Kudiwa kwesimbi poda kwakawedzera mumakore achangopfuura, zvichifambiswa nekufambira mberi mukugadzirwa kwekuwedzera, aerospace, mota uye mamwe maindasitiri. Metal poda yakakosha pakuita senge 3D kudhinda, sintering uye poda metallurgy. Imwe yedzakanyanya hunyanzvi nzira dzekugadzira hupfu uhwu ndeye simbi yehupfu atomization, maitiro anoshandura simbi yakanyungudutswa kuita zvidimbu zvinyoro. Ichi chinyorwa chinoongorora kuti simbi inoshandurwa sei kuita hupfu, ichitarisa pane basa rehupfu atomization midziyo mune iyi yakakosha kugadzira maitiro.

Nzwisisa metal powder atomization

Metal powder atomization inzira inoshandura simbi yakanyungudutswa kuita zvidimbu zvidimbu zvehupfu. Iyo tekinoroji inofarirwa nekugona kwayo kugadzira poda ine yunifomu particle size, chimiro uye kugovera, izvo zvakakosha kune akasiyana maapplication. Iyo atomization process inogona kukamurwa kuita maviri makuru marudzi: gasi atomization uye mvura atomization.

Gasi atomization

Mugasi atomization, simbi yakanyungudutswa inodururwa kuburikidza nemuromo uye atomize nepamusoro-velocity gasi rukova, kazhinji nitrogen kana argon. Kukurumidza kutonhora kwemadonhwe akanyunguduka kunoguma nekuumbwa kwesimbi yakasimba. Iyi nzira inonyanya kushanda pakugadzira hupfu hwepamusoro-soro nekuti gasi inert inoderedza oxidation uye kusvibiswa.

Mvura atomization

Atomization yemvura, kune rumwe rutivi, inoshandisa majeti emvura ane simba guru kuputsa simbi yakanyunguduka kuita madonhwe. Iyi nzira inowanzoita mari yakawanda uye inogona kuburitsa huwandu hukuru hwehupfu. Nekudaro, inogona kukonzera imwe oxidation, iyo inogona kukanganisa kuita kwechigadzirwa chekupedzisira. Atomization yemvura inowanzo shandiswa kugadzira iron poda, nepo gasi atomization inofarirwa kune asiri-ferrous simbi uye alloys.

Metal poda atomization maitiro

Maitiro ekushandura simbi kuita hupfu kuburikidza neatomization inosanganisira akati wandei matanho akakosha:

Kunyungudusa Metal: Danho rekutanga kunyungudutsa simbi kana alloy muchoto. Izvi zvinogona kuitwa uchishandisa nzira dzakasiyana, kusanganisira induction kunyungudika, kunyungudika kwearc kana kuramba kunyungudika. Kusarudzwa kwekunyunguduka kunoenderana nerudzi rwesimbi uye zvinodiwa zvehupfu hwekupedzisira.

Atomization: Mushure mekunge simbi yanyungudutswa, inotamirwa kukamuri yeatomization. Mukamuri iyi, simbi yakanyungudutswa inoiswa kune yakakwira-kudzvanywa gasi kana mvura jets, ichipwanya kuita madonhwe madiki. Ukuru hwemadonhwe hunogona kudzorwa nekugadzirisa kudzvanywa uye kuyerera kweyero yeatomidhi yepakati.

Kutonhodza uye Solidification: Madonhwe anotonhorera uye anosimba nekukurumidza sezvaanopfuura nemukamuri yekupfapfaidza. Mwero wekutonhodza wakakosha sezvo uchikanganisa microstructure uye zvivakwa zvehupfu hunobuda. Kukurumidza kutonhora mazinga anowanzo kuburitsa akatsetseka zvidimbu uye yakawedzera yunifomu microstructure.

Kuunganidza uye Kuronga: Mushure mekusimba, iyo simbi hupfu inounganidzwa uye inorongwa maererano nehukuru hukuru. Izvi zvinowanzoitwa pachishandiswa screening kana air classification techniques. Chigadzirwa chekupedzisira chinogona kuwedzererwa kugadziriswa, senge kukuya kana kusanganisa, kuti uwane inodiwa particle size kugovera uye zvivakwa.

Post-processing: Zvichienderana nekushandiswa, simbi yehupfu inogona kudiwa kumwe kugadziridzwa, senge kupfekedzwa kwepamusoro kana kurapwa kwekupisa, kuwedzera zvivakwa zvavo. Iyi nhanho yakakosha kuti ive nechokwadi chekuti hupfu hunosangana nezvinodiwa zvechikumbiro chakatarisirwa.

Basa reupfu atomization mudziyo

Powder atomization midziyo inzvimbo yakanyatsogadzirirwa kuita iyo simbi poda atomization maitiro nemazvo uye zvinobudirira. Mafekitari aya akashongedzerwa tekinoroji yepamusoro uye michina yekuona kugadzirwa kwehupfu hwemhando yepamusoro. Heano zvimwe zvakakosha zvikamu uye maficha ehupfu atomization mudziyo:

1.Choto

Mwoyo wechero poda atomization midziyo ndiyo choto. Yakagadzirirwa kubata akasiyana simbi uye alloys, mavira aya anopa chaiyo tembiricha yekudzora kuti ive nechokwadi chekunyungudika kwakaringana. Induction furnaces anoshandiswa zvakanyanya nekuda kwekuita kwavo uye kugona kunyungudutsa huwandu hwakawanda hwezvinhu.

2.Atomization System

Atomization masisitimu akakosha kugadzira emhando yepamusoro simbi hupfu. Izvi zvinosanganisira makamuri ekupfapfaidza, nozzles, uye gasi kana mvura yekuunza masisitimu. Iyo yepamusoro atomization system yakagadzirirwa kukwiridzira saizi yekudonha uye kugovera, kuve nechokwadi cheunifomu poda zvivakwa.

3.Kutonhodza uye Kuunganidza System

Mushure meatomization, kutonhora uye kuunganidza masisitimu anoita basa rakakosha mukubata iyo yakaomeswa poda. Aya masisitimu anowanzo sanganisira madutu, mafirita uye hopper kuti aparadzanise hupfu kubva kune atomizing midhiya uye kuitora kuti ienderere mberi kugadzirisa.

4.Kudzora Hunhu uye Kuedzwa

Kudzora kunaka kwakakosha mukugadzirwa kwehupfu.Powder atomization zvinomerakazhinji vane marabhoritari akatsaurirwa kuyedza maitiro emuviri nemakemikari ehupfu hwavanoburitsa. Izvi zvinosanganisira particle size analysis, morphological assessment uye kemikari kuumbwa kwekuongorora kuti ive nechokwadi chekuti hupfu hunosangana nezviyero zveindasitiri.

5.Automation uye Kudzora Systems

Mazuva ano poda atomization zvidyarwa zvakashongedzerwa neyepamberi otomatiki uye kudzora masisitimu anogona kutarisa uye kudzora maitiro ese ekugadzira. Izvi zvinovimbisa kuenderana, zvinoderedza kukanganisa kwevanhu, uye zvinowedzera kushanda kwese.

Kushandiswa kwesimbi upfu

Metal poda inogadzirwa neatomization ine dzakasiyana siyana dzekushandisa mumaindasitiri akasiyana siyana:

Additive Manufacturing: Metal poda yakakosha kune 3D kudhinda tekinoroji, ichibvumira kugadzirwa kweakaomesesa geometries uye lightweight zvimiro.

Aerospace: High-performance metal powders inoshandiswa muzvikamu zveaerospace apo simba-ku-uremu reshiyo uye kuramba kune zvakanyanya mamiriro ezvinhu zvakakosha.

Automotive: Metal poda inoshandiswa kugadzira zvikamu zveinjini, magiya uye zvimwe zvikamu zvakakosha zvinoda kunyatsojeka uye kusimba.

Mishonga Yezvokurapa: Biocompatible simbi poda inoshandiswa kugadzira implants uye prosthetics kuve nechokwadi chekuchengetedza uye kushanda.

Zvishandiso uye Inofa: Metal poda inoshandiswawo mukugadzirwa kwezvishandiso uye inofa, ichipa kuomarara kunodiwa uye kupfeka kuramba.

mukupedzisa

Kushandura simbi kuita hupfu kuburikidza neatomization inzira yakaoma inoita basa rakakosha mukugadzira kwemazuva ano. Powder atomization zvidyarwa zviri pamberi peiyi tekinoroji, zvichipa zvivakwa zvinodikanwa uye hunyanzvi hwekugadzira emhando yepamusoro simbi hupfu kune akasiyana maapplication. Sezvo indasitiri iri kuramba ichishanduka uye ichida zvimwe zvemberi zvinhu, kukosha kwesimbi poda atomization inongokura, ichigadzira nzira yekuvandudza mukugadzira uye zvinhu zvesainzi. Zvingave zviri zvemuchadenga, zvemotokari kana zvekuwedzera kugadzira, remangwana rehupfu hwesimbi rakajeka, rinosundwa nekugona kwehupfu atomization zvidyarwa.
