Ukusebenza okuhlukahlukene kwezobuchwepheshe be-pulverizing ku-powder-metallurgy

Ubuchwepheshe obushesha bokusimamisa impuphu nobuchwepheshe be-pulverization buqonde ngqo, okungukuthi, izinsimbi eziwuketshezi noma ama-alloys achotshoziwe futhi ajijiswa ngokushesha ukuthola izinto eziyimpuphu. Lolu hlobo lobuchwepheshe bokugaya lunganciphisa ngempumelelo ukwahlukaniswa kwezingxenye ze-alloy, ngakho-ke izingxenye ze-alloy powder ezitholakele ziyafana.

Ngenxa yemidiya ehlukile yokwenziwa kwe-atomization esetshenzisiwe, kukhona nezindlela ezahlukahlukene zokukhetha ukwenziwa kwe-atomization ezisetshenziswa kubuchwepheshe be-metallurgy technology, njenge-atomization yemifudlana emibili, i-atomization yegesi, i-atomization yamanzi ephezulu, i-centrifugal atomization, ne-vacuum atomization. Ku-atomization yemifudlana emibili, lapho i-atomizing medium kanye nokugeleza ketshezi lensimbi kukhishwa ngombhobho, ukugeleza okubili kuketshezi kuyashayisana, ngaleyo ndlela kuchoboze ukugeleza ketshezi bese kufuthwa impuphu.

Indlela yokwenza igesi ngokuvamile idinga ingcindezi yegesi engu-2 kuye ku-8 MPa. Ngalesi sizathu, izinhlayiya ze-powder ezinezindawo ezibushelelezi zingasetshenziswa ku-powder metallurgy. Indlela yokwenziwa kwamanzi isebenzisa amanzi ngobuningi obuphakeme njengendawo yokwenza i-atomization, ngakho-ke isivinini se-condensation esifinyelelwe siphezulu nge-oda lobukhulu kunendlela ejwayelekile yokwenza igesi, ngakho-ke ukwakheka kwempuphu ngokuvamile akujwayelekile.

Ubuchwepheshe be-Mechanical alloying pulverization yindlela yokulungiselela i-alloy powder noma i-powder eyinhlanganisela kusuka ku-powder elemental. Iphothulwa endaweni yokugaya ibhola elinamandla amakhulu futhi idinga isikhathi eside ukugaya phakathi kwezinhlayiya ze-powder naphakathi kwezinhlayiya ze-powder namabhola okugaya. Impuphu iphukile futhi idabukile.

Ungakhohlwa ukuthi kukhona nobuchwepheshe bokulungiselela i-ultrafine powder ku-powder metallurgy. Ngenxa yobukhulu bezinhlayiyana ezincane, izimpushana ezikhiqizwa yilobu buchwepheshe zinezici ezihluke kakhulu zomzimba, zamakhemikhali nezomshini.
