Popanga, kulondola kwazithunzi ndi mawonekedwe azinthu zazitsulo za ufa ndizokwera kwambiri.Chifukwa chake, kuyang'anira kachulukidwe ndi kusintha kwa kachulukidwe ka ma compact panthawi ya sintering ndi nkhani yofunika kwambiri.Zomwe zimakhudza kachulukidwe ndi kusintha kwa magawo a sintered ndi:

1. Kutsika ndi kuchotsedwa kwa ma pores: Sintering imayambitsa kuchepa ndi kuchotsedwa kwa pores, ndiko kuti, kuchepetsa kuchuluka kwa thupi la sintered.

2. Mpweya wotsekedwa: Panthawi yopangira makina osindikizira, ma pores ambiri otsekedwa amatha kupangidwa mu compact, ndipo pamene voliyumu ya compact ikutenthedwa, mpweya wa ma pores akutaliwo udzakula.

3. Chemical reaction: Zinthu zina za mankhwala mu compaction ndi sintering atmosphere zimachita ndi kuchuluka kwa okosijeni mu zinthu zopangira mpweya kuti zipangitse mpweya kapena kutenthetsa kapena kukhalabe mu kuphatikizikako, kupangitsa kuti kuphatikizikako kuchepe kapena kufutukuka.

4. Alloying: Alloying pakati pa zinthu ziwiri kapena zingapo ufa.Chinthu chimodzi chikasungunuka mu chimzake kuti chipange njira yolimba, latisi yoyambira imatha kukula kapena kutsika.

5. Mafuta: Pamene ufa wachitsulo usakanizidwa ndi mafuta enaake ndi kukanikizidwa mu compact, pa kutentha kwina, mafuta osakanikirana amawotchedwa, ndipo chophatikizikacho chidzachepa, koma ngati chavunda, mpweya wa mpweya sungathe. kufika pamwamba pa compact..sintered thupi, zomwe zingachititse yaying'ono kukula.

6. Kukankhira malangizo: Panthawi sintering, kukula kwa yaying'ono kusintha perpendicularly kapena kufanana ndi kukanikiza malangizo.Nthawi zambiri, kusintha kwa mawonekedwe (radial) ndikokulirapo.Kusintha kwa dimensional mu njira yofananira (axial direction) ndi yaying'ono.
