Qhov zoo ntawm tungsten carbide

Qhov zoo ntawm tungsten carbide feem ntau yog tshwm sim hauv cov hauv qab no:

1. Kub corrosion kuj: Tungsten carbide tseem tuaj yeem tswj cov khoom siv tshuaj lom neeg ruaj khov nyob rau hauv qhov kub thiab txias, thiab tsis yooj yim rau oxidized thiab corroded.

2. Oxidation kuj: Tungsten carbide tsis yooj yim rau oxidize ntawm qhov kub thiab txias, thiab tuaj yeem tiv taus oxidation yaig.

3. Siab zog thiab hardness: tungsten carbide muaj lub siab tawv thiab lub zog, tuaj yeem tiv taus kev ntxhov siab thiab siab load ib puag ncig.

4. Zoo hnav tsis kam: Tungsten carbide muaj kev hnav zoo thiab tuaj yeem tiv taus kev sib txhuam thiab hnav.

Disadvantages ntawm tungsten carbide

Txawm hais tias tungsten carbide muaj ntau qhov zoo, nws kuj muaj qee qhov tsis zoo.Ua ntej tshaj plaws, kev ua haujlwm ntawm tungsten carbide yog qhov nyuaj thiab xav tau cov cuab yeej tshwj xeeb thiab cov txheej txheem.Qhov thib ob, tus nqi ntawm tungsten carbide yog qhov siab, uas txwv nws daim ntawv thov hauv qee qhov chaw.Tsis tas li ntawd, tungsten carbide cuam tshuam tsis zoo, tsis muaj zog, yuav tsum tau them sai sai rau.

Kev txhim kho yav tom ntej ntawm tungsten carbide

Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, tungsten carbide muaj peev xwm loj hlob rau yav tom ntej.Ua ntej tshaj plaws, cov ntaub ntawv tshiab ntawm tungsten carbide tau tsim los tas li, xws li nano tungsten carbide, composite tungsten carbide, thiab lwm yam, uas muaj kev ua tau zoo dua thiab ntau yam kev siv.Qhov thib ob, txoj kev npaj tshiab thiab thev naus laus zis kuj tseem tshwm sim, xws li tshuaj lom neeg vapor deposition, plasma li, thiab lwm yam, uas tuaj yeem npaj cov khoom siv tungsten carbide zoo dua.

Yuav ua li cas siv tungsten carbide rationally

Txhawm rau siv tungsten carbide tsim nyog, peb yuav tsum xub nkag siab nws cov khoom thiab cov yam ntxwv, thiab xaiv cov khoom siv tungsten carbide zoo raws li kev thov sib txawv.Qhov thib ob, peb yuav tsum tau them sai sai rau kev xaiv cov txheej txheem kev ua haujlwm, tsis txhob ua ntau dhau thiab kev kho kub kub, txhawm rau tswj kev ua haujlwm thiab ruaj khov ntawm tungsten carbide.Tsis tas li ntawd, peb yuav tsum xyuam xim rau kev tiv thaiv ib puag ncig thiab teeb meem kev nyab xeeb, thiab txo qis kev tsim khoom pov tseg thiab kev cuam tshuam ib puag ncig ntau li ntau tau.

Hauv luv luv, tungsten carbide yog cov khoom siv dav siv thiab kev txhim kho yav tom ntej, thiab nws qhov kev cia siab rau hauv ntau qhov chaw yog dav.Los ntawm kev tshawb fawb txuas ntxiv thiab kev tsim kho tshiab, peb muaj kev ntseeg siab tias peb yuav ua kom zoo dua ntawm cov khoom siv zoo tshaj plaws nyob rau yav tom ntej thiab pab txhawb kev txhim kho ntawm tib neeg lub neej.
