Powder metallurgy inzira yekugadzira hupfu hwesimbi kana kushandisa hupfu hwesimbi (kana musanganiswa wehupfu hwesimbi uye husiri hwesimbi hupfu) sehupfu, kugadzira nekunyungudusa, nekugadzira zvinhu zvesimbi, zvinoumbwa nemhando dzakasiyana dzezvigadzirwa.Powder metallurgy nzira uye kugadzirwa kweceramics vane nzvimbo dzakafanana, ese ari maviri eupfu sintering tekinoroji, saka, nhevedzano yeupfu simbi tekinoroji inogona kushandiswawo kugadzira zvedongo.Nekuda kwemabhenefiti epoda metallurgy tekinoroji, yave kiyi yekugadzirisa dambudziko rezvinhu zvitsva, uye inoita basa rakakosha mukugadzirwa kwezvinhu zvitsva.

Saka rudzii rwekuchinja kwakaitika kubva pachinyakare poda metallurgy kuenda kumazuva ano simbi simbi?

1. Misiyano yehunyanzvi

Iyo yechinyakare poda metallurgy tekinoroji inonyanya kuburikidza nekuumbwa kwehupfu uye zvakajairwa sintering.Modern poda metallurgy tekinoroji Nzira yekugadzira nekunyungura zvinhu zvesimbi kana zvidimbu zvemagetsi zvakagadzirwa nehupfu hwesimbi, hunogona kugadzirwa zvakananga pasina kugadzirwa.Zvigadzirwa zvinogona kugadzirwa nelaser sintering, microwave sintering uye inopisa isostatic kudzvanya kwehupfu.

2. Zvinhu zvakasiyana-siyana zvekugadzirira

Traditional poda metallurgy inogona chete kugadzira zvakajairika alloy zvinhu, senge simbi isina tsvina uye aruminiyamu alloy, ine yakaderera zvivakwa.Mazuva ano poda metallurgy inogona kugadzira akasiyana emhando yepamusoro-inoshanda zvimiro zvemukati uye zvimwe zvakakosha zvinhu.Semuenzaniso, poda superalloys, simbi isina tsvina, simbi base alloys, yakakwirira tembiricha superconducting zvinhu, ceramic matrix composites, nanomaterials, iron base, cobalt chromium alloy zvinhu.

3. Tekinoroji yekugadzirira yepamusoro

Zvimedu zvehupfu zvakagadzirirwa nehunyanzvi hwekugadzira hupfu hwakakasharara uye saizi yehupfu haina kufanana.Tekinoroji yemazuva ano yepoda simbi yekugadzira inosanganisira tekinoroji yejet deposition, tekinoroji yemagetsi laser yekunyungudutsa, nezvimwewo, uye hupfu hwakagadzirirwa hudiki uye hwakanyanya.

4. Zvigadzirwa zvekuumba

Traditional poda metallurgy tekinoroji inodhinda zvigadzirwa zvine hutsinye, uye nehungwaru kudhinda kwezvikamu zvakakura zvine maitiro akareruka.Zvikamu zvakagadzirirwa neazvino poda metallurgy tekinoroji zvakanyanya uye zvakanyanya kuoma, kwete chete chimiro chinoshanduka, asiwo saizi uye hunhu hunodiwa hwakanyanya.Kuwanda kwechikamu chekushandisa.
