Uru nke ntụ ntụ metallurgy usoro

1, ọnụ ọgụgụ ka ukwuu nke refractory ọla na ogige ha, ụgha alloys, porous ihe nwere ike arụpụtara naanị site ntụ metallurgy usoro.

2, n'ihi na powder metallurgy usoro nwere ike pịa n'ime ikpeazụ size nke compaction, na-enweghị ma ọ bụ obere mkpa maka ụdi nhazi nhazi, ọ nwere ike dị ukwuu ịzọpụta metal, belata ngwaahịa cost.The ọnwụ nke metal na mmepụta nke ngwaahịa site ntụ ntụ metallurgy. Usoro bụ naanị 1-5%, ebe mfu nke ígwè na mmepụta nke ngwaahịa site na nkedo nkịtị nwere ike ịdị elu dị ka 80%.

3, n'ihi na usoro metallurgy ntụ ntụ na usoro mmepụta ihe anaghị agbaze ihe ahụ, ọ naghị atụ egwu ịgwakọta na adịghị ọcha nke crucible na deoxidizer na-ebute, na sintering na-emekarị na-arụ ọrụ na agụụ na ibelata ikuku, ọ bụghị egwu oxidation. , ma ghara inye ihe ọ bụla mmetọ ihe, ọ ga-ekwe omume ịme ihe dị elu dị ọcha.

4, ntụ ntụ metallurgy usoro nwere ike hụ na correctness na uniformity nke ihe mejupụtara ratio.5, ntụ ntụ metallurgy kwesịrị ekwesị maka mmepụta nke otu udi na a ọnụ ọgụgụ buru ibu nke ngwaahịa, karịsịa gia na ndị ọzọ na elu nhazi ụgwọ nke ngwaahịa, na ntụ ntụ metallurgy. nrụpụta nwere ike belata ọnụ ahịa mmepụta nke ukwuu.

Isi usoro nke ntụ ntụ metallurgy usoro bụ

1, nkwadebe nke raw material powder.Existing pulverizing ụzọ nwere ike roughly kewara abụọ edemede: n'ibu na physico-chemical.The n'ibu usoro nwere ike kewara n'ime: n'ibu nzọpịa na atomization usoro;Physical na chemical ụzọ na-ọzọ kewara n'ime electrochemical corrosion. usoro, usoro mbelata, usoro kemịkalụ, ụzọ mbelata-kemịkalụ, usoro ntinye mmiri, usoro ntinye mmiri mmiri na usoro electrolysis. Ụzọ a na-ejikarị eme ihe bụ mbelata, atomization na electrolysis.

2. Ntụ ntụ na-akpụ a chọrọ udi nke oghere block.The nzube nke ịkpụzi bụ ime ka a ụfọdụ udi na size nke kọmpat, na-eme ka ọ nwere a ụfọdụ njupụta na ike.The ịkpụzi usoro bụ isi kewara n'ime nrụgide ịkpụzi na-abụghị. - ịkpụzi nrụgide. Nrụgide nrụgide bụ ịkpụzi a na-ejikarị eme ihe.

3. Sintering nke billet.Sintering bụ isi usoro na ntụ ntụ metallurgy.The ikpeazụ anụ ahụ na n'ibu Njirimara na-enwetara site sintering na compacted oghere mgbe akpụ. ebe agbaze nke ígwè na alloy na-eji maka usoro siri ike nke usoro unit na usoro ihe dị iche iche. ma elu karịa agbaze ebe nke fusible components.Na mgbakwunye na nkịtị sintering, e nwere rụrụ sintering, agbaze leaching usoro, na-ekpo ọkụ na ịpị usoro na ndị ọzọ pụrụ iche sintering Filiks.

4. Usoro nhazi usoro nke ngwaahịa. A pụrụ ịnakwere ọgwụgwọ ahụ mgbe sintering n'ụzọ dịgasị iche iche dị ka ihe dị iche iche chọrọ nke ngwaahịa ahụ dị ka ịmecha, immersion, machining, ọgwụgwọ okpomọkụ na electroplating.

Ihe na ngwaahịa metallurgy ntụ ntụ na ntụziaka mmepe n'ọdịnihu

1, nnọchiteanya nke ígwè dabeere alloy, ga-abụ nnukwu olu nke nkenke ngwaahịa, elu àgwà structural akụkụ mmepe.

2. Mepụta alloy arụmọrụ dị elu na microstructure edo edo, nhazi siri ike na njupụta zuru oke.

3. Alloys pụrụ iche, n'ozuzu nke mejupụtara usoro agwakọta, na-arụpụta site na nkwalite densification usoro.

4, na-emepụta ihe dị iche iche, amorphous, microcrystalline ma ọ bụ metastable alloy.

5, nhazi ụdị pụrụ iche na nke na-abụghị isi ma ọ bụ ihe mejupụtara akụkụ mejupụtara.

Mbụ, uru nke ntụ ntụ metallurgy usoro

1, nwere ike hazie ihe ndị pụrụ iche. Usoro ihe eji eme ntụ ntụ nwere ike ịmepụta ọla ndị na-emegharị emegharị yana ogige, pseudo alloys, na ihe porous.

2, chekwaa ígwè, belata ụgwọ ọrụ. N'ihi na enwere ike ịpịnye metallurgy ntụ ntụ n'ime njedebe ikpeazụ nke compaction, ọ dịghị mkpa iji nhazi nhazi. Ọnwụ nke ígwè a na-emepụta n'ụzọ dị otú a bụ nanị 1 ruo 5 pasent, ma e jiri ya tụnyere 80 percent maka nhazi nkịtị.

Mmepe nke ngwaahịa metallurgy ntụ ntụ

1, akụkụ nhazi dị elu: metallurgy ntụ ntụ bụ ihe nnọchianya nke alloy dabeere na ígwè, a ga-emepụta ya na nnukwu olu nke ngwaahịa ziri ezi, akụkụ nhazi dị elu.

2, elu arụmọrụ alloy: ntụ ntụ metallurgy n'ichepụta nwere edo microstructure Ọdịdị, nhazi siri ike na kpamkpam ok arụmọrụ alloy.

3, agwakọta na-adọ pụrụ iche alloy: ntụ ntụ metallurgy na enwekwukwa densification usoro rụpụta general pụrụ iche alloy nwere agwakọta na-adọ mejupụtara.

4, akụkụ ndị mejupụtara: nhazi ụdị pụrụ iche na nke na-abụghị isi ma ọ bụ ihe mejupụtara akụkụ mejupụtara.

5. Nkwadebe nke ihe dị ọcha dị elu. Usoro nhazi nke ntụ ntụ na usoro mmepụta ihe adịghị agbaze ihe ahụ, ọ gaghị ejikọta ya na ihe ndị ọzọ na-adịghị ọcha na-ebute, na sintering na-eme na oghere na ibelata ikuku, ọ dịghị atụ egwu oxidation na agaghị enwe mmetọ nke ihe onwunwe. Ya mere, ịdị ọcha nke ngwaahịa ahụ dị oke elu.

6, Nzizi nkesa nkesa ihe. Usoro metallurgy ntụ ntụ nwere ike hụ na nhazi na ịdị n'otu nke ihe mejupụtara ihe dị na nha.

7, mmepụta ihe dị ukwuu iji belata ụgwọ. Ntụ ntụ ntụ kwesịrị ekwesị maka mmepụta nke ngwaahịa na ọnụ ọgụgụ dị ukwuu nke edo edo, dị ka ngwá ọrụ na ngwaahịa ndị ọzọ na-eri nnukwu ọnụ ahịa, nke nwere ike ibelata mmepụta ihe.
