisekisa ukuzinza kunye nokuqina kwiindawo eziphezulu zokushisa.
Ubushushu obuphezulu obunganyangekiyo yingubo eyilelwe ngokukodwa enokumelana nobushushu obuphezulu.Iyakwazi ukumelana namaqondo obushushu agqithileyo ukusuka kumakhulu ambalwa amadigri celsius ukuya kumawakawaka amaqondo celsius kwaye igcine iimpawu zayo zomzimba kunye nenkangeleko zizinzile ixesha elide.Oku kwenza ukuba iingubo zokumelana nobushushu obuphezulu zibe zikhetho lokuqala kumashishini amaninzi, ngakumbi kwi-aerospace, i-petrochemicals, ukuveliswa kweemoto kunye nokuveliswa kwamandla.
Enye yezona zinto zibalulekileyo zokugquma ubushushu obuphezulu obunganyangekiyo bubushushu obugqwesileyo be-thermal conductivity.Iyakwazi ukufunxa ngokufanelekileyo kwaye iqhube ubushushu ukusuka kumphezulu wento egqunyiweyo, igcina ubushushu bento egqunyiweyo iphantsi kunobushushu be-ambient, ngaloo ndlela inciphisa ngempumelelo umngcipheko wokurhwalala nokuguga.
Ukongezelela, iingubo ezichasene nobushushu obuphezulu nazo zineempawu ezintle kakhulu ze-antioxidant, ezinokuthintela i-oxidation yezinto ezigqunyiweyo kumaqondo okushisa aphezulu kunye nokwakhiwa kweentanda ze-thermal.Iingubo ezichasene nobushushu obuphezulu zinoluhlu olubanzi lwezicelo.Ingasetyenziselwa ukukhusela izinto ezahlukeneyo zetsimbi kunye nezingezona zetsimbi, ezifana nentsimbi, i-aluminium alloys, i-ceramics, njl., esebenza "njengekhaka le-thermal".Ziyakwazi ukugqunywa kwimibhobho, iibhoyili, iziko, iinjini, ukutshintshiselana kobushushu kunye nezinye izixhobo zokunciphisa ngokufanelekileyo ukulahleka kobushushu, ukuphucula ukusebenza kakuhle kwamandla, kunye nokwandisa ubomi benkonzo yezixhobo.
Ukongeza, iingubo zokumelana nobushushu obuphezulu nazo zinokuguquguquka okuhle kokusingqongileyo.Ngokuqhelekileyo basebenzisa iteknoloji yokukhusela umlilo, enokunciphisa ukusasazeka komlilo kunye nokuvela kweengozi zokhuseleko ngokhuseleko lomlilo olusebenzayo kunye nokuhlukaniswa kwe-thermal.Ngexesha elifanayo, bahlala behlangabezana neemfuno zokusingqongileyo, okwenza ukuba basetyenziswe ngokubanzi kwiindawo ezikhululekile nezikhuselekileyo zangaphakathi.
Ngokufutshane, ubushushu obuphezulue-resistant coatings, njengento ebalulekileyo yokukhusela, idlala indima ebalulekileyo kwiindawo eziphakamileyo zokushisa.Banikezela ngokhuseleko olusebenzayo lobushushu ngokuchasene nokuguga kwezinto, i-oxidation kunye nokuqhekeka kwe-thermal.Ngokunciphisa ilahleko yamandla kunye nokuphucula ukusebenza kwezixhobo, ubushushu obuphezulu obunganyangekiyo buzisa inzuzo enkulu yezoqoqosho kunye nokusingqongileyo kumashishini ahlukeneyo.Kungakhathaliseki ukuba kwi-aerospace, amandla okanye amanye amashishini, i-high-temperature resistant coatings iqabane elithembekileyo ekukhuseleni izinto.
