Impahla ebonakalayo ye-tungsten carbide

Ubuchwepheshe besimanje bunohlu olubanzi lokusebenziseka kwe-alloy eyingqayizivele i-tungsten-cobalt. Kungani idume kangaka? Nazi ezinyeizakhiwo zomzimba i-tungsten carbide. Ngemva kokufunda lesi siqephu uzokwazi imininingwane eyengeziwe ngaso.

Ukuqina.

Sonke siyazi ukuthi idayimane ingenye yezinto zemvelo ezinzima kunazo zonke emhlabeni. Ngenkathi ubulukhuni be-tungsten carbide bungokwesibili kunedayimane.Ukuqina kungenye yezinto eziyinhloko zemishini ye-carbide enosimende. Ngokukhula kokuqukethwe kwe-cobalt ku-alloy noma ukwanda kosayizi wokusanhlamvu kwe-carbide, ubulukhuni be-alloy buyancipha. Isibonelo, lapho okuqukethwe kwe-cobalt ye-WC-Co yezimboni kukhuphuka kusuka ku-2% kuya ku-25%, ubulukhuni be-alloy buyancipha busuka ku-93 kuya cishe ku-86. Kuwo wonke ukwanda kwe-cobalt ngo-3%, ubulukhuni be-alloy buyancipha nge-1 degree. Ukucwenga usayizi wokusanhlamvu we-tungsten carbide kungathuthukisa ngempumelelo ubulukhuni be-alloy.

Amandla okugoba.

Njengobulukhuni, amandla okugoba angenye yezinto eziyinhloko ze-carbide enosimende. Kunezici eziningi eziyinkimbinkimbi ezithinta amandla okugoba we-alloy, Ngokuvamile, amandla okugoba we-alloy anda ngokwanda kokuqukethwe kwe-cobalt. Kodwa-ke, lapho okuqukethwe kwe-cobalt kudlula i-25%, amandla okugoba ayancipha ngokwanda kokuqukethwe kwe-cobalt. Ngokuqondene ne-WC-Co alloy yezimboni, amandla okugoba engxubevange ahlala enyuka ngokunyuka kokuqukethwe kwe-cobalt ku-0-25%.

Amandla acindezelayo.

Amandla acindezelayo e-carbide enosimende akhombisa amandla okumelana nomthwalo wokucindezela.Ngokukhula kwe-cobaltokuqukethwe futhi kukhuphuka ngosayizi wokusanhlamvu wesigaba se-tungsten carbide ku-alloy tamandla acindezelayo we-WC-Co alloy ayancipha. Ngakho-ke, i-fine-grain alloy enokuqukethwe kwe-cobalt ephansi inamandla okucindezela aphezulu.

Ukuqina komthelela.

Ukuqina komthelela kuyinkomba yezobuchwepheshe ebalulekile yengxubevange yezimayini, futhi inokubaluleka okusebenzayo kumathuluzi okusika ngezikhathi ezithile ngaphansi kwezimo ezinzima. Ukuqina komthelela we-WC-Co alloy kukhuphuka ngokwanda kokuqukethwe kwe-cobalt kanye nosayizi wezinhlamvu ze-tungsten carbide. Ngakho-ke, ama-alloys amaningi ezimayini angama-coarse-grained alloys ane-cobalt ephezulu.

Ukugcwala kwamagnetic. 

TI-magnetic induction intensity ye-alloy iyanda ngokukhula kwendawo yangaphandle kazibuthe. lapho amandla kazibuthe afinyelela inani elithile, amandla kazibuthe wokungeniswa akusakhuphuki, okungukuthi, i-alloy isifinyelele ukugcwaliswa kazibuthe. Inani lokugcwaliswa kazibuthe le-alloy lihlobene kuphela nokuqukethwe kwe-cobalt ku-alloy. Ngakho-ke, ukugcwaliswa kazibuthe kungasetshenziswa ukuhlola ukwakheka okungabhubhisi kwe-alloy noma ukukhomba ukuthi kukhona yini isigaba esingesona samagnetic η l ku-alloy enokwakheka okwaziwayo.

I-Elastic module.

NgobaWCine-elastic modulus ephezulu,Ngakho keI-WC-Co. I-elastic modulus iyancipha ngokunyuka kokuqukethwe kwe-cobalt ku-alloy, futhi usayizi wokusanhlamvu we-tungsten carbide ku-alloy awunawo umphumela osobala ku-modulus elastic.Wngokukhuphuka kwezinga lokushisa lesevisi ti-elastic modulus ye-alloy iyancipha.

I-coefficient yokwandisa ukushisa.

I-linear extension coefficient ye-WC-Co alloy iyanda ngokunyuka kokuqukethwe kwe-cobalt. Kodwa-ke, i-coefficient yokwandisa ye-alloy iphansi kakhulu kuneyensimbi, okuzobangela ukucindezela okukhulu kwe-welding lapho ithuluzi le-alloy lifakwe futhi lishiselwe. Uma izinyathelo zokupholisa kancane zingathathwa, ingxubevange izovame ukuqhekeka.

Sekukonke, i-Tungsten carbide inokusebenza okuphezulu ezindaweni zayo zomzimba. Ngenxa yalokho, uTIzakhiwo ezibonakalayo ze-carbide enosimende azikhawulelwelabo. Tizici zezinto ezinokwakheka okuhlukile kokusetshenziswa okuthile nazo zizohluka. Bengifuna ukwazi okwengeziwe mayelana ne-tungsten carbide wamukelekile ukusilandela.
