Tungsten Carbide-Nickel ke Magnetic kapa ha e na makenete?

Tungsten carbide, eo hape e bitsoang cemented carbide, e entsoe ka tungsten carbide powder le binder powder. Phofo e kopanyang e ka ba phofo ea cobalt kapa phofo ea nickel. Ha re sebelisa phofo ea cobalt e le setlamo ho etsa lihlahisoa tsa tungsten carbide, re tla ba le tlhahlobo ea cobalt magnetic ho hlahloba palo ea cobalt ka tungsten carbide. Kahoo ke 'nete hore tungsten carbide-cobalt ke makenete. Leha ho le joalo, tungsten carbide-nickel ha e na matla a khoheli.

U ka 'na ua ikutloa hore ha ho kholoehe qalong. Empa ke nnete. Tungsten carbide-nickel ke mofuta oa thepa e seng ea makenete e nang le tšusumetso e ntle. Sehloohong sena, ke rata ho u hlalosetsa sena.

Joalo ka litšepe tse hloekisitsoeng, cobalt le nickel li na le matla a khoheli. Ka mor'a ho kopanya, ho hatella le ho sintering le tungsten carbide powder, tungsten carbide-cobalt e ntse e le magnetic, empa tungsten carbide-nickel ha e joalo. Sena se bakoa ke hore liathomo tsa tungsten li kena ka lesela la nickel ebe li fetola li-electron spins tsa nickel. Ebe li-electron spins tsa tungsten carbide li ka hlakola. Kahoo, tungsten carbide-nickel e ke ke ea hoheloa ke makenete. Bophelong ba rona ba letsatsi le letsatsi, tšepe e sa hloekang le eona e sebetsa molao-motheo ona.

electron spin ke eng? Electron spin ke e 'ngoe ea likarolo tse tharo tsa tlhaho tsa lielektrone. Lintho tse ling tse peli ke boima le tefiso ea elektronike.

Lintho tse ngata li entsoe ka limolek'hule, limolek'hule li entsoe ka liathomo, 'me liathomo li entsoe ka li-nuclei le lielektrone. Liathomong, lielektrone li lula li bilika le ho potoloha khubu. Metsamao ena ea li-electrone e ka etsa magnetism. Linthong tse ling, li-electrone li tsamaea ka mahlakoreng a sa tšoaneng, 'me liphello tsa makenete li ka tima e le hore lintho tsena li se ke tsa khoheli tlas'a maemo a tloaelehileng.

Leha ho le joalo, lintho tse ling tsa ferromagnetic tse kang tšepe, cobalt, nickel kapa ferrite li fapane. Li-spins tsa tsona tsa elektrone li ka hlophisoa ka mefuta e nyane ho etsa sebaka sa makenete. Ke ka lebaka leo cobalt le nickel tse hloekisitsoeng li leng matla 'me li ka hoheloa ke makenete.

Ho tungsten carbide-nickel, liathomo tsa tungsten li ama li-electron spins tsa nickel, kahoo tungsten carbide-nickel ha e sa le makenete.

Ho latela liphetho tse ngata tsa mahlale, tungsten carbide-nickel e na le khanyetso e phahameng ea kutu le khanyetso ea oxidation ho feta tungsten carbide-cobalt. Ha u ntse u etsa sintering, nickel e ka etsa mokelikeli habonolo, e ka fanang ka bokhoni bo betere ba metsi holim'a tungsten carbide. Ho feta moo, nickel e theko e tlase ho feta cobalt.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
