Nzira yekugadzira yetungsten mhangura alloy:
Iyo tekinoroji maitiro ekugadzira tungsten-mhangura alloy nehupfu metallurgy nzira inoshandiswa kusanganisa, kudzikisira, kuumba, kunyungudika, kunyunguduka, kupinza uye kutonhora kugadzirwa kwehupfu.Tungsten-mhangura kana molybdenum-mhangura yakasanganiswa poda inoputirwa muchikamu chemvura pa1300-1500 ° mushure mekuvharirwa kuumbwa.Zvinhu zvakagadzirirwa neiyi nzira zvine hurombo hwakafanana, kune nzvimbo dzakawanda dzakavharwa, uye density yakanaka kazhinji yakaderera pane 98%.Inogona kuvandudza sintering chiitiko uye kuvandudza kunaka kwe tungsten-mhangura uye molybdenum-mhangura alloys.Zvisinei, nickel activation uye sintering ichaderedza zvakanyanya kushandiswa kwemagetsi uye kupisa kwezvinhu, uye kuiswa kwetsvina mumagetsi alloying kuchaderedzawo maitiro ekugadzirisa zvinhu;iyo oxide co-kudzoreredza nzira yekugadzira hupfu ine inorema tekinoroji maitiro uye yakaderera kugadzirisa simba, zvichiita kuti zviome kuita batch process.
1. Injection molding nzira Yakakwirira-density tungsten alloy inogadzirwa nejekiseni molding nzira.Nzira yekugadzirwa kwayo ndeyekusanganisa nickel powder, copper tungsten powder kana iron poda ine yunifomu particle size ye 15 microns, tungsten powder ine particle size ye 0.52 microns uye tungsten powder ye515 microns, wobva wasanganisa mu25% 30% organic binder (Senge wakisi chena kana polymethacrylate kuti ibvise mushizha, kuchenesa uye kuchenesa mukati, kuchenesa uye kuchenesa mundiro, kuchenesa uye kuchenesa mundiro, bvisa bhinda remu. density tungsten alloy.
2. Copper oxide powder nzira yeCopper oxide powder (kusanganisa uye kugaya kudzorera mhangura) panzvimbo yesimbi yemhangura yehupfu, alloy yemhangura inoumba matrix anoenderera mberi mu sintered compact, uye tungsten inoshandiswa sechinhu chinosimbisa.Iyo yakakwira yekuzvimba chikamu inoganhurwa neyakatenderedza chikamu chechipiri, uye hupfu hunopiswa muhunyoro hwekushisa hwakaderera.Kusarudzwa kwehupfu hwakatsetseka hunogona kuvandudza sintering kuita uye densification, zvichiita kuti ipfuure 99%.
3. Iyo tungsten uye molybdenum skeleton nzira yekupinza inotanga inomisikidza tungsten hupfu kana molybdenum poda kuti iumbe, uye inoiisa mu tungsten uye molybdenum skeleton ine imwe porosity, uye yobva yapinza mhangura.Iyi nzira inokodzera tungsten mhangura uye molybdenum mhangura zvigadzirwa zvine yakaderera mhangura.Kuenzaniswa ne tungsten mhangura, molybdenum mhangura ine zvakanakira zvemhando diki, kugadzirwa kuri nyore, mutsara wekuwedzera coefficient, thermal conductivity uye mamwe makuru emuchina zvivakwa uye tungsten mhangura.Kunyangwe basa rekudzivirira kupisa harina kunaka senge tungsten mhangura, iri nani pane zvimwe zvinhu zvinodzivirira kupisa, saka ine tarisiro iri nani yekushandisa.Nemhaka yekuti kunyorova kwe molybdenum-mhangura kwakaipisisa kupfuura iyo tungsten-mhangura, kunyanya kana uchigadzira molybdenum-mhangura ine yakaderera yemhangura alloy content, iyo yakanaka density yezvinyorwa mushure mekupinda kwakaderera, zvichikonzera kusimba kwemhepo, magetsi conductivity, uye thermal conductivity haigone kusangana nezvinodiwa.Kushandiswa kwayo kunorambidzwa.
