Munyika yesainzi yezvigadzirwa uye engineering yemagetsi, mubvunzo wekuti nichrome yakanaka here kana yakaipa conductor yemagetsi yakagara ichishamisa vaongorori, mainjiniya, uye nyanzvi dzeindasitiri zvakafanana. Sekambani inotungamira mumunda wemagetsi ekudziya alloys, Tankii iri pano kuzojekesa nyaya iyi yakaoma.

Nichrome, alloy inonyanya kuumbwa nickel uye chromium, ine yakasarudzika magetsi emagetsi. Pakutanga kuona, kana ichienzaniswa nesimbi dzinoita semhangura kana sirivheri, nichrome inogona kuita senge murombo conductor. Mhangura, semuenzaniso, ine magetsi ekutenderera kwe59.6 × 10 ^ 6 S / m pa20 ° C, nepo sirivheri conductivity inenge 63 × 10 ^ 6 S / m. Kusiyana neizvi, nichrome ine yakaderera conductivity, kazhinji muhuwandu hwe1.0 × 10 ^ 6 - 1.1 × 10 ^ 6 S/m. Uyu mutsauko wakakosha muhunhu hwekuita unogona kutungamira munhu kuti atore nichrome se "yakaipa" conductor.

Zvisinei, nyaya yacho haigumiri ipapo. Iyo yakaderera magetsi conductivity ye nichrome ichokwadi chivakwa chinodiwa mune akawanda maapplication. Imwe yeinonyanya kushandiswa ye nichrome iri mukupisa zvinhu. Kana magetsi achipfuura nemu conductor, maererano nemutemo waJoule (P = I²R, apo P isimba rakabviswa, ini ndiri ikozvino, uye R ndiyo inopikisa), simba rinobviswa nenzira yekupisa. Kuramba kweNichrome kwepamusoro kana kuchienzaniswa nemakondukita akanaka semhangura zvinoreva kuti kune yakapihwa ikozvino, kupisa kwakawanda kunogadzirwa munichrome waya. Izvi zvinoita kuti ive chinhu chakakodzera chekushandisa senge toasters, maheater emagetsi, uye mabindu emaindasitiri.

Uyezve, nichrome zvakare ine yakanakisa kuramba kune oxidation uye ngura. Munzvimbo dzepamusoro-tembiricha umo kupisa zvinhu zvinowanzo shandiswa, kugona kuramba kudzikira kwakakosha. Kunyange iyo yakaderera conductivity ingave yekudzosera kumashure mumashandisirwo uko kuderedza kuramba kwakakosha, senge mumatambo ekufambisa magetsi, inova mukana wakasiyana mukupisa maapplication.

Kubva pamaonero e[Zita reKambani], kunzwisisa zvimiro zve nichrome kwakakosha pakukura kwechigadzirwa chedu uye hunyanzvi. Isu tinogadzira huwandu hwakawanda hwenichrome - yakavakirwa kupisa zvinhu zvinoshandiswa mumaindasitiri akasiyana. Chikwata chedu cheR & D chinogara chichishanda mukugadzirisa kuumbwa kwenichrome alloys kuti vawedzere kuita kwavo. Semuenzaniso, nekugadzirisa chiyero chenickel uye chromium, tinokwanisa kugadzirisa kupikisa kwemagetsi uye michina yealloy kuti ikwane zvirinani zvinodiwa zvekushandisa.

Mukupedzisa, kurongeka kwe nichrome seyakanaka kana yakaipa conductor yemagetsi inoenderana zvachose nemamiriro ekushandiswa kwayo. Munzvimbo yemagetsi conductivity kune simba - kufambisa kunobudirira, haisi kushanda semamwe masimbi. Asi mumunda wekudziya kwemagetsi, maitiro ayo anoita kuti ive chinhu chisingachinjiki. Sezvo tekinoroji iri kuramba ichishanduka, isu tinofara kutsvaga nzira nyowani dzekushandisa nichrome uye mamwe ekudziya alloys kusangana nekukura kuri kuda kwemaindasitiri akasiyana. Kungave kuri kuvandudza simba rakawanda - rinoshanda magetsi ekudziya edzimba kana akakwira - performance inodziya zvinhu zvemaindasitiri maitiro, yakasarudzika zvivakwanichromeicharamba ichiita basa rinokosha mukugadzirisa ramangwana rekushanda kwemagetsi ekupisa.
