I-NiCu 400 yi-alloy ye-nickel-copper (malunga ne-67% ye-Ni - 23% ye-Cu) ekwazi ukumelana namanzi olwandle kunye nomphunga kumaqondo aphezulu kunye netyuwa kunye nezisombululo ze-caustic. I-alloy 400 yisisombululo esiluqilima esinokuqiniswa kuphela ngokusebenza okubandayo. Le nickel alloy ibonisa iimpawu ezifana nokuxhathisa okulungileyo kokutya, ukukwazi ukuwelda kunye namandla aphezulu. Izinga eliphantsi lokutya kwi-brackish okanye emanzini olwandle aqukuqelayo adityaniswe nokuxhathisa okugqwesileyo kwi-stress-corrosion cracking kuninzi lwamanzi acocekileyo, kunye nokuchasana kwayo neemeko ezahlukeneyo zokubola okukhokelela ekusetyenzisweni kwayo ngokubanzi kwizicelo zaselwandle kunye nezinye izisombululo zekloridi ezingena-oxidizing. Le nickel alloy ixhathisa ngokukodwa kwi-hydro-chloric kunye ne-hydro-fluoric acids xa i-deaerated. Njengoko kuya kulindeleka kumxholo wayo ophezulu wobhedu, i-alloy 400 ihlaselwa ngokukhawuleza yi-nitric acid kunye neenkqubo ze-ammonia.
I-NiCu 400 ineepropati ezinkulu zoomatshini kumaqondo obushushu angaphantsi kwe-subzero, ingasetyenziswa kumaqondo obushushu ukuya kuthi ga kwi-1000 ° F, kwaye indawo yayo yokunyibilika i-2370-2460 ° F. Nangona kunjalo, i-Alloy 400 iphantsi kwamandla kwimeko edibeneyo ngoko, iintlobo ezahlukeneyo zomsindo. ingasetyenziselwa ukwandisa amandla.
Iimpawu zeNiCu 400
- Ukumelana namanzi olwandle kunye nomphunga kumaqondo obushushu aphezulu
- Ukumelana okugqwesileyo kumanzi amdaka aqukuqelayo okanye amanzi olwandle
- Ukuchasana okugqwesileyo kuxinzelelo lwe-corrosion cracking kuninzi lwamanzi acocekileyo
- Ixhathisa ngakumbi kwi-hydro-chloric kunye ne-hydro-fluoric acids xa ziphelile
- Ukuchasana okugqwesileyo kwityuwa engathathi hlangothi kunye ne-alkaline kunye nokuchasana okuphezulu kwi-alkalis
- Ukuchasana nekloridi kubangele uxinzelelo lwe-corrosion cracking
- Iimpawu ezilungileyo zoomatshini ukusuka kumaqondo obushushu angaphantsi kwe-zero ukuya kuthi ga kwi-1020° F
- Inika ukuxhathisa okuthile kwi-hydro-chloric kunye ne-sulfuric acid kumaqondo obushushu aphakathi kunye noxinzelelo, kodwa ayifane ibe yinto ekhethwayo kwezi asidi.
Le ngxubevange inembali ende yokusetyenziswa njengento enganyangekiyo kwi-corrosion, eqala ekuqaleni kwenkulungwane yama-20 xa yaphuhliswa njengelinge lokusebenzisa i-nickel ore ephezulu yobhedu. I-nickel kunye nemixholo yobhedu ye-ore yayikumlinganiselo oqikelelweyo ochazwe ngokusesikweni kwi-alloy.

I-NiCu 400 enganyangekiyo kwi-Corrosion
I-NiCu Alloy 400ikhuselekile kwikloride ion stress corrosion cracking kwiindawo eziqhelekileyo. Ngokuqhelekileyo, ukuxhathisa kwayo ku-corrosion kuhle kakhulu ekunciphiseni okusingqongileyo, kodwa ihlwempu kwiimeko ze-oxidizing. Ayiloncedo kwi-acids oxidizing, njenge-nitric acid kunye ne-nitrous. Nangona kunjalo, iyaxhathisa kwii-alkalis ezininzi, iityuwa, amanzi, iimveliso zokutya, izinto eziphilayo kunye neemeko ze-atmospheric kumaqondo obushushu aqhelekileyo kunye aphakamileyo.
Le nickel alloy ihlaselwa kwiigesi ezithwala isulfure ngaphezulu kwe-700 ° F kwaye isulfure etyhidiweyo ihlasela ialloy kumaqondo obushushu angaphezulu kwama-500 ° F.
I-NiCu 400 inikezela malunga nokuxhathisa okufanayo kwe-corrosion njenge-nickel kodwa kunye noxinzelelo oluphezulu lokusebenza kunye namaqondo okushisa kunye nexabiso eliphantsi ngenxa yobuchule bayo obuphezulu bokwenziwa ngoomatshini.

NiCu 400 Fabrication
I-NiCu Alloy 400 inokudityaniswa ngokulula nge-gas-tungsten arc, i-arc yensimbi yegesi okanye iinkqubo ze-arc zentsimbi ezikhuselweyo zisebenzisa iintsimbi ezifanelekileyo zokuzalisa. Akukho mfuneko yonyango lwe-weld heat heat, nangona kunjalo, ukucocwa ngokucokisekileyo emva kwe-welding kubaluleke kakhulu ekuxhathiseni ukubola, ngaphandle koko kukho umngcipheko wokusuleleka kunye nokuxhamla.
Iimveliso ezigqityiweyo zinokuveliswa kuluhlu olubanzi lweempawu zomatshini xa ulawulo olufanelekileyo lobungakanani bomsebenzi oshushu okanye obandayo kunye nokukhethwa konyango olufanelekileyo lwe-thermal lwenziwa.
Njengazo zonke ezinye ii-alloys ze-nickel, i-NiCu 400 idla ngokuba nzima kumatshini kwaye iya kusebenza nzima. Nangona kunjalo, iziphumo ezigqwesileyo zinokufunyanwa ukuba wenza ukhetho oluchanekileyo lwezixhobo kunye nomatshini.
