Sintering Maitiro eTungsten Carbide

Iyo sintering process ndeimwe yematanho anodiwa mukugadzira tungsten carbide zvigadzirwa. Zvinoenderana nehurongwa hwekuita sintering, iyo sintering process inogona kukamurwa kuita zvikamu zvina zvakakosha. Ngatitaure nezve aya matanho mana zvakadzama uye iwe uchaziva zvakawanda nezve sintering maitiro e tungsten carbide.

1. Kubviswa kweKugadzira Agent uye Burn-In stage

Nekuda kwekukwira kwetembiricha, hunyoro, gasi, uye doro rasara mupfapfaidzo yakaoma zvinotorwa neupfu kana kuti molding agent kusvika yanyungudika.

Kuwedzera kwetembiricha kunozotungamira kune zvishoma nezvishoma kugadzira maajenti 'kuora kana vaporization. Ipapo iyo yekugadzira mumiriri inozowedzera iyo kabhoni yemukati yemuviri wakasvibiswa. Huwandu hwekabhoni yemukati hunosiyana nemusiyano wemugadziri weiyo akasiyana sintering process.

Pakupisa kwekupisa, kuderedzwa kwehydrogen ye cobalt uye tungsten oxide hakuiti zvakasimba kana vacuum ichiderera uye ichinyura.

Nekuwedzera kwekushisa uye annealing, iyo poda yekubata kushushikana inobviswa zvishoma nezvishoma.

Iyo yakasungwa simbi poda inotanga kupora uye kudzokorora. Sezvo kupararira kwepamusoro kunoitika, simba rekumanikidza rinowedzera. Iyo block size shrinkage haina kusimba uye inogona kugadziriswa seplasticizer isina chinhu.

2. Solid State Sintering Stage

Iyo sintered muviri inobvumirana zviri pachena mune yakasimba state sintering nhanho. Mune ino nhanho, kuita kwakasimba, kupararira, uye kuyerera kwepurasitiki kunowedzera, uye muviri wakanyungudutswa unobvumirana.

3. Liquid Sintering Stage

Kana iyo sintered body yaoneka yemvura chikamu, iyo shrinkage inopedzwa nekukurumidza. Ipapo iyo yakakosha chimiro cheiyo alloy ichaumba pasi peiyo crystalline shanduko. Kana tembiricha yasvika kune eutectic tembiricha, iyo solubility yeWC muCo inogona kusvika 10%. Nekuda kwekukakavadzana kwepamusoro kwechikamu chemvura, zvimedu zvehupfu zvakavharwa kune mumwe nemumwe. Nokudaro, chikamu chemvura zvishoma nezvishoma chakazadza pores muzvikamu. Uye kuwanda kweiyo block kunowedzera zvakanyanya.

4. Kutonhora Danho

Padanho rekupedzisira, tembiricha inodonha kusvika kune tembiricha yekamuri. Chikamu chemvura chiri kuenda kusimba sezvo tembiricha inodonha. Chimiro chekupedzisira chealloy chinogadziriswa. Panguva ino, iyo microstructure uye chikamu chekuumbwa kweiyo alloy inoshanduka nemamiriro ekutonhora. Kuti uvandudze alloys 'muviri uye michina zvivakwa, hunhu hwealloy hunogona kushandiswa kupisa iyo simende carbide.

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.
