Usoro nhazi nke MIM

Ka anyị na-aga n'ihu na-ewebata usoro ọ bụla nke teknụzụ Injection Molding Metal.

Taa, anyị ga-atụle maka sintering nke bụ isi ihe kachasị mkpa n'oge MIM.

IHE OMUME NKE MMADỤ NKE IMUME

1) Sintering bụ ikpo ọkụ na-anụ ntụ ntụ kọmpat na a okpomọkụ ala karịa agbaze ebe nke isi components, na mgbe ahụ jụrụ ya n'otu ụzọ na ọsọ, si otú ahụ na-emeziwanye ike na dị iche iche anụ ahụ na n'ibu Njirimara nke kọmpat na inweta. a ụfọdụ metallographic Ọdịdị.

2) Usoro bụ isi bụ ntụ ntụ ntụ ntụ - Nchaji ọkụ-Sintering gụnyere Preheating, Nchekwa okpomọkụ na Cooling-Firing-Sintered ngwaahịa.

3) Ọrụ nke sintering na-enweta mwepụ mmanu, metallurgical bonding, mmewere mgbasa, akụkụ mgbanwe, microstructure na ocidation mgbochi.

NKWA NKE MMALITE NKE NKE UZỌ MAMỤTA

1) Okpomọkụ dị ala na-ebute ụzọ:

Na nke a ogbo, mgbake nke metal, volatilization nke adsorbed gas na mmiri mmiri, decomposition na mwepụ nke na-akpụ gị n'ụlọnga na kọmpat.

2) Ogbo ikpo ọkụ nke etiti:

Recrystalization na-amalite n'oge a.Nke mbụ, a na-eweghachi mkpụrụ ọka kristal ahụ mebiri emebi n'ime ihe ndị ahụ ma hazie ya ka ọ bụrụ ọka kristal ọhụrụ.N'otu oge ahụ, oxides n'elu nke ahụ na-ebelata kpam kpam, na urughuru interface na-etolite a sintering olu.

3) Nchekwa anụ ihe dị elu iji wuchaa ogbo sintering:

Nke a ogbo bụ isi usoro nke sintering, dị ka mgbasa na eruba n'ụzọ zuru ezu na-aga n'ihu na nso imecha, na-akpụ a ọnụ ọgụgụ buru ibu nke mechiri emechi pores, na-aga n'ihu na-ebelata, nke mere na pre size na ngụkọta ọnụ ọgụgụ nke pores na-ebelata, na njupụta. nke sintered ahu na-budata ụba.

4) Ogbo oyi:

N'ezie sintering usoro bụ na-aga n'ihu sintering, otú usoro si sintering okpomọkụ na-eji nwayọọ jụrụ oyi ruo oge na mgbe ahụ ngwa ngwa jụrụ ruo mgbe ọkụ mmepụta eru ụlọ okpomọkụ bụkwa a ogbo ebe austenite decomposes na ikpeazụ Ọdịdị na-eji nwayọọ nwayọọ guzobe.
