Ntlha ea pele, ke habohlokoa ho hlokomela likamano tsa bona:Nichrome(e khuts'oane bakeng sa motsoako oa nickel-chromium) ke sehlopha se pharaletseng sa li-alloys tse thehiloeng ho nickel-chromium, haNi80ke mofuta o itseng oa nichrome o nang le sebopeho se tsitsitseng (80% nickel, 20% chromium). "Phapang" e ka "general category vs. specific variant" — Ni80 ke ea lelapa la nichrome empa e na le thepa e ikhethang ka lebaka la e tsitsitseng, e etsang hore e tšoanelehe bakeng sa maemo a khethehileng a mocheso o phahameng. Ka tlase ke papiso e qaqileng:
| Karolo | Nichrome (Sehlopha se Akaretsang) | Ni80 (Specific Nichrome Variant) |
| Tlhaloso | Lelapa la li-alloys haholo-holo le entsoe ka nickel (50-80%) le chromium (10-30%), e nang le li-additives tsa boikhethelo (mohlala, tšepe) | Phapang ea premium nichrome e nang le sebopeho se thata: 80% nickel + 20% chromium (ha ho na li-additives) |
| Sebopeho Ho Fetolana | Mefuta e fapaneng ea nickel-chromium (mohlala, Ni60Cr15, Ni70Cr30) ho fihlela litlhoko tse fapaneng | E tsitsitse karo-karolelano ea 80:20 nickel-chromium (ha ho na ho feto-fetoha ha likarolo tsa mantlha) |
| Ts'ebetso ea Bohlokoa | Ho hanyetsa mocheso o phahameng (800-1000 ° C), khanyetso ea mantlha ea oxidation, le khanyetso ea motlakase e feto-fetohang. | Ho hanyetsa mocheso o phahameng haholo (ho fihla ho 1200 ° C), khanyetso e ntle ea oxidation (sekala se tlase ho 1000 ° C+), le khanyetso e tsitsitseng ea motlakase (1.1–1.2 Ω/mm²) |
| Lisebelisoa tse Tloaelehileng | Maemo a ho futhumatsa mocheso o tlase-tlase (mohlala, li-tubes tse futhumatsang lisebelisoa tsa ka tlung, lihitara tse nyane, lihitara tse nang le matla a tlase a indasteri) | Mocheso o phahameng, maemo a batloang haholo (mohlala, likhoele tsa sebōpi sa indasteri, lithapo tse chesang tsa printa ea 3D, lisebelisoa tsa ho tlosa leqhoa) |
| Mefokolo | Mocheso o ka tlaase ho fetisisa; tshebetso e fapana ho ya ka karo-karolelano e itseng (mefuta e meng e oxidize ka potlako nakong ya mocheso o phahameng) | Litsenyehelo tse phahameng tsa thepa e tala; e tšoanelehang haholo bakeng sa maemo a mocheso o tlase (ha e boloke litšenyehelo) |
1. Sebopeho: Fixed vs. Flexible
Nichrome e le sehlopha e lumella litekanyetso tse feto-fetohang tsa nickel-chromium ho leka-lekanya litšenyehelo le ts'ebetso. Ka mohlala, Ni60Cr15 (60% Ni, 15% Cr) e eketsa tšepe ho fokotsa litšenyehelo empa e fokotsa ho hanyetsa mocheso. Ka lehlakoreng le leng, Ni80 e na le tekanyo ea 80: 20 nickel-chromium e ke keng ea buisanoa-kahare ena e phahameng ea nickel ke ka lebaka leo e fetang mefuta e meng ea nichrome ho hanyetsa oxidation le ho mamella mocheso. Ni80 ea rona e khomarela ka tieo maemo a 80:20, ka ho nepahala ha sebopeho ka hare ho ± 0.5% (e lekoa ka pono ea atomic absorption spectroscopy).
2. Tshebetso: E kgethehileng vs. Kakaretso-Morero
Bakeng sa litlhoko tsa mocheso o phahameng (1000-1200 ° C), Ni80 ha e bapisoe. E boloka botsitso ba sebopeho litsing tsa liindasteri kapa lipheletsong tse chesang tsa khatiso ea 3D, ha nichrome e 'ngoe (mohlala, Ni70Cr30) e ka qala ho oxidizing kapa ho holofala ho feta 1000 ° C. Leha ho le joalo, bakeng sa mesebetsi ea mocheso oa bohareng ba mocheso (mohlala, heater ea moriri oa moriri oa 600 ° C), ho sebelisa Ni80 ha ho hlokahale - mefuta e theko e tlaase ea nichrome e sebetsa hantle. Mohala oa rona oa lihlahisoa o akaretsa Ni80 ka bobeli (bakeng sa maemo a batloang haholo) le nichrome e 'ngoe (bakeng sa litlhoko tsa theko e tlase, tse tlase mocheso).
3. Kopo: Targeted vs. Wide-Ranging
Mokhahlelo o pharalletseng oa Nichrome o fana ka litlhoko tse fapaneng tsa mocheso o tlase ho isa bohareng: Ni60Cr15 bakeng sa lihitara tse nyane tsa malapa, Ni70Cr30 bakeng sa likhoele tsa likhoerekhoere tsa khoebo. Ni80, ka lehlakoreng le leng, e shebana le lits'ebetso tse phahameng haholo, tse nang le mocheso o phahameng: e fana ka matla a libono tsa sintering tsa indasteri (moo ho ts'oana ha mocheso ho bohlokoa) le litsamaiso tsa aerospace de-icing (moo ho hanyetsanang le lipotoloho tse batang haholo / tse chesang ho hlokahalang). Ni80 ea rona e netefalitsoe bakeng sa ASTM B162 (litekanyetso tsa sefofane) le ISO 9001, e netefatsang ho ts'epahala maemong ana a boima.
Mokhoa oa ho khetha pakeng tsa bona?
- Khetha nichrome e akaretsang (mohlala, Ni60Cr15, Ni70Cr30) haeba: U hloka ho futhumatsa mocheso oa bohareng ba mocheso o tlase (<1000°C) 'me u behe pele ho boloka litšenyehelo (mohlala, lisebelisoa tsa ka tlung, lihitara tse nyenyane).
- Khetha Ni80 haeba: U hloka botsitso ba mocheso o phahameng (> 1000 ° C), bophelo bo bolelele ba ts'ebeletso (lihora tse 10,000+), kapa u sebetsa liindastering tsa bohlokoa (sefofane, tlhahiso ea indasteri).
Sehlopha sa rona se fana kaditherisano tsa mahala- re tla u thusa ho tsamaisana le mofuta o nepahetseng oa nichrome (ho kenyeletsoa Ni80) le sesebelisoa sa hau se ikhethileng, ho netefatsa ts'ebetso e nepahetseng le ts'ebeliso e ntle ea litšenyehelo.
