He aha te hangarau whakarewa paura?

I whakamahia tuatahi te hangarau whakarewa i roto i te United States i te tau 1870. I whakamahia e ia he paura whakarewa hei rauemi mata, katahi ka pehia nga peera koranu parahi-arahi kia mohio ai te hangarau whakahinuhinu whaiaro o te whanau, me te whakaputa i nga momo waahanga me nga waahanga ma te pehi. me te whakahiato.Ko te tukanga hangarau whakarewa paura he ahua tauhou ki te katoa, engari ki te whai muri i taku whakamaramatanga, ka ngawari ki a koe te mohio.

Ko te tukanga taketake o te hangarau metallurgy paura
Ko te mea matua he paura rino pai, katahi ka taapirihia te paura ki te pokepokea e hiahiatia ana, katahi ka hangaia te tauira ma te (whangai) te pehanga ranei, ka mutu ko te waahanga me te paanga e hiahiatia ana ka taea ma te sintering.Ko etahi waahanga e hiahia ana ki te tukatuka i muri.

He aha te rereketanga o nga waahanga whakarewa MIM me te PM paura?
1: Ko te whakarewatanga o te whakarewanga whakarewa
I whanau mai te whakarewanga werohanga paura i California i te tau 1973, e kiia ana ko MIM.He momo hou o te hangarau whakarewa whakarewa paura i hangaia ma te whakakotahi i te hangarau whakarewa werohanga kirihou me te mara whakarewa paura.He tata tonu te mahi whakakikorua i te whakarewanga whakarewa paura ki te hangarau whakarewa paura.Tuatahi, ka whakakotahihia te paura totoka me te kaapiri kaiao, katahi ka whakamahana me te kirihou i te pāmahana teitei o te 150 nga nekehanga.Ka whakamahia nga taputapu whakakikorua ki te wero i te pokepokea ki roto i te rua, katahi ka whakakaha me te hanga.Ko te tikanga whakapoapoa ka tango i te herenga i roto i te waahi kua oti te hanga, ka mutu, penei i te whakarewa paura, ka puta nga waahanga tika ma te sintering.

2: Paura metallurgy pehi
Ko te whakaki i te pokepokea ki te paura ma te kaha, ka peia e te pehanga miihini.Ko tetahi o nga mea tino whakamahia i roto i nga mahi ahumahi.Ko te pehi maakaa rino kua hirihia e te makariri, te pehi isostatic makariri, te pehi isostatic wera, me te pehi mahana kei te hanga perehi katoa.Heoi, na te mea ka taea anake te pehi ki runga me raro ki nga taha e rua, kaore e taea te whakaputa i etahi waahanga hangahanga uaua, ka taea ranei te hanga kia noho kore noa.

He maha nga waahanga e whakamahi ana i te hangai werohanga, i te hangai whakakoi ranei, a ka rereke nga waahanga whakamutunga.Mena kare tonu koe e tino mohio, kaua e mangere ki te whakapiri mai ki a maatau Jingshi New Materials mo te korerorero.
