Nyob rau hauv "khoom siv ntiaj teb" ntawm kev lag luam kev lag luam, titanium carbide (TiC), silicon carbide (SiC), thiab cemented carbide (feem ntau raws li tungsten carbide - cobalt, thiab lwm yam) yog peb lub ci ci "cov ntaub ntawv hnub qub". Nrog lawv cov khoom tshwj xeeb, lawv ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Niaj hnub no, peb yuav ua tib zoo saib qhov sib txawv ntawm cov khoom ntawm peb cov ntaub ntawv no thiab cov xwm txheej uas lawv ua tau zoo!
I. Ib Lub Taub Hau - rau - Lub Taub Hau Sib piv ntawm Cov Khoom Siv Khoom

Cov khoom tawg yooj yim:
- Titanium Carbide (TiC): Nws hardness yog ze rau ntawm pob zeb diamond, ua rau nws yog ib tug tswv cuab ntawm super - khoom nyuaj tsev neeg. Nws lub siab ntom ua rau kom pom tseeb qhov chaw nyob rau hauv precision cov cuab yeej uas yuav tsum tau "hnyav". Txawm li cas los xij, nws muaj lub siab brittleness thiab nws yooj yim rau chipping nyob rau hauv kev cuam tshuam, yog li nws yog qhov tsim nyog rau qhov zoo li qub, tsis tshua muaj kev cuam tshuam / hnav - resistant scenarios. Piv txwv li, nws feem ntau yog siv los ua txheej txheej ntawm cov cuab yeej. TiC txheej yog super - tawv thiab hnav - resistant, zoo li muab "tiv thaiv armor" ntawm high-speed steel thiab cemented carbide cov cuab yeej. Thaum txiav stainless hlau thiab hlau alloy, nws tuaj yeem tiv taus qhov kub thiab txias, txo qhov hnav, ua kom lub neej ntev ntev. Piv txwv li, nyob rau hauv lub txheej ntawm xov milling cutters, nws enables ceev thiab ruaj khov txiav.

Nyob rau hauv lub xeev ceramic, nws cov tshuaj ruaj khov yog qhov zoo tshaj plaws thiab nws tsis tshua muaj kev cuam tshuam nrog cov kua qaub thiab alkalis (tshwj tsis yog qee qhov zoo li hydrofluoric acid). Txawm li cas los xij, brittleness yog qhov teeb meem tshwm sim rau cov khoom siv ceramic. Txawm li cas los xij, ib leeg - siv lead ua silicon carbide (xws li 4H - SiC) tau txhim kho cov tawv nqaij thiab ua kom rov qab los hauv cov khoom siv hluav taws xob thiab cov khoom siv ntau zaus. Piv txwv li, SiC - cov cuab yeej siv ceramic yog "cov tub ntxhais kawm sab saum toj" ntawm cov cuab yeej ceramic. Lawv muaj siab - kub tsis kam thiab tshuaj stability. Thaum txiav high - hardness alloys (xws li npib tsib xee - raws li alloys) thiab nkig cov ntaub ntawv (xws li cam khwb cia hlau), lawv tsis yooj yim rau cov cuab yeej sticking thiab muaj qeeb hnav. Txawm li cas los xij, vim brittleness, lawv zoo dua rau kev ua tiav nrog kev cuam tshuam tsawg dua thiab siab precision.
- Cemented Carbide (WC - Co): Ib tug "sab saum toj - tier player hauv qhov txiav"! Los ntawm cov cuab yeej tshuab dhos rau CNC milling cutters, los ntawm milling steel mus rau drilling pob zeb, nws tuaj yeem pom nyob txhua qhov chaw. Cemented carbide nrog cov ntsiab lus qis Co (xws li YG3X) yog qhov tsim nyog rau kev ua tiav, thaum uas muaj cov ntsiab lus Co siab (xws li YG8) muaj kev cuam tshuam zoo thiab tuaj yeem ua haujlwm ntxhib machining tau yooj yim. Cov theem nyuaj ntawm WC yog lub luag haujlwm rau "sawv" hnav, thiab Co binder ua zoo li "kua nplaum" los tuav WC cov khoom ua ke, tuav ob qho tib si hardness thiab toughness. Txawm hais tias nws qhov siab - qhov kub thiab txias tsis zoo li thawj ob, nws qhov kev ua tau zoo tag nrho ua rau nws haum rau ntau yam xwm txheej los ntawm kev txiav rau hnav - cov khoom tiv thaiv.
II. Daim ntawv thov teb nyob rau hauv tag nrho viav vias

2. Hnav – Resistant Component teb
- Titanium Carbide (TiC): Ua raws li "hnav-tiv taus tus yeej" hauv cov pwm precision! Piv txwv li, nyob rau hauv cov hmoov metallurgy pwm, thaum nias hlau hmoov, TiC inserts yog hnav - resistant thiab muaj siab precision, xyuas kom meej tias cov pressed qhov chaw muaj qhov tseeb qhov ntev thiab zoo nto, thiab tsis muaj "malfunction" thaum lub sij hawm ntau lawm.
- Silicon Carbide (SiC): Endowed nrog "ob buffs" ntawm hnav tsis kam thiab siab - kub tsis kam! Rollers thiab bearings nyob rau hauv high-temperature furnaces ua los ntawm SiC ceramics tsis soften los yog hnav txawm saum toj no 1000 ℃. Tsis tas li ntawd, cov nozzles hauv cov khoom siv sandblasting ua los ntawm SiC tuaj yeem tiv taus qhov cuam tshuam ntawm cov xuab zeb, thiab lawv lub neej kev pab cuam yog ob peb zaug ntev dua li ntawm cov hlau nozzles.
- Cemented Carbide (WC - Co): "Ntau yam hnav - tus kws tshaj lij tiv thaiv"! Cemented carbide cov hniav hauv kuv cov khoom tho tuaj yeem tsoo pob zeb yam tsis muaj kev puas tsuaj; cemented carbide cutters ntawm cov ntaub thaiv npog tshuab cov cuab yeej tuaj yeem tiv taus cov av thiab cov xuab zeb, thiab tuaj yeem "ua kom lawv nyob zoo" txawm tias tom qab tunneling ntau txhiab meters. Txawm tias lub log eccentric hauv xov tooj ntawm tes vibration motors cia siab rau cemented carbide rau hnav tsis kam los xyuas kom ruaj khov kev co.
3. Electronics / Semiconductor Field
- Titanium Carbide (TiC): tshwm sim hauv qee yam khoom siv hluav taws xob uas xav tau qhov kub thiab txias thiab hnav tsis kam!
