Munyika yesainzi yezvinhu uye mainjiniya emagetsi, mubvunzo wekuti nichrome ndiyo dhayagiramu yemagetsi yakanaka here kana kuti yakaipa wagara uchinetsa vaongorori, mainjiniya, nenyanzvi dzemuindasitiri. Sekambani inotungamira mukugadzira ma alloys emagetsi, Tankii aripo kuti ajekese nyaya iyi yakaoma.

Nichrome, chiumbwa chakagadzirwa ne nickel ne chromium, chine hunhu hwakasiyana hwemagetsi. Pakutanga, kana tichienzanisa nesimbi dzinofambisa magetsi zvakanyanya semhangura kana sirivha, nichrome inogona kuita seconductor isina kunaka. Semuenzaniso, mhangura ine conductivity yemagetsi inosvika 59.6×10^6 S/m pa20 °C, nepo conductivity yesirivha iri 63×10^6 S/m. Kusiyana neizvi, nichrome ine conductivity yakaderera zvikuru, inowanzova pakati pe1.0×10^6 - 1.1×10^6 S/m. Musiyano uyu mukuru mu conductivity values ​​unogona kuita kuti munhu anyore nichrome se conductor "yakaipa".

Zvisinei, nyaya iyi haigumiri ipapo. Kufambiswa kwemagetsi kwakaderera kwe nichrome chinhu chinodiwa mumabasa mazhinji. Imwe yenzira dzinonyanya kushandiswa dze nichrome ndeyekudziisa zvinhu. Kana magetsi emagetsi achipinda nemu conductor, zvichienderana nemutemo waJoule (P = I²R, uko P iri simba rakabviswa, I iri simba, uye R iri simba), simba rinobviswa muchimiro chekupisa. Kuramba kwakanyanya kwe Nichrome zvichienzaniswa nema conductor akanaka semhangura zvinoreva kuti kune magetsi akapihwa, kupisa kwakawanda kunogadzirwa muwaya ye nichromeIzvi zvinoita kuti ive chinhu chakanakira kushandiswa senge matoaster, maheater emagetsi, uye maovheni emaindasitiri.

Uyezve, nichrome ine simba guru rekudzivirira kuoxidation uye ngura. Munzvimbo dzine tembiricha yepamusoro uko zvinhu zvinodziya zvinowanzo shandiswa, kugona kwayo kudzivirira kuora kwakakosha. Kunyange zvazvo kuderera kwayo mukufambisa zvinhu kungave dambudziko mukushandiswa uko kuderedza kusimba kwakakosha, senge mumitsetse yemagetsi, inova mukana wakakura mukushandiswa kwekudziyisa.

Kubva pamaonero e[Zita reKambani], kunzwisisa hunhu hwenichrome kwakakosha pakugadzirwa kwezvigadzirwa zvedu uye hunyanzvi. Tinogadzira zvinhu zvakasiyana-siyana zvinodziya zvinobva munichrome zvinoshandiswa mumaindasitiri akasiyana-siyana. Chikwata chedu cheR & D chiri kushanda nguva dzose pakugadzirisa kuumbwa kwenichrome alloys kuti zviwedzere kushanda zvakanaka. Semuenzaniso, nekugadzirisa chiyero chenickel nechromium, tinogona kugadzirisa resistance yemagetsi uye hunhu hwemakanika hwealloy kuti ienderane zviri nani nezvinodiwa zvekushandiswa.

Mukupedzisa, kurongwa kwe nichrome semuchina wemagetsi wakanaka kana wakaipa kunoenderana zvachose nekushandiswa kwayo. Munyaya yekufambisa magetsi kuti awane simba - kutumirwa zvakanaka, haishande sedzimwe simbi. Asi munhau yekupisa magetsi, hunhu hwayo hunoita kuti ive chinhu chisingatsiviwi. Sezvo tekinoroji ichiramba ichichinja, tinofara kutsvaga nzira itsva dzekushandisa nichrome nedzimwe alloys dzekupisa kuti zvigutse zvinodiwa nemaindasitiri akasiyana-siyana. Ingave iri kugadzira mhinduro dzekupisa dzinoshanda zvakanyanya dzemagetsi emhuri kana zvinhu zvekupisa zvinoshanda zvakanyanya zvemaindasitiri, hunhu hwakasiyana hwenichromeicharamba ichiita basa rakakosha mukugadzira ramangwana rekushandiswa kwemagetsi ekudziyisa.
