Powder Metal Manufacturing (PMM)
Selelekela sa Powder Metal Manufacturing
Powder Metal Manufacturing (PMM) e emela mokhoa o hloekisitsoeng le o rarahaneng oa ho hlahisa likarolo tsa tšepe tsa boleng bo phahameng, tse rarahaneng. Ts'ebetso ena e kenyelletsa ho kopana ha tšepe e phofshoana e khabane e lateloang ke ho futhumatsa (sintering) ho etsa lisebelisoa tse tiileng, tse teteaneng tse nang le lisebelisoa tse ntlafalitsoeng tsa mochini. PMM e bohlokoa mafapheng a fapaneng a kang likoloi, sefofane, le lisebelisoa tsa bongaka bakeng sa ts'ebetso ea eona le ho baballa litšenyehelo.
Kakaretso ea Powder Metal Manufacturing
Powder Metallurgy ke eng?
Metallurgy ea phofoke mokhoa oa ho etsa masela moo litšepe tsa tšepe li kopanngoang ka hloko ho ba libopeho tse lakatsehang ebe li siloa ho fihlela matla le botšepehi. Mokhoa ona o lumella taolo e nepahetseng holim'a thepa ea thepa le lijeometri tsa sehlahisoa sa ho qetela, ho feta tlhoko ea ho qhibiliha le ho lahlela litšepe.
Semelo sa Histori
Ho tloha lilemong tse likete tse fetileng, metallurgy ea phofo e fetohile ho tloha mofuteng oa bonono ho ea ho theknoloji ea bohlokoa ea indasteri. Tsoelopele ea sejoale-joale e qalile ka matla lilemong tsa bo-1930, e susumetsoa ke tlhokahalo e ntseng e eketseha ea indasteri ea likarolo tsa tšepe tse nepahetseng le tse tšepahalang.
Lisebelisoa tse tala le phofo
Mefuta ea Litšepe Tse Sebelisitsoeng
Litšepe tse sebelisoang hangata ho PMM li kenyelletsa tšepe, koporo, tšepe e sa hloekang, titanium le li-alloys tse fapaneng, e 'ngoe le e' ngoe e khethiloe ho ipapisitse le thepa e itseng joalo ka ho hanyetsa kapa ho tsamaisa mocheso.
Ho Lokisetsa Metal Powders
Metal powders e hlahisoa ka atomization, phokotso ea lik'hemik'hale, kapa electrolysis, mokhoa o mong le o mong o susumetsa litšoaneleho tsa phofo joalo ka boholo ba karolo, sebopeho le bohloeki. Litšobotsi tsena li bohlokoa kaha li ama ka kotloloho boits'oaro ba phofo nakong ea compaction le sintering.
Mokhoa oa Powder Metallurgy
Ho kopanya le ho kopanya
Metal powders e kopantsoe le li-binders le lubricant ho thusa ho kopana le ho etsa bonnete ba ho lumellana ha sehlahisoa sa ho qetela. Mohato ona ke oa bohlokoa bakeng sa ho fihlela thepa e ts'oanang ea mochini ho pholletsa le karolo e entsoeng.
Compacting le Sintering
Compaction e kenyelletsa ho hatella phofo hore e be hlobo tlas'a khatello e phahameng ho etsa karolo e 'tala', e ntan'o tšeloa ka sebōping se laoloang sa sepakapaka. Sintering e kopanya likaroloana tsa tšepe hammoho ka tlas'a ntlha ea tsona ea ho qhibiliha, e leng ho ntlafatsa boleng ba sebopeho sa karolo le matla.
Ts'ebetso ea bobeli
Ka mor'a ho sintering, likarolo tse ngata li etsoa opereishene ea bobeli joalo ka mochini, ho phekola mocheso, le ho qeta bokaholimo ho fihlela litlhoko tse ikhethang tsa boenjiniere. Lits'ebetso tsena li etselitsoe ho ntlafatsa likarolo tsa ts'ebetso, joalo ka ho hanyetsa ha tsona kapa ho nepahala ha likarolo.
Lits'ebetso tsa likarolo tsa Powder Metal
Lisebelisoa tsa indasteri
PMM e sebelisoa haholo indastering ea likoloi ho etsa likarolo tse rarahaneng tse kang likere le lik'hamera, tse ruang molemo ho bokhoni ba ts'ebetso ea ho hlahisa likarolo tse matla, tse nepahetseng moruong. Lisebelisoa tsa Aerospace le tsona li phahamisa PM bakeng sa likarolo tsa bohlokoa, tse bobebe tse khomarelang litekanyetso tse thata tsa ts'ebetso.
Likarolo tse Tloaelehileng
Ka lebaka la ho feto-fetoha ha maemo, PMM e ts'ehetsa ho theoa ha likarolo tse ikhethileng tse etselitsoeng lits'ebetso tse ikhethileng, haholo indastering ea theknoloji e phahameng joalo ka tlhahiso ea lisebelisoa tsa bongaka, moo likarolo tse ikhethileng tsa biocompatible li leng bohlokoa.
Melemo ea Powder Metal Manufacturing
Litšenyehelo-Ka katleho
PMM e fokotsa haholo litšila le tšebeliso ea matla ha e bapisoa le mekhoa e tloaelehileng ea ho sebetsa ka tšepe, e fanang ka chelete e ngata ea ho boloka litšenyehelo, haholo-holo maemong a phahameng a tlhahiso.
Ho nepahala ho Phahameng le ho Itloaetsa
Ts'ebetso ea PM e tsebahala ka bokhoni ba eona ba ho hlahisa libopeho tse rarahaneng tse nang le mamello e thata, ho fokotsa tlhoko ea ho latela machining le tšenyo ea thepa.
Melemo ea Tikoloho
Hangata ho nkoa e le thekenoloji e tala, PMM e fokotsa litšila le tšebeliso ea matla, e khothalletsang mekhoa e tsitsitseng ea ho etsa lihlahisoa ka har'a indasteri.
Qetello
Powder Metal Manufacturing ke karolo ea bohlokoa ea tikoloho ea sejoale-joale ea tlhahiso, e tsebahalang ka ho nepahala, ts'ebetso le ts'ebetso ea eona e tsitsitseng. Ha liindasteri li ntse li tsoela pele ho batla litharollo tsa tlhahiso e ncha le tse baballang chelete e ngata, PMM e lebelletsoe ho hola le ho fetoha, ho ntlafatsa ts'ebetso ea eona e seng e ntse e le kholo tlhahisong ea indasteri.
Sengoliloeng sena se entsoe ka makhethe ho fana ka kutloisiso e felletseng ea Powder Metal Manufacturing, e totobatsang lits'ebetso tsa eona, lits'ebetso le melemo ho totobatsa bohlokoa ba eona lefapheng la kajeno la indasteri.
