Lisebelisoa tsa Powder Metal ke Life?

Lisebelisoa tsa Powder Metal ke Life? Likarolo tsa tšepe tsa phofo li etsoa ka tšepe ea phofo kats'ebetso e ikhethang e tsejoang ka hore ke phofo ea metallurgy. Mokhoa ona o kenyelletsa ho petetsa le ho sila phofo ea tšepe ho hlahisa likarolo tse rarahaneng, tse nepahetseng haholo.

Metallurgy ea phofoe hlokomeleha ka bokhoni ba eona ba ho theha lijeometri tse rarahaneng le ho kopanya likaroloana tse ngata ho karolo e le 'ngoe, e kopaneng. Sena ha se fokotse litšenyehelo tsa kopano feela empa hape se ntlafatsa botšepehi ba sebopeho.

Liindasteri tse kang tsa makoloi, sefofane, le tlhokomelo ea bophelo bo botle li ntse li tsoela pele ho amohela likarolo tsena ka lebaka la ts'ebetso ea tsona e sebetsang le ho feto-fetoha ha maemo. Ho feta moo, ts'ebetso e khothaletsa tlhahiso e tsitsitseng ka ho fokotsa litšila le ho baballa matla.

Likaroloana tsa Powder Metal li Etsoa Joang?

Ho theha likarolo tsa tšepe tsa phofo ho kenyelletsa ts'ebetso e nepahetseng, e nang le mehato e mengata e netefatsang liphello tsa boleng bo phahameng. E-re ke u tsamaee ka mekhahlelo ea bohlokoa.

Tlhahiso ea Phofo le Motsoako

Leeto le qala ka ho hlahisa phofo ea tšepe. Baetsi ba sebelisa mekhoa e kang atomization, sila, kapa metsoako ea lik'hemik'hale ho etsa likaroloana tsa tšepe tse ntle. Joale li-powders tsena lia kopanngoa le ho kopanngoa ho finyella thepa e lakatsehang. Ho kopanya ho kopanya li-powders tsa lik'hemik'hale tse fapaneng, ha ho kopanya ho tiisa ho tšoana ka boholo le sebopeho. Mohato ona o bohlokoa hobane ke oona o khethollang litšobotsi tsa karolo ea ho qetela, tse kang matla le ho tšoarella.

Mokhoa oa ho kopanya

Ka mor'a moo ho latela mokhoa oa ho kopanya, moo phofo e kopantsoeng e bang teng. Ke bone mohato ona o sebelisa mekhoa e kang die compaction, cold isostatic pressing (CIP), kapa hot isostatic pressing (HIP). Ka mohlala, die compaction e sebelisa punch ho hatella phofo hore e be hlobo, e etsa "compact e tala." CIP e sebelisa khatello ka mokhoa o ts'oanang ho tsoa mahlakoreng 'ohle, e etsa hore e lokele libopeho tse rarahaneng. Ho boloka khatello e tsitsitseng nakong ena ho tiisa hore likaroloana li tlamahane ka mochine, e leng se hlahisang sebopeho se teteaneng le se ts'oanang.

Sintering le ho qetela Processing

Mohato oa ho qetela kesintering, moo phofo e kopantsoeng e futhumatsoang ka tlas'a ntlha ea eona ea ho qhibiliha. Mokhoa ona o kopanya likaroloana, ho etsa karolo e tiileng. Lintho tse kang nako, mocheso le sepakapaka li phetha karolo ea bohlokoa mona. Linako tse telele tsa sintering li ntlafatsa ho kopana ha likaroloana, ha sepakapaka se laoloang se thibela oxidation. Ka mor'a ho sintering, mekhoa e meng e kang phekolo ea mocheso kapa ho kenella ka hare ho eona e ntlafatsa thepa ea karolo, joalo ka matla le boima.

Ka ho latela mehato ena, bahlahisi ba hlahisa likarolo tse phahameng tse nepahetseng tse nang le litšila tse fokolang. Ts'ebetso ena e totobatsa hore na hobaneng metallurgy ea phofo e ratoa bakeng sa liindasteri tse batlang ts'ebetso le ts'ebetso e tsitsitseng.

Sebakeng sa sefofane le ts'ireletso, likarolo tsa tšepe tsa phofo li fihlela litlhoko tse thata bakeng sa matla, ho tšoarella le ho nepahala. Lisebelisoa tsa bohlokoa li kenyelletsa:

• Maqhubu a turbine: E entsoe ka Al-SiC MMC, mahare ana a fokotsa boima ba sefofane le ho ntlafatsa ts'ebetso ea mafura.
• Likarolo tsa Enjene: Likamore tse tukang le li-nozzles tsa mafura li rua molemo molemong oa ho hanyetsa mocheso o phahameng le meralo e rarahaneng.
• Lifofane tsa Brake Pads: Lisebelisoa tsena li mamella meroalo le mocheso o feteletseng lifofaneng tsa sesole le tsa sechaba.
• Thermal Spray Coatings: E sebelisoa ho lienjineri, liphahlo tsena li eketsa nako ea bophelo ea likarolo tsa bohlokoa.
• Lisebelisoa tse bobebe: Metallurgy ea phofo e thusa ho hlahisa likarolo tse bobebe, ho fokotsa tšebeliso ea mafura le ho ntlafatsa ts'ebetso.

Liindasteri tsa lifofane le ts'ireletso li nkile karolo e fetang 51% ea lekeno la 'maraka oa metallurgy ka 2022, e totobatsang tlhoko e ntseng e hola ea lisebelisoa tse tsoetseng pele.

Lisebelisoa tsa Bongaka le Lihlahisoa tsa Bareki

Likarolo tsa tšepe tsa phofo le tsona li kenya letsoho haholo ho ntlafatso ea lihlahisoa tsa bongaka le tsa bareki.

Lihlahisoa tsa bareki, metallurgy ea phofo e nolofalletsa ho theha likarolo tse qaqileng, tse rarahaneng ka ho nepahala ho phahameng. Mekhoa e kangho bopa ente ea tšepe(MIM) le tlhahiso ea li-additive (AM) li lumella bahlahisi ho hlahisa li-geometri tse rarahaneng ka katleho. Ho tloha ho li-bearings tse itšebetsang ho ea ho lisebelisoa tsa elektronike tsa morao-rao, likarolo tsa tšepe tsa phofo li ntse li tsoela pele ho theha mekhoa e mecha ea letsatsi le letsatsi.

Likarolo tsa tšepe tsa phofo li fana ka melemo e ke keng ea lekanngoa ho pholletsa le liindasteri. Ba fokotsa litšenyehelo ka 70%, ba fokotsa litšila tsa thepa, 'me ba nolofalletsa meralo e rarahaneng ka nepo e ikhethang. Baetsi ba rua molemo ka bokhoni ba bona ba ho hlahisa likarolo tsa boleng bo phahameng ka ho nepahala ho tsitsitseng ha ba ntse ba felisa mekhoa e mengata ea bobeli. Likarolo tsena li boetse li tšehetsa botsitso ka ho sebelisa feela thepa e hlokahalang bakeng sa tlhahiso.
