Kuma-electronics, ama-resistors adlala indima ebalulekile ekulawuleni ukugeleza kwamandla. Ziyizingxenye ezibalulekile kumadivayisi asukela kumasekethe alula ukuya emishinini eyinkimbinkimbi. Izinto ezisetshenziselwa ukukhiqiza ama-resistors zithinta kakhulu ukusebenza kwazo, ukuqina nokusebenza kahle kwazo. Phakathi kwazo, ama-alloys e-iron-chromium-aluminium, ama-nickel-chromium alloys, nama-alloys e-copper-nickel anesithakazelo esikhulu ngenxa yezakhiwo zawo eziyingqayizivele.
Kungani ama-alloys edlala indima ebalulekile ekwenziweni kwe-resistor
Ama-alloys ayinhlanganisela yezinto ezimbili noma ngaphezulu, okungenani eyodwa yazo eyinsimbi. Zenzelwe ukuthuthukisa izakhiwo ezithile njengamandla, ukumelana nokugqwala kanye nokuzinza kwe-thermal. Kuzinhlelo zokusebenza ze-resistor, ukukhethwa kwe-alloy kuthinta i-coefficient yokushisa, ukuzinza kanye nokusebenza okuphelele kwe-resistor.
Yiziphi izici ezibalulekile zama-alloys asetshenziswa kuma-resistors
(1) Ukumelana: Umsebenzi oyinhloko we-resistor ukunikeza ukumelana nokugeleza kwamandla. I-resissisivity ye-alloy iyisici esibalulekile ekunqumeni ukusebenza kahle kwayo ekwenzeni lo msebenzi. 2.
(2) I-Temperature Coefficient: Lesi sici sibonisa ukuthi kungakanani ukumelana kwento ehluka ngokwezinga lokushisa. Ama-resistors adinga i-coefficient ephansi yezinga lokushisa lokumelana ukuze kuqinisekiswe ukusebenza okuzinzile phezu kwebanga elibanzi lokushisa.
(3) I-Corrosion Resistance: I-Resistors ivame ukuchayeka ezindaweni ezinokhahlo. Ama-alloys amelana ne-oxidation kanye nokugqwala abalulekile ekugcineni impilo nokuthembeka kwe-resistor.
(4) Amandla Emishini: Abamelene nokucindezeleka ngokomzimba kanye nokuhamba ngebhayisikili okushisayo. Ama-alloys anamandla amakhulu emishini angakwazi ukumelana nalezi zimo ngaphandle kokuwohloka.
(5) Ukuzinza Kwe-Thermal: Ikhono le-alloy ukugcina izakhiwo zalo emazingeni okushisa aphakeme kubalulekile, ikakhulukazi ekusetshenzisweni kwamandla aphezulu.
I-Iron Chromium Aluminium Alloy - Ukwakheka Nezakhiwo:
Ama-alloys e-iron-chromium-aluminium(FeCrAl) zaziwa ngokumelana kwazo kahle ne-oxidation kanye nokuzinza kwezinga lokushisa eliphezulu. Ngokuvamile akhiwa insimbi, i-chromium ne-aluminium, lawa ma-alloys awawoli ngokuphawulekayo emazingeni okushisa afika ku-1400°C (2550°F).
Izicelo ku-Resistors:
Ama-alloys e-iron-chromium-aluminium asetshenziswa kabanzi kuma-high-temperature resistors, ikakhulukazi kulezi zicelo ezilandelayo:
- Izinto Zokushisisa: Ama-alloys e-Iron Chromium Aluminium avame ukusetshenziswa njengezici zokushisisa ezithandweni zezimboni namahhavini ngenxa yekhono lawo lokugcina ubuqotho besakhiwo emazingeni okushisa aphezulu.
- Izihluthulelo zamandla: Lawa ma-alloys asetshenziswa futhi kuma-resistors amandla adinga ukuzinza okuphezulu kokushisa nokumelana ne-oxidation.
- Izinhlelo zokusebenza zezimoto: Kumishini kagesi yezimoto, ama-alloys e-FeCrAl asetshenziswa ezintweni eziphikisayo ezisebenza ezindaweni ezishisa kakhulu, njengezinhlelo zokukhipha umoya.
I-Nickel-Chromium Alloys - Ukwakheka Nezakhiwo:
Ama-alloys e-nickel-chromium (NiCr) angenye inketho edumile yezinhlelo zokusebenza eziphikisayo. Lawa ma-alloys ngokuvamile akhiwa i-nickel ne-chromium, iphesenti lakho elincike ezicini ezifunwayo.Ama-alloys e-NiCrzaziwa ngokumelana kwazo okuhle kakhulu, izinga lokushisa eliphezulu nokumelana nokugqwala.
Ama-alloys e-Nichrome asetshenziswa kakhulu:
- I-Film Resistors: Lezi ziphikisa zisetshenziswa ezinhlelweni lapho ukunemba kubaluleke khona nalapho ingxubevange ye-NiCr inikeza ukuzinza okudingekayo kanye ne-coefficient ephansi yezinga lokushisa.
- I-Wirewound Resistors: Ku-wirewound resistors, intambo ye-Nichrome ivame ukusetshenziswa ngenxa yokumelana kwayo okuphezulu nekhono lokumelana nokuhamba ngebhayisikili okushisayo.
- Izicelo Zezinga Lokushisa Ephakeme: Ngokufanayo nama-alloys e-ferrochromium-aluminium, ama-alloys e-nickel-chromium afanele izindawo zokushisa okuphezulu, okuwenza alungele ukusetshenziswa kwezimboni kanye ne-aerospace.
Ama-alloys e-Copper-nickel - ukwakheka kanye nezakhiwo
Ama-alloys e-Copper-nickel (CuNi) aziwa ngokusebenza kwawo okuhle kakhulu kagesi kanye nokumelana nokugqwala. Lawa ma-alloys ngokuvamile aqukethe ithusi ne-nickel, enezici ezithile ezifinyelelwa ngokuhlukahluka kokuqukethwe kwe-nickel. Ama-alloys e-CuNi aziswa kakhulu ngekhono lawo lokugcina ukusebenza olwandle nakwezinye izindawo ezigqwalile.
Ama-alloys e-Copper-nickel asetshenziswa ezinhlobonhlobo ze-resistor application, kufaka phakathi:
- I-Precision Resistors: Ngenxa yokusebenza kwayo okuhle kakhulu nokuzinza,Ama-alloys e-CuNizivame ukusetshenziselwa ukunemba kokumelana nezinhlelo zokusebenza zokulinganisa nokulawula.
- Izicelo zasolwandle: Ukumelana nokugqwala kwama-alloys e-CuNi kuwenza afanelekele izinto eziphikisayo ezisetshenziswa ezindaweni zasolwandle lapho ukuchayeka emanzini anosawoti kungaba yingozi.
- Izicelo Zezinga Lokushisa Eliphansi: Ama-alloys e-Copper-nickel enza kahle endaweni ye-cryogenic, okuwenza alungele ukusetshenziswa kwezinga lokushisa eliphansi.
I-FeCrAl, i-nichrome, ne-copper-nickel alloys zonke zinezici ezihlukile ezizenza zifanelekele izinhlelo zokusebenza ezihlukahlukene.
- Ama-alloys e-Iron-chromium-aluminium asebenza kahle ezindaweni ezinezinga eliphezulu lokushisa futhi afaneleka kahle ezintweni zokushisisa nezimbangi zamandla.
- Ama-alloys e-nickel-chromium ahlinzeka ngokuzinza okuhle kakhulu nokumelana nokugqwala futhi afanele ifilimu ne-wirewound resistors.
- Ama-alloys e-Copper-nickel aziwa ngokusebenza kwawo okuphezulu kanye nokumelana nokugqwala futhi afaneleka kahle ukumelana nokunemba kanye nezicelo zasolwandle.
