socodka habka sintering carbide cemented

Isku soo wada duuboocarbide sibidhka ahwaa dareeraha wejiga sintering, taas oo ah, waxaa lagu fuliyaa iyada oo la raacayo shuruud ah in wejiga isku xidhka waa in wejiga dareere ah.Cufnaanta waxaa lagu kululeeyaa 1350C-1600C foornada faakuumka ah.Yaraynta tooska ah ee is haysta inta lagu jiro sintering waa ilaa 18%, iyo hoos u dhaca mugga waa ilaa 50%.Yaraynta saxda ah waxay kuxirantahay xajmiga walxaha budada carbide tungsten iyo ka kooban yahaycarbide sibidhka ah.

Isku soo wada duuboocarbide sibidhka ahwaa geedi socod adag oo jireed iyo kiimiko, oo ay ku jiraan ka saarista balaastiigga, degassing, sintering wejiga adag, sintering wejiga dareeraha, alloying, cufnaanta, kala diri iyo roobab, iwm The isafgaradka foomamka alaabta leh qayb ka mid ah kiimikada, qaab-dhismeedka ururka, waxqabadka iyo qaabka iyo cabbirka. xaaladaha sintayn gaar ah.Shuruudaha geeddi-socodyadani aad ayey u kala duwan yihiin iyadoo ku xiran aaladaha kala duwan ee sintering.

Carbidevacuum sintering waa habsocod sintarin ka yar 1atm (1atm=101325Pa).Sintering hoos xaaladaha vacuum waxay si weyn u yaraynaysaa caqabada cufnaanta by gaaska adsorbed on dusha budada ah iyo gaaska ku jira daloolada xiran, taas oo ku habboon habka faafinta iyo cufnaanta, iyo ka fogaansho falcelinta u dhexeeya biraha iyo xubno ka mid ah jawiga inta lagu guda jiro habka sintering.Waxay si weyn u wanaajin kartaa qoyaanka wejiga isku xidhka dareeraha ah iyo wejiga adag, laakiin waa in taxaddar la sameeyaa si looga hortago uumiga luminta kobalt inta lagu jiro vacuum sintering.Vacuum sintering guud ahaan waxaa loo qaybin karaa afar marxaladood, kuwaas oo ah marxaladda saarista balaastikada, marxaladda hore-sintering,carbide tungstenheerkul sare oo heerkul sare ah, iyo heer qaboojin.
