Ceramic sintering maitiro

Sintering ndiyo tekinoroji inoshandisa kupisa simba kuti densify hupfu mabhiri. Tsanangudzo ye sintering inoreva densification process ye porous ceramic billet pasi pemamiriro ekushisa epamusoro, nzvimbo yepasi yakaderedzwa, iyo porosity inodzikiswa, uye michina yemagetsi inovandudzwa. Chete nekuziva mutemo wekuchinja kwemuviri mukuita kupisa kwekushisa kwakanyanya, kusarudza nemazvo uye kugadzira hovhoni, kugadzira nesainzi uye kuita hurongwa hwekupfura, uye kunyatsoita maitiro ekushandisa ekurodha nekupfura, mhando yechigadzirwa inogona kuvandudzwa, kushandiswa kwemafuta kuderedzwa, uye mabhenefiti akanaka ehupfumi anowanikwa.

Sintering parameter

Iyo tekinoroji paramita inokanganisa sintering yezvinhu zveceramic

(1) Mhedzisiro yekupisa tembiricha pakuita kwechigadzirwa

1. Iyo tembiricha yekupisa inoreva tembiricha inoenderana kana muviri weceramic wadzingwa kuti uwane iyo yakakwana pfuma, kureva, kupisa kwekumisa moto panguva yekushanda.
2. Chiyero chekupisa kupisa chinokanganisa zvakananga saizi uye nhamba yezviyo. Kune yakasimba chikamu diffusion kana mvura chikamu recrystallization, zvinobatsira kuwedzera tembiricha yekupfura. Nekudaro, kune yakakosha porcelain, yakanyanya kupisa tembiricha yekupisa inoita kuti saizi yezviyo ive yakakura kana kuti nhamba shoma yezviyo iwedzere zvakanyanya, ichiparadza kufanana kwechimiro chesangano, nekudaro kukanganisa kwemagetsi echigadzirwa.

(2) Mhedzisiro yekubata nguva pakuita kwechigadzirwa

Kuchengeta tembiricha yepamusoro yekupfuta kweimwe nguva yenguva kuchaita, kune rumwe rutivi, kuita kuti shanduko yemuviri nemakemikari ive yakakwana, kuitira kuti muviri wakasvibira uve nechikamu chemvura chakakwana uye saizi yezviyo yakakodzera, uye kune rumwe rutivi, chimiro chesangano chichawedzerawo yunifomu. Zvisinei, kana nguva yekuchengetedza kupisa kwakanyanyisa, zviyo zvekriststal zvichanyunguduka, izvo zvisingakodzeri kuumbwa kweskeleton yakasimba mumhepo isina chinhu uye inoderedza maitiro emagetsi.

(3) Mhedzisiro yemhepo yekupfura pakuita kwechigadzirwa

1. Kufurira kwemhepo pamusoro pekuwedzera-kupfuta kwekuwedzera kwemiviri yeceramic
2. Mhedzisiro yemhepo pane shrinkage uye sintering yegirinhi muviri
3. Kufurira kwemamiriro ekunze pane ruvara uye transmittance yechinhu chisina chinhu uye kunaka kweiyo glaze layer.

(4) Pesvedzero yekudziya uye kutonhora kumhanya pakuita kwechigadzirwa

Solid-phase sintering kazhinji inogona kukamurwa kuita nhanho nhatu: nhanho yekutanga, iyo inonyanya kuratidzwa nekuchinja kwechikamu chechimiro; danho repakati, iro rinonyanya kuratidzwa nekuchinja kwepore shape; danho rekupedzisira, iro rinonyanya kuratidzwa nekuderedzwa kwehukuru hwepore.

Liquid phase sintering (LPS for short) zvinoreva kunyura kwemuviri une hupfu hwakawanda. Iyo tembiricha yekunyunguduka inodarika tembiricha yekunyungudika yeimwe yehupfu, kuitira kuti mvura yechikamu sintering iitike panguva yekunyungudika. process.

mukana:

1. Kuvandudza sintering kutyaira simba.
2. Ceramic composite zvinhu zvine inodzorwa microstructure uye yakagadziridzwa zvivakwa zvinogona kugadzirirwa

Featured sintering-hot press sintering

Kudzvanya kunopisa kunoshandisa kudzvanya kune isina chinhu panguva imwe chete panguva yekuita sintering, iyo inomhanyisa maitiro e densification. Naizvozvo, tembiricha yekupisa yekupisa sintering yakaderera uye nguva yekupisa ipfupi.

Tekinoroji yekutsikisa tekinoroji ine nhoroondo yemakore makumi manomwe uye yakatanga kushandiswa mukugadzirira tungsten carbide uye tungsten poda dense zvikamu. Iko zvino inoshandiswa zvakanyanya mumitambokugadzirwa kweceramics,upfu metallurgyuye composite zvinhu.

Zvakanakira hot press sintering

1. Iyo inodiwa yekuumba kumanikidza inongova 1/10 yeiyo yekutonhora yekutsikirira nzira
2. Kuderedza kupisa kwekupisa uye kupfupisa nguva yekupisa kunodzivisa kukura kwezviyo.
3. Zviri nyore kuwana zvigadzirwa zvine yakanaka mechanical properties uye magetsi emagetsi.
4. Kugona kugadzira zvigadzirwa zvine maumbirwo akaomarara uye nemadimendi chaiwo.
