Izigaba ezine eziphambili zeTungsten Carbide Heat Treatment

I-tungsten carbide inokusebenza okuphezulu kunye neempawu ezibalaseleyo zoomatshini kunye nezomzimba, kubandakanya ukumelana nokunxiba okuphezulu, ukumelana nokugqwala, amandla okugoba, amandla e-torsion, njl., isetyenziselwa ukusika izixhobo, ukubumba okubandayo, iinxalenye zokunxiba, njl. njl. Eli nqaku likwazisa ngokufutshane ezine izigaba eziphambili ze-tungsten carbide unyango lokushisa, olunokuphucula iimpawu zomzimba kunye nomatshini we-alloy enzima.

Inkqubo yokunyanga ukushisa kwe-tungsten carbide inokwahlulwa ibe ngamanyathelo amane aphambili.

1. Ukususwa kwezinto zokubumba kunye ne-pre-sintering

Kwinqanaba lokuqala lokuntywila, iarhente yokubumba ibola ngokuthe ngcembe okanye ikhuphe umphunga, ngaphandle komzimba osikiweyo, kwangaxeshanye, iiarhente ezenza i-carburize i-sintering, kwaye inani lekhabhoni liya kwahluka ngokuxhomekeke kuhlobo, isixa, kunye nenkqubo yokucoca. . I-powder surface oxide iyancitshiswa, kwaye i-hydrogen inokunciphisa i-cobalt kunye ne-tungsten oxides kubushushu be-sintering. Ngempendulo ebuthathaka phakathi kwekhabhoni kunye ne-oxygen, uxinzelelo loqhagamshelwano phakathi kweengqungquthela ze powder lususwa ngokuthe ngcembe. I-powder yensimbi edibeneyo iqala ukuphendula kwaye i-recrystallization kunye nokusabalalisa komhlaba kuqala ukwenzeka. Amandla ebhlokhi anyukile.

2. Inqanaba le-slid-phase sintering (800°C - ubushushu be-eutectic)

Ubukho besigaba se-liquid, ngaphezu kwenkqubo yokuqhubeka nesigaba sangaphambili, ukuphendulwa kwesigaba esiqinileyo kunye nokusabalalisa kugxininisekile ngokunyuka kweplastiki ehamba phambili, kwaye i-shrinkage ecacileyo ibonakala kumzimba we-sintered.

3. Inqanaba le-liquid-phase sintering (ubushushu be-eutectic - ubushushu be-sintering)

Xa isigaba solwelo somzimba we-sintered senzeka, ukunyanzeliswa kugqitywe ngokukhawuleza, kwaye emva koko kwenzeka utshintsho lwe-crystallization. Umbutho osisiseko kunye nesakhiwo se-carbide senziwe.

4. Inqanaba lokupholisa (ubushushu be-sintering - ubushushu begumbi)

Ngeli nqanaba, amacandelo ombutho kunye nesigaba se-tungsten carbide afumana utshintsho oluthile phantsi kweemeko ezahlukeneyo zokupholisa, okwenza kube lula ukusebenzisa le mpawu; unyango olushushu lwe-alloy enzima luya kuphucula iimpawu zalo zomzimba kunye noomatshini.

I-ZZBETTER izinikele ekuveliseni umgangatho wehlabathi kunye neemveliso ze-tungsten carbide ezikumgangatho ophezulu. Iimveliso zethu zithengiswe kumazwe amaninzi nakwiindawo kwaye zenza impumelelo enkulu kwimarike yasekhaya.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
