Kutheni iiNickel ezisekwe kwiiAlloys?

Iialloys ezisekwe kwiNickel

I-alloys esekwe kwi-Nickel ikwabizwa ngokuba zii-superalloys ezisekwe kwi-ni ngenxa yamandla azo aqaqambileyo, ukumelana nobushushu kunye nokumelana nomhlwa. Ubume bekristale obujolise ebusweni luphawu olwahlukileyo kwii-alloys ezisekwe kwi-ni kuba i-nickel isebenza njengesiqinisi se-austenite.

Izinto ezongezelelweyo eziqhelekileyo zemichiza kwii-alloys ezisekwe kwi-nickel zii-chromium, cobalt, molybdenum, iron kunye ne-tungsten.

I-Inconel® kunye neHastelloy® Nickel esekwe kwiiAlloys

Iintsapho ezimbini ezisekwe kwi-nickel esekwe kwi-alloys zii-Inconel® kunye neHastelloy®. Abanye abavelisi abaziwayo yiWaspaloy®, iAllvac® kunye noMbane Jikelele.

Ezona alloys zixhaphakileyo ezisekwe kwi-nickel ze-Incelel zezi:

• Inconel® 600, 2.4816 (72% Ni, 14-17% Cr, 6-10% Fe, 1% Mn, 0.5% Cu): I-nickel-chrome-iron alloy ebonisa uzinzo olugqwesileyo kwisikali sobushushu ngokubanzi. Uzinzile ngokuchasene neklorine kunye namanzi eklorini.
• Inconel® 617, 2.4663 (ibhalansi yeNickel, 20-23% Cr, 2% Fe, 10-13% Co, 8-10% Mo, 1.5% Al, 0.7% Mn, 0.7% Si): Le alloy yenziwe ikakhulu nge-nickel , I-chrome, i-cobalt kunye ne-molybdenum ibonisa amandla aphezulu kunye nokuchasana nobushushu.
• Inconel® 718 2.4668 (50-55% Ni, 17-21% Cr, Iron balance, 4.75-5.5% Nb, 2.8-3.3% Mo, 1% Co,): I-nickel-chrome-iron-molybdenum alloy enzima Yaziwa ngokusebenza kwayo kakuhle kunye neempawu ezintle zoomatshini kumaqondo obushushu asezantsi.

I-Hastelloy® i-nickel-based alloys iyaziwa ngokuchasene ne-acid. Ezona zixhaphakileyo zezi:

• IHastelloy® C-4, 2.4610 (ibhalansi yeNickel, 14.5 - 17.5% Cr, 0 - 2% Co, 14 - 17% Mo, 0 - 3% Fe, 0 - 1% Mn): C-4 yi-nickel- chrome-molybdenum alloy esetyenziswa kwimimandla ene-asidi engaphiliyo.
• IHastelloy® C-22, 2.4602 (ibhalansi yeNickel, 20 -22.5% Cr, 0 - 2.5% Co, 12.5 - 14.5% Mo, 0 - 3% Fe, 0-0.5% Mn, 2.5 -3.5 W): C- I-22 yi-nickel-chrome-molybdenum-tungsten alloy enganyangekiyo ebonakalisa ukuzingisa okuhle ngokuchasene neasidi.
• I-Hastelloy® C-2000, i-2.4675 (ibhalansi yeNickel, 23% Cr, 2% Co, 16% Mo, 3% Fe): C-2000 isetyenziswa kwimimandla enezidibanisi ezinobundlongondlongo, ezinjenge-sulfuric acid kunye ne-ferric chloride.

♦ Ukuphucula ukuzinza kwamaqhekeza asekwe kwi-nickel

I-alloys esekwe kwi-Nickel yaziwa ngokuba ziipropathi zoomatshini ezigqwesileyo ezinje ngokuchasa umhlwa kunye nozinzo lobushushu obuphezulu. Nangona kunjalo, phantse akukho siqwenga somsebenzi sinokuhlala ngonaphakade, nokuba sihle kangakanani isixhobo. Ukwandisa ixesha lokuphila kwamalungu, ii-alloys ezisekwe nge-nickel zinokunyangwa ngeBoroCoat®, unyango lwethu lokusasaza ukuphucula umhlwa kunye nokunxiba ukuxhathisa kunye nokubonelela ngozinzo ngokuchasene neeoksijini.

Umaleko wokusasazeka kweBoroCoat® uphucula ubunzima bomhlaba ukuya kuthi ga kwi-2600 HV ngelixa ugcina umaleko wokusasazeka we-60 µm. Ukuxhathisa ukunxiba kuphuculwe kakhulu, njengoko kungqinwa yipini kuvavanyo lweediski. Ngelixa ubunzulu bokunxiba ii-alloys ezingasetyenziswanga ze-nickel zonyusa ixesha elide xa ujikeleza, ii-alloys ezisekwe kwi-ni kunye neBoroCoat® zibonisa ubunzulu obunxibayo obunxibayo kuvavanyo.

♦ Iindawo zokuSebenza

Ialloys ezinesiseko se-nickel zihlala zisetyenziswa kwiindawo ezinobunzima ezifuna ukumelana nokuchasana namaqondo aphezulu kunye neqondo eliphantsi, igcwala / umhlwa kunye namandla aphezulu. Yiyo loo nto izicelo zibandakanya kodwa zingaphelelanga: ubunjineli beinjini, iteknoloji yezityalo, ishishini lamachiza, ubunjineli beenqwelo moya kunye neevaluva / izixhobo.

 Phantse iipesenti ezingama-60 ze-nickel ehlabathini iphela njengenxalenye yensimbi engenasici. Ikhethwe ngenxa yamandla ayo, ubunzima, kunye nokumelana nokubola. I-Duplex steels ezingenasici ziqulethe malunga ne-5% ye-nickel, i-austenitics malunga ne-10% ye-nickel, kunye ne-super austenitics ngaphezulu kwama-20% Amanqanaba okumelana nobushushu ahlala ene-nickel engaphezulu kwama-35%. I-alloys esekwe kwi-Nickel ngokubanzi ine-50% ye-nickel okanye nangaphezulu.
