Iindlela zeSintering zeMetallurgy yomgubo (umgubo we-metallurgy sintering)
Iindlela zokucofa i-powder metallurgy zibandakanya oku kulandelayo:
I-metallurgy yomguboifuna uthotho lwamanyathelo enkqubo afana nokuveliswa komgubo, ukucinezela, ukucofa, kunye nokulungiswa kwangemva. Phakathi kwazo, i-powder metallurgy sintering yinkqubo yonyango lobushushu obuphezulu obudibanisa ngakumbi i-compact okanye imizimba engumgubo ekhululekileyo ukuphucula amandla kunye nezinye iimpawu. Nangona kunjalo, ngenxa yomahluko, iindlela zokugalela i-powder metallurgy nazo zohlulwe zibe ziindidi ezininzi.
1. Isigaba solwelo sintering
Ukuba kukho amacandelo amabini okanye ngaphezulu kwi-powder compact, i-sintering inokwenziwa ngaphezu kwendawo yokunyibilika yecandelo elithile, ngoko ke inani elincinci lesigaba solwelo libonakala kwi-powder compact ngexesha lokucoca.
2. Ukunciphisa uxinzelelo
Ngexesha le-sintering, uxinzelelo lusetyenziswa kumzimba ongumgubo ukukhuthaza inkqubo yoxinaniso. Uxinzeleloukuculangamanye amaxesha kufana nokucofa okushushu, okuyinkqubo edibanisa ukubunjwa kunye nokucwiliswa komgubo ukufumana iimveliso ngokuthe ngqo.
3. Ukuqalisa sintering
Kwinkqubo ye-sintering, imilinganiselo ethile yomzimba okanye yeekhemikhali yamkelwe ukunciphisa kakhulu ukushisa kwe-sintering kunye nokunciphisa ixesha lokucoca, ngelixa ukusebenza komzimba odibeneyo kuphuculwe kwaye kuphuculwe.
4. EDM sintering
Xa i-powder body iqulunqwa kwaye icinezelwe, umbane ochanekileyo kunye nombane we-pulse usetyenziselwa ukuvelisa i-arc phakathi kweengcezu ze powder for sintering; ngexesha le-sintering, uxinzelelo lusetyenziswa ngokuthe ngcembe kwi-workpiece, kunye neenkqubo ezimbini zokubumba kunye ne-sintering zidibene.
Imixholo eyaziswa ngasentla ziindlela ezine eziqhelekileyo zomgubo wesinyithi. Ngokusebenzisa ezi ndlela sintering, inkqubo umgubo metallurgy sintering ingagqitywa ngempumelelo. Kuba, kwinkqubo ye-powder metallurgy sintering, amasuntswana omgubo atyhubela iinkqubo zomzimba kunye neekhemikhali ezifana nokuhamba ngokufanayo, ukusasazwa, ukunyibilika, kunye nokuhlaziywa kwakhona, ukuze umzimba womgubo uxineke ngakumbi kwaye ezinye okanye zonke iipores zipheliswe.
