Li-blades tsa Tungsten Carbide
Ka khetho e nepahetseng ea maemo, li-blades tsa tungsten carbide tsa boholo ba lijo-thollo tsa submicron li ka chorisoa ho isa moeling oa lehare ntle le bofokoli ba tlhaho bo atisang ho amahanngoa le carbide e tloaelehileng. Le hoja e sa sebetsane le ho tsieleha joaloka tšepe, carbide e sebetsa ka mokhoa o feteletseng, 'me e thata ho lekana le Rc 75-80. Bophelo ba lehare ba bonyane litšepe tse tloaelehileng tsa 50X li ka lebelloa haeba ho qojoa le ho robeha.
Joalo ka ha ho khethoa litšepe, ho khetha mofuta o motle oa tungsten carbide (WC) ke ts'ebetso e rarahaneng e kenyelletsang likhetho tse sekiselitsoeng lipakeng tsa ho hana ho roala le ho tiea / ho hanyetsa ho ts'oha. Tungsten carbide e entsoeng ka samente e entsoe ka sintering (ka mocheso o phahameng) motsoako oa tungsten carbide phofo e nang le phofo ea cobalt (Co), tšepe ea ductile e sebetsang e le "binder" bakeng sa likaroloana tse thata haholo tsa tungsten carbide. Mocheso oa ts'ebetso ea sintering ha o akarelletse karabelo ea likarolo tsa 2, empa ho e-na le hoo o etsa hore cobalt e fihle sebakeng se haufi le metsi 'me e be joaloka encapsulating glue matrix bakeng sa likaroloana tsa WC (tse sa angoeng ke mocheso). Mekhahlelo e 'meli, e leng karo-karolelano ea Cobalt ho WC le boholo ba karoloana ea WC, e laola haholo thepa e ngata ea sekotoana sa "cemented tungsten carbide".
Ho hlakisa boholo ba karolo e kholo ea WC le liperesente tse phahameng tsa Cobalt ho tla fana ka karolo e hanyetsanang le ts'oenyeho e matla (le e matla haholo). Ha boholo ba lijo-thollo tsa WC bo le betere (ka hona, sebaka se seholo sa WC se tlamehang ho tlotsoa ka Cobalt) le ha Cobalt e sa sebelisoe, karolo e hlahisoang e tla ba thata le ho feta. Ho fumana ts'ebetso e ntle ka ho fetisisa ho tsoa ho carbide joalo ka thepa ea lehare, ho bohlokoa ho qoba liphoso tsa pele ho nako tse bakiloeng ke ho phunya kapa ho robeha, ha ka nako e ts'oanang o netefatsa khanyetso e ntle ea ho apara.
Joalo ka taba e sebetsang, tlhahiso ea likhahla tse hlabang haholo, tse nang le li-angles tse thata li laela hore ho sebelisoe carbide e nang le thollo e ntle ha ho sebelisoa lehare (ho thibela li-nicks tse kholo le mapheo a makukuno). Ho fanoe ka tšebeliso ea carbide e nang le boholo ba lijo-thollo tsa 1 micron kapa ka tlase, ts'ebetso ea lehare la carbide; ka hona, e susumetsoa haholo ke % ea Cobalt le geometry ea bohale e boletsoeng. Lisebelisoa tsa ho itšeha tse kenyelletsang meroalo e leka-lekaneng ho isa ho e phahameng li sebetsanoa hantle ka ho hlakisa 12-15% ea Cobalt le geometry e nang le moeli o kenyellelitsoeng oa hoo e ka bang 40º. Likopo tse kenyelletsang meroalo e bobebe le ho lefa bophelo bo bolelele ba lehare ke batho ba loketseng carbide e nang le liperesente tse 6-9 tsa cobalt mme e kenyellelitsoe lehlakoreng la 30-35º.
HUAXIN CARBIDE e ikemiselitse ho u thusa ho fihlela tekanyo e nepahetseng ea thepa e tla u lumella ho fumana ts'ebetso e phahameng ho tsoa ho li-blade tsa hau tsa carbide.
HUAXIN CARBIDE e fana ka khetho ea mahare a betliloeng a carbide
