Mumagetsi, ma resistors anoita basa rakakosha mukudzora kufamba kwemagetsi. Izvi zvinhu zvakakosha mumidziyo inotangira pamatunhu akareruka kusvika kumichina yakaoma. Zvinhu zvinoshandiswa kugadzira ma resistors zvinokanganisa zvikuru mashandiro azvo, kugara kwenguva refu uye kushanda zvakanaka. Pakati pazvo, ma alloys esimbi-chromium-aluminium, nickel-chromium alloys, uye copper-nickel alloys anonakidza zvikuru nekuda kwehunhu hwazvo hwakasiyana.
Nei ma alloys achiita basa rakakosha mukugadzira resistor
Ma alloys musanganiswa wezvinhu zviviri kana kupfuura, chimwe chazvo chiri simbi. Akagadzirwa kuti awedzere hunhu hwakadai sekusimba, kuramba ngura uye kugadzikana kwekupisa. Mukushandiswa kwe resistor, sarudzo ye alloy inokanganisa tembiricha coefficient, kugadzikana uye kushanda kwese kwe resistor.
Ndezvipi zvinhu zvakakosha zve alloys zvinoshandiswa mu resistors
(1) Kuramba: Basa guru remushonga wekudzivirira nderekupa simba rekudzivirira kuyerera kwemagetsi. Kuramba kwemushonga wesimbi chinhu chakakosha pakuona kushanda kwawo mukuita basa iri. 2.
(2) Kuenzana Kwekupisa: Hunhu uhwu hunoratidza kuti kuramba kwechinhu kunosiyana sei nekupisa. Zvinodzivirira zvinoda kuenzana kwekupisa kwakaderera kuti zvive nechokwadi chekuti zvinoshanda zvakanaka pakupisa kwakasiyana-siyana.
(3) Kuramba Kuora: Zvidziviriro zvinowanzo sangana nemamiriro ezvinhu akaomarara. Ma alloys anodzivirira oxidation uye ngura akakosha pakuchengetedza hupenyu uye kuvimbika kwechidziviriro.
(4) Simba reMichina: Zvinodzivirira zvinofanirwa kutsungirira kushushikana kwemuviri uye kupisa. Ma alloys ane simba guru remichina anogona kutsungirira mamiriro aya pasina kuora.
(5) Kugadzikana kweThermal: Kukwanisa kwe alloy kuchengetedza hunhu hwayo pakupisa kwakakwirira kwakakosha, kunyanya mukushandiswa kwesimba rakawanda.
Iron Chromium Aluminum Alloy - Muumbirwo uye Hunhu:
Zviumbwa zvesimbi-chromium-aluminium(FeCrAl) dzinozivikanwa nekudzivirira kwavo oxidation uye kugadzikana pakupisa kwakanyanya. Kazhinji dzinoumbwa nesimbi, chromium nealuminium, ma alloys aya haaori zvakanyanya pakupisa kusvika 1400°C (2550°F).
Mashandisirwo muResistors:
Ma alloys esimbi-chromium-aluminium anoshandiswa zvakanyanya mu resistors dzinopisa zvakanyanya, kunyanya muzvishandiso zvinotevera:
- Zvinhu Zvinodziya: Iron Chromium Alloys dzearuminiyamu dzinowanzo shandiswa sezvinhu zvinodziya mumaovheni emaindasitiri nemaovheni nekuda kwekugona kwadzo kuchengetedza chimiro chakasimba pakupisa kwakanyanya.
- Zvidziviriro zvemagetsi: Aya ma alloys anoshandiswawo muma resistor emagetsi anoda kugadzikana kwakanyanya kwekupisa uye kuramba kuoxidation.
- Mashandisirwo emotokari: Mumagetsi emotokari, FeCrAl alloys inoshandiswa muma resistors anoshanda munzvimbo dzinopisa zvakanyanya, senge masisitimu eutsi.
Nickel-Chromium Alloys - Kuumbwa uye Hunhu:
Ma alloys eNickel-chromium (NiCr) ndeimwe sarudzo yakakurumbira yekushandisa resistor. Ma alloys aya anowanzo kuve ne nickel ne chromium, chikamu chayo chinoenderana nehunhu hwaunoda.Ma alloys eNiCrvanozivikanwa nekugona kwavo kuramba kupisa, kushanda zvakanaka pakupisa kwakanyanya uye kuramba ngura.
Nichrome alloys dzinowanzoshandiswa:
- MaFirimu Anodzivisa: MaResistors aya anoshandiswa mumashandisirwo anoitwa zvinhu apo kunyatsoita zvinhu kwakakosha uye apo NiCr alloy inopa kugadzikana kunodiwa uye tembiricha yakaderera.
- Zvidziviriro zveWaya: Muzvidziviriro zvewaya, waya yeNichrome inowanzoshandiswa nekuda kwekudzivirira kwayo kwakanyanya uye kugona kwayo kutsungirira kupisa.
- Mashandisirwo eTembiricha Yakanyanya: Kufanana nema alloys eferrochromium-aluminium, nickel-chromium alloys akakodzera nzvimbo dzinopisa zvakanyanya, zvichiita kuti dzive dzakanakira maindasitiri uye mashandisirwo emuchadenga.
Ma alloys emhangura-nickel - maumbirwo uye hunhu
Ma alloys eCopper-nickel (CuNi) anozivikanwa nekugona kwawo kupinza magetsi zvakanaka uye kuramba ngura. Ma alloys aya anowanzo kuve ne copper ne nickel, ane hunhu hwakasiyana hunowanikwa nekusiyanisa huwandu hwe nickel. Ma alloys eCuNi anokosheswa zvikuru nekukwanisa kwawo kuchengetedza kushanda zvakanaka munzvimbo dzegungwa nedzimwe nzvimbo dzinopisa.
Masimbi emhangura-nickel alloys anoshandiswa mumhando dzakasiyana dzeresistor applications, dzinosanganisira:
- Zvinodzivirira Zvakakodzera: Nekuda kwekugona kwavo kufambisa zvinhu zvakanaka uye kugadzikana,Zvishongo zveCuNianoshandiswa zvakanyanya pakushandisa ma resistors ekuyera nekudzora.
- Mashandisirwo emvura: Kusagona ngura kweCuNi alloys kunoita kuti zvikodzere maresistor anoshandiswa munzvimbo dzegungwa uko kusangana nemvura ine munyu kunogona kukuvadza.
- Kushandiswa kweTembiricha Yakaderera: Ma alloys emhangura-nickel anoshanda zvakanaka munzvimbo dzine cryogenic, zvichiita kuti akwanise kushandiswa patembiricha yakaderera.
FeCrAl, nichrome, uye copper-nickel alloys zvese zvine hunhu hwakasiyana hunoita kuti zvikwanise kushandiswa zvakasiyana-siyana.
- Masimbi esimbi-chromium-aluminium anoshanda zvakanaka munzvimbo dzinopisa zvakanyanya uye akakodzera zvinhu zvinopisa uye zvinodzivirira simba.
- Ma alloys e nickel-chromium anopa kugadzikana kwakanaka uye kuramba ngura uye akakodzera ma resistors efirimu ne wirewound.
- Ma alloys emhangura-nickel anozivikanwa nekushanda kwawo nesimba uye kuramba ngura uye akakodzera kushandiswa nema resistors akarurama uye mashandisirwo emvura.
