Raws li cov khoom tseem ceeb hauv kev lag luam, kev ua haujlwm zoo ntawm tungsten carbide khawm yog sib cais los ntawm cov txheej txheem tsim khoom zoo.
Thawj yog kev npaj cov khoom siv raw. tungsten thiab cobalt cemented carbides feem ntau yog siv los tsim tungsten carbide khawm, thiab tungsten carbide, cobalt thiab lwm yam hmoov sib tov hauv ib qho kev faib ua feem. Cov hmoov no yuav tsum tau kuaj xyuas kom zoo thiab ua tiav kom ntseeg tau tias cov khoom me me thiab cov purity siab, tso lub hauv paus rau cov txheej txheem tsim khoom tom ntej.
Tom ntej no yog cov hmoov molding theem. Cov hmoov sib tov yog nias nyob rau hauv kev kub siab rau hauv thawj cov duab ntawm cov hniav kheej kheej los ntawm ib qho pwm tshwj xeeb. Cov txheej txheem no yuav tsum muaj kev tswj xyuas qhov siab thiab qhov kub thiab txias kom ntseeg tau tias qhov sib txawv ntawm cov hniav thiab qhov tseeb qhov ntev ntawm cov hniav. Txawm hais tias lub cev txhuam hniav uas tau nias lub cev twb muaj qee yam zoo li, nws tseem tsis yooj yim.
Qhov no yog ua raws li cov txheej txheem sintering. Lub cev hniav kheej kheej yog sintered nyob rau hauv qhov kub-kub sintering rauv, thiab nyob rau hauv qhov kev txiav txim ntawm kub kub, cov hmoov hais diffuse thiab ua ke los tsim ib tug muaj zog cemented carbide qauv. Tsis muaj xws li qhov kub thiab txias, lub sij hawm thiab cua ntawm sintering yuav tsum tau nruj me ntsis tswj los xyuas kom meej cov hniav zoo. Tom qab sintering, cov khoom ntawm pob hniav xws li hardness, lub zog thiab hnav tsis kam tau zoo heev.
Txhawm rau txhawm rau txhim kho qhov zoo ntawm qhov chaw thiab qhov tseeb ntawm cov hniav pob, kev ua haujlwm tom ntej kuj tau ua. Piv txwv li, kev sib tsoo, polishing thiab lwm yam txheej txheem yog siv los ua kom lub ntsej muag ntawm pob hniav smoother thiab qhov loj dua qhov tseeb. Nyob rau tib lub sijhawm, raws li kev thov sib txawv, cov hniav pob kuj tuaj yeem coated, xws li titanium plating, titanium nitride plating, thiab lwm yam, los txhim kho lawv cov kev tiv thaiv hnav, tiv thaiv corrosion thiab lwm yam khoom.
Kev tshuaj xyuas zoo yog nqa tawm thoob plaws hauv kev tsim khoom. Los ntawm kev tshuaj xyuas cov ntaub ntawv raw, mus rau kev ntsuam xyuas cov khoom nruab nrab hauv txhua txoj kev tsim khoom, mus rau qhov kev xeem ntawm cov khoom kawg, txhua kauj ruam ntawm txoj kev ua kom ntseeg tau tias qhov zoo ntawm cov hniav kheej kheej ua tau raws li cov qauv nruj. Tsuas yog cov hniav spherical uas tau dhau los ntawm ntau yam kev ntsuam xyuas tuaj yeem muab tso rau hauv daim ntawv thov.
