Nigute twakwirinda kwangirika kwa magneti?

Ugereranije na ferrite nibindi bikoresho bya magneti bihoraho, magneti ya neodymium (NdFeB magnet) ifite magnetisme nziza kandi ni nabwo bukoreshwa cyane mubutaka budasanzwe.Ikoreshwa cyane muri elegitoroniki, imashini zikoresha ingufu, ibikoresho byubuvuzi, ibikinisho, gupakira, imashini zikoresha ibikoresho, ikirere nizindi nzego.Nyamara, magnesi ya neodymium (Magnets ya NdFeB) irashobora kwangirika cyane.Nigute twakwirinda kwangirika kwa magneti neodymium?Hariho uburyo rusange bukurikira:
1 、 Fosifati
Fosifatiya ni inzira ya chimique na electrochemic reaction kugirango ikore firime ya fosifate.Fosifati ifite intego zikurikira:
1. Kurinda icyuma fatizo kwangirika kurwego runaka.
2. Ikoreshwa nka primer mbere yo gushushanya kugirango irusheho gukomera no kwangirika kwa firime.
3. Ifite uruhare rwo kugabanya ubukana no gusiga amavuta mugihe gikonje gikora.
2 、 Amashanyarazi
Amashanyarazi ninzira yo gushiraho urwego ruto rwibindi byuma cyangwa ibishishwa hejuru yandi mabuye na electrolysis.Inzira ya electroplating ni inzira yo gukoresha electrolysis kugirango ihuze hejuru yicyuma cyangwa ibindi bikoresho kuri firime yicyuma, kugirango wirinde okiside yicyuma (nka ruswa), kunoza imyambarire, kwifata, kwerekana, kurwanya ruswa no kongera ingaruka nziza.
3 、 Amashanyarazi
Mubikorwa byumuriro wamashanyarazi, ibice byashizwemo bigenda byerekeza kuri electrode ihabanye namashanyarazi yabo, aribyo bita electrophorei.Tekinoroji yo gutandukanya ibice byashizwemo binyuze mumuvuduko utandukanye wibice byashizwe mumashanyarazi bita electrophoreis.Electrophoresis ni bumwe mu buhanga bwo kurwanya ruswa ikoreshwa cyane mu kuvura Nd-Fe-B hamwe na Nd-Fe-B ihoraho.Ipitingi ya electrophoreque ntabwo ifata neza gusa hejuru ya magneti, ariko kandi ifite ibiranga spray yumunyu, aside hamwe na alkali irwanya ruswa.
