Cemented carbide yakagadzirwa nekuomarara kwepamusoro, refractory metal carbide (yakadai seWC, TiC, TaC, NbC, zvichingodaro) pamwe nemabhainda esimbi (akadai secobalt, nickel, nezvimwewo) kuburikidza nehupfu metallurgy process, parizvino ndiyo isimba repamusoro pasi rose. alloy, nehupamhi hwekuoma (89 ~ 93Hm), simba rakakwirira, kunaka kunopisa kuoma uye mamwe maitiro.Nokudaro, inoshandiswa zvakanyanya mukugadzira mabheti ekuongorora drill, molds uye zvishandiso.Nekuenderera mberi kwekuvandudza tekinoroji yekucheka munzira yekumhanya uye yakanyanya kurongeka, kuomarara, kusagadzika kwekusapfeka, kugaya chaiko uye kucheka kumucheto kwemhando yecemented carbide maturusi anodiwa kuti awedzere uye akakwira.Ukuru hwezviyo zvesimende carbide zvakare zvishoma nezvishoma kubva kune yekutanga-yakaomeswa-yakaomeswa uye yepakati-yakaomeswa kusvika kune yakanaka-grained, ultra-yakanaka-grained uye nanocrystal-grained.
Parizvino, coarse-grained cemented carbide inoshandiswa zvakanyanya mu geological and mineral tools, stamping inofa, kuchera mafuta, sando huru dzepamusoro dzekugadzirwa kwedhaimondi yekugadzira, jet injini zvikamu nemimwe minda;fine-grained uye ultra-fine-grained cemented carbide ine hunhu hwekuoma kwepamusoro uye kusimba kwepamusoro, inonyanya kushandiswa kugadzira yakasimba carbide zvishandiso, indexable inoisa uye micro drills.
Nekukwenenzverwa kwezviyo zveWC mune simende carbide, zvimisikidzo zvakaita sekuoma uye simba zvakawedzera, ukuwo zvimiro zvakaita sekuomarara kwekutsemuka kwakadzikira, uye kuita kwekugaya kwakadai sekuramba kupfeka kwakachinjawo.
Zviyo zvitatu zvakasiyana saizi yedhaimondi resin bond yekukuya mavhiri anoshandiswa kuita bvunzo dzekukuya pasi pemamwe mamiriro ekukuya matatu ane simende carbides ane akasiyana saizi yezviyo: yakaomarara, yakanaka uye yakanyanya kunaka.Kuburikidza nekuyerwa kwesimba rekutenderera, vhiri rekukuya uye kurasikirwa kwechishandiso, uye machining kushata kwepamusoro peguyo panguva yekukuya, pesvedzero yekuchinja saizi yezviyo yeWC mune simende carbide pakukuya uye kuita senge simba rekukuya, kugaya reshiyo, uye kushata kwepamusoro kunoongororwa.
Kuburikidza nemuyedzo, zvinogona kuzivikanwa kuti pasi pemamiriro ezvinhu, kukuya maparamendi emuguyo wepamusoro akafanana, simba rekukuya uye simba rekukuya rinopedzwa nekukuya-grained cemented carbide yakakura kupfuura iyo yakacheneswa uye yakanyanya kunaka. -grained, uye simba rekukuya pamusoro peguyo rinowedzera nekukwira kwekukura kwezviyo.Kukuya reshiyo ye-ultra-fine cemented carbide inowedzera nekukwira kwekukura kwezviyo, zvichiratidza kuti kusapfeka kwerudzi urwu rwesimende carbide kunodzikira nekuwedzera kwekukura kwezviyo, uye kushata kwepamusoro kwerudzi urwu rwesimende carbide mushure mekukuya zvakanaka pasi. iwowo mamiriro ekukuya anoderera nekuwedzera kwekukura kwezviyo.
Kushandisa madhaimondi ekukuya vhiri ndiyo nzira huru yekugadzira simende maturusi ecarbide, kugaya kwepasi kune chekuita kwakakosha pakucheka kuita uye hupenyu hwebasa rematurusi esimende, uye maparamendi ekugaya ndizvo zvinhu zvikuru zvakakanganisa kushata kwepasi. simende carbide
Iyo WC-Co cemented carbide specimen yakaedzwa mukukuya pamushini wekukuya pamusoro, uye sampuli yacho yaive yekupedzisira-yakachena-grained simende carbide yakasimwa neHIP tekinoroji.
Pakudzika kwakafanana, kushata kwekukuya kwechiso chemuenzaniso kwakawedzera nekukwira kwechikamu chekukura kwegumbo.Kuenzaniswa ne150# vhiri rekukuya, kushata kwepamusoro kwemuenzaniso wekukuya kunosiyana-siyana kana uchikuya ne 280# vhiri rekukuya, uku kushata kwepamusoro kunochinja zvakanyanya kana uchikuya neW20 vhiri.
