Tlhaloso e Felletseng ea Phapano

1. Sebopeho sa Lik'hemik'hale & Ts'ebetso ea Core

Phapang ea mantlha e ho karolelano ea nickel-chromium: Nicr7030 e na le 30% chromium (e holimo ho Nicr8020's 20%), e ntlafatsang ductility le weldability ea eona. Ka nako ea khefu ea ≥25%, Nicr7030 e ka huleloa ka lithapo tse ntle haholo (ho fihla ho 0.01mm) kapa ea kobeha ka libopeho tse rarahaneng, e leng se etsang hore e be se loketseng bakeng sa lihlahisoa tse hlokang ho sebetsa hantle (mohlala, lithapo tsa ho futhumatsa setulo sa koloi, li-sensor tsa elektroniki tse nyane).

Ka lehlakoreng le leng, Nicr8020 e phahameng ea nickel content (80%) e ntlafatsa botsitso ba eona ba mocheso o phahameng, e lumella hore e sebetse ka ho tsoelang pele ho 1300°C—50°C ho feta Nicr7030. Leha ho le joalo, sena se tla ka litšenyehelo tsa ho fokotsa ductility (feela ≥15%), e leng se etsang hore e se ke ea tšoaneleha bakeng sa ho koba kapa ho etsa mekhoa. Mefuta e meng e joalo ka Nicr6040 e na le litaba tse tlase tsa nickel, e bakang ho hanyetsa ho tlase le ho hanyetsa mocheso, ho fokotsa ts'ebeliso ea eona maemong a batloang haholo.

2. Resistivity & Matla a Matla

Resistivity e ama ka ho toba katleho ea mocheso le moralo oa likarolo. Nicr8020 e na le resistivity e phahameng (1.40 Ω·mm²/m), ho bolelang hore e hlahisa mocheso o mongata ka bolelele ba yuniti ka tlas'a motlakase o tšoanang, e etsa hore e tšoanelehe bakeng sa lisebelisoa tse futhumatsang tse nang le matla a phahameng (mohlala, libopi tsa mocheso o phahameng oa sintering).

Nicr7030's "Restivity" e itekanetseng (1.18 Ω·mm²/m) e etsa hore ho be le botsitso lipakeng tsa ho hlahisa mocheso le tšebeliso ea matla. Bakeng sa lisebelisoa tse ngata tsa indasteri le tsa bareki (mohlala, lionto, lisebelisoa tsa ho futhumatsa), e fana ka matla a lekaneng a ho futhumatsa ha e ntse e fokotsa litšila tsa matla. Ho phaella moo, resistivity ea eona e tsitsitseng (± 0.5% mamello) e tiisa ts'ebetso e tsitsitseng ka nako e telele, ho qoba ho fetoha ha mocheso.

3. Oxidation Resistance & Service Life

Ka bobeli Nicr7030 le Nicr8020 li etsa lifilimi tse sireletsang tsa Cr₂O₃ mochesong o phahameng, empa litaba tsa chromium tse phahameng tsa Nicr7030 li etsa filimi e thata, e tšoarellang ho feta. Sena se etsa hore e hanane le "bola bo botala" (intergranular oxidation) sebakeng se mongobo kapa se fokolang, se eketsa bophelo ba ts'ebeletso ho lihora tse 8000+ (20% e telele ho feta Nicr8020 libakeng tse thata).

Nicr6040, e nang le dikahare tse tlase tsa chromium, e na le filimi ea oxide e tsitsitseng e sa tsitsang e tloaetseng ho ebola ka mocheso o ka holimo ho 1000 ° C, e lebisang ho khutsufatso ea bophelo ba ts'ebeletso le ho eketseha ha litšenyehelo tsa tlhokomelo.

4. Litšenyehelo & Ho ikamahanya le maemo a Kopo

Nicr7030 e fana ka ts'ebeliso e ntle ea litšenyehelo: litaba tsa eona tse tlase tsa nickel (ha li bapisoa le Nicr8020) li fokotsa litšenyehelo tsa thepa e tala ka 15-20%, ha ts'ebetso ea eona e fapaneng e akaretsa 80% ea maemo a kopo ea terata ea nichrome. Ke khetho e ratoang bakeng sa lihlahisoa tse hlahisoang ka bongata joalo ka lisebelisoa tsa lapeng le lisebelisoa tsa ho futhumatsa likoloi, moo ho leka-lekanya ts'ebetso le litšenyehelo li leng bohlokoa.

Nicr8020 ea nickel e phahameng e eketsa litšenyehelo tsa eona, e etsa hore e hlokehe bakeng sa lisebelisoa tse khethehileng tsa mocheso o phahameng (mohlala, tlhahlobo ea likarolo tsa sefofane). Mefuta e meng ea nickel e tlase joalo ka Nicr6040 e theko e tlase empa e haelloa ke ts'ebetso ho fihlela litlhoko tsa indasteri kapa tse nepahetseng tsa elektroniki.

Tataiso ea Khetho

• Khethanicr7030ha o hloka: Ts'ebetso e fapaneng, ts'ebetso e bonolo (ho kobeha / welding), ho boloka litšenyehelo, le ts'ebeliso ea lisebelisoa tsa ntlo, ho futhumatsa likoloi, ho futhumatsa indasteri, kapa lisebelisoa tsa elektroniki tse nepahetseng.
• Khethanicr8020ha o hloka: Mocheso o phahameng oa ts'ebetso (1300 ° C+) le lisebelisoa tse futhumatsang tse nang le matla a phahameng (mohlala, libopi tse khethehileng tsa indasteri).
• Khetha mefuta e meng (mohlala, Nicr6040) feela bakeng sa maemo a tlase a mocheso, a batloang haholo (mohlala, lihanyetsi tsa mantlha).

Ka ts'ebetso ea eona e leka-lekaneng, katleho ea litšenyehelo, le ho ikamahanya le maemo ho pharaletseng, Nicr7030 ke khetho e theko e boima ka ho fetisisa ho bareki ba bangata. Khamphani ea rona e fana ka litlhaloso tse ikhethileng (bophara, bolelele, sephutheloana) le tšehetso ea tekheniki ho netefatsa hore Nicr7030 e lumellana hantle le litlhoko tsa hau tsa kopo.
