Alnico Igwe Ọdụdọ

Nkọwa dị mkpirikpi:

Alnico magnetik bụ ụdị magnetik siri ike mejuputara na alloys nke Aluminom, Nickel, na Cobalt. A na-arụpụta ya site na nkedo ma ọ bụ usoro ịmegharị ihe. Tupu e mepụta magnetik ụwa na-adịghị ahụkebe na 1970, Alnico magnet bụ ụdị magnet na-adịgide adịgide kachasị ike ma jiri ya mee ihe.

N'oge a, n'ọtụtụ ngwa Alnico ejiri Neodymium ma ọ bụ Samarium Cobalt magnet dochie ya. Otú ọ dị, ihe onwunwe ya dị ka nkwụsi ike okpomọkụ na oke okpomọkụ na-arụ ọrụ na-eme ka Alnico magnetik dị mkpa na ụfọdụ ahịa ngwa.

Uru

1. Igwe ndọta dị elu. Residual induction bụ elu 11000 Gauss fọrọ nke nta ka yiri Sm2Co17 magnet, na mgbe ahụ ọ nwere ike na-emepụta elu magnetik gburugburu.

2. Ọnọdụ okpomọkụ dị elu. Okpomọkụ kachasị arụ ọrụ ya nwere ike ịdị elu ruo 550⁰C.

3. Nkwụsi ike dị elu: Alnico magnet nwere ọnụọgụ okpomọkụ kachasị mma nke ihe ọ bụla magnetik. Ekwesịrị ka a na-ahụta magnetik Alnico dị ka nhọrọ kacha mma na ngwa oke okpomọkụ.

4. Magburu onwe corrosion eguzogide. Ihe ndọta Alnico adịghị adịkarị mfe corrosion ma enwere ike iji ya na-enweghị nchebe elu ọ bụla

Ọdịmma

1. Dị mfe demagnetize: Ya kacha ala coercive ike Hcb bụ ala karịa 2 kOe na mgbe ahụ ọ dị mfe demagnetize na ụfọdụ ala demagnetizing ubi, ọbụna na-adịghị edozi ya na-elekọta.

2. Ike na kenkuwa. Ọ na-esiri ike ịkụcha na mgbawa.

Ihe ndị a ga-atụle maka ngwa

1. Dị ka coercivity nke Alnico magnets dị ala, oke nke ogologo na dayameta kwesịrị ịbụ 5: 1 ma ọ bụ karịa ka ị nweta ezigbo ọrụ nke Alnico.

2. Dị ka Alnico magnetik na-adị mfe demagnetized site n'akpachapụghị anya njikwa, a na-atụ aro na-eme ka magnetizing mgbe mgbakọ.

3. Alnico magnetik na-enye nkwụsi ike okpomọkụ pụtara ìhè. Nsonaazụ sitere na ndọta Alnico na-adịgasị iche ma ọ dịkarịa ala na mgbanwe okpomọkụ, na-eme ka ọ bụrụ nhọrọ dị mma maka ngwa nwere mmetụta okpomọkụ, dị ka ọgwụ na ndị agha.
