Hom alloy no hu ua YG hom alloy.Cov qauv ib txwm muaj ntawm WC-Co alloy dawb yog ob-theem alloy muaj li ntawm polygonal WC theem thiab kev sib txuas theem Co. Qee zaum tsawg dua 2% ntawm lwm yam (tantalum, niobium, chromium, vanadium)carbidesyog ntxiv raws li additives rau cov hniav txiav los yog kos tuag kom lub neej kev pab cuam ntawm lub cuab tam.Txawm li cas los xij, qhov no tsis hloov qhov kev ua tau zoo ntawm cov hlau, thiab nws tseem yog WC-Co hom cemented carbide.Piv nrog rau lwm cov cemented carbides nrog tib cov ntsiab lus cobalt, hom alloy no muaj lub siab tshaj plaws flexural zog, compressive zog, cuam tshuam toughness thiab elastic modulus, nrog rau ib tug me me linear expansion coefficient.
Raws litungsten carbidenplej, hom cemented carbide no feem ntau muab faib ua peb pawg: coarse grain, medium grain thiab fine grain.Nrog rau kev txhim kho cov ntaub ntawv ua tiav thiabcemented carbideCov txheej txheem ntau lawm, WC nplej ntawm WC-Co alloys tau tsim zoo heev rau ntawm ultra-coarse thiab ultra-zoo kawg.
