Upfu metallurgyinogadzirwa nekugadzira hupfu, kudzvanya molding,sintering, uye post-processing, uye sintering ndeimwe yeakakosha maitiro ehupfu metallurgy. Munguva yesimbi poda sintering process, poda zvidimbu zvinofanirwa kuyerera, kupararira, kunyunguduka, kusanganisa uye mamwe maitiro emuviri nemakemikari. Iyo nzira inowedzera densifies hupfu uye inobvisa mamwe kana ese ma pores ayo. Kune zvakare akati wandei sintering nzira dzeupfu metallurgy sintering. Saka, ndezvipi zvinowanzoshandiswasintering nzirazveupfu metallurgy?
Powder metallurgy sintering nzira dzinowanzowira muzvikamu zvinotevera:
1. Liquid phase sintering
Kana pane zvikamu zviviri kana kupfuura muhupfu compact, sintering inogona kuitwa pamusoro pekunyunguduka kwechimwe chikamu, saka chikamu chiduku chemvura chinowanikwa muupfu compact panguva yekupisa.
2. Pressure sintering
Munguva yesimbi poda sintering, kudzvanywa kunoiswa kumuviri wehupfu kusimudzira maitiro ayo e densification. Pressure sintering dzimwe nguva inofanana nekutsikirira kunopisa, inova nzira inosanganisa kuumbwa nekunyunguduka kwehupfu kuti uwane zvakananga zvikamu zvinopisa.
3. Activation sintering
Mamwe matanho emuviri kana emakemikari anogamuchirwa mukuita sintering, kuitira kuti tembiricha yekupisa ideredze zvakanyanya, nguva yekupisa inopfupikiswa zvakanyanya, uye kushanda kwemuviri we sinter kunovandudzwa uye kuvandudzwa.
4. EDM sintering
Kana muviri wehupfu wakaumbwa uye wakatsikirirwa, yakananga ikozvino uye pulse magetsi inoshandiswa kugadzira arc pakati pehupfu hwehupfu hwekuita sintering; panguva ye mim sintering process, kudzvanywa kunoshandiswa zvishoma nezvishoma kune workpiece, uye maitiro maviri ekugadzira uye sintering anosanganiswa.
5. Poda yakasimba chikamu sintering
Iyo poda sintering nzira umo yakasununguka poda kana compacts hainyungudika panguva yekupisa. Powder solid-phase sintering inogona kukamurwa kuita mhando mbiri: unit-system solid-phase sintering uye yakawanda-system solid-phase sintering zvichienderana nehuwandu hwezvikamu.
Iri pamusoro apa ndiyo sumo kune zvakajairika sintering nzira upfu metallurgy.Sintering muupfu metallurgy iri mukuru-tembiricha kurapwa muitiro kuti mberi anosanganisa compacts kana vakasununguka upfu miviri kuvandudza simba uye zvimwe zvinhu.
Kubva payakagadzwa, Minxin Powder Metallurgy yakazvipira kutsvagisa nekusimudzira, kugadzira uye kutengesa kwesimbi poda yekutsikirira nesimbi.upfu jekiseni kuumba. Kwemakore gumi, timu yeR&D yakatarisana nekugadzira yakakwira-chaiyo poda simbi: chaiyo zvikamu mafuta-akaiswa mabhengi, zvikamu zvechimiro, magiya, simbi isina tsvina poda metallurgy zvikamu uye zvakasiyana-siyana jekiseni jekiseni zvigadzirwa. Material: mhangura dzakatevedzana, mhangura simbi dzakatevedzana, simbi dzakatevedzana, alloy simbi, Stainless simbi ceramics, etc..
