Tungsten Carbide-Nickel Yog Sib Nqus lossis Tsis-Magnetic?

Tungsten carbide, tseem hu ua cemented carbide, yog tsim los ntawm tungsten carbide hmoov thiab binder hmoov. Cov hmoov nplej tuaj yeem yog cobalt hmoov lossis npib tsib xee hmoov. Thaum peb siv cov hmoov cobalt los ua cov ntawv khi hauv kev tsim cov khoom siv tungsten carbide, peb yuav muaj kev sim cobalt sib nqus los tshuaj xyuas cov nyiaj cobalt hauv tungsten carbide. Yog li nws muaj tseeb tias tungsten carbide-cobalt yog hlau nplaum. Txawm li cas los xij, tungsten carbide-nickel tsis yog hlau nplaum.

Tej zaum koj yuav xav tias nws yog qhov tsis ntseeg thaum pib. Tab sis nws muaj tseeb. Tungsten carbide-nickel yog ib yam khoom uas tsis muaj hlau nplaum uas muaj kev cuam tshuam zoo. Hauv tsab xov xwm no, kuv xav piav qhia qhov no rau koj.

Raws li cov hlau purified, cobalt thiab nickel yog hlau nplaum. Tom qab sib tov, nias, thiab sintering nrog tungsten carbide hmoov, tungsten carbide-cobalt tseem sib nqus, tab sis tungsten carbide-nickel tsis yog. Qhov no yog vim hais tias cov tungsten atoms nkag mus rau hauv lub lattice ntawm npib tsib xee thiab hloov cov electron spin ntawm nickel. Tom qab ntawd cov electron spin ntawm tungsten carbide tuaj yeem tshem tawm. Yog li, tungsten carbide-nickel tsis tuaj yeem nyiam los ntawm cov hlau nplaum. Hauv peb lub neej niaj hnub, cov hlau tsis muaj steel kuj siv txoj cai no.

Dab tsi yog electron spin? Electron spin yog ib qho ntawm peb lub hauv paus ntawm cov khoom siv hluav taws xob. Lwm ob lub zog yog qhov loj thiab nqi ntawm cov electron.

Cov tshuaj feem ntau yog tsim los ntawm molecules, molecules yog tsim los ntawm atoms, thiab atoms yog tsim los ntawm nuclei thiab electrons. Nyob rau hauv lub atoms, electrons tas li spinning thiab rotating ib ncig ntawm lub nucleus. Cov kev txav ntawm electrons tuaj yeem tsim cov hlau nplaum. Hauv qee yam khoom, cov khoom siv hluav taws xob txav mus rau qhov sib txawv, thiab cov teebmeem sib nqus tuaj yeem tshem tawm kom cov tshuaj no tsis sib nqus nyob rau hauv ib txwm muaj.

Txawm li cas los xij, qee cov tshuaj ferromagnetic xws li hlau, cobalt, npib tsib xee, lossis ferrite txawv. Lawv cov khoom siv hluav taws xob tuaj yeem raug teeb tsa hauv ib qho me me los ua ib qho chaw sib nqus. Qhov no yog vim li cas purified cobalt thiab npib tsib xee yog sib nqus thiab tuaj yeem nyiam los ntawm cov hlau nplaum.

Hauv tungsten carbide-nickel, tungsten atoms cuam tshuam rau electron spin ntawm nickel, yog li tungsten carbide-nickel tsis sib nqus ntxiv lawm.

Raws li ntau qhov kev tshawb fawb, tungsten carbide-nickel muaj ntau dua corrosion kuj thiab oxidation tsis kam tshaj tungsten carbide-cobalt. Hauv sintering, cov npib tsib xee tuaj yeem tsim cov theem ua kua tau yooj yim, uas tuaj yeem muab kev muaj peev xwm ntub dej zoo dua ntawm tungsten carbide nto. Dab tsi ntxiv, npib tsib xee qis dua tus nqi tshaj cobalt.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
