Nws muaj feem xyuam rau cov ntsiab lus ntawm cobalt nyob rau hauv lub binder theem nyob rau hauv lub alloy, raws li zoo raws li lub grain zoo thiab dispersion (cobalt txheej thickness) ntawm cobalt, raws li zoo raws li lub lattice distortion, nyob rau hauv kev nyuaj siab thiab muaj impurities ntawm cobalt.Feem ntau hais lus, lub zog quab yuam ntawmcemented carbidetxo nrog nce ntawmcobaltcov ntsiab lus;Qhov ntau dua qhov dispersion ntawm cobalt, qhov siab dua qhov coercive force.
Yog li ntawd, lub zog quab yuam tuaj yeem siv los ua qhov ntsuas tsis ncaj ntawm qhov loj ntawm tungsten carbide crystal nplej.Parameter;coercivity kuj muaj feem xyuam rau cov ntsiab lus carbon hauv cov hlau.Rau cov alloys ntawm tib yam muaj pes tsawg leeg, raws li cov ntsiab lus carbon nce, H yuav txo.Thaum Hc tsawg dhau, carburization yuav tshwm sim;thaum tus nqi yog txawv txav
Carbon deficiency lossis txawm tias decarburization eta theem yuav tshwm sim.Kev ntsuas ntawm lub zog quab yuam ntawm cemented carbide muaj qhov taw qhia zoo rau cov txheej txheem.Kev sib raug zoo ntawm lub zog quab yuam Hc thiab lwm yam tsis zoo ntawm lub cev xws li hardness, ntom, cobalt hlau nplaum, thiab lwm yam tuaj yeem ua lub luag haujlwm hauv kev tswj cov txheej txheem tsim khoom.cemented carbide.Lub luag haujlwm saib xyuas zoo.
