Mumagetsi, zvinopikisa zvinoita basa rakakosha mukudzora kuyerera kwezvino. Izvo zvakakosha zvikamu mumidziyo kubva kune akareruka masekete kusvika kune yakaoma michina. Izvo zvinhu zvinoshandiswa kugadzira resistors zvinokanganisa zvakanyanya kuita kwavo, kusimba uye kugona. Pakati pazvo, iron-chromium-aluminium alloys, nickel-chromium alloys, uye copper-nickel alloys ndeyekufarira kukuru nekuda kwehumwe hutano hwavo.
Nei alloys achiita basa rakakosha mukugadzira resistor
Alloys musanganiswa wezvinhu zviviri kana kupfuura, imwe yacho isimbi. Iwo akagadzirwa kuti awedzere chaiwo zvivakwa zvakaita sesimba, corrosion resistance uye kugadzikana kwemafuta. Mune resistor applications, sarudzo yealloy inokanganisa tembiricha coefficient, kugadzikana uye kuita kwese kweanopikisa.
Ndeapi akakosha zvimiro zvealloys anoshandiswa mune resistors
(1) Resistance: Basa rekutanga remudziviriri nderokupa kuramba kuyerera kwezvino. The resistivity of the alloy chinhu chinokosha pakuona kushanda kwayo mukuita basa iri. 2.
(2) Temperature Coefficient: Ichi chivakwa chinoratidza kuti kupikisa kwechinhu kwakasiyana sei nekupisa. Resistors inoda yakaderera tembiricha coefficient yekupokana kuti ive nechokwadi chekushanda kwakagadzikana pamusoro pemhando dzakasiyana dzetembiricha.
(3) Corrosion Resistance: Zvidziviriri zvinowanzoonekwa munzvimbo dzakaoma. Alloys anoramba oxidation uye corrosion akakosha kuchengetedza hupenyu uye kuvimbika kweanopikisa.
(4) Mechanical Strength: Vadzivisi vanofanira kumira kushushikana kwemuviri uye kupisa bhasikoro. Alloys ane high mechanical simba anogona kumira aya mamiriro pasina kuora.
(5) Thermal Kugadzikana: Kugona kwealloy kuchengetedza zvimiro zvayo patembiricha yakakwira yakakosha, kunyanya mumashandisirwo emagetsi.
Iron Chromium Aluminium Alloy - Kuumbwa uye Zvivakwa:
Iron-chromium-aluminium alloys(FeCrAl) vanozivikanwa nekunaka kwavo oxidation kuramba uye kugadzikana kwepamusoro-tembiricha. Kazhinji inoumbwa nesimbi, chromium nealuminium, aya alloys haadzikisire zvakanyanya patembiricha inosvika 1400 ° C (2550 ° F).
Zvikumbiro muResistors:
Iron-chromium-aluminium alloys anoshandiswa zvakanyanya mukupisa-tembiricha resistors, kunyanya mune anotevera maapplication:
- Heating Elements: Iron Chromium Aluminium alloys anowanzo shandiswa sezvinhu zvekudziya mumaindasitiri echoto uye ovheni nekuda kwekugona kwavo kuchengetedza kuvimbika kwechimiro pakupisa kwakanyanya.
-Masimba ekupikisa: Aya maalloys anoshandiswawo mumagetsi anopikisa anoda kugadzikana kwemafuta uye oxidation kuramba.
- Zvishandiso zveMotokari: Mumagetsi emotokari, maFeCrAl alloys anoshandiswa mumaresitorendi anoshanda munzvimbo dzakanyanya kupisa, senge masisitimu emhepo.
Nickel-Chromium Alloys - Kuumbwa uye Zvivakwa:
Nickel-chromium (NiCr) alloys ndiyo imwe sarudzo yakakurumbira yekupikisa maapplication. Aya ma alloys anowanzo kuumbwa nickel uye chromium, iyo muzana inotsamira pane inodiwa maitiro.NiCr alloysvanozivikanwa nekuramba kwavo kwakanakisa, tembiricha yepamusoro uye kusagadzikana kwekuora.
Nichrome alloys anowanzoshandiswa:
- Firimu Resistors: Aya anopikisa anoshandiswa mumashandisirwo uko kurongeka kwakakosha uye uko NiCr alloy inopa kugadzikana kunodiwa uye yakaderera tembiricha coefficient.
- Wirewound Resistors: Mune wirewound resistors, Nichrome waya inowanzoshandiswa nekuda kwekupokana kwayo kwakanyanya uye kugona kutsungirira kupisa bhasikoro.
- Yakakwira Tembiricha Zvishandiso: Zvakafanana neferrochromium-aluminium alloys, nickel-chromium alloys akakodzera kune yakanyanya tembiricha nharaunda, ichiita kuti ive yakanaka kune maindasitiri uye aerospace application.
Copper-nickel alloys - kuumbwa uye zvivakwa
Copper-nickel (CuNi) alloys anozivikanwa neakanakisa emagetsi conductivity uye kusaita ngura. Aya alloys anowanzo aine mhangura uye nickel, ane chaiwo zvivakwa zvinowanikwa nekusiyanisa nickel yemukati. CuNi alloys anonyanya kukosheswa nekugona kwavo kuchengetedza kuita mumakungwa uye dzimwe nzvimbo dzinoparadza.
Copper-nickel alloys anoshandiswa mumhando dzakasiyana dzeresistor application, kusanganisira:
- Precision Resistors: Nekuda kwekuita kwavo kwakanaka uye kugadzikana,CuNi alloysanowanzo kushandiswa kune chaiyo resistors mukuyera uye kutonga maapplication.
- Marine application: Iyo corrosion resistance yeCuNi alloys inoita kuti ive yakakodzera kune zvinopikisa zvinoshandiswa munzvimbo dzemugungwa uko kuratidzwa nemvura yemunyu kunogona kukuvadza.
- Yakaderera Tembiricha Zvishandiso: Copper-nickel alloys inoita zvakanaka munzvimbo dze cryogenic, ichiita kuti ive yakakodzera kune yakaderera tembiricha yekushandisa.
FeCrAl, nichrome, uye copper-nickel alloys zvese zvine zvimiro zvakasiyana zvinoita kuti zvikodzere kune zvakasiyana-siyana zvekushandisa.
-Iron-chromium-aluminium alloys inoita zvakanaka munzvimbo dzepamusoro-tembiricha uye yakanyatsokodzera kupisa zvinhu uye simba rekudzivirira.
-Nickel-chromium alloys inopa kugadzikana kwakanyanya uye kusagadzikana kwemarara uye akakodzera firimu uye wirewound resistors.
- Copper-nickel alloys inozivikanwa nekukwira kwayo uye corrosion resistance uye yakanyatsokodzera maprecision resistors uye marine application.
