Ukungeniswa Inkqubo yomgubo wesinyithi

I-powder compact idityaniswe nesinyithi se-liquid okanye ifakwe kwi-metal metal, i-pores kwi-compact izaliswe ngetsimbi ye-liquid, kwaye i-compact material or parts ifunyenwe ngokupholisa phantsi.Le nkqubo ibizwa ngokuba kukuntywiliselwa.Inkqubo yokuntywiliselwa ixhomekeke kwisinyithi esinyibilikisiweyo sangaphandle ukuze simanzise umgubo womzimba.Ngaphantsi kwesenzo samandla e-capillary, isinyithi se-liquid sihamba kunye ne-pores phakathi kwee-particles okanye ii-pores ngaphakathi kwee-particle de ii-pores zizaliswe ngokupheleleyo.

Izinto eziluncedo zokungeniswa kobhedu kwezixhobo ezisekwe kwintsimbi yomgubo:
1. Ukuphucula iimpawu zoomatshini;

2. Ukuphucula ukusebenza kwe-electroplating;

3. Ukuphucula ukusebenza kwebrazing;

4. Ukuphucula ukusebenza koomatshini;

5. Ukuphucula ukuhanjiswa kombane kunye ne-thermal;

6. Kulula ukulawula ubungakanani bamacandelo;

7. Yiba nokusebenza kakuhle kokutywinwa koxinzelelo;

8. Amacandelo amaninzi anokudityaniswa;

9. Ukuphucula umgangatho wokucima;

10. Ukungeniswa kwendawo yeengxenye ezikhethekileyo ezifuna ukuqiniswa kunye nokuqina kweempawu.

Imiba yempembelelo:

1. Ukuxinana kwamathambo
Njengoko i-skeleton density inyuka, amandla ensimbi ene-sintered yobhedu ayanda kakhulu, kwaye ubunzima buyanda.Oku kubangelwa ukunyuka kwe-skeleton density, ukunyuka kwexabiso le-pearlite, kunye nomxholo wobhedu ophantsi.Ngokumalunga neendleko, ukukhetha ubuninzi be-skeleton ephezulu kunokunciphisa umxholo wobhedu, ngaloo ndlela kuphuculwe inzuzo yezoqoqosho.

2. Yongeza isiqalelo Sn
Ukongezwa kwendawo encibilikayo ephantsi ye-Sn kunenzuzo ekunyuseni ukuxinana kunye namandla ensimbi ene-sintered yobhedu.Ukusuka kumzobo wesigaba se-alloy Cu-Sn, kunokubonwa ukuba ii-alloys zethusi eziqukethe i-Sn zineqondo lokushisa eliphantsi lokubunjwa kwesigaba solwelo, elinokukhuthaza ukungenwa kakuhle kwee-alloys zethusi.

3. Ubushushu
Njengoko iqondo lokushisa linyuka, izinga lokunyuka kweenkozo nalo liyanda, eliyingozi ekuphuculeni amandla.Ngoko ke, ukungena ngokufanelekileyo kwe-sintering kunye nexesha lokubamba kufuneka kukhethwe phantsi kwesiseko sokuqinisekisa i-alloying epheleleyo kunye ne-homogenization ye-Fe-C, ukungena ngokupheleleyo kwe-Cu, kunye nokuqiniswa kwesisombululo esiqinileyo se-Fe-Cu.
