TC cov kabmob txais yuav cov txheej txheem sintering dav dav ntawm cov cua sov zoo tib yam, cov txheej txheem sib xyaw tshwj xeeb
Nyuaj tswj hwm cov khoom siv raw kom ntseeg tau tias cov cemented carbide thiab tungsten carbide ua tau raws li cov qauv siv.
Cov txheej txheem tsim cov sintering nruj me ntsis tau ua tiav, yog li cov txheej txheem sintering tau ua kom sov thiab khaws cia tag nrho raws li qhov ntsuas kub nce nkhaus.
Txais yuav cov txheej txheem tiv thaiv qib siab tshaj plaws, cov khoom siv sintered tsis oxidize nyob rau hauv qhov kub thiab txias, ua kom lub ntsej muag ua kom huv, cov kua ua kom yaj tau nkag tau zoo, thiab txheej sintered shrinks tusyees, uas tsis tsuas yog tshem tawm tag nrho cov kev ua txhaum xws li kev nqaim thiab porosity , tab sis kuj tiv thaiv kev tawg thaum lub sij hawm sintering. Qhov teeb meem yog tias txheej sintered tau khov kho ua ke nrog cov substrate, thiab koom ua ke rau hauv ib lub cev yam tsis muaj tev tawm. Lub zog ntawm cov cemented carbide siv yog siab thiab qhov nyuaj yog siab. Qhov teeb meem tev thiab tawg tsis tshwm sim thaum siv, thiab nws tiv taus txhawm rau cuam tshuam, cuam tshuam thiab xeb hauv qhov xwm txheej ua haujlwm hnyav, thiab lub neej ua haujlwm tuaj yeem ncav ntau dua 200 teev.
