Tungsten Carbide-Nickel Is Magnetic kana Isiri-Magineti?
Tungsten Carbide-Nickel Is Magnetic kana Isiri-Magineti?
Tungsten carbide, inonziwo cemented carbide, inoumbwa ne tungsten carbide poda uye binder poda. Iyo binder powder inogona kuva cobalt powder kana nickel powder. Patinenge tichishandisa cobalt poda sechisungirirwa mukugadzira tungsten carbide zvigadzirwa, tichava necobalt magnetic test yekuongorora huwandu hwecobalt mu tungsten carbide. Saka ndezvechokwadi kuti tungsten carbide-cobalt ine magineti. Zvisinei, tungsten carbide-nickel haisi magnetic.
Unogona kunzwa kuti hazvidaviriki pakutanga. Asi ichokwadi. Tungsten carbide-nickel imhando yeisina-magineti zvinhu zvine kunaka kupikisa kuramba. Muchinyorwa chino, ndinoda kutsanangura izvi kwauri.
Sesimbi dzakacheneswa, cobalt uye nickel zvine magineti. Mushure mekusanganisa, kudzvanya, uye kunyura ne tungsten carbide poda, iyo tungsten carbide-cobalt ichiri magineti, asi tungsten carbide-nickel haisi. Izvi zvinodaro nekuti maatomu etungsten anopinda muura re nickel ochinja maerekitironi spins enickel. Ipapo ma electron spins e tungsten carbide anogona kukanzura. Saka, tungsten carbide-nickel haigoni kukwezvwa nemagineti. Muhupenyu hwedu hwezuva nezuva, simbi isina tsvina inoshandisawo musimboti uyu.
Chii chinonzi electron spin? Electron spin chimwe chezvinhu zvitatu zvakasikwa zvemaerekitironi. Mimwe miviri miviri ndiyo misa uye kuchaja kweerekitironi.
Zvizhinji zvezvinhu zvinoumbwa nemamorekuru, mamorekuru anoumbwa nemaatomu, uye maatomu anoumbwa nuclei nemaerekitironi. Mumaatomu, maerekitironi anogara achitenderera nekutenderera kutenderera nucleus. Aya mafambiro emaerekitironi anogona kugadzira magineti. Mune zvimwe zvinhu, maerekitironi anofamba nenzira dzakasiyana, uye magineti anogona kukanzura kuitira kuti zvinhu izvi zvisave magineti mumamiriro ezvinhu akajairika.
Nekudaro, zvimwe ferromagnetic zvinhu zvakaita sesimbi, cobalt, nickel, kana ferrite zvakasiyana. Ma electron spins avo anogona kurongwa mudiki diki kuti aite magnetic domain. Ichi ndicho chikonzero cobalt yakacheneswa uye nickel zvine magineti uye inogona kukwezvwa nemagineti.
Mu tungsten carbide-nickel, maatomu etungsten anokanganisa ma electron spins e nickel, saka tungsten carbide-nickel haisisiri magineti.
Zvinoenderana nezvakawanda zvesainzi mhedzisiro, tungsten carbide-nickel ine yakakwira corrosion resistance uye oxidation kuramba kupfuura tungsten carbide-cobalt. Mukuita sintering, iyo nickel inogona kuumba chikamu chemvura zviri nyore, iyo inogona kupa zvirinani kunyorova kugona pane tungsten carbide nzvimbo. Uyezve, nickel yakaderera mumutengo pane cobalt.
Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
