① Kuomarara kwepamusoro: simende yecarbide chishandiso inogadzirwa necarbide ine kuoma kwakanyanya uye nzvimbo yekunyungudika (inonzi chikamu chakaoma) uye simbi binder (inonzi bonding chikamu) nehupfu simbi nzira, kuoma kwayo kunosvika 89 ~ 93HRA, yakanyanya kukwirisa kupfuura simbi yekumhanya, pa 5400C, kuoma kuchiri kukwanisa kusvika 82 ~ 87HRA, uye kuoma kwesimbi yepamusoro-soro pakupisa kwekamuri (83 ~ 86HRA) zvakafanana.Kuomarara kukosha kwecemented carbide kunosiyana nehunhu, huwandu, saizi yechidimbu uye zvirimo zvesimbi yekubatanidza chikamu, uye kazhinji inodzikira nekuwedzera kwezviri mukati mechikamu chesimbi.Kuoma kweYT alloy kwakakwira kupfuura iyo yeYG alloy kana zviri mukati mechikamu chekubatanidza zvakafanana, uye alloy ine TaC(NbC) ine yakanyanya kuomarara tembiricha.
② Kupeta kusimba uye kusimba: simba rekukotama reinowanzo shandiswa simende carbide iri mukati me900 ~ 1500MPa.Iyo yakakwirira yezviri mukati mesimbi yekubatanidza chikamu, iyo inowedzera simba rekukombama.Kana zvinyorwa zvekunamatira zvakafanana, simba reYG (WC-Co) alloy rakakwirira kudarika yeYT (WC-TiC-Co) alloy, uye simba rinoderera nekuwedzera kweTiC content.Tungsten carbide ndeye brittle zvinhu, uye kukanganisa kwayo kusimba patembiricha yekamuri ingori 1/30 kusvika 1/8 yesimbi yekumhanya.
(3) Inowanzo shandiswa carbide chishandiso application
YG alloys anonyanya kushandiswa kugadzira simbi yakakandwa, isina-ferrous simbi uye isiri-simbi zvinhu.Fine-grain carbide (yakadai seYG3X, YG6X) muhuwandu hwakafanana hwecobalt pane kuomarara kwezviyo uye kusapfeka kupfeka kwakakwira, yakakodzera kugadzira imwe yakakosha simbi yakaoma, austenitic stainless simbi, kupisa-resistant alloy, titanium alloy, hard bronze. uye kupfeka-resistant insulation materials.
Mabhenefiti akatanhamara eYT class cemented carbide akanyanya kuomarara, akanaka kupisa kupisa, kuoma kwekushisa kwakanyanya uye kusimba kwesimba kupfuura YG kirasi, yakanaka oxidation kuramba.Naizvozvo, kana banga richidikanwa kuve nepamusoro kupisa kupisa uye kupfeka kuramba, mhando ine yakakwira TiC yemukati inofanirwa kusarudzwa.YT alloy yakakodzera kugadzira epurasitiki zvinhu sesimbi, asi isina kukodzera kugadzirisa titanium alloy, silicon aluminium alloy.
YW alloys ane zvimiro zveYG neYT alloys, uye ane yakanaka comprehensive properties.Inogona kushandiswa kugadzira simbi, simbi yakakandwa uye isina-ferrous simbi.Ma alloys akadaro, kana akawedzera zvakanaka cobalt zvemukati, anogona kuve akasimba kwazvo uye anogona kushandiswa kune hutsinye machining uye nepakati kucheka kwezvinhu zvakasiyana zvakaoma.
