Kwe-elekthronikhi, abaphikisayo badlala indima ebalulekile ekulandiseni ukuhamba kwamanje. Ziyizakhi ezibalulekile kumadivayisi aqhamuka emijikelezweni elula emishini eyinkimbinkimbi. Izinto ezisetshenziselwa ukukhiqiza abavikeleke kakhulu zithinte kakhulu ukusebenza kwazo, ukuqina kanye nokusebenza kahle. Phakathi kwazo, ama-alloys we-iron-chromium-aluminium, ama-nickel-chromium alloys, kanye nama-alloys we-copper-nickel athakazelisa kakhulu ngenxa yezakhiwo zazo ezihlukile.
Kungani ama-alloys adlala indima ebalulekile ekulweni nokukhiqiza
I-Alloys yimixube yezinto ezimbili noma ngaphezulu, okungenani eyodwa yazo eyinsimbi. Zizokwengeza ukuthuthukisa izakhiwo ezithile ezinjengamandla, ukumelana nokugqwala kanye nokuqina okushisayo. Ngezicelo zokuphikisana, ukukhetha kwa-Alloy kuthinta i-coeffleent engafanele, ukuqina kanye nokusebenza okuphelele komphikisi.
Yini izakhiwo ezibalulekile ze-alloys ezisetshenziswayo
(1) Ukumelana: Umsebenzi oyinhloko wokuphikisana ukuhlinzeka ngokumelana nokugeleza kwamanje. Ukumelana kwe-alloy kuyisici esibalulekile ekunqumeni ukusebenza kwayo ekusebenzeni lo msebenzi. 2.
(2) Ukushisa okuhlanganisiwe: Le mpahla ikhombisa ukuthi ukumelana nokuphikiswa okuhlukahlukene okuhlukahluka ngokushisa. Ukumelana kudinga i-coeffient ephansi yokushisa yokumelana ukuze kuqinisekiswe ukusebenza okuzinzile ngaphezulu kwamazinga okushisa ahlukahlukene.
(3) Ukumelana nokugqwala: Ukumelana kuvame ukuvezwa ezindaweni ezinokhahlo. Ama-alloys amelana ne-oxidation kanye nokugqwala agricidence ukulondolozela impilo nokwethenjwa komphikisi.
(4) Amandla okwenziwa ngomshini: Ukumelana kumele kubekezelele ukucindezelwa ngokomzimba kanye nokuhamba ngebhayisikile. Ama-alloys anamandla aphezulu wemishini angamelana nalezi zimo ngaphandle kokuwohloka.
(5) Ukuqina okushisayo: amandla we-alloy ukuze alondoloze izakhiwo zawo emazingeni okushisa aphakeme asemqoka, ikakhulukazi ezinhlelweni zamandla aphezulu.
I-Iron Chromium Aluminium Alloy - Ukwakheka Nezakhiwo:
I-Iron-Chromium-Aluminium Alloys(I-FCRAL) yaziwa ngokumelana kwayo okuhle kwe-oxidation kanye nokuqina okushisa okuphezulu. Ngokuvamile kwakhiwa nge-iron, chromium ne-aluminium, lezi ze-alloys azihlali kangako emazingeni okushisa afinyelela ku-1400 ° C (2550 ° F).
Izicelo ku-Resistors:
I-Iron-Chromium-Aluminium Alloys isetshenziswa kabanzi kubameli bokushisa okuphezulu, ikakhulukazi kuzinhlelo zokusebenza ezilandelayo:
- Izinto zokushisa: Ama-alloy e-aluminium we-iron i-aluminium asetshenziswa kakhulu njengezinto zokushisa ezintweni zezimboni namahhavini ngenxa yokukwazi ukubhekana nobuqotho obuphakeme emazingeni okushisa aphezulu.
- Ukumelana Namandla: Lezi ze-alloys nazo zisetshenziswa kubameli bamandla abadinga ukuqina okuphezulu nokuqina kwe-oxidation.
- Izicelo zezimoto: kuma-elekthronikhi wezimoto, ama-alloys we-FECral asetshenziswa ngokumelana nale ndawo esebenza ezindaweni eziphakeme zokushisa, njengezinhlelo zokuqeda amandla.
I-Nickel-Chromium Alloys - Ukwakheka Nezakhiwo:
Ama-alloys we-nickel-chromium (NICR) angenye indlela ethandwayo yezicelo zokuphikisa. Lezi ze-alloys zivame ukwakhiwa nge-nickel ne-chromium, iphesenti layo lincike ezicini ezifunayo.Ama-nicr alloysbaziwa ngokumelana kwabo okuhle, ukusebenza okuphezulu kokushisa nokuphikiswa kokugqwala.
I-Nichrome Alloys isetshenziswa kakhulu:
- Ukumelana neFilimu: Lokhu kumelana nalokhu kusetshenziswa kuzinhlelo zokusebenza lapho ukunemba kubaluleke kakhulu futhi lapho i-Nicr Alloy ihlinzeka ngokuqina okudingekayo kanye nokushisa okuphansi okuphansi.
- Ukuphikiswa kweWirewound
- Izicelo eziphezulu zokushisa: ezifanayo ne-Ferrochromium-Aluminium Alloys, ama-nickel-chromium alloys alungele izindawo eziphakeme zokushisa, ezenza zilungele izinhlelo zokusebenza zezimboni nezama-aerospace.
I-Copper-Nickel Alloys - Ukwakheka Nezakhiwo
Ama-alloys we-Copper-Nickel (Cuni) ayaziwa ngokuvuselelwa kwawo kukagesi okuhle nokuphikiswa kokugqwala. Lama-alloys ngokuvamile aqukethe ithusi ne-nickel, enezici ezithile ezitholwe ngokuhlukahluka kokuqukethwe kwe-nickel. I-Cuni Alloys ibaluleke kakhulu ngekhono labo lokugcina ukusebenza kwasolwandle nakwezinye izindawo ezilonakalisayo.
I-Copper-Nickel Alloys isetshenziswa ezinhlelweni ezahlukahlukene zokuphikisa, kufaka phakathi:
- Ukuphikiswa okunembile: Ngenxa yokuvuka kwabo okuhle nokuqina,I-Cuni Alloyszivame ukusetshenziselwa ukumelana ngokunemba ekulinganiseni nasekulawulweni kwezicelo.
- Izicelo zasolwandle: Ukumelana nokugqwala kwe-Orloys ye-Cuni kubenza balungele abaphikisayo abasetshenziswa ezindaweni zasolwandle lapho kuvezwa khona amanzi kasawoti.
- Izicelo zokushisa eziphansi: Ama-Alloys we-Copper-Nickel enza kahle ezindaweni ze-crygenic, ukuzenza zilungele izinhlelo zokushisa eziphansi.
I-Fecral, i-nichrome, kanye ne-copper-nickel alloys bonke banezakhiwo ezihlukile ezizenza zilungele izinhlelo ezahlukahlukene.
- I-Iron-Chromium-Aluminium Alloys yenza kahle ezindaweni ezisezingeni eliphakeme futhi zilungele kahle izinto zokushisa kanye nokusakazwa kwamandla.
- I-Nickel-Chromium Alloys inikeza ukuqina okuhle nokuqina kokugqwala futhi ilungele amafilimu kanye nokumelana nokuwayiwa.
- Ama-Alloys weCopper-Nickel ayaziwa ngokuvuka kwawo okuphezulu nokumelana nokugqwala futhi afanelekele kahle ukumelana nokunemba kanye nezicelo zasolwandle.
