Mgbochi nke ngwaahịa Tungsten Carbide

Vacuum sintering pụtara na ntụ ntụ, ntụ ntụ, ma ọ bụ ụdị ihe ndị ọzọ na-ekpo ọkụ na okpomọkụ kwesịrị ekwesị na gburugburu oghere iji nweta njikọ dị n'etiti ụmụ irighiri ihe site na mbugharị atomic. Sintering bụ ime porous ntụ ntụ compacts nwere alloys nwere ụfọdụ ihe owuwu na Njirimara.

Cimemented carbide vacuum sintering bụ usoro nke sintering n'okpuru 101325Pa. Ịgbagharị n'okpuru ọnọdụ oghere na-ebelata mmetụta mgbochi nke gas na-ekpo ọkụ na elu ntụ ntụ na gas na pores mechiri emechi na densification. Sintering bara uru na usoro mgbasa ozi na densification ma nwee ike izere mmeghachi omume n'etiti ígwè na ụfọdụ ihe dị na mbara igwe n'oge usoro nsị. N'ụzọ dị ịrịba ama kwalite udu mmiri-ikike nke mmiri mmiri na-ekekọta oge na ike metal agba, ma agụụ sintering kwesịrị ịṅa ntị iji gbochie evaporation ọnwụ nke cobalt.

Enwere ike kewaa ikuku carbide cemented na nkeji anọ. Enwere ogbo mwepụ nke plasticizer, ogbo a na-ebute ụzọ, ikpo ọkụ dị elu na ọkwa jụrụ oyi.

Uru nke vacuum sintering nke cemented carbide bụ:

1. Belata mmetọ nke ngwaahịa ndị ikuku na-emerụ ahụ na-akpata na gburugburu ebe obibi. Dị ka ihe atụ, ọ na-esi nnọọ ike iru ebe igirigi nke mwepu 40 ℃ maka mmiri ọdịnaya nke hydrogen eme site electrolysis, ma ọ bụghị ihe siri ike inweta dị otú ahụ a ogo nke agụụ;

2. Vacuum bụ gas inert kachasị mma. Mgbe ikuku ndị ọzọ na-eweghachi na inert adịghị adabara, ma ọ bụ maka ihe ndị na-adịkarị mfe decarburization na carburization, enwere ike iji ihe na-ekpo ọkụ mee ihe;

3. Vacuum nwere ike imeziwanye ikike mmiri nke mmiri mmiri na-agba ọsọ, nke bara uru na-ebelata ma melite nhazi nke carbide cimented;

4. Vacuum na-enyere aka iwepụ ihe ndị na-adịghị ọcha ma ọ bụ oxides dị ka Si, Al, Mg, na-eme ka ihe dị ọcha;

5. Vacuum bara uru iji belata adsorbed gas (gas fọdụrụ na pores na mmeghachi omume gas ngwaahịa) ma nwee mmetụta doro anya na ịkwalite shrinkage na njedebe ikpeazụ nke sintering.

Site n'echiche akụ na ụba, ọ bụ ezie na akụrụngwa sintering na-ekpo ọkụ nwere nnukwu ego na mmepụta dị ala kwa ọkụ, ike oriri dị ala, ya mere ọnụ ahịa nke ịnọgide na-enwe oghere dị nnọọ ala karịa ọnụahịa nke ebe nkwadebe. N'ime oge mmiri mmiri nke sintering n'okpuru oghere, mfu volatilization nke metal binder bụkwa ihe dị mkpa, nke ọ bụghị naanị na-agbanwe ma na-emetụta nhazi ikpeazụ na nhazi nke alloy kamakwa na-egbochi usoro nkwụsị ahụ n'onwe ya.

Mmepụta carbide cimented bụ usoro siri ike. ZZBETTER na-eji nkọwapụta mmepụta ọ bụla akpọrọ ihe, na-achịkwa nke ọma ngwaahịa carbide cimented ma na-enye ihe ngwọta maka ọnọdụ ọrụ siri ike.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi na nkọwa ndị ọzọ, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala ibe.
