Invention ntawm electroplated mus tas li hlau nplaum cov ntaub ntawv rau hluav taws xob cua sov raj
Kev tsim cov khoom siv hlau nplaum ruaj khov. Piv txwv li, cov ntaub ntawv 97108550.1 hais txog ib hom tshiab ntawm cov hlau chromium cobalt cov khoom siv hlau nplaum ruaj khov. Nws tswj cov ntsiab lus cobalt hauv cov hlau chromium cobalt cov khoom siv hlau nplaum ruaj khov rau 5.5 feem pua rau 6.8 feem pua; Tswj cov ntsiab lus chromium ntawm 30 feem pua thiab 35 feem pua; Cov ntsiab lus tooj liab yuav tsum tau tswj qis dua 4 feem pua. Cov hlau chromium cobalt cov khoom siv hlau nplaum ruaj khov tuaj yeem ntxiv qee cov kab ke xws li silicon thiab manganese thaum smelting. Cov ntaub ntawv 03111030.4 hais txog qhov muaj zog sib nqus teb ruaj khov hlau nplaum mechanism, uas cov khoom siv hlau nplaum ruaj khov yog tsim los ntawm 8-64 neodymium hlau boron ruaj khov hlau nplaum thaiv nrog trapezoidal cross-section. Qhov ntu ntu ntu ntawm tag nrho cov hlau nplaum yog qhov tsis tu ncua n-sided (n=8-64), thiab cov kev taw qhia magnetization ntawm txhua qhov sib nqus hlau nplaum uas nyob ib sab txawv ntawm 360 / n degrees hauv ib ntus. Tsis pub dhau 45 degree kaum sab xis nyob rau hauv kab rov tav thiab ntsug, nruab nrab ntawm cov hlau nplaum ruaj khov yog cov hlau tsis huv, ze rau qhov chaw nruab nrab, cov khoom siv sib nqus mos muab tso rau hauv kab rov tav yog cov hlau tsis sib nqus, tsis muaj hlau nplaum. steel los yog txhuas, thiab thaj chaw ncig ntawm qhov chaw nruab nrab yog qhov sib txawv ntawm huab cua, uas yog qhov chaw ua haujlwm muaj zog sib nqus. Txhua yam khoom yog glued mus rau hauv lub hollow octagonal prism, thiab sab nraud yog nruj nreem kaw nrog lub plhaub uas tsis yog hlau nplaum. Cov ntaub ntawv 97111733.0 muaj feem xyuam rau cov khoom siv hlau nplaum ruaj khov nrog cov khoom xeb tiv taus, haum rau kev lag luam xws li tshuaj thiab lub zog. Kev siv 200610031653.1 hais txog kev ua haujlwm siab Re Fe B raws li nanocomposite cov hlau nplaum ruaj khov uas muaj titanium thiab carbon. Cov ntaub ntawv 97115671.9 muaj feem xyuam rau cov khoom siv hlau nplaum neodymium boron nano.
Txoj kev npaj muaj xws li cov kauj ruam hauv qab no: tau txais R (tsis tshua muaj lub ntiaj teb) - Fe-B raw khoom hmoov, thauj khoom rau hauv SPS tshwj xeeb pwm rau kev sib nqus teb thiab molding; Ua cov pa roj plasma sintering ntawm cov hmoov thiab pwm nyob rau hauv lub tshuab nqus tsev los yog inert gas tiv thaiv. sintering tej yam kev mob yog: cua kub tus nqi 30 mus rau 300 degree / feeb, sintering kub 700 rau 900 degree, siab 10 mus rau 700MPa, tuav lub sij hawm 0 mus rau 30 feeb, txias npaum li cas 10 mus rau 100 degree / feeb; Tom qab sintering, cov hlau nplaum tau txais kev kho cua sov thib ob, nrog rau thawj theem kev kho cua sov kub ntawm 900 txog 1100 degree rau 1 mus rau 3 teev, thiab theem thib ob thaum tshav kub kub kho kub ntawm 600 txog 900 degree rau 1 mus rau 3 teev.
