Tungsten simbi: Chigadzirwa chakapedzwa chine inenge 18% tungsten alloy simbi. Tungsten simbi ndeye hard alloy, inozivikanwawo se tungsten-titanium alloy. Iko kuoma ndeye 10K Vickers, yechipiri chete kune diamond. Nekuda kweizvi, tungsten simbi zvigadzirwa (zvakajairika tungsten simbi wachi) zvine hunhu hwekusapfekwa nyore. Inowanzoshandiswa mumaturusi e-lathe, mabheti ekurovera, mabheti ekucheka magirazi, mabheti ekucheka. Iyo yakasimba uye haityi kuvharwa, asi ine brittle.
Cemented carbide: ndeyemunda wehupfu metallurgy. Cemented carbide, inozivikanwawo sesimbi ceramic, ndeye ceramic ine zvimwe zvinhu zvesimbi, iyo inogadzirwa nesimbi carbides (WC, TaC, TiC, NbC, etc.) kana simbi oxides (yakadai seAl2O3, ZrO2, nezvimwewo) sechikamu chikuru, uye huwandu hwakakodzera hwesimbi hupfu (Co, Cr, Mo, Ni, Fe kuburikidza, nezvimwewo) inowedzerwa. Cobalt (Co) inoshandiswa kuridza chisungo chekubatanidza mu alloy, ndiko kuti, panguva yekupisa, inogona kutenderedza tungsten carbide (WC) poda uye yakasimba chisungo pamwe chete. Mushure mekutonhora, inova simende carbide. (Maitiro acho akaenzana nesamende mukongiri). Zviri mukati kazhinji: 3% -30%. Tungsten carbide (WC) ndicho chikamu chikuru chinotarisa zvimwe zvesimbi zveiyi simende carbide kana cermet, inoverengera 70% -97% yezvikamu zvese (uremu reshiyo). Inoshandiswa zvakanyanya mukupfeka-inodzivirira, yakakwirira-inodzivirirwa, inodzivirira corrosion kana mapanga uye misoro yezvishandiso munzvimbo dzakaoma dzekushanda.
Tungsten simbi ndeye simende carbide, asi simende carbide haisati iri tungsten simbi. Mazuvano, vatengi muTaiwan uye Southeast Asia nyika vanofarira kushandisa izwi rekuti tungsten simbi. Kana iwe ukataura navo zvakadzama, uchaona kuti mazhinji acho achiri kutaura nezve simende carbide.
Musiyano uripo pakati petungsten simbi necemented carbide ndewekuti tungsten simbi, inozivikanwawo sesimbi yekumhanya-mhanya kana simbi yekushandisa, inogadzirwa nekuwedzera tungsten simbi se tungsten mbishi zvinhu kusimbi yakanyungudutswa uchishandisa simbi yekugadzira simbi, inozivikanwawo sesimbi yekumhanya-mhanya kana simbi yemidziyo, uye zvirimo zve tungsten zvinowanzoita 15-25%; nepo simende carbide inogadzirwa ne sintering tungsten carbide semuviri mukuru necobalt kana mamwe masimbi ekubatanidza uchishandisa poda metallurgy tekinoroji, uye tungsten yayo yemukati inowanzova pamusoro pe80%. Zvichitaurwa zviri nyore, chero chinhu chine kuomarara kunodarika HRC65 chero chiri alloy chinogona kunzi cemented carbide, uye tungsten simbi ingori mhando ye simende carbide ine kuoma pakati peHRC85 ne92, uye inowanzoshandiswa kugadzira mapanga.
