I-Cobalt kunqubo ye-Cemented Carbide

Namuhla, ngenxa yokuthi i-carbide enosimende inokuqina okuphezulu, ukumelana nokugqoka, kanye ne-elastic modulus, amathuluzi e-carbide enosimende adlala indima ebalulekile uma ufuna izinto zesimanje zamathuluzi, izinto ezithwala ukugqokwa, izinto ezisezingeni eliphezulu, nezinto ezimelana nokugqwala. Njengoba i-Co inokumanzisa okuhle nokunamathela ku-WC ne-TiC, isetshenziswa kabanzi njenge-ejenti yokunamathela embonini njengethuluzi lokusika. Ukusebenzisa i-Co njenge-ejenti yokunamathela kwenza i-carbide enosimende ibe izinzuzo zamandla aphezulu, ubulukhuni obuphezulu, nokumelana nokugqoka okuphezulu.

Kodwa-ke, ngenxa yentengo ephezulu yensimbi ye-cobalt kanye nokushoda kwezinsiza, abantu bebelokhu befuna ezinye esikhundleni sensimbi ye-cobalt. Izinto ezisetshenziswayo ezivamile manje yi-nickel ne-ayoni. Ngeshwa, ukusebenzisa i-iron powder njenge-adhesion adhesion ngokuvamile kunamandla aphansi emishini. Ukusebenzisa i-nickel ehlanzekile njenge-ejenti yokunamathela ye-carbide ebonakalayo neyomshini ye-carbide enosimende akulungile njengalabo abasebenzisa i-cobalt njenge-ejenti yokunamathela. Ukulawula inqubo nakho kunzima uma usebenzisa i-nickel ehlanzekile njenge-adhesion adhesion.

Indima ye-cobalt ku-carbide enosimende injengensimbi yokunamathela. I-Cobalt ingaba nomthelela ekuqina kwe-carbide enosimende ngokusebenzisa ikhono layo lokuguquguquka kwepulasitiki ekamelweni lokushisa. I-carbide enosimende yenziwa ngenqubo yokucwilisa. I-cobalt ne-nickel iba i-adhesion adhesion yendawo yonke ye-carbide enosimende. I-Cobalt inomthelela obalulekile ekukhiqizweni kwe-carbide kasimende, futhi cishe amaphesenti angama-90 ama-carbide anosimende asebenzisa i-cobalt njenge-adhesion adhesion.

I-carbide enosimende yakhiwe ngama-carbides aqinile kanye nezinsimbi ezithambile zokunamathela. I-Carbide inikeza ikhono lokumelana nomthwalo nokugqoka ukumelana ne-alloy, futhi i-ejenti yokunamathela inikeza ikhono lokukhubazeka ngokwepulasitiki ekamelweni lokushisa. Ukuqina komthelela kwe-carbide. Ukuqinisekisa ukuthi imikhiqizo ene-sintered isesimweni esihle, ama-adhesion agents adlala indima ebalulekile ekumanziseni i-carbide enosimende.

Uchungechunge lwe-tungsten-cobalt carbides lusetshenziselwa ukusika amathiphu wamathuluzi nemishini yezimayini edinga ukusebenza ezindaweni ezinobulukhuni obuphezulu. Ezinye izinsimbi zokuhlinza ezihlala isikhathi eside nomazibuthe unomphela nazo zenziwe ngama-cobalt alloys.

I-ductility kanye nokuqina kwemikhiqizo ye-carbide enosimende inganikezwa i-ejenti yokunamathela. Ngasikhathi sinye, i-ejenti yokunamathela inikeza amandla e-carbide enosimende encibilika kakhulu ingenziwa izingxenye ezingeni lokushisa elikude kakhulu ngaphansi kwendawo yokuncibilika.

I-ejenti yokunamathela engcono kakhulu kufanele ikwazi ukumanzisa ngokuphelele indawo ephezulu yokuncibilika ye-carbide enosimende. I-ayoni, i-cobalt, ne-nickel konke kungahlangabezana nezidingo ze-ejenti yokunamathela enhle.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
