Raws li ib txwm tsis tshua muaj - cov khoom siv hlau nplaum hauv ntiaj teb, cov hlau nplaum neodymium tsis yog tsuas yog khav theeb ua lub cev, tab sis lawv cov tsos kuj qhia txog qhov txawv ntawm lawv cov khoom muaj pes tsawg leeg thiab cov txheej txheem tsim khoom. Los ntawm kev soj ntsuam cov duab, xim, saum npoo av, thiab geometric precision ntawm neodymium hlau nplaum, kev txiav txim ua ntej tuaj yeem ua rau lawv cov khoom tseem ceeb thiab cov txheej txheem ua haujlwm, uas muaj cov txiaj ntsig siv hauv kev lag luam thiab kev tswj xyuas kom zoo.
Los ntawm kev pom macroscopic, cov hlau nplaum neodymium feem ntau pom cov duab geometric tsis tu ncua, suav nrog lub voj voog, squares, rings, vuas, thiab ntau yam duab tsis zoo. Cov duab no feem ntau tau los ntawm sintered blanks los ntawm cov txheej txheem xws li txiav, xaim txiav, lossis pwm tsim. Cov npoo yog ncaj los yog muaj cov curvatures tshwj xeeb, thiab qhov tseeb qhov tseeb tuaj yeem tswj tau ntawm theem siab kom ua tau raws li qhov yuav tsum tau ua los ua ke xws li lub cev muaj zog qhov haum thiab qhov ntsuas qhov ntsuas. Bonded neodymium hlau nplaum tuaj yeem tsim rau hauv ntau qhov kev sib txuas hauv ib kauj ruam, txo cov kev ua haujlwm tom ntej, uas muaj ntau hauv microelectronic li.
Nyob rau hauv cov nqe lus ntawm cov xim thiab kev ntxhib los mos, sintered neodymium hlau nplaum muaj ib tug silver -grey los yog greyish me ntsis -dub metallic luster, ib tug ntuj tsos tshwm sim los ntawm kev sib cuam tshuam ntawm hlau{2}}raws li alloys thiab tsis tshua muaj ntiaj teb cov ntsiab lus. Vim cov khoom siv siab hardness thiab brittleness, polished nto muaj ib tug ilv xim hlau zoo nkauj, thaum unfinished nto tej zaum yuav khaws tau hloov maj mam machining textures los yog granular marks. Qhov saum npoo yog feem ntau coated nrog anti- txheej txheej corrosion, feem ntau npib tsib xee- tooj liab-nickel, zinc, epoxy resin, lossis phosphating films, nrog cov xim sib txawv nyob ntawm hom txheej: npib tsib xee- cov txheej txheem feem ntau yog cov nyiaj ci los yog lub teeb kub, zincite coatings{9} yog grey coatings, thiab cov xim sib txawv ntawm cov xim sib txawv nyob ntawm seb hom xim: npib tsib xee matte dub lossis ib qho xim tshwj xeeb, ua haujlwm zoo nkauj thiab tiv thaiv.
Tus ntoo khaub lig- cov yam ntxwv ntawm cov hlau nplaum neodymium yog qhov tseem ceeb rau kev txheeb xyuas lawv cov qauv sab hauv. Cov khoom sintered muaj qhov ntom ntom thiab sib xws -section, nyuaj, thiab ua suab nrov thaum ntaus. Hauv kev nthuav dav, cov qauv zoo granular pom. Cov khoom lag luam tsis zoo lossis tsis sib xws tuaj yeem pom qhov pores, tawg, lossis delamination, cuam tshuam rau lawv cov khoom sib nqus thiab lub zog txhua yam. Bonded neodymium hlau nplaum nthuav tawm ib txheej txheej los yog granular cross-section, xav tias sib dua, thiab muaj zog zoo dua li cov hlau nplaum sintered.
Dimensional thiab geometric tolerances kuj yog cov cim tseem ceeb ntawm cov tsos zoo. High-kawg daim ntawv thov feem ntau xav tau cov hlau nplaum txoj kab uas hla, thickness, coaxiality, los yog flatness yuam kev yuav tsum tau tswj nyob rau hauv tsis tshua muaj me me ntau yam kom tsis txhob magnetic teb inhomogeneity los yog txhua yam cuam tshuam los ntawm kev sib txawv deviations. Yog li ntawd, precision-machined neodymium hlau nplaum feem ntau pom cov npoo thiab cov ces kaum, zoo ib yam ntawm qhov chaw tiaj tus, thiab cov txheej txheem plating.
Overall, the appearance characteristics of neodymium magnets are shaped by the material's inherent properties, molding process, and surface treatment, reflecting both their high hardness and high density physical properties, as well as industrial processing precision and protection levels. Kev txheeb xyuas thiab txheeb xyuas cov yam ntxwv no pab ua kom muaj txiaj ntsig zoo dua thiab kev xaiv muaj txiaj ntsig hauv kev tsim khoom, tshuaj xyuas, thiab kev siv theem.
