Infiltration Maitiro ehupfu metallurgy

Iyo poda compact inobatwa nesimbi yemvura kana kunyudzwa mumvura simbi, ma pores ari mukompakiti anozadzwa nesimbi yemvura, uye iyo compact zvinhu kana zvikamu zvinowanikwa nekutonhodza pasi.Kuita uku kunonzi kunyudza.Iyo yekunyudza inotsamira pane yekunze simbi yakanyungudutswa kuti inyorove iyo poda porous muviri.Pasi pekuita kwecapillary force, iyo simbi yemvura inoyerera ichitevedza pores pakati pezvimedu kana pores mukati mezvimedu kusvika mapores azara zvachose.

Zvakanakira kupinza kwemhangura yehupfu metallurgy iron-based materials:
1. Kuvandudza zvinhu zvemuchina;

2. Kuvandudza electroplating performance;

3. Kuvandudza brazing performance;

4. Kuvandudza machining performance;

5. Kuvandudza magetsi uye kupisa conductivity;

6. Zviri nyore kudzora ukuru hwezvikamu;

7. Iva nemaitiro akanaka ekuisa chisimbiso;

8. Zvikamu zvakawanda zvinogona kusanganiswa;

9. Kuvandudza kunaka kwekudzima;

10. Kupindira kwepanzvimbo yezvikamu zvakakosha zvinoda kusimba uye kuomesa zvinhu.

Zvikonzero:

1. Skeleton density
Sezvo skeleton density inowedzera, simba remhangura-inopinza sintered simbi inowedzera zvakanyanya, uye kuoma kunowedzerawo.Izvi zvinokonzerwa nekuwedzera kweskeleton density, kuwedzera kwehuwandu hwepearlite, uye zvishoma zvishoma zvemhangura.Panyaya yemutengo, kusarudza yakakwira skeleton density inogona kuderedza mhangura yemukati, nekudaro ichivandudza mabhenefiti ehupfumi.

2. Wedzera chinhu Sn
Kuwedzerwa kweiyo yakaderera melting point element Sn inobatsira kuwedzera density uye simba remhangura-yakapinda sintered simbi.Kubva kuCu-Sn alloy chikamu dhizaini, zvinogona kuoneka kuti mhangura alloys ine Sn ine yakaderera yemvura chikamu chekugadzira tembiricha, iyo inogona kukurudzira kupfava kupinza kwemhangura alloys.

3. Tembiricha
Sezvo kutonhora kunowedzera, chiyero chekuwedzera kwezviyo chinowedzerawo, izvo zvinokanganisa kuvandudza simba.Nokudaro, sintering-infiltration yakakodzera uye nguva yekubata inofanira kusarudzwa pasi pechikonzero chekuvimbisa kusanganiswa kwakakwana uye homogenization yeFe-C, kupindira kwakazara kweCu, uye kusimba kwakasimba kwekugadzirisa kweFe-Cu.
