Raws li ib qho tseem ceeb ntawm cov teb muaj kev ua lag luam, kev ua tau zoo ntawm tungsten carbide khawm yog inseparable ntawm cov txheej txheem tsim khoom.
Thawj yog kev npaj ntawm cov ntaub ntawv raw. Tungsten thiab cobalt cem cov carbides feem ntau yog siv los tsim tungsten carbide khawm, thiab tungsten carbide, cobalt thiab lwm yam hmoov sib xyaw ua feem. Cov hmoov no yuav tsum tau ua kom zoo thiab ua tiav cov txheej txheem kom ruaj khov thiab muaj kev coj dawb huv, tso lub hauv paus rau cov txheej txheem tsim khoom tom ntej.
Tom ntej no los cov hmoov moulding theem. Cov hmoov sib xyaw yog nias hauv qab siab rau hauv lub siab thaum pib cov kaus hniav los ntawm cov pwm tshwj xeeb. Tus txheej txheem no yuav tsum tau kho kom meej thiab ntsuas kub kom ntseeg tau tias muaj kev sib dhos thiab qhov ntev ntawm cov hniav. Txawm hais tias nias tus txhuam hniav lub cev twb muaj qee qhov zoo, nws tseem tsis yooj yim.
Qhov no yog ua raws li cov txheej txheem Sintering. Tus kheej lub cev txhuam hniav yog sintered nyob rau hauv lub siab-kub sintering rauv, thiab nyob rau hauv qhov kev ua diffuse thiab sib xyaw ua ke los ua tus qauv carbide muaj zog carbide. Cov tsis muaj xws li kub, lub sijhawm thiab huab cua ntawm cov sintering yuav tsum tau nruj nreem kom ntseeg tau cov hniav zoo. Tom qab sintering, cov khoom ntawm cov hniav cov hniav xws li hardness, lub zog thiab coj kev tawm tsam tau zoo heev.
Txhawm rau txhawm rau txhim kho qhov chaw zoo thiab qhov tseeb ntawm cov hniav cov hniav, kos rau tom qab. Piv txwv, sib tsoo, polishing thiab lwm cov txheej txheem tau siv los ua kom cov pob ntawm cov hniav smoother thiab qhov loj dua. Nyob rau tib lub sijhawm, raws li cov khoom siv sib txawv, cov pob cov kaus hniav tuaj yeem tseem tuaj yeem ua tau, xws li titanium nitride plating, etc. Anti-corrosion thiab lwm yam khoom.
Kev soj ntsuam zoo yog nqa tawm thoob plaws hauv kev tsim khoom. Los ntawm kev tshuaj xyuas cov khoom siv raw, rau kev sim cov khoom lag luam nruab nrab hauv txhua qhov kev tsim cov khoom lag luam, txhua kauj ruam ntawm txoj kev ua tau zoo tias qhov zoo ntawm cov hniav sib dhos ua ke. Tsuas yog cov hniav spherical uas tau dhau ntau yam kev sim tuaj yeem muab tso rau hauv cov ntawv thov kev kawm.
