Nqus sintering rauv yog tsuas yog siv rau sintering active hlau thiab insoluble hlau, raws li zoo raws li nyuaj alloys, sib nqus cov ntaub ntawv, thiab stainless hlau. Lub tshuab nqus tsev sintering rauv yog qhov ua tau qis-siab (nqus) sintering. Qhov siab dua lub tshuab nqus tsev kawm ntawv, qhov ze dua rau qhov nruab nrab qhov nruab nrab, thiab qhov ntau nws tsis muaj tshuaj tiv thaiv nrog cov khoom siv.
(1) Lub tshuab nqus tsev yog qhov zoo rau kev tshem tawm cov roj adsorbed thiab muaj txiaj ntsig zoo rau kev txhawb nqa shrinkage tom qab theem ntawm sintering.
(2) Lub tshuab nqus tsev yog qhov tsim nyog rau kev tshem tawm cov impurities lossis lawv cov oxides xws li silicon, aluminium, magnesium, calcium, thiab lwm yam, ua lub luag haujlwm hauv kev ua kom huv.
(3) Lub tshuab nqus tsev tuaj yeem txhim kho lub wettability ntawm cov kua-theem sintering, uas yog qhov tsim nyog rau shrinkage thaum lub sij hawm sintering txheej txheem thiab txhim kho microstructure ntawm cov hlau.
(4) Lub tshuab nqus tsev yog qhov zoo tagnrho inert cua. Thaum lwm yam kev txo qis lossis inert gases tsis haum, lossis rau cov ntaub ntawv uas ua rau decarburization thiab carburization, lub tshuab nqus tsev sintering tuaj yeem siv tau.
(5) Txo cov kev sib kis ntawm cov khoom tsis zoo (dej, oxygen, nitrogen, thiab lwm yam) hauv cov huab cua ntawm cov khoom. Piv txwv li, nws yog ib qho nyuaj rau txo cov dej cov ntsiab lus hauv electrolytic hydrogen rau * * * -40 degree ; Thaum lub tshuab nqus tsev sintering, lub tshuab nqus tsev tsuas yog ob peb puas Pa yog sib npaug rau cov dej noo ntawm * * * -40 degree .
