Molao-motheo oa Metallurgical Powder Sintering

Mokhoa oa metallurgy oa phofo ke ho etsa lisebelisoa tse tala tsa motsoako hore e be phofo, ebe o kopanya li-powders tsena ka tekanyo e loketseng, ebe o li hatella le ho li tiisa ka sebōpeho se itseng. Li-block tsa phofo li behoa sebakeng se fokotsang, joalo ka hydrogen, ho futhumatsoa, ​​​​le sintered ho etsa motsoako. Ena ke mokhoa oa metallurgical o fapaneng ka ho feletseng le mekhoa e fetileng ea ho lahla.

Sintering joalo ka ha ho buuoa ka eona mona e ka hlalosoa feela e le ts'ebetso ea ho kopanya lithollo tsa tšepe ka ketso ea khatello le mocheso. Re sebelisa tekanyo e itseng ea khatello ho phofo ka motsoako oa motsoako ho o kopanya. Lithempereichara tse phahameng, li-powders tse haufi-ufi li khomarelana 'me butle-butle li tlatsa li-voids ho etsa alloy e phahameng haholo. Mocheso oa mocheso ka nako ena ke mocheso o qhibilihang oa karolo e tlaase ea ho qhibiliha likarolong tsa alloy. Ka hona, alloy ingot e sintered ka mocheso o ka tlase ho ntlha ea ho qhibiliha ea motsoako oohle oa phofo. Mokhoa ona o tšoana le ho kopanya mekhoa e 'meli ea ho qhibiliha le ho lahla,' me thepa ea eona e haufi le ea li-alloys. Empa ho ea ka pono ea metallographic, e lokela ho ba lekala la li-alloy castings.

Carbide e entsoeng ka samente e hlahisoa ke mokhoa ona oa metallurgy oa phofo. Ka tloaelo, li-powders tse kang tungsten, carbon, cobalt, titanium, le cerium li sebelisoa bakeng sa ho kopanya li-batch, ebe lia hatelloa le ho siloa ho etsa li-alloys. Ka hona, sehlahisoa sa ts'ebetso ena ea metallurgic e boetse e bitsoa carbide e entsoeng ka samente kapa carbide e entsoeng ka samente. Lilemong tsa morao tjena, mekhoa ea metallurgy ea phofo e tsoetse pele ka potlako haholo. Carbide, li-alloys tse nang le oli, likhokahano tsa motlakase, mabili a silang a taemane a tlamisoang ka tšepe, le lihlahisoa tse khethehileng tsa tšepe tse khabisitsoeng li etsoa ho sebelisoa mokhoa ona oa metallurgy oa phofo.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka ho le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
