I-Nickel Base Alloy ene-oxidation kunye ne-corrosion resistant
Isicelo
I-nickel base alloy powder yinto ephezulu yokusebenza esetyenziswa ngokubanzi kumashishini ahlukeneyo, ngakumbi kwiindawo eziphakamileyo zokushisa kunye neendawo ezinobungozi.Ukuchasana kwayo kakuhle kwe-corrosion kunye ne-high-temperature oxidation resistance yenza kube lukhetho oludumileyo lweengubo kwintsimbi kunye neengxenye zetsimbi eziphantsi phantsi kweemeko eziphezulu zokushisa.Ikwasetyenziswa njengesigaba sokubopha i-carbide coating, iyenza ibe lolona khetho lufanelekileyo kwizicelo zokunxiba.
Iipropati
Umgubo wenziwa nge-nickel, ichromium, kunye nezinye izinto, ezinika ukuxhathisa okugqwesileyo kokutya kunye nokuzinza kobushushu obuphezulu.Umgubo unokwenza i-coating enokusebenza kumaqondo obushushu ukuya kuthi ga kwi-980ºC, iyenze ilungele ukusetyenziswa kwiindawo ezirhabaxa.Ukwaleka kukwanokuqina okulungileyo kunye nokusebenza koomatshini, okwenza kube yinto efanelekileyo yokusetyenziswa kwizicelo zokunxiba.
Ukwenziwa kwemveliso
I-nickel base alloy powder iveliswa ngokusebenzisa inkqubo ye-atomization yegesi.Inkqubo ibandakanya ukunyibilika kwezinto eziluhlaza kwaye emva koko zifakwe kwi-athomu ibe ngumgubo ocolekileyo usebenzisa igesi yoxinzelelo oluphezulu.Umgubo obangelwayo unobukhulu obufanayo kunye nokuhamba kakuhle, okwenza kube lula ukuphatha kunye nokusebenza.
Ukusetyenziswa
I-nickel base alloy powder isetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanywa i-aerospace, ukuveliswa kwamandla, kunye nokulungiswa kweekhemikhali.Ngokuqhelekileyo isetyenziswe njengento yokugubungela ukukhusela insimbi kunye neengxenye zetsimbi eziphantsi kwe-alloy phantsi kobushushu obuphezulu kunye neemeko ezinobungozi.Ikwasetyenziswa njengesigaba sokubopha i-carbide coating, iyenza ibe yinto efanelekileyo kwizicelo zokunxiba.Umgubo ungasetyenziswa kusetyenziswa iinkqubo ezahlukeneyo zokutshiza nge-thermal, kubandakanywa isitshizi somlilo, isitshizi seplasma, kunye nesantya esiphezulu se-oxy-fuel (HVOF) yokutshiza.
Ukuqukumbela
I-nickel base alloy powder yinto ephezulu yokusebenza esetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokumelana nokugqwala okugqwesileyo kunye nokushisa okuphezulu kwe-oxidation.Inkqubo ye-atomization yegesi iqinisekisa ukuba umgubo unobungakanani obufanayo be-particle kunye nokuhamba kakuhle, okwenza kube lula ukuphatha kunye nokusebenza.Ukuzinza kwayo okuphezulu kobushushu, ukuqina, kunye nokusebenza koomatshini kuyenza ibe lolona khetho lufanelekileyo lokusetyenziswa kwiindawo ezirhabaxa kunye nezicelo zokunxiba.
