Muchidimbu sumo ye sintering process ye iron-copper-based MIM zvikamu

Kufuridzirwa kwe sintering process parameters pakuita kwesimbi-based parts Sintering process paramita: sintering tembiricha, sintering nguva, kupisa uye kutonhora kumhanya, sintering mamiriro, nezvimwe.

1. Sintering tembiricha

Kusarudzwa kwekupisa kwekupisa kwesimbi-yakavakirwa zvigadzirwa kunonyanya kuenderana nekuumbwa kwechigadzirwa (kabhoni yemukati, alloy element), mashandiro ekuita (mechanical zvivakwa) uye mashandisiro (zvimiro zvikamu, anti-friction zvikamu), nezvimwe.

2. Sintering nguva

Sarudzo yenguva yekupisa yesimbi-yakavakirwa zvigadzirwa zvinonyanya kuenderana nekugadzirwa kwechigadzirwa (kabhoni yemukati, alloy elements), uremu hweyuniti, saizi yejometri, ukobvu hwemadziro, density, nzira yekurodha choto, nezvimwewo;

Iyo sintering nguva inoenderana nekupisa kwe sintering;

Iyo yakawanda sintering nguva ndeye 1.5-3h.

Muchoto chinoenderera, kubata nguva:

t = L/l ▪n

t - Kubata nguva (min)

L- kureba kwebhandi rakaiswa (cm)

l - Kureba kwechikepe chinopisa kana graphite board (cm)

n - chikepe chekusunda nguva (min/chikepe)

3. Kupisa uye kutonhora kwehuwandu

Iyo yekupisa mwero inokanganisa kukurumidza kwekuputika kwemafuta, nezvimwewo;

Mwero wekutonhora unobata microstructure uye kushanda kwechigadzirwa.
