Kedu ihe bụ metal powder sintering?

Na metallurgy ntụ ntụ,ntụ ntụ metallurgy n'ichepụta usoroma ọ bụ jiri ya dị ka ihe eji eme ihe iji mepụta ihe ọla, ihe ndị mejupụtara, na ngwaahịa dị iche iche mgbe emechara ya ma mebie ya. Ntụ ntụ metallurgy, nke bụ subset nkentụ ntụ metal sintering, metụtara mmepụta nke ceramik. N'ihi ya, a nwekwara ike iji ọtụtụ ọkụ na-emepụta ihe na-emepụta ihe maka metal powdered iji mepụta ihe seramiiki.

1. Nkwadebe nke ntụ ntụ ntụ. Enwere ike kewaa ụzọ igwe igwe dị ugbu a ụzọ abụọ: usoro igwe na usoro physicochemical. Enwere ike kewaa usoro igwe n'ime: nchicha igwe na atomization; A na-ekewa ụzọ anụ ahụ na nke kemịkalụ n'ime usoro corrosion electrochemical, usoro mbelata, usoro kemịkalụ, usoro mbelata-kemịkalụ, usoro ntinye mmiri, usoro ntinye mmiri mmiri na usoro electrolysis. N'ime ha, a na-ejikarị usoro mbelata, usoro atomization na usoro electrolysis.

2. A na-eme ntụ ntụ ka ọ bụrụ oghere na ọdịdị a chọrọ. Ebumnuche nke ịkpụzi bụ inye oghere ahụ ọdịdị na nha, na inye ya njupụta na ike. A na-ekewa usoro nhazi n'ime nrụgide na-akpụ na enweghị nrụgide. A na-eji ịkpụzi nrụgide eme ihe n'ọtụtụ ebe na ịkpụzi nrụgide.

3. billet sintering. Nzọụkwụ dị mkpa nantụ ntụ metallurgy sinteringTeknụzụ ọkụ na-ekpo ọkụ. Enwere ike ịgbanye billet raw ahụ mgbe emechara ya iji nye ya njiri arụ ọrụ na nke anụ ahụ achọrọ. Nwepu otu na ọtụtụ sistemu sistemu bụ akụkụ abụọ nke sintering. The sintering okpomọkụ dị ala karịa agbaze ebe nke metal na alloy tinye n'ọrụ maka siri ike steeti sintering nke unit usoro na multi-element usoro. Okpomọkụ nke na-agbaze maka usoro mmiri mmiri nke sistemu ihe mejupụtara ọtụtụ na-adịkarị elu karịa ebe mgbaze nke akụrụngwa fusible mana ọ dị ala karịa ebe mgbaze nke akụrụngwa refractory. Enwere usoro ịgbanye ihe pụrụ iche dị ka ịgba égbè na-adịghị mma, ịgbaze agbaze, na ịpị ọkụ na mgbakwunye na sntering ọkọlọtọ.
4. na-agbaso ọgwụgwọ ngwaahịa. Na-esote sintering, enwere ike iji usoro nhazi dị iche iche dabere na ihe achọrọ nke ngwaahịa ikpeazụ. dị ka machining, okpomọkụ ọgwụgwọ, electroplating, finishing, na ndị ọzọ. Na mgbakwunye, n'afọ ndị na-adịbeghị anya, a na-eji ntụgharị, akpụ akpụ, na ụzọ ndị ọzọ na-emepụta ihe na-emepụta ihe ndị a na-emepụta ntụ ntụ, na-enwetakwa nsonaazụ kacha mma.
