Usoro nke Sintering Tungsten Carbide

Dị ka anyị niile maara, tungsten carbide bụ otu n'ime ihe ndị siri ike etinyere na ụlọ ọrụ ọgbara ọhụrụ. Iji mee mmepụta carbide tungsten, ọ ga-ahụrịrị usoro dị iche iche nke ụlọ ọrụ mmepụta ihe, dị ka ịgwakọta ntụ ntụ, igwe igwe mmiri, ihicha mmiri, ịpị, sintering, na nlele mma. N'oge nkwụsịtụ, olu nke carbide cimented ga-ebelata site na ọkara. Isiokwu a bụ iji chọpụta ihe mere tungsten carbide n'oge sintering.

N'oge sintering, enwere usoro anọ nke tungsten carbide ga-enwetarịrị. Ha bụ:

1. Mwepụ nke onye na-akpụzi ihe na ogbo tupu ọkụ;

2. Ogbo sintering siri ike;

3. Liquid-phase sintering ogbo;

4. Ogbo oyi.

1. Mwepụ nke onye na-akpụzi ihe na ogbo tupu ọkụ;

Na usoro a, okpomọkụ kwesịrị ịbawanye nwayọọ nwayọọ, na nke a ogbo mere n'okpuru 1800 ℃. Ka okpomọkụ na-abawanye, mmiri, gas, na ihe mgbaze dị na tungsten carbide a na-etinye n'ọrụ na-eji nwayọọ nwayọọ na-ekpochapụ. Onye na-akpụzi ihe ga-eme ka ọdịnaya carbon nke carbide simented na-eme ka ọ dịkwuo elu. Na sintering dị iche iche, mmụba nke ọdịnaya carbide dị iche. A na-ewepụkwa nrụgide kọntaktị n'etiti ihe ndị dị na ntụ ntụ n'oge mmụba nke okpomọkụ.

2. Ogbo sintering siri ike

Ka okpomọkụ na-eji nwayọọ nwayọọ na-amụba, singing na-aga n'ihu. Nke a ogbo pụtara n'etiti 1800 ℃ na eutectic okpomọkụ. Ihe a na-akpọ eutectic okpomọkụ na-ezo aka na okpomọkụ kachasị ala nke mmiri mmiri nwere ike ịdị na usoro a. Ogbo a ga-aga n'ihu dabere na ogbo ikpeazụ. Ngwunye rọba na-abawanye na ahụ nke emebi emebi na-agbada nke ukwuu. N'oge a, olu tungsten carbide na-ebelata n'ụzọ doro anya.

3. Liquid frasi sintering ogbo

N'oge a, okpomọkụ na-ebili ruo mgbe ọ na-erute okpomọkụ kachasị elu na usoro nsị, okpomọkụ na-ekpo ọkụ. Mgbe usoro mmiri mmiri pụtara na tungsten carbide, mbelata na-agwụ ngwa ngwa. N'ihi esemokwu dị n'elu nke mmiri mmiri, ihe ndị na-emepụta ntụ ntụ na-abịakwute ibe ha, na pores dị na ihe ndị ahụ na-eji nwayọọ nwayọọ jupụta na mmiri mmiri.

4. Ogbo oyi

Mgbe emechara, a na-ewepụ carbide ciment na ọkụ ọkụ ma mee ka ọ dị jụụ n'ime ụlọ. Ụfọdụ ụlọ ọrụ ga-eji ikpo ọkụ na-ekpofu ọkụ n'ime ọkụ na-ekpo ọkụ maka ojiji ọkụ ọhụrụ. N'ebe a, ka okpomọkụ na-adaba, a na-emepụta microstructure ikpeazụ nke alloy.

Sintering bụ usoro siri ike, na zzbetter nwere ike inye gị carbide tungsten dị elu. 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.
