Ukukhetha phakathii-powder metallurgy futhiukufa kokusakazangokuvamile kuyindaba yosayizi wengxenye noma izidingo zezinto ezibonakalayo. Izinto ezisetshenziswayo ezisetshenziswa kakhulu yi-aluminium alloys, i-magnesium alloys nezinc alloys, kanye ne-copper alloy die castings nakho kungasetshenziswa.Njengefektri yensimbi ene-stop eyodwa yomkhiqizi we-powder metallurgy kanye nomkhiqizi we-aluminium die casting e-China, sizokukhethela inqubo engcono kakhulu!

Uma kuqhathaniswa nezingxenye ze-powder metallurgy kanyeizingxenye zokubumba umjovo wensimbi, usayizi wemikhiqizo ye-die casting mkhulu kakhulu. Lapho izidingo ezilandelayo zidingeka, inqubo ye-powder metallurgy ifaneleka kakhulu:

1. Amandla aphezulu kakhulu, amandla aqinile amanye ama-alloys asekelwe ku-iron aphakeme ngokuphindwe kathathu kunamandla aphakeme kakhulu ama-alloys okusansimbi.
2. Ukumelana nokugqoka okuphezulu nokusebenza okuphezulu kwe-antifriction, okungaxazululwa ngama-alloys asekelwe ensimbi kanye ne-copper afakwe ngamafutha okugcoba.
3. Ukushisa okuphezulu kokusebenza, okungaxazululwa ngama-alloys asekelwe ensimbi kanye ne-copper-based.
4. Ingxubevange engagqwali, esekwe ethusi nensimbi engagqwali e-sintered ingahlangabezana nezidingo.

Phakathi kwe-powder metallurgy kanye ne-die-casting, i-zinc die-casting ingase ithathe indawo ye-iron-based.imikhiqizo ye-powder metallurgyngaphansi kwesimo sokusebenzisa izinga lokushisa elingekho ngaphezulu kuka-65 degrees Celsius namandla aphakathi nendawo. Kodwa ngokuvamile i-powder metallurgy iyathandeka kakhulu.

Izinhlobo zezingxenye ze-powder metallurgy

1. Izingxenye zesakhiwo

Amagiya kanye nezingxenye ezihlukahlukene ezithwala amandla ezenziwe ngethusi, insimbi, ama-alloys ethusi, ama-alloys e-aluminium, njll.

Ama-bearings afakwe uwoyela wensimbi e-sintered. Izimbobo ezinezimbotshana ezisekelwe ku-iron kanye ne-copper ezine-porosity ye-15% kuya ku-25% zigcwele amafutha okugcoba.

Ama-alloy bearings ane-copper-backed sintered. Ungqimba lokuqala luyinsimbi emuva kanti ungqimba lwesibili luyingxube ye-copper-aluminium sintered.

I-DU, DX amabheringi, njll.

Izinhlelo zokusebenza zezingxenye zesakhiwo: izimoto, amathuluzi omshini, imishini yezolimo, imishini yendwangu, amathuluzi, imishini yokuthunga, amathuluzi kagesi, njll., izinjini ezivuthayo zangaphakathi, izimoto zikaloliwe, imishini yensimbi, iziqophamazwi, iziqophi zevidiyo, amamotho amancane, njll.

2. Izingxenye zokungqubuzana

Ama-clutch discs noma ama-brake band njll. enziwe ngensimbi esekelwa ngensimbi noma esekelwe ngethusi

Izinhlelo zokusebenza zezingxenye zokushayisana: izingxenye zokungqubuzana ezimotweni, indiza, amathangi, imishini yokwakha, amathuluzi omshini nemishini yamandla.

3. Izakhi zokuhlunga nezinye izinto ezimbotshana

isici sokuhlunga. Imikhiqizo emise okwenkomishi, emise okwekhoni, eyisilinda futhi emise okwenduku eyenziwe ngethusi eliyindilinga, i-nickel, insimbi, insimbi engagqwali, nezinye izimpushana zensimbi ezinezimbotshana ezifanayo.

Izinto ezicishiwe. Kunezinduku, imichilo namashubhu enziwe nge-nickel, i-nichrome, insimbi engagqwali nezinye izinto ezimelana nokugqwala ezine-porosity efinyelela ku-50%.

Imikhiqizo ye-fiber metal. I-porosity ephezulu (kufika ku-80%) izihloko ezenziwe ngemicu yensimbi emihle.

Ukusetshenziswa kwezakhi zokuhlunga nezinye izinto ezinama-porous: ezisetshenziselwa ukuhlunga amagesi ahlukahlukene noketshezi embonini yamakhemikhali, amathuluzi omshini, izindiza, izimoto, izinjini ezivuthayo zangaphakathi, njll., njengezihlungi zensimbi ezinama-porous ezingxenyeni zejethi, njengezingxenye zokucisha ezinezimbotshana endizeni, amaphaneli e-Acoustic, izakhi zokuhlunga ngezinjongo ezikhethekile.

Uyini umehluko phakathi kwe-powder metallurgy kanye ne-die casting? Ukuze uthole ulwazi olwengeziwe, sicela uthinte UJIEHUANG CHIYANG
