Intshayelelo

Kwixesha lanamhlanje lomveliso ophambili kunye nobunjineli bemizi mveliso,Amaqondo obushushu aphezulu ngentsimbiDlala indima ebaluleke kakhulu kwizicelo ezibalulekileyo apho kukho isifo se-thermal, ukumelana nokucoca, kunye nokugcina ingqibelelo kubalulekile. La macandelo anenjineli ngokukodwa ukuba enze phantsi kweemeko ezigqithisileyo, ezenza ukuba babe nakho kumashishini anjenge-aerospace, inqwelo-mafutha, ukuhanjiswa kwamandla, kunye ne-metallger, nangaphezulu.

Eli nqaku lipheleleyo liphonononga ubume, izibonelelo, izicelo, ukhetho lwezinto ezibonakalayo, kunye nokulungisa amandla ezinto eziphezulu zentsimbi eziPhezulu. Ikwaxoxa ngesizathu sokuba izisombululo ezenziwe ngokwezifiso zibalulekile kwaye ababenzi bahlangabezana njani neemeko eziphakamileyo zobushushu.

Ngawaphi amaqondo obushushu aphezulu anganyangekiyo anganyangekiyo?

Amaqondo obushushu amaqondo obushushu anganyangekiyozizinto ezenziwe zivela kumabakala ensimbi eliqinisekileyo eligcina amandla, ukumelana ne-oxidation, kunye nozinzo lobushushu obuphakamileyo. La macandelo ayilelwe ukuba anyamezele ukuvezwa kwexesha elide kwimeko enobushushu-ngokuqhelekileyo ukusuka kwi-500 ° C) ukuya ngaphezulu kwe-1100 ° 2 ° F (2012 ° F) -Ukulahlekelwa, okanye ukuphulukana nezakhono zabo zentsebenzo.

Ngokungafaniyo nentsimbi engaqhelekanga, ezi zinto zixhaphaza ubushushu zabelwa ngezinto ezinjeIChromium, i-Nickel, Molybdenum, Tungsten, kunye neCobabat, ephucula ukunyamezelana kwabo kunye nokunyaniseka kwesakhiwo phantsi kobushushu obuqatha.

Iipropathi eziphambili zamacandelo entsimbi enganyangekiyo

Izinto zentsimbi ezingenasitali ezenzelwe ukuba izicelo zeqondo eliphezulu kufuneka zibonise ezi mpawu zilandelayo:
