Chii chinonzi atomization yevacuum metal powder?

Mundima yemazuva ano zvinhu zvesainzi uye engineering, tekinoroji yekugadzirira yehupfu dzesimbi inogara ichigadzira uye kuvandudza. Pakati pavo, vacuum simbi poda atomization tekinoroji, senzira yakakosha yekugadzirira, ine yakasarudzika mabhenefiti uye yakafara tarisiro yekushandisa. Ichi chinyorwa chinozonyura mune iyo pfungwa yevacuum simbi poda atomization, kusanganisira misimboti, nzira, maitiro, mashandisirwo, uye ramangwana rekusimudzira mafambiro.

1, Mhedziso yeMetal Powder Atomization Technology

Metal poda atomization inzira yekushandura simbi yakanyungudutswa kuita zvidimbu zvidimbu zvehupfu. Nekushandisa chaiwo maatomu emidziyo, simbi yemvura inoparadzirwa kuita madonhwe madiki, ayo anokurumidza kusimba panguva yekutonhora kugadzira simbi hupfu. Metal poda atomization tekinoroji inogona kugadzirira akasiyana simbi hupfu ane akasiyana particle saizi, maumbirwo, uye nziyo kusangana nezvinodiwa zveminda dzakasiyana.

2, Nheyo yevacuum simbi poda atomization

Vacuum simbi poda atomization inzira yesimbi poda atomization inoitwa munzvimbo yevacuum. Nheyo huru ndeye kushandisa mhepo inomhanya-mhanya, mvura inodzvanywa, kana simba repakati kuparadzira simbi yakanyungudutswa kuita madonhwe madiki pasi pemamiriro evacuum. Nekuda kwekuvapo kwenzvimbo yevacuum, kusangana pakati pemadonhwe esimbi nemhepo kunogona kuderedzwa zvinobudirira, kudzivirira oxidation uye kusvibiswa, nekudaro kuvandudza kunaka kwesimbi upfu.

Mukuita kwevacuum simbi poda atomization, iyo simbi mbishi zvinhu zvinotanga kupiswa kune yakanyungudutswa. Zvadaro, kuburikidza nemuromo weatomizing chaiyo, simbi yakanyungudutswa inopfapfaidzwa nekumhanya kukuru uye inopindirana neatomizing medium (yakadai seinert gas, high-pressure water, etc.) kuti igadzire madonhwe maduku. Aya madonhwe anokurumidza kutonhora uye kusimba munzvimbo ine vacuum, pakupedzisira achigadzira simbi hupfu.

3, Nzira yevacuum simbi poda atomization

(1) Vacuum Inert Gasi Atomization Method

Musimboti: Simbi yakanyungudutswa inopfapfaidzwa kunze kuburikidza nemuromo munzvimbo yevacuum, uye gasi inert (senge argon, nitrogen, nezvimwewo) inoshandiswa kukanganisa kuyerera kwesimbi, ichiiparadzira kuita madonhwe madiki. Inert magasi anoita basa mukutonhodza nekudzivirira madonhwe esimbi panguva yeatomization, kudzivirira oxidation uye kusvibiswa.

Hunhu: Kuchena kwepamusoro uye yakanaka sphericity simbi poda inogona kugadzirwa, yakakodzera minda inoda hupfu hwemhando yepamusoro, senge aerospace, zvemagetsi, nezvimwe.

(2) Vacuum atomization nzira

Musimboti: Simbi yakanyungudutswa inopfapfaidzwa kunze kuburikidza nemhuno munzvimbo yevacuum, uye inomhanya-mhanya kuyerera kwemvura inokanganisa kuyerera kwesimbi yesimbi, ichiiparadzira mumadonhwe madiki. Mvura inobata basa mukutonhodza nekupwanya simbi yemvura inoyerera panguva yeatomization process.

Hunhu: Inogona kugadzira simbi hupfu neyakatsetseka particle size uye yakaderera mutengo, asi dhigirii yeoxidation yehupfu yakakwira uye inoda kunotevera kugadziriswa.

(3) Vacuum centrifugal atomization nzira

Musimboti: Isai simbi yakanyungudutswa mudhisiki rinotenderera recentrifugal kana crucible, uye pasi pekuita kwesimba recentrifugal, simbi yakanyungudutswa inokandwa kunze uye inoparadzirwa mumadonhwe madiki. Madonhwe anotonhodza uye akasimba munzvimbo ine vacuum, achigadzira simbi hupfu.

Zvimiro: Inogona kugadzira simbi hupfu nehupamhi sphericity uye yunifomu particle saizi kugovera, yakakodzera kugadzirira yakakwirira-inoshanda simbi poda zvinhu.

4, Hunhu hweVacuum Metal Powder Atomization

①Kuchena kwepamusoro

Nzvimbo yevacuum inogona kunyatso kudzikisa kusangana pakati pesimbi poda nemhepo, kudzivirira oxidation uye kusvibiswa, uye nekudaro kunatsiridza kuchena kwehupfu.

Kune zvimwe zvinhu zvesimbi zvine kuchena kwakanyanya zvinodiwa, senge titanium alloys, yakakwirira-tembiricha alloys, nezvimwewo, vacuum simbi poda atomization tekinoroji inzira yakanaka yekugadzirira.

Inoshandiswa pakugadzira zvinhu zvepamusoro zvemotokari zvakadai semasilinda einjini, pistons, nezvimwewo. Zvigadzirwa zvepowder metallurgy zvine zvakanakira zvekureruka, kusimba kwepamusoro, uye kupfeka kwakanaka kuramba, izvo zvinogona kuvandudza mashandiro uye hupfumi hwemafuta emotokari.

Iyo simbi poda inogadzirwa nevacuum simbi poda atomization inogona kusangana nezvinodiwa zveindasitiri yemotokari zvezvinhu zvenyama.

6、 Iyo Yekuvandudza Trend yeVacuum Metal Powder Atomization Technology

① Hukuru uye otomatiki emidziyo

Nekuenderera mberi kwekukura kwemusika kudiwa, vacuum simbi poda atomization michina inosimudzira yakanangana nehukuru-hukuru uye otomatiki gwara, inovandudza kugadzirwa kwemhando uye mhando yechigadzirwa.

Iyo otomatiki yekudzora sisitimu inogona kuwana chaiyo kutonga kweiyo atomization maitiro, kuvandudza kugadzikana uye kuvimbika kwekugadzirwa.

②Kuvandudzwa kweatomization midhiya mitsva

Tsvagurudza uye gadzira mhando nyowani dzeatomization midhiya, senge supercritical fluid, plasmas, nezvimwe, kuvandudza kunaka uye kuita kwesimbi hupfu.

Iyo nyowani yeatomization yepakati inogona kuwana yakanyatsoshanda atomization maitiro uye kuderedza mutengo wekugadzira.

③Kuvandudza tekinoroji yehupfu mushure mekurapwa

Iyo simbi poda inogadzirwa nevacuum simbi poda atomization inowanzoda post-kurapwa, senge kuongorora, kusanganisa, kurapwa kwepamusoro, nezvimwe, kusangana nezvinodiwa zveminda yakasiyana yekushandisa.

Gadzira tekinoroji yehupfu mushure mekurapa tekinoroji yekuvandudza mashandiro uye kukosha kwehupfu.

④Kugadzirira kweupfu huzhinji hunoshanda

Nekubatanidza nzira dzakasiyana dzekugadzirira uye matekiniki, akaumbwa simbi poda ane akawanda mabasa anogona kugadzirwa, senge nanocomposite poda, inoshanda graded poda, nezvimwe.

Multi functional composite powders inogona kusangana nezvinodiwa zvezvinhu zvivakwa pasi pemamiriro ekushanda akaoma uye kuwedzera minda yekushandisa yesimbi poda.

8, Mhedziso

Vacuum simbi poda atomization tekinoroji inzira yepamberi yekugadzira simbi hupfu, inoratidzwa nekuchena kwepamusoro, yakanaka sphericity, yunifomu saizi yekugovera, uye yunifomu yemakemikari kuumbwa. Iyi tekinoroji ine tarisiro yakafara yekushandiswa muminda yakadai seaerospace, zvemagetsi, zvishandiso zvekurapa, uye mota. Nekuenderera mberi kwekusimudzira uye hunyanzvi hwetekinoroji, vacuum simbi poda atomization tekinoroji icharamba ichivandudza uye kuwedzera, ichiita mipiro yakakura mukusimudzira zvinhu zvesainzi uye engineering.
