Ukuqulunqwa kwezixhobo ze-alloy tool

Izixhobo zesixhobo se-alloy zenziwe nge-carbide (ebizwa ngokuba yi-hard phase) kunye nentsimbi (ebizwa ngokuba yi-binder phase) enobunzima obuphezulu kunye nendawo yokunyibilika ngomgubo wesinyithi. Apho izixhobo ze-alloy carbide izixhobo ezisetyenziswa ngokuqhelekileyo zine-WC, i-TiC, i-TaC, i-NbC, njl., izibophelelo eziqhelekileyo ezisetyenziswayo ziyi-Co, i-titanium carbide-based binder yi-Mo, Ni.

 

Iimpawu ezibonakalayo kunye noomatshini bezixhobo zesixhobo se-alloy zixhomekeke ekubunjweni kwe-alloy, ubukhulu bepowder particles kunye nenkqubo ye-sintering ye-alloy. Izigaba ezinzima kakhulu ezinobunzima obuphezulu kunye neqondo eliphezulu lokunyibilika, ukuphakama kobunzima kunye nobunzima obuphezulu beqondo lokushisa kwesixhobo se-alloy Okukhona i-binder, iphezulu amandla. Ukongezwa kwe-TaC kunye ne-NbC kwi-alloy kunenzuzo ekucoceni iinkozo kunye nokuphucula ukuxhathisa ukushisa kwe-alloy. I-carbide ene-cemented esetyenziswa ngokuqhelekileyo iqulethe inani elikhulu le-WC kunye ne-TiC, ngoko ke ubunzima, ukuxhathisa ukugqoka kunye nokuchasana Ukumelana nobushushu kuphezulu kunoko kwensimbi yesixhobo, ukuqina kweqondo lokushisa yi-89 ~ 94HRA, kunye nokumelana nobushushu yi-80 ~ 1000 degrees.
