Muaj cov txheej txheem tseem ceeb heev hauv cov txheej txheem ntawm cov hniav cermet, vim nws ncaj qha cuam tshuam rau lub neej thiab siv cov nyhuv ntawm cov hniav, nws yog passivation ntawm cov hniav ntug. Kev kho mob Passivation feem ntau yog hais txog cov txheej txheem tom qab cov hniav yog finely hauv av, lub hom phiaj yog ua kom lub txiav ntug du thiab du, thiab ntev lub neej ntawm lub cuab tam.
Vim hais tias cov hniav ntug yog sharpened los ntawm lub sib tsoo log, txawm hais tias nws tsis tuaj yeem pom los ntawm qhov muag liab qab, nws tuaj yeem pom los ntawm cov cuab yeej uas muaj cov chipping me me thiab serrations mus rau qhov sib txawv. Nyob rau hauv cov txheej txheem ntawm high-ceev txiav thaum lub sij hawm tsim thiab ua, qhov sib txawv me me ntawm cov hniav ntug yog ib qho yooj yim mus nthuav, uas ua rau kom hnav thiab vau ntawm cov hniav.
Lub luag haujlwm ntawm ntug passivation:
1. Rounding ntawm ntug txiav: tshem tawm cov burrs ntawm ntug txiav thiab ua tiav qhov sib npaug thiab sib npaug.
2. Cov burrs ntawm qhov txiav ntug ua rau hnav ntawm cov hniav, thiab qhov chaw ntawm cov txheej txheem ua haujlwm tseem yuav ua ntxhib. Tom qab kev kho mob passivation, lub txiav ntug yuav du heev, uas zoo heev txo cov chipping thiab txhim kho cov nto tiav ntawm workpiece.
3. Ua tib zoo txhuam cov cuab yeej zawj txhawm rau txhim kho qhov zoo thiab txiav kev ua haujlwm.
Txawm li cas los xij, muaj qhov tshwj xeeb hauv kev tsim cov cermet finely av hniav, uas yog, cov hniav tsis passivated tom qab zoo sib tsoo. Peb hu lawv cov khoom ntse ntse, uas yog, cov khoom tsis muaj passivation.
Cia peb saib ob daim duab ua ntej kom pom qhov tshwm sim ntawm cov khoom tsis muaj passivation- "ntse ntug", yog vim li cas nws tsis tuaj yeem passivated.
Koj tuaj yeem pom tias txawm tias tsis muaj kev kho mob passivation tau ua tiav, kev txiav ntug yog du thiab du, tsis muaj chipping thiab jaggedness, uas tag nrho mus txog qib uas tsis tas yuav tsum muaj passivation. Muaj ntau yam khoom zoo sib xws hauv peb lub tuam txhab cov khoom lag luam, thiab cov qauv yuav muaj tsab ntawv F thaum kawg, qhia tias nws yog cov khoom ntse ntse tsis muaj passivation.
Piv txwv li: passivation khoom specification yog TNGG160408R15M
Qhov tshwj xeeb ntawm qhov tsis-passive ntse ntug yog TNGG160408R15MF
Txij li thaum lub luag hauj lwm ntawm passivation yog los txhim kho lub neej thiab nto zoo, yog vim li cas cov khoom ntse-edged tsim?
Lub hom phiaj tseem ceeb yog los xyuas kom meej qhov zoo nkauj tiav thiab brisk txiav nyhuv hauv kev ua thiab ntau lawm. Nws tuaj yeem txo cov khoom txiav thiab ua tiav cov nyhuv siab heev thaum ua cov khoom me me thiab cov khoom siv. Txawm hais tias lub neej ntawm cov khoom ntse ntse tuaj yeem raug txo qis piv rau cov khoom lag luam blunted, cov npoo ntse yog qhov zoo tagnrho rau kev xav tau kev siv tshuab.
