Iyo tungsten yesimbi, ine zita rinobva kuSweden - tung (inorema) uye sten (dombo) inonyanya kushandiswa muchimiro chesimende tungsten carbides.Cemented carbides kana masimbi akaomarara sezvaanowanzo kunzi ikirasi yezvigadzirwa zvakagadzirwa ne'sementing' tsanga dzetungsten carbide mune binder matrix yesimbi cobalt nemaitiro anonzi liquid phase sintering.
Nhasi tungsten carbide saizi yezviyo inosiyana kubva pa 0.5 microns kusvika kune anopfuura 5 micron ine cobalt yemukati inogona kukwira kusvika kunosvika makumi matatu muzana nehuremu.Uye zvakare, kuwedzera mamwe carbides anogona zvakare kusiyanisa ekupedzisira zvivakwa.
Mhedzisiro ikirasi yezvinhu zvinoratidzirwa ne
Simba repamusoro
Kuoma
High kuoma
Nekusiyanisa saizi yezviyo zve tungsten carbide uye cobalt zvirimo mumatrix, uye nekuwedzera zvimwe zvinhu, mainjiniya vanogona kuwana kirasi yezvinhu izvo zvivakwa zvinogona kugadziridzwa kune akasiyana einjiniya application.Izvi zvinosanganisira maturusi epamusoro-soro, zvipfeko zvekupfeka uye maturusi emugodhi wekuvaka uye chikamu chemafuta negesi.
Zvigadzirwa zveTungsten Carbide mhedzisiro yehupfu simbi yehupfu iyo inonyanya kushandisa tungsten carbide uye cobalt simbi hupfu.Kazhinji, kuumbwa kwemusanganiswa kuchabva pa4% cobalt kusvika ku30% cobalt.
Chikonzero chikuru chekusarudza kushandisa tungsten carbide kutora mukana wekuomarara kwepamusoro kunoratidzwa nezvinhu izvi nekudaro kudzoreredza mwero wekupfeka wezvikamu zvega.Nehurombo, chirango chakasungirirwa pakuomarara kwakanyanya kushaikwa kwekuomarara kana simba.Neraki, nekusarudza zvinyorwa zvine yakakwira cobalt zvirimo, simba rinogona kuwanikwa pamwe nekuoma.
Sarudza yakaderera cobalt zvemukati zvekushandisa uko iyo chikamu chisingazotarisirwe kusangana nemhedzisiro, zadzisa kuomarara kwepamusoro, kupfeka kwakanyanya kuramba.
Sarudza yakakwira cobalt yemukati kana application ichisanganisira kuvhunduka kana kukanganisa uye kuwana yakakura kupfeka kuramba kupfuura zvimwe zvinhu zvakawanda zvinogona kupa, zvakasanganiswa nekugona kuramba kukuvara.
