Ts'ebetso ea sintering ea MIM

Ha re tsoeleng pele ho hlahisa ts'ebetso e 'ngoe le e' ngoe ea theknoloji ea Metal Injection Molding.

Kajeno re tla tšohla ka sintering e leng lintlha tsa bohlokoa ka ho fetisisa nakong ea MIM.

TSEBO EA MOTHEO E TS'OA

1) Sintering ke ho futhumatsa le ho utloa phofshoana ea phofo ka mocheso o tlase ho feta ntlha ea ho qhibiliha ea likarolo tsa eona tse kholo, ebe o e pholisa ka tsela e itseng le lebelo, ka tsela eo e ntlafatsa matla le mefuta e fapaneng ea 'mele le ea mechine ea compact le ho fumana. sebopeho se itseng sa metallographic.

2) Ts'ebetso ea mantlha ke Powder compact-Furnace Charging-Sintering ho kenyelletsa Preheating, Heat Preservation and Cooling-Firing-Sintered products.

3) Mosebetsi oa sintering ke ho tlosa lubricant, metallurgical bonding, element diffusion, dimensional changes, microstructure le thibelo ea ocidation.

KELELLO E MKHUTANE EA MOKHOA OA HO SINTERING

1) Mocheso o tlase Mokhahlelo oa pele ho sintering:

Mothating ona, ho hlaphoheloa ha tšepe, ho ferekana ha khase le mongobo, ho bola le ho tlosoa ha moemeli ka har'a komporo.

2) Mocheso o mahareng oa ho futhumatsa sethala sa sintering:

Recrystallization e qala sethaleng sena.Ntlha ea pele, lithollo tsa kristale tse holofetseng li tsosolosoa ka har'a likaroloana ebe li hlophisoa bocha hore e be lithollo tse ncha tsa kristale.Ka nako e ts'oanang, li-oxide tse holim'a likaroloana li fokotsehile ka ho feletseng, 'me sebopeho sa likaroloana se etsa molala oa sintering.

3) Ho boloka nako e phahameng ea nako ea ho utloa ho phethela sethala sa sintering:

Mokhahlelo ona ke ts'ebetso e kholo ea sintering, joalo ka ho hasana le ho phalla ka botlalo ho tsoela pele le haufi le ho phethoa, ho etsa palo e kholo ea li-pores tse koetsoeng, le ho tsoela pele ho fokotseha, e le hore boholo ba pele le palo eohle ea li-pores li fokotsehe, 'me boima ba 'mele bo fokotsehe. 'mele oa sintered o eketseha haholo.

4) Sethala sa ho pholisa:

Mokhoa oa sebele oa sintering ke o tsoelang pele oa sintering, kahoo ts'ebetso ho tloha mocheso oa sintering ho lieha ho pholile ka nako e itseng ebe ho pholile ka potlako ho fihlela tlhahiso ea sebōpi e fihla mocheso oa kamore e boetse ke sethala moo austenite e senyehang 'me mohaho oa ho qetela o thehoa butle-butle.

Ho na le lintlha tse ngata tse susumetsang ho ama ts'ebetso ea sintering.Le lintlha tse kenyelletsang mocheso, nako, sepakapaka, sebopeho sa thepa, mokhoa oa alloy, litaba tsa lubricant le ts'ebetso ea sintering joalo ka sekhahla sa ho futhumatsa le ho pholisa.Ho ka bonoa hore sehokelo se seng le se seng se na le tšusumetso ea bohlokoa boleng ba sintering.Bakeng sa lihlahisoa tse nang le mehaho e fapaneng le li-powders tse fapaneng, li-parameter tse fapaneng li hloka ho fetoloa.
