Ukhetho phakathiumgubo wesinyithi kwayeukuphosa ukufangokuqhelekileyo ngumba wenxalenye yobungakanani okanye iimfuno zezinto eziphathekayo. Ngokuqhelekileyo zisetyenziswa izinto zokulahla i-aluminiyam, i-alloys ye-magnesium kunye ne-alloys ye-zinc, kunye ne-alloy ye-alloy die castings nayo ingasetyenziswa.Njengomzi-mveliso wesinyithi omnye wokumisa umveliso wesinyithi kunye nomvelisi we-aluminium die e-China, siya kukhetha eyona nkqubo ilungileyo kuwe!

Xa kuthelekiswa neendawo ze-metallurgy ze powder kunyeiindawo zokubumba inaliti yesinyithi, ubungakanani beemveliso zokufa bukhulu kakhulu. Xa ezi mfuno zilandelayo zifunwa, inkqubo ye-metallurgy yomgubo ifanelekile ngakumbi:

1. Amandla aphezulu kakhulu, ukomelela kokuqina kwezinye iialloyi ezine-iron-based sintered angaphezulu ngokuphindwe kathathu kunowona mandla aphakamileyo ealloyi zokugalela ukufa.
2. Ukumelana nokunxiba okuphezulu kunye nokusebenza okuphezulu kwe-antifriction, enokuthi isonjululwe nge-iron-based and copper-based sintered alloys efakwe ngeoli yokuthambisa.
3. Ukushisa okuphezulu kokusebenza, okungasombululwa nge-iron-based and copper-based alloys sintered.
4. I-corrosion-resistant, i-alloy-based sintered alloy kunye ne-sintered steel stainless steel inokuhlangabezana neemfuno.

Phakathi komgubo wesinyithi kunye ne-die-casting, i-zinc die-casting inokuthi ithathe indawo ye-iron-based.iimveliso zomgubo wesinyithiphantsi kwemeko yokusebenzisa ubushushu obungekho ngaphezulu kwama-65 degrees Celsius kunye namandla aphakathi. Kodwa ngokuqhelekileyo i-metallurgy engumgubo ithandeka ngakumbi.

Iindidi zamalungu e-powder metallurgy

1. Amalungu esakhiwo

Iigiya kunye neendawo ezahlukeneyo zokuthwala amandla ezenziwe ngobhedu, intsimbi, ialloys zethusi, iialloys zealuminium, njl.

I-Sintered metal-impregnated bearings. I-iron-based based and copper-based porous bearings ene-porosity ye-15% ukuya kwi-25% izaliswe ngeoli yokuthambisa.

Iibheringi ze-alloy ze-copper-backed sintered. Umaleko wokuqala yintsimbi ngasemva kwaye umaleko wesibini yi-sintered copper-aluminium alloy.

DU, DX iibheringi, njl.

Usetyenziso lwezixhobo zolwakhiwo: iimoto, izixhobo zoomatshini, oomatshini bezolimo, oomatshini belaphu, izixhobo, oomatshini bokuthunga, izixhobo zombane, njl. njl.

2. Amalungu efriction

Iidiski ze-clutch okanye i-brake bands njl. ezenziwe ngentsimbi exhasa ngentsimbi okanye ubhedu olusekelwe kwimiqulu yomgubo

Ukusetyenziswa kwamalungu okungqubana: amacandelo okungqubana kwiimoto, iinqwelomoya, amatanki, oomatshini bokwakha, izixhobo zoomatshini kunye noomatshini bamandla.

3. Izinto zokucoca kunye nezinye izinto ezixubileyo

into yokucoca. Iimveliso ezimile okwekomityi, ezimile okwekhowuni, isilinda kunye nentonga eyenziwe ngobhedu olungqukuva, i-nickel, intsimbi, intsimbi engatyiwa, kunye nezinye iipores zentsimbi ezinemibhobho efanayo.

Izinto ezicinyiweyo. Kukho iintonga, imichilo kunye neetyhubhu ezenziwe nge-nickel, i-nichrome, insimbi engenasici kunye nezinye izinto ezichasene ne-corrosion kunye ne-porosity ukuya kwi-50%.

Iimveliso zetsimbi zeFiber. I-porosity ephezulu (ukuya kuma-80%) amanqaku enziwe kwimicu yentsimbi.

Ukusetyenziswa kwezinto zokucoca kunye nezinye izinto ezinobungozi: ezisetyenziselwa ukuhluza iigesi ezahlukeneyo kunye nolwelo kwishishini lemichiza, izixhobo zoomatshini, iinqwelomoya, iimoto, iinjini zokutsha zangaphakathi, njl.
