Ua ntej
Hniav txheej tshuab yog ib qho ntawm cov thev naus laus zis tseem ceeb hauv kev lag luam niaj hnub txiav hniav, thiab cov ntaub ntawv thiab cov txheej txheem txiav hu ua peb tus ncej ntawm kev txiav hniav. Txheej tshuab los ntawm cov hniav substrate coated nrog ib los yog ntau txheej ntawm siab hardness, siab hnav-resistant cov ntaub ntawv, ho txhim kho cov hniav hnav tsis kam, oxidation kuj, anti-adhesion, thermal shock kuj thiab lwm yam kev ua tau zoo, thiaj li mus cuag lub neej. ntawm cov hniav, txhim kho tej efficiency thiab machining raug.
Txheej khoom
Kev tuav lub slotter blades nyob rau hauv qhov kev pom zoo yog qhov tseem ceeb rau kev ncua lawv lub neej thiab ua kom muaj kev ua tau zoo ib yam. Kev saib xyuas kom raug suav nrog kev tu kom tsis tu ncua, tshuaj xyuas kev hnav lossis kev puas tsuaj, thiab ua kom nrawm nrawm lossis hloov cov hniav raws li xav tau. Khaws cov hniav kom huv si los ntawm cov khib nyiab thiab cov khoom ua kom txias kom tsis txhob hnav ntxov ntxov thiab tswj kev txiav txiav. Kev tshuaj xyuas cov hniav rau txhua qhov cim ntawm kev hnav, xws li cov chips lossis cov npoo npub, tso cai rau kev saib xyuas raws sijhawm kom tsis txhob muaj kev puas tsuaj rau cov khoom ua haujlwm. Ntsej muag lossis hloov cov hniav thaum tsim nyog ua kom muaj txiaj ntsig zoo thiab tiv thaiv cov teeb meem zoo hauv cov khoom siv.
Muaj ntau hom hniav txheej txheej, feem ntau suav nrog carbide, nitride, carbon-nitride, oxide, boride, silicide, pob zeb diamond thiab cov txheej txheem sib xyaw. Cov ntaub ntawv txheej txheej yog:
(1) titanium nitride txheej
Titanium nitride txheej, los yog TiN txheej, yog ib qho nyuaj ceramic hmoov nrog cov xim daj daj uas tuaj yeem siv ncaj qha mus rau lub substrate ntawm cov khoom los tsim cov txheej nyias.TiN txheej yog feem ntau siv rau ntawm cov hniav ua los ntawm txhuas, hlau, titanium alloys. thiab carbide.
TiN txheej yog cov ntaub ntawv nruj uas ua rau kom muaj zog thiab ua haujlwm ntev ntawm cov khoom siv, nrog rau kev hnav thiab kev sib txhuam. Tus nqi ntawm TiN feem ntau yog qis, uas ua rau nws zoo tagnrho rau cov tuam txhab nrhiav kev daws teeb meem tus nqi.
(2) TITANIUM CARBON NITRIDE
TiCN yog txheej txheej uas sib xyaw titanium, carbon thiab nitrogen los tsim cov txheej txheem uas pab txhawb kev lag luam hniav. Ntau daim ntawv thov yog tib yam li TiN txheej, txawm li cas los xij, TiCN txheej tuaj yeem ua tau zoo dua hauv cov ntawv thov tshwj xeeb nrog cov tawv tawv dua, thiab feem ntau xaiv thaum txiav cov ntaub ntawv nyuaj.
TiCN yog ib puag ncig tus phooj ywg txheej uas tsis muaj tshuaj lom thiab FDA ua raws. Cov txheej muaj zog adhesion thiab tuaj yeem siv rau ntau yam khoom siv. Muaj cov hniav coated nrog TiCN muaj xim grey xim, uas tsis tsuas yog muab siab corrosion thiab hnav tsis kam, tab sis kuj tseem txuas ntxiv lub neej ntawm cov hniav los ntawm kev tiv thaiv qis qis thiab txo kev puas tsuaj (xws li splintering) uas tshwm sim thaum lub sijhawm ua haujlwm.
(3) Pob zeb diamond zoo li CARBON txheej
DLC yog cov khoom tsim los ntawm cov txiv neej nrog cov khoom zoo ib yam li cov pob zeb diamond ntuj, greyish-dub xim thiab tiv taus corrosion, abrasion thiab scuffing, DLC txheej yog siv rau cov hniav nyob rau hauv daim ntawv ntawm vapor lossis roj, uas kho tau los pab. txhim kho kev tiv thaiv cov yam ntxwv ntawm kev lag luam riam.
DLC yog thermally ruaj khov mus txog li 570 degrees Fahrenheit, ua rau nws zoo tagnrho rau siv nyob rau hauv huab cua kub thiab tej yam kev mob, thiab DLC txheej kuj pab muaj riam phom tiv thaiv degradation deg los ntawm ntau yam xws li av noo, roj thiab dej ntsev.
(4) TEFLON dub NONSTICK txheej
Teflon dub non-stick coatings feem ntau yog siv los ntawm kev lag luam hniav los txo qhov tsim ntawm cov nplaum nplaum, cov khoom noj khoom haus thiab cov yas, thiab cov txheej txheem no muaj ntau yam txiaj ntsig, suav nrog kev ua kom zoo heev thiab kev tiv thaiv corrosion, thiab tseem yog FDA pom zoo, ua. nws zoo tagnrho rau kev lag luam ua zaub mov.
(5) HARD CHROME
Hard chrome yog ib qho txheej txheem uas feem ntau siv hauv kev ua tiav. Hard chrome coatings tiv thaiv corrosion, abrasion thiab hnav, ua rau nws yog ib qho zoo tshaj plaws coatings nyob rau hauv ib tug ntau yam ntawm industries.Hard chrome yog zoo tagnrho rau cov ntaub ntawv xws li hlau vim nws pab tiv thaiv corrosion thiab oxidation thaum tseem pab tswj cov tawv tawv.
(6) POLYTETRAFLUORETHYLENE
PTFE yog cov txheej txheem yooj yim heev nrog kev ua haujlwm zoo rau feem ntau cov ntsiab lus. Nrog lub melting point me ntsis saum toj no 600 degree Fahrenheit ntau, PTFE tuaj yeem ua tau ntau yam kub. PTFE kuj tseem tiv taus cov tshuaj thiab muaj hluav taws xob tsawg, tso cai rau nws siv los ua cov hniav txheej rau ntau yam kev siv.
Tsis tas li ntawd, muaj ntau yam txheej txheej xws li CrN, TiC, Al₂O₃, ZrN, MoS₂, thiab lawv cov txheej txheem sib xyaw xws li TiAlN, TiCN-Al₂O₃-TiN, thiab lwm yam. cov hniav
Qhov ntawd yog tag nrho rau kab lus no. Yog tias koj xav tau cov hniav muaj los yog muaj qee cov lus nug txog nws, koj tuaj yeem tiv tauj peb ncaj qha.
Tom qab ntawd, Peb yuav hloov kho cov ntaub ntawv txuas ntxiv, thiab koj tuaj yeem nrhiav cov ntaub ntawv ntxiv ntawm peb lub vev xaib (passiontool.com) blog.
Tau kawg, koj tuaj yeem them sai sai rau peb Cov Kev Tshaj Lij Tshaj Lij Tshaj Tawm:
