Disebedisweng tsa elektroniki, di-resistor di bapala karolo ya bohlokwa ho laoleng phallo ya motlakase. Ke dikarolo tsa bohlokwa disebedisweng tse tlohang dipotolohong tse bonolo ho isa ho mechini e rarahaneng. Thepa e sebediswang ho etsa di-resistor e ama haholo tshebetso ya tsona, ho tshwarella le bokgoni ba tsona. Har'a tsona, di-alloy tsa tshepe-chromium-aluminium, di-alloy tsa nickel-chromium, le di-alloy tsa koporo-nickel di kgahleha haholo ka lebaka la thepa ya tsona e ikgethang.
Hobaneng ha li-alloy li bapala karolo ea bohlokoa tlhahisong ea li-resistor
Li-alloy ke metsoako ea likarolo tse peli kapa ho feta, bonyane e 'ngoe ea tsona e leng tšepe. Li entsoe ho ntlafatsa litšobotsi tse itseng tse kang matla, ho hanyetsa mafome le botsitso ba mocheso. Litšebelisong tsa resistor, khetho ea alloy e ama coefficient ea mocheso, botsitso le ts'ebetso e akaretsang ea resistor.
Litšobotsi tsa bohlokoa tsa li-alloy tse sebelisoang ho li-resistor ke life?
(1) Khanyetso: Mosebetsi o ka sehloohong oa khanyetso ke ho fana ka khanyetso ho phallo ea motlakase. Khanyetso ea motsoako ke ntlha ea bohlokoa ho fumaneng katleho ea oona ho phetheng mosebetsi ona. 2.
(2) Coefficient ea Thempereichara: Thepa ena e bontša hore na khanyetso ea thepa e fapana hakae ho latela mocheso. Li-resistor li hloka coefficient ea mocheso o tlase oa khanyetso ho netefatsa ts'ebetso e tsitsitseng holim'a mefuta e mengata ea mocheso.
(3) Ho Hanela Tshenyo: Diresistara hangata di pepesehela ditikoloho tse thata. Dialloy tse hanang oxidation le tshenyo di bohlokwa ho bolokeng bophelo le botshepehi ba resistara.
(4) Matla a Mekaniki: Li-resistor li tlameha ho mamella khatello ea 'mele le potoloho ea mocheso. Li-alloy tse nang le matla a phahameng a mekaniki li ka mamella maemo ana ntle le ho senyeha.
(5) Ho Tsitsisa Thempereichara: Bokhoni ba motsoako oa ho boloka thepa ea oona mochesong o phahameng bo bohlokoa haholo-holo lits'ebetsong tse matla a phahameng.
Tšepe ea Chromium Aluminium Alloy - Sebopeho le Matlotlo:
Litšepe tse kopantsoeng tsa tšepe-chromium-aluminium(FeCrAl) li tsebahala ka ho hanyetsa ha tsona ka ho fetisisa oxidation le botsitso ba mocheso o phahameng. Hangata li entsoe ka tšepe, chromium le aluminium, metsoako ena ha e senyehe haholo mochesong o fihlang ho 1400°C (2550°F).
Dikopo ho Resistors:
Li-alloy tsa tšepe-chromium-aluminium li sebelisoa haholo ho li-resistor tsa mocheso o phahameng, haholo-holo lits'ebetsong tse latelang:
- Dikarolo tsa ho Futhumatsa: Tšepe Chromium Di-alloy tsa aluminium di sebediswa hangata e le dikarolo tsa ho futhumatsa ka diontong tsa diindasteri le diontong ka lebaka la bokgoni ba tsona ba ho boloka botsitso ba sebopeho maemong a lehodimo.
- Li-resistors tsa motlakase: Li-alloy tsena li boetse li sebelisoa ho li-resistors tsa motlakase tse hlokang botsitso bo phahameng ba mocheso le khanyetso ea oxidation.
- Ditshebediso tsa dikoloi: Disebedisweng tsa elektroniki tsa dikoloi, di-alloy tsa FeCrAl di sebediswa ho di-resistor tse sebetsang dibakeng tse nang le mocheso o phahameng, jwalo ka ditsamaiso tsa mosi.
Li-Alloys tsa Nickel-Chromium - Sebopeho le Matlotlo:
Li-alloy tsa nickel-chromium (NiCr) ke khetho e 'ngoe e tsebahalang bakeng sa lits'ebetso tsa resistor. Li-alloy tsena hangata li entsoe ka nickel le chromium, peresente ea tsona e itšetlehile ka litšobotsi tse lakatsehang.Litšepe tsa NiCrli tsebahala ka ho hanyetsa ha tsona hantle, ts'ebetso ea mocheso o phahameng le ho hanyetsa mafome.
Hangata ho sebelisoa li-alloy tsa Nichrome:
- Li-Resistors tsa Filimi: Li-resistors tsena li sebelisoa lits'ebetsong moo ho nepahala ho leng bohlokoa le moo motsoako oa NiCr o fanang ka botsitso bo hlokahalang le coefficient e tlase ea mocheso.
- Li-Resistor tsa Maqeba a Lithapo: Ho li-resistors tsa maqeba a lithapo, terata ea Nichrome e atisa ho sebelisoa ka lebaka la khanyetso ea eona e phahameng le bokhoni ba ho mamella potoloho ea mocheso.
- Ditshebediso tsa Mocheso o Phahameng: Jwalo ka di-alloy tsa ferrochromium-aluminium, di-alloy tsa nickel-chromium di loketse dibaka tsa mocheso o phahameng, e leng se etsang hore di be ntle bakeng sa ditshebediso tsa diindasteri le tsa difofane.
Litšepe tse kopantsoeng tsa koporo le nickel - sebopeho le thepa
Li-alloy tsa koporo-nickel (CuNi) li tsebahala ka ho tsamaisa motlakase hantle le ho hanyetsa mafome. Li-alloy tsena hangata li na le koporo le nickel, tse nang le thepa e itseng e fihlellehang ka ho fetola dikahare tsa nickel. Li-alloy tsa CuNi li ananeloa haholo ka lebaka la bokhoni ba tsona ba ho boloka ts'ebetso libakeng tsa leoatle le tse ling tse senyang.
Li-alloy tsa koporo le nickel li sebelisoa lits'ebetsong tse fapaneng tsa resistor, ho kenyeletsoa:
- Li-Resistors tse Hlokahalang ka ho Sebetsa: Ka lebaka la ho tsamaisa le ho tsitsisa ha tsona hantle,Li-alloy tsa CuNihangata li sebelisoa bakeng sa li-resistor tse nepahetseng lits'ebetsong tsa ho lekanya le taolo.
- Ditshebediso tsa lewatle: Ho hanela ho bola ha di-alloy tsa CuNi ho etsa hore di lokele di-resistor tse sebediswang dibakeng tsa lewatle moo ho pepesehela metsi a letswai ho ka bang kotsi.
- Ditshebediso tsa Mocheso o Tlase: Di-alloy tsa koporo le nickel di sebetsa hantle dibakeng tse nang le cryogenic, e leng se etsang hore di be ntle bakeng sa ditshebediso tsa mocheso o tlase.
Li-alloy tsa FeCrAl, nichrome, le koporo-nickel kaofela li na le thepa e ikhethang e etsang hore li lokele lits'ebetso tse fapaneng.
- Li-alloy tsa tšepe-chromium-aluminium li sebetsa hantle libakeng tse nang le mocheso o phahameng 'me li loketse hantle bakeng sa lintho tse futhumatsang le li-resistors tsa motlakase.
- Li-alloy tsa nickel-chromium li fana ka botsitso bo botle le ho hanyetsa mafome 'me li loketse li-resistor tsa filimi le tsa terata.
- Li-alloy tsa koporo-nickel li tsebahala ka ho khanna ha tsona ka lebelo le phahameng le ho hanyetsa mafome 'me li loketse hantle bakeng sa li-resistor tse nepahetseng le lits'ebetso tsa metsing.
