1. Argon atomization

Argon atomization ntụ ntụ bụ usoro na-eme ntụ ntụ nke na-agbaji mmiri ígwè ahụ n'ime ihe ndị dị mma site na ngwa ngwa nke argon gas ma tinyezie ya n'ime ntụ ntụ siri ike.

2. Plasma na-atụgharị electrode usoro

A maara plasma nke anọ dị ka ihe na plasma rotating electrode atomization method (PREP) usoro egwe ọka nwere ike kọwara dị ka ndị a: ígwè ma ọ bụ droplet atomized indoor inert gas (argon ma ọ bụ helium) esemokwu, na-agbajikwa n'okpuru alloy consumable electrode, na ike oriri nke oke na coaxial plasma arc okpomọkụ isi iyi gbazere n'okpuru ọrụ nke akpụkpọ ahụ mmiri, akpụkpọ anụ mmiri n'okpuru mmetụta nke ike centrifugal na-atụgharị nke etolite site na mmiri mmiri na-agba ọsọ dị elu, a wụrụ awụ omume nke shiee nrụgide, wee dobe n'okpuru mmetụta nke elu erughị ala, ngwa ngwa jụrụ solidification n'ime okirikiri nhọrọ ukwuu ntụ ntụ.

Anyị akpọtụrụla ọtụtụ powders metal nke enwere ike iji na mbipụta 3D, yabụ kedu ihe ntụ ntụ ígwè chọrọ iji mejuo ihe achọrọ nke mbipụta 3D?

1. Ịdị ọcha

Ihe ntinye nke seramiiki ga-ebelata arụmọrụ nke ngwaahịa ikpeazụ, na ntinye ndị a na-enwekarị ebe mgbaze dị elu, ọ na-esiri ike ịmegharị, n'ihi ya, a ghaghị inwe ntinye seramiiki na ntụ ntụ.

E wezụga nke ahụ, ọ dịkwa mkpa ka a chịkwaa ihe dị n'ime oxygen na nitrogen.

Ugbu a na-eji ígwè ntụ ntụ nkwadebe technology nke 3 d obibi tumadi atomization usoro, ntụ ntụ nwere nnukwu kpọmkwem n'elu ebe, eke oxidation, akpan akpan ngwa, dị ka aerospace ahịa index chọrọ ọzọ stringent, dị ka oxygen etoju na elu-okpomọkụ alloy ntụ ntụ. bụ 0.006% - 0.018%, oxygen ọdịnaya nke titanium alloy ntụ ntụ bụ 0.007% - 0.013%, igwe anaghị agba nchara ntụ ntụ oxygen ọdịnaya nke 0.010% ruo 0.025%.

2. Nkesa nke ntụ ntụ

Dị iche iche 3D ebipụta akụrụngwa na akpụ usoro nwere dị iche iche chọrọ na ntụ ntụ size nkesa. Ka ọ dị ugbu a, oke nha ntụ ntụ nke a na-ejikarị ebipụta ígwè 3D bụ 15-53 cm (ezigbo ntụ ntụ) na 53-105 cm (ụtụ ntụ ntụ), nke enwere ike ịgbatị ruo 105-150 cm (ụtụ ntụ ntụ) n'ọnọdụ ụfọdụ.

Nhọrọ nke metal ntụ ntụ urughuru size maka 3D obibi bụ tumadi kewara dị ka metal na-ebi akwụkwọ dị iche iche ike isi mmalite. The ngwa nbipute na laser dị ka ike isi iyi kwesịrị ekwesị maka iji 15-53 m ntụ ntụ dị ka consumable ihe n'ihi na nke mara mma na-elekwasị anya ntụpọ na mfe agbaze nke ezi ntụ ntụ. Site na ọkụ elektrọn dị ka isi iyi ike, ngwa nbipute uzuzu nwere ebe a na-elekwasị anya ntakịrị, nke dabara adaba maka uzuzu agbaze ma dabara adaba maka iji uzuzu nke 53-105 m. Maka ndị na-ebi akwụkwọ nri coaxial ntụ ntụ, ntụ ntụ nwere nha nha nke 105-150 m nwere ike iji dị ka ihe oriri.

3. Morphology nke ntụ ntụ

Ọdịdị nke ntụ ntụ nwere njikọ chiri anya na usoro nkwadebe nke uzuzu. N'ozuzu, mgbe gas ígwè ma ọ bụ mmiri a wụrụ awụ gbanwere ghọọ ụwa, ọdịdị nke ntụ ntụ na-emekarị ka ọ dị okirikiri. Mgbe a na-agbanwe ihe siri ike n'ime ala, ihe ndị na-emepụta ntụ ntụ na-abụkarị nke ọdịdị na-adịghị mma, ebe ntụ ntụ a kwadebere site na ngwọta electrolysis nke mmiri mmiri na-abụkarị dendritic.

N'ozuzu, nke dị elu nke sphericity, nke ka mma nke mmiri nke ntụ ntụ ntụ. A chọrọ spericity nke 3D ígwè ntụ ntụ e biri ebi karịa 98%, nke na-eme ka ọ dị mfe dina na zipu ntụ ntụ maka ibipụta.

Tebụl dị n'elu na-egosi morphology nke ntụ ntụ ígwè kwekọrọ na ụzọ nkwadebe ntụ ntụ dị iche iche. Enwere ike ịhụ na, ma e wezụga maka ikuku aerosol na usoro electrode na-atụgharị, ọdịdị nke powders nke a kwadebere site n'ụzọ ndị ọzọ abụghị nke gburugburu. Ya mere, aerosol na usoro eletrọd na-atụgharị bụ ụzọ nkwadebe bụ isi nke ntụ ntụ ígwè obibi akwụkwọ 3D dị elu.

4. Powder fluidity na rụrụ nkwa njupụta

Mmiri mmiri ntụ ntụ na-emetụta kpọmkwem ịdị n'otu nke mgbasa ntụ ntụ na nkwụsi ike nke nri ntụ ntụ na usoro mbipụta.

Ọkpụkpụ ahụ metụtara morphology ntụ ntụ, nkesa nha nha, yana njupụta nkwakọ ngwaahịa na-adịghị. The ibu na ntụ ntụ urughuru bụ, ndị ọzọ mgbe urughuru udi bụ, na nta nkezi nke ezi ntụ ntụ na urughuru size mejupụtara bụ, mma na fluidity bụ. Njupụta nke urughuru nọgidere na-agbanweghị, njupụta ndị ikwu na-abawanye, na uzuzu uzuzu mụbara. E wezụga nke ahụ, mgbasa nke mmiri na gas n'elu ihe ndị ahụ ga-ebelata mmiri nke ntụ ntụ.

O doro anya na njupụta ntụ ntụ sample bụ ndammana juputara akpa, unit olu nke ntụ ntụ àgwà, n'ozuzu, ndị ọzọ keadighi rarii ntụ ntụ urughuru size, na ibu ndị doro anya njupụta, ọkpụrụkpụ nke collocation ntụ ntụ nwere ike nweta elu pụtara njupụta, anya njupụta mmetụta na metal obibi njupụta nke ngwaahịa ikpeazụ ejighị n'aka, ma njupụta pụtara ìhè na-abawanye, nwere ike melite liquidity nke ntụ ntụ.

N'ime afọ ole na ole gara aga, China na-arụsi ọrụ ike nyochaa 3 d-ebi akwụkwọ metal powder technology na nwere ọtụtụ elu-egwe ọka ngwa ngwa. Mana, n'ozuzu, a ka nwere ọdịiche dị n'etiti ịkụcha teknụzụ n'ụlọ na ná mba ọzọ. Ụdị ntụ ntụ ntụ dị elu dị ugbu a na ngwá ọrụ mmepụta ihe ka na-adabere na mbubata, n'ịkwalite mbipụta 3 d nke obodo na nkà na ụzụ nkwadebe ntụ ntụ na mmepe nke China ka na-aga n'ihu.
