Vacuum Sintering yeTungsten Carbide Zvigadzirwa

Vacuum sintering zvinoreva kuti hupfu, hupfu compact, kana mamwe marudzi ezvigadzirwa zvinodziiswa patembiricha yakakodzera munzvimbo yevacuum kuti iwane kubatana pakati pezvimedu kuburikidza nekutama kweatomu. Sintering kugadzira porous poda compacts ane alloys ane zvimwe zvimiro uye zvivakwa.

Cemented carbide vacuum sintering inzira yekuisa pasi pe101325Pa. Sintering pasi pevacuum mamiriro ekudzikisira zvakanyanya kuvhiringidza gasi adsorbed pahupfu uye gasi mumapores akavharika pane densification. Sintering inobatsira kune diffusion process uye densification uye inogona kudzivirira kuita pakati pesimbi uye zvimwe zvinhu zviri mumhepo panguva yekupisa. Kunyanya kunatsiridza kunyorova-kugona kweiyo mvura binder chikamu uye yakaoma simbi chikamu, asi vacuum sintering inofanira kungwarira kudzivirira evaporation kurasikirwa kwecobalt.

Cemented carbide vacuum sintering inogona kukamurwa kuita nhanho ina. Kune nhanho yekubvisa plasticizer, pre-sintering nhanho, yakakwirira-tembiricha sintering nhanho, uye nhanho yekutonhora.

Zvakanakira vacuum sintering yecemented carbide ndeiyi:

1. Deredza kusvibiswa kwezvinhu zvinokonzerwa nemagasi anokuvadza munharaunda. Semuenzaniso, zvakanyanya kuoma kusvika padova reminus 40 ℃ yemvura yehydrogen inogadzirwa ne electrolysis, asi hazvina kunetsa kuwana dhigirii rakadaro rekutsvaira;

2. Vacuum ndiyo yakanyanya kunaka inert gasi. Kana mamwe magasi ekudzorera uye anert asina kukodzera, kana kune zvinhu zvinowanzoita decarburization uye carburization, vacuum sintering inogona kushandiswa;

3. Vacuum inogona kuvandudza kunyorova-kukwanisa kwechikamu chemvura sintering, iyo inobatsira kuderedza uye kuvandudza chimiro chesimende carbide;

4. Vacuum inobatsira kubvisa tsvina kana oxides yakadai seSi, Al, Mg, uye inochenesa zvinhu;

5. Vacuum inobatsira kuderedza adsorbed gasi (inosara gasi mumapores uye reaction gasi zvigadzirwa) uye ine mhedzisiro yakajeka pakusimudzira shrinkage muchikamu chekupedzisira che sintering.

Kubva pakuona kwehupfumi, kunyange zvazvo iyo vacuum sintering midziyo ine mari yakawanda uye yakaderera yakabuda pachoto, simba rekushandisa rakaderera, saka mari yekuchengetedza vacuum yakaderera zvikuru kudarika mutengo wemamiriro ekugadzirira. Muchikamu chemvura chekunyungudika pasi pevacuum, kuparara kwekuparara kwebinder simbi zvakare inyaya yakakosha, iyo isingashanduki chete uye inokanganisa kuumbwa kwekupedzisira uye chimiro che alloy asiwo inotadzisa sintering pachayo.

Cemented carbide kugadzira idanho rakaomarara. ZZBETTER inotora zvese zvekugadzira zvakakomba, inonyatso kudzora kunaka kwesimende zvigadzirwa zve carbide, uye inopa mhinduro kumamiriro ekushanda akaomarara.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
