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 kunoderedzawo 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 ye15 microns, tungsten powder ine particle size ye 0.52 microns uye tungsten powder ye515 microns, wozosanganisa mu25% 30% organic binder. (Zvakadai sewhite wax kana polymethacrylate) jekiseni rekuumba, kuchenesa chiutsi uye neradiation kubvisa binder, uye kunyura mukati kuti uwane yakakwirira-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.Nekuda kwekuti kunyorova kwe molybdenum-mhangura kwakaipisisa kupfuura iyo tungsten-mhangura, kunyanya kana uchigadzira molybdenum-mhangura ine yakaderera copper alloy content, iyo yakanaka density yechinhu mushure mekupinda yakadzikira, zvichikonzera kusimba kwemhepo, magetsi conductivity, uye. thermal conductivity haigone kusangana nezvinodiwa.Kushandiswa kwayo kunorambidzwa.
