Fa'atomuaga pu'upu'u o le fa'agasologa o le sintering o vaega MIM fa'avae u'amea

O le a'afiaga o fa'asologa o fa'asologa o le sintering i le fa'atinoga o vaega fa'avae u'amea Fa'asologa o le fa'agasologa o le sintering: sintering temperature, sintering time, fa'avevela ma le saosaoa malulu, sintering atmosphere, etc.

1. Sintering vevela

O le filifilia o le vevela o le sintering o oloa faʻavae uʻamea e faʻavae i luga o le gaosiga o oloa (carbon content, alloy elements), manaʻoga faʻatinoga (mea faʻainisinia) ma faʻaoga (vaega faʻavae, vaega anti-friction), ma isi.

2. Taimi fa'amau

O le filifiliga o le taimi sintering mo oloa faʻavae uʻamea e faʻavae i luga o le gaosiga o oloa (carbon content, elemene uʻamea), iunite mamafa, geometric size, mafiafia puipui, density, auala faʻapipiʻi ogaumu, ma isi;

O le taimi faʻafefete e fesoʻotaʻi ma le vevela o le sintering;

O le taimi faʻapipiʻi masani e 1.5-3h.

I le ogaumu faifai pea, taimi taofi:

t = L/l ▪n

t — Taimi taofi (min)

L— umi ole fusipa'u (cm)

l - Umi ole va'a mu po'o laupapa kalafi (cm)

n - va'a tulei va'a (min/vaa)

3. Fa'avevela ma fa'alili le fua

O le fua faʻavevela e aʻafia ai le saoasaoa o le volatilization o lubricants, ma isi;

Ole fua ole malulu e a'afia ai le microstructure ma le fa'atinoga o le oloa.
