Vacuum Sintering na Tungsten Carbide Products

Vacuum sintering yana nufin cewa foda, foda compacts, ko wasu nau'ikan kayan ana dumama a madaidaicin zafin jiki a cikin yanayi mara kyau don cimma alaƙa tsakanin barbashi ta hanyar ƙaura ta atomatik. Sintering shine don yin ƙaƙƙarfan ƙaƙƙarfan foda wanda ke da gami tare da wasu sifofi da kaddarorin.

Cimemented carbide vacuum sintering tsari ne na sintiri a ƙarƙashin 101325Pa. Sintering a ƙarƙashin yanayi mara kyau yana rage tasirin hana iskar gas a saman foda da iskar gas a cikin rufaffiyar pores akan ƙima. Sintering yana da amfani ga tsarin watsawa da haɓakawa kuma yana iya guje wa halayen da ke tsakanin karfe da wasu abubuwa a cikin yanayi yayin aikin sintiri. Mahimmanci inganta rigar-ikon lokaci mai ɗaure ruwa da kuma lokacin ƙarfe mai wuya, amma vacuum sintering ya kamata a kula don hana asarar cobalt.

Ciminti carbide injin sintering gabaɗaya za a iya raba hudu matakai. Akwai matakin cire filastik, mataki na farko, matakin zafin jiki mai zafi, da matakin sanyaya.

Abubuwan da ke tattare da vacuum sintering na simintin carbide sune:

1. Rage gurbatar kayayyaki da iskar gas mai cutarwa ke haifarwa. Misali, yana da matukar wahala a isa wurin raɓa na 40 ℃ don abun cikin ruwa na hydrogen da ake samarwa ta hanyar lantarki, amma ba shi da wahala a sami irin wannan matakin na injin;

2. Vacuum shine mafi kyawun iskar inert. Lokacin da sauran iskar gas mai sake dawowa da inert ba su dace ba, ko kuma don kayan da ke da alaƙa da lalatawa da carburization, ana iya amfani da vacuum sintering;

3. Vacuum iya inganta rigar-ikon na ruwa lokaci sintering, wanda yake da amfani ga shrinkage da inganta tsarin siminti carbide;

4. Vacuum yana taimakawa wajen cire datti ko oxides kamar Si, Al, Mg, da kayan tsarkakewa;

5. Vacuum yana da amfani don rage iskar gas (sauran iskar gas a cikin pores da samfuran iskar gas) kuma yana da tasiri mai tasiri akan inganta haɓakawa a cikin mataki na gaba na sintering.

Daga ra'ayi na tattalin arziki, ko da yake na'ura mai ba da wutar lantarki yana da babban zuba jari da ƙananan kayan aiki a kowace tanderun, yawan wutar lantarki yana da ƙasa, don haka farashin kula da vacuum yana da ƙasa fiye da farashin yanayin shirye-shiryen. A cikin lokaci na ruwa na sintering a karkashin injin, da asarar volatilization na dauri karfe ne kuma wani muhimmin batu, wanda ba kawai canje-canje da kuma rinjayar karshe abun da ke ciki da kuma tsarin na gami amma kuma hana sintering tsari kanta.

Samar da carbide da aka yi da siminti tsari ne mai tsauri. ZZBETTER yana ɗaukar kowane daki-daki na samarwa da mahimmanci, yana sarrafa ingancin samfuran siminti na siminti, kuma yana ba da mafita ga yanayin aiki mai wahala.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
