Tungsten Carbide-Nickel Ndi Maginito Kapena Osakhala Maginito?

Tungsten carbide, yomwe imatchedwanso cemented carbide, imapangidwa ndi tungsten carbide powder ndi binder powder. Ufa wa binder ukhoza kukhala ufa wa cobalt kapena ufa wa nickel. Tikamagwiritsa ntchito ufa wa cobalt ngati chomangira popanga zinthu za tungsten carbide, tidzakhala ndi mayeso a maginito a cobalt kuti tiwone kuchuluka kwa cobalt mu tungsten carbide. Chifukwa chake ndizotsimikizika kuti tungsten carbide-cobalt ndi maginito. Komabe, tungsten carbide-nickel si maginito.

Mungaone kuti n’zosakhulupilika poyamba. Koma ndi zoona. Tungsten carbide-nickel ndi mtundu wazinthu zopanda maginito zomwe zimakana kukana. M'nkhaniyi, ndikufuna kukufotokozerani izi.

Monga zitsulo zoyeretsedwa, cobalt ndi faifi tambala ndi maginito. Pambuyo kusakaniza, kukanikiza, ndi sintering ndi tungsten carbide ufa, tungsten carbide-cobalt akadali maginito, koma tungsten carbide-nickel si. Izi zili choncho chifukwa maatomu a tungsten amalowa muzitsulo za nickel ndikusintha ma electron spins a nickel. Ndiye ma electron spins a tungsten carbide akhoza kuchotsedwa. Choncho, tungsten carbide-nickel sangathe kukopeka ndi maginito. M’moyo wathu watsiku ndi tsiku, zitsulo zosapanga dzimbiri zimagwiritsanso ntchito mfundo imeneyi.

Kodi electron spin? Electron spin ndi imodzi mwazinthu zitatu zomwe ma elekitironi amabadwa nazo. Zina ziwiri ndizo misa ndi mphamvu ya electron.

Zinthu zambiri zimapangidwa ndi mamolekyu, mamolekyu amapangidwa ndi maatomu, ndipo maatomu amapangidwa ndi ma nuclei ndi ma electron. Mu maatomu, ma elekitironi amangozungulira ndi kuzungulira phata. Kusuntha kwa ma elekitironi uku kumatha kupanga maginito. Muzinthu zina, ma elekitironi amasuntha mbali zosiyanasiyana, ndipo mphamvu ya maginito imatha kuzima kuti zinthuzi zisawonongeke nthawi zonse.

Komabe, zinthu zina za ferromagnetic monga chitsulo, cobalt, nickel, kapena ferrite ndizosiyana. Ma electron spins awo amatha kukonzedwa pang'ono kuti apange maginito. Ichi ndichifukwa chake cobalt oyeretsedwa ndi faifi tambala ndi maginito ndipo akhoza kukopeka ndi maginito.

Mu tungsten carbide-nickel, ma atomu a tungsten amakhudza ma electron spins a nickel, kotero tungsten carbide-nickel simaginitonso.

Malinga ndi zotsatira zambiri zasayansi, tungsten carbide-nickel imakhala ndi kukana kwa dzimbiri komanso kukana kwa okosijeni kuposa tungsten carbide-cobalt. Mu sintering, faifi tambala amatha kupanga gawo lamadzimadzi mosavuta, lomwe limatha kupereka kuthekera konyowa bwino pamawonekedwe a tungsten carbide. Kuphatikiza apo, nickel ndi yotsika mtengo kuposa cobalt.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
