Umgubo wesinyithi vs ukuphosa

1. Imathiriyeli ekrwada

Iyaphosa-Izinto zokuphosa zihlala zizixhobo ezingenayo i-ferrous, njengei-aluminium, i-magnesium, i-zinc, ezineendawo zokunyibilika ezisezantsi. Ubume bemveliso yokuphosa ingaba yipleyiti, ibhanti, intonga, njl.;

I-metallurgy yomgubo– Isinyithi okanye umgubo wentsimbi (okanye umxube wentsimbi kunye nomgubo ongeyontsimbi) njengezinto ezikrwada. Nangona kukho umgangathoizixhobo zentsimbi yomgubo, kunokwenzeka kwakhona ukuxuba umgubo. Oku kuvumela ukudalwa kweempawu ezithile, ezifana neempawu eziphezulu zemagneti zamalungu emoto, ezifuna indawo ephezulu yokunyibilika umgubo wentsimbi. I-Metallurgy yomgubo idla ngokuba nezi zinto zilandelayo:intsimbi, intsimbi, nickel, titanium, ubhedu, isilicon, phosphorus.

IZIQULATHO EZINGXENYE ZOPHUWU

2. Inkqubo

Iyaphosa- kukusetyenziswa kwezinto ezisuka kulwelo ukuya kwisigaba esiqinileyo sokubumba inguqu, isinyithi sinyibilika ngokupheleleyo, imveliso yokugqibela iyatshintsha.

Umgubo weMetallurgy- iteknoloji yenkqubo yokwenza isinyithi okanye umgubo wesinyithi (okanye umxube wesinyithi kunye nomgubo ongeyiyo-metal) njengezinto eziluhlaza, ukubunjwa kunye ne-sintering, ukuvelisa izinto zetsimbi, i-composites kunye neentlobo ezahlukeneyo zeemveliso.

3. Unyango lobushushu

Iyaphosa– Ngokwezinto ezahlukeneyo kunye neemfuno zokusebenza zinokuba neenkqubo ezahlukeneyo zokunyanga ukushisa, ezifana ne-aluminium alloy annealing, ukucima, unyango lwesisombululo, ukomeleza ukuguga;

I-metallurgy yomgubo– powder metallurgy indlela yesiqhelo, izinto ayikwazi ukuba xinene ngokupheleleyo, ngokungenakuthintelwa ukuvelisa ezinye izikhewu, iya kunciphisa amandla ayo, ngokweemfuno ezahlukeneyo izinto eziphathekayo, ukugqiba ukuba unyango ubushushu emva sintering, ngokubanzi ngokusebenzisa ukucima kunye nokuqukumbela kunokuphucula ukusebenza kwezinto.

 4. Ulawulo lombutho

Iyaphosa– Kuukuphosa ukufa, ukulawulwa kwe-microstructure kunqunywe ngumlinganiselo wokupholisa, oxhomekeke kwizinto ezifana nommandla kunye nomthamo, kunye nombutho wokuphosa ngokuqhelekileyo uxinene.

I-metallurgy yomgubo- I-powder ngenxa yokuba izinto eziluhlaza zincinci, ngokulawulwa kwenkqubo, zinokufumana ingqolowa efanayo, i-microstructure emihle, igweme ngokupheleleyo ukubunjwa kunye nokuhlukaniswa kwe-microstructure eyenziwe ngokuphosa. Umjikelo ngamnye ubeka ubunzima obufanayo bepowder kwi-mold kwaye uyihlanganise kwi-density efanayo. Iimathiriyeli zesinyithi somgubo zishushu ngokucinezela i-isostatic, kwaye ubuninzi bezinto eziqhelekileyo ze-sintered abukho kakuhle njengokuphosa.

5. Iimpawu zoomatshini

Xa kuthelekiswa nezinye iinkqubo,ukuphosa ukufainikeza ubuchule bokubumba obuhle kakhulu. Nangona kunjalo, sinokusebenzisa phantse amathuba afanayo okuyilwa njengemveliso yesinyithi somgubo ukunika iimveliso iipropathi ezingcono zoomatshini.

Izixhobo zokufa azikho magnetic. Ngaphandle kokuba zibekwe ngaphakathi kwelinye icandelo elenziwe ngenye isinyithi, akukho kufaneleka kwemagnethi. I-metallurgy yomgubo inezixhobo ezahlukeneyo zemagnethi ezikhoyo. Enye ingxaki nge-die casting kukuba imveliso ibuthathaka kwaye yaphuka ngokulula. Izinto eziphambili ze-die-cast parts ziyi-zinc kunye ne-aluminiyam, izinto ezithambileyo zetsimbi.Amalungu e-metallurgy yomgubo, ngokuqhelekileyo yenziwe ngentsimbi, inobunzima obuphezulu. Ukusebenzisa izixhobo ezomeleleyo kunokufikelela kwimilo efanayo ngezinto ezincinci, ezinokugcina indawo yoyilo lweemoto kunye nobunzima.

6. Iindleko

Uyilo lwamacandelo ngowona mqhubi weendleko, nangona uyilo lunokwenziwa ngokwezifiso ukuze luhambelane nenkqubo yokubumba. Nangona kunjalo, kukho iyantlukwano phakathi kweemveliso zesinyithi somgubo kunye nokuphosa ukufa, kwaye lo mahluko zikwangowona nobangela uphambili ochaphazela iindleko.

Ukusetyenziswa kwezinto eziphathekayo/isivuno. Iimveliso ze-metallurgy ze-powder zinezinga eliphantsi le-scrap, eliyinzuzo enkulu ekusebenziseni izinto eziphezulu zexabiso ezifana nobhedu kunye nensimbi engenasici.

Uqhubekeko lwesibini. Iinxalenye zeDie cast kufuneka zichetywe ukuze kususwe imiphetho ekrwada, zenziwe ngokutsha kwaye ziphathwe ubushushu; Uninzi lwamalungu e-metallurgy ayifuni ukusetyenzwa okwesibini.

Ukusetyenziswa kwempahla ekrwada. Ukunyibilika kwesinyithi kufuna amandla, ngakumbi kwimathiriyeli enamanqaku aphezulu okunyibilika. Nangona i-sintering inamandla amakhulu, ukusetyenziswa kukonke kwe-sintering kunokuba ngaphantsi koko kuphosa.
