Iko kukanganisa kwecemented carbide carbon content control pamhando

Iyo carbon content insimendecarbide yakadzidzwa uimba iyo vacuum sintering nzira.Ongororo iyi yakaratidza kuti iyo yakazara kabhoni yemukati mune yakabikwa zvinhu inoita basa rekuita mune kabhoni yemukati yealloy.Mukuwedzera, zvimedu zvakaoma muupfu hwakatsikirirwa zvinoumbwa panguva yekutsikirira.

Hazvisi nyore kukanganisa uye kupwanya panguva yekuita, uye iri nyore kubhuroka, zvichikonzera kuumbwa kwemaburi akavharwa panguva yemvura yechikamu sintering process, iyo ine simba rakakura pane kabhoni yemukati mu.tungsten carbide alloy, nepo huwandu hwenamo hwakawedzerwa hune diki mhedzisiro pane kabhoni yemukatisimende carbide..Sezvo tembiricha yekupisa ichiwedzera kubva pa1400 ° C kusvika 1480 ° C, iyo kabhoni yemukati mune alloy inotanga kuwedzera uye yozoderera.Kana sintering tembiricha iri 1450 ° C, iyo kabhoni yemukati inosvika pakakwirira.

Keywords: simende carbide;pressing: sintering.Mukugadzira nzira yesimende carbide, iyo kabhoni yemukati ine yakanyanya kukosha pahukuru hwezviyo zveWC, chimiro chechikamu uye mekiniki zvimiro zvesimende carbide, uye kabhoni yemukati mune mbishi zvinhu, Huwandu hweglue yakawedzerwa, kudzvanya, uye sintering zvese zvinokanganisa iyo kabhoni yemukati.Nyanzvi dzekumba nekune dzimwe nyika dzakaita tsvakiridzo yakawanda pamusoro pehukama pakati pekabhoni yemukati uye kusimba kwesimba, kuoma uye kumanikidza simba, asi zvishoma pane izvo zvinokanganisa kabhoni.Ichi chinyorwa chinoshandisa vacuum sintering nzira yekudzidza iyo kabhoni yemukati mune mbishi zvinhu., pesvedzero yeglue kusanganisa, kudzvanya uye sintering maitiro pane kabhoni
