I-metallurgy yomgubo yinkqubo yokwenza umgubo wesinyithi okanye ukusebenzisa umgubo wesinyithi (okanye umxube womgubo wesinyithi kunye nomgubo ongeyontsimbi) njengezinto ezikrwada, ukubunjwa kunye ne-sintering, kunye nokwenza izinto zetsimbi, izinto ezidibeneyo kunye neentlobo ezahlukeneyo zeemveliso.Indlela yesinyithi yomgubo kunye nokuveliswa kweeseramics zineendawo ezifanayo, zombini ziyi-teknoloji ye-powder sintering, ngoko ke, uchungechunge lweteknoloji entsha ye-metallurgy ingasetyenziselwa ukulungiswa kwezinto ze-ceramic.Ngenxa yeenzuzo zetekhnoloji ye-powder metallurgy, iye yaba sisitshixo sokusombulula ingxaki yezinto ezintsha, kwaye idlala indima ebalulekileyo ekuphuhliseni izinto ezintsha.

Ke luhlobo luni lotshintsho olwenzekileyo ukusuka kumgubo wesinyithi wesintu ukuya kwimetalurgy yale mihla?

1. Ukwahluka kobugcisa

Itekhnoloji yemveli yomgubo wesinyithi ikakhulu ngokubumba umgubo kunye nokuthambisa okuqhelekileyo.Ubuchwephesha bemetalurgy yomgubo wanamhlanje Indlela yenkqubo yokwenza kunye nokuntywila izixhobo zetsimbi okanye iinxalenye zomatshini ezenziwe ngomgubo wesinyithi, onokwenziwa ngokuthe ngqo ngaphandle kokucubungula.Iimveliso zinokulungiswa nge-laser sintering, i-microwave sintering kunye noxinzelelo olushushu lwe-isostatic lomgubo.

2. Izinto ezahlukeneyo zokulungiselela

I-metallurgy ye-powder yendabuko inokwenza kuphela izinto eziqhelekileyo ze-alloy, ezifana nensimbi engenasici kunye ne-aluminium alloy, enempahla ephantsi.I-metallurgy yale mihla yomgubo inokuvelisa iintlobo ngeentlobo zezinto zokwakha ezisebenza kakhulu kunye nezinye izinto ezikhethekileyo.Umzekelo, iipowder superalloys, umgubo wentsimbi, ialloys yesiseko sesinyithi, ubushushu obuphezulu bezinto zokuqhuba, iicomposites zeceramic matrix, nanomaterials, isiseko sentsimbi, icobalt chromium alloy materials.

3. Itekhnoloji yolungiselelo oluphezulu

Iincinci zepowder ezilungiselelwe yiteknoloji yokulungiselela umgubo wendabuko bunzima kwaye ubungakanani bepowder abufani.Itekhnoloji yale mihla yokulungisa i-metallurgy ibandakanya itekhnoloji yokubekwa kwejethi, itekhnoloji yokunyibilikisa i-electron beam laser, njl. njl., kwaye umgubo olungisiweyo uncinci kwaye uchaneke ngakumbi.

4. Iimveliso zokubumba

Itekhnoloji yomgubo wesinyithi wesintu iprinta iimveliso ezirhabaxa noko, kunye noshicilelo olukrelekrele lwamalungu amakhulu aneenkqubo ezilula.Amalungu alungiselelwe yitekhnoloji ye-powder metallurgy yanamhlanje anzima ngakumbi, kungekuphela nje imilo eguqukayo, kodwa kunye nobukhulu kunye neemfuno zomgangatho zichaneke ngakumbi.Umda obanzi wosetyenziso.
