Gịnị bụ atomization nke agụụ metal ntụ ntụ?

N'ihe gbasara sayensị na nkà na ụzụ nke oge a, nkà na ụzụ nkwadebe nke ígwè powders na-emepe emepe mgbe niile. N'ime ha, teknụzụ ikuku metal powder atomization, dị ka usoro nkwadebe dị mkpa, nwere uru pụrụ iche na atụmanya ngwa sara mbara. Edemede a ga-abanye n'echiche nke vacuum metal powder atomization, gụnyere ụkpụrụ ya, ụzọ ya, njirimara ya, ngwa, na usoro mmepe n'ọdịnihu.

1. Nchịkọta nke Metal Powder Atomization Technology

Ígwè ntụ ntụ atomization bụ usoro nke ịtụgharị ọla a wụrụ awụ ka ọ bụrụ ezigbo ntụ ntụ. Site n'iji ngwa atomization kpọmkwem, a na-efesa ígwè mmiri mmiri n'ime obere ụmụ irighiri mmiri, nke na-esiwanye ike ngwa ngwa n'oge usoro jụrụ oyi na-etolite ntụ ntụ. Metal powder atomization technology nwere ike ịkwadebe dị iche iche metal powders na dị iche iche urughuru nha, shapes, na mejupụtara izute mkpa nke dị iche iche ubi.

Ngwa igwe ntụ ntụ atomizing

2, Ụkpụrụ nke agụụ metal ntụ ntụ atomization

Vacuum metal powder atomization bụ usoro nke igwe ntụ ntụ atomization nke emere na gburugburu oghere. Ụkpụrụ bụ isi bụ iji ikuku na-agba ọsọ dị elu, mmiri nrụgide dị elu, ma ọ bụ ike centrifugal iji gbasaa ígwè a wụrụ awụ n'ime obere ụmụ irighiri mmiri n'okpuru ọnọdụ oghere. N'ihi ọnụnọ nke oghere oghere, kọntaktị dị n'etiti ụmụ irighiri mmiri na ikuku nwere ike ibelata nke ọma, na-ezere oxidation na mmetọ, si otú ahụ na-emeziwanye ogo nke ntụ ntụ ígwè.

N'ime usoro atomization metal uzuzu agụụ, a na-ebu ụzọ kpoo ihe igwe ahụ ọkụ ka ọ bụrụ ọnọdụ mgbaze. Mgbe ahụ, site na oghere atomizing a kapịrị ọnụ, a na-efesa ígwè ahụ a wụrụ awụ n'ọsọ dị elu ma na-emekọrịta ihe na usoro atomizing (dị ka gas inert, mmiri nrụgide dị elu, wdg) iji mepụta obere ụmụ irighiri mmiri. Ụmụ irighiri mmiri ndị a na-ajụ oyi ngwa ngwa ma na-esiwanye ike na gburugburu oghere, n'ikpeazụ na-akpụ ntụ ntụ.

3. Usoro agụụ metal ntụ ntụ atomization

(1) Vacuum Inert Gas Atomization Method

Ụkpụrụ: A na-efesa ígwè a wụrụ awụ site n'obere oghere n'ebe a na-adịghị ahụ anya, a na-ejikwa gas na-adịghị arụ ọrụ (dị ka argon, nitrogen, wdg) na-emetụta ụda ígwè ahụ, na-efesa ya n'ime obere ụmụ irighiri mmiri. Gasị ndị na-adịghị agwụ agwụ na-ekere òkè n'ịjụjụ na ichebe ụmụ irighiri mmiri ígwè n'oge usoro atomization, na-egbochi oxidation na mmetọ.

Njirimara: Enwere ike ịkwado ịdị ọcha dị elu na ezigbo spericity metal powders, kwesịrị ekwesị maka ubi ndị na-achọ nnukwu ntụ ntụ, dị ka ikuku ikuku, ngwá electronic, wdg.

(2) Usoro atomization oghere

Ụkpụrụ: A na-efesa ígwè a wụrụ awụ site na nozulu n'ebe a na-adịghị ahụ anya, na mmiri na-agba ọsọ na-emetụta mmiri mmiri ígwè ahụ, na-efesa ya n'ime obere ụmụ irighiri mmiri. Mmiri na-ekere òkè n'ịjụjụ na imebi mmiri mmiri ígwè n'oge usoro atomization.

Njirimara: Ọ nwere ike ịkwadebe powders metal na mma urughuru size na ọnụ ala dị ala, ma ogo nke oxidation nke ntụ ntụ dịtụ elu na-achọ ụdi nhazi.

(3) Vacuum centrifugal atomization Usoro

Ụkpụrụ: Tinye ígwè a wụrụ awụ n'ime diski centrifugal ma ọ bụ crucible na-agba ọsọ dị elu, na n'okpuru ọrụ nke ike centrifugal, a na-atụba ígwè ahụ gbazere wee gbasasịa n'ime obere ụmụ irighiri mmiri. Mmụba mmiri na-adị jụụ ma na-esiwanye ike na gburugburu oghere, na-akpụ ntụ ntụ.

Atụmatụ: Ọ nwere ike ịkwadebe metal powders na elu spericity na edo urughuru size nkesa, adabara na-akwadebe elu-arụmọrụ metal ntụ ntụ ihe.

4, Njirimara nke Vacuum Metal Powder Atomization

① Ịdị ọcha dị elu

Ebe ikuku na-ekpo ọkụ nwere ike ibelata kọntaktị dị n'etiti ntụ ntụ na ikuku, zere oxidation na mmetọ, wee si otú ahụ meziwanye ịdị ọcha nke ntụ ntụ.

Maka ụfọdụ ihe igwe nwere oke ịdị ọcha chọrọ, dị ka alloys titanium, alloy okpomọkụ dị elu, wdg, teknụzụ atomization metal na-ekpo ọkụ bụ ụzọ nkwadebe dị mma.

②Ọdịiche dị mma

N'oge usoro nke agụụ metal ntụ ntụ atomization, ụmụ irighiri mmiri na-emekarị na-etolite spherical shapes n'okpuru omume nke elu erughị ala, na-akpata ezi sphericity nke njikere metal ntụ ntụ.

Ihe ntụ ntụ Spherical nwere ezigbo ịgbapụta, ikike njuputa, na mkpakọ, nke bara uru maka imeziwanye ogo na arụmọrụ nke ngwaahịa metallurgy ntụ ntụ.

③Uniform urughuru nha nkesa

Site ukpụhọde atomization parameters, urughuru size nkesa nke metal ntụ ntụ nwere ike ịchịkwa na-eme ka ọ ọzọ edo.

Uniform urughuru size nkesa nwere ike melite sintering na n'ibu Njirimara nke powders, na ibelata scrap ọnụego nke ngwaahịa.

④ Ngwakọta kemịkalụ n'otu

A na-agbaze ọla a wụrụ awụ n'ime oghere oghere, na-eme ka ụmụ irighiri mmiri dị ngwa ngwa na ịdị n'otu kemịkalụ dị mma.

Nke a dị oke mkpa maka ụfọdụ ihe igwe nwere ihe mejupụtara kemịkalụ siri ike, dị ka alloys arụ ọrụ dị elu, nchara pụrụ iche, wdg.

5. Ngwa nke Vacuum Metal Powder Atomization
