Izinhlobo Ze-3D Zokuphrinta Zensimbi Nezinhlelo Zazo Eziyinhloko

Njengamanje, kunezinto eziningi ze-metal powder ezingasetshenziselwa ukuphrinta kwe-3D.Ngenxa ye-spheroidization esobala kanye ne-agglomeration ye-single-component metal powder ngesikhathi sokwakhiwa, kulula ukubangela ukubola kwe-sintering kanye nokuminyana okuxekethile.Ngakho-ke, i-multi-component metal powder noma i-pre-alloyed powder iyimpahla evamile eluhlaza ye-3D metal printing powder.

Ngokusho kwezakhi eziyinhloko ze-matrix, lezi zimpushana zensimbi zingaba izinto ezisekelwe ensimbi, ama-alloys asekelwe ku-nickel, i-titanium ne-titanium alloys, ama-cobalt-chromium alloys, ama-aluminium alloys, ama-alloys ethusi, njalonjalo.Izinsimbi ezihlukene zinezakhiwo ezahlukene, ngakho-ke kukhona umehluko ekusetshenzisweni.Ake sibheke izici zabo nezindawo zokusebenzisa.

1. I-Titanium-based alloy powder
Ingxubevange esekwe ku-Titanium ingenye yezinsimbi ezine-biocompatibility ehamba phambili eyaziwa njengamanje, futhi inezakhiwo ze-osseointegration kanye ne-Young's modulus eseduze nethambo lomuntu, ngakho ithathwa njengezinto ezingcono kakhulu ze-biomedical zensimbi namuhla.Isetshenziswa ngokomtholampilo ekufakweni kwezicubu eziqinile zomuntu kanye nokulungisa amanxeba, nasekuhlinzweni kwenhliziyo, njengama-stents enhliziyo namagobolondo e-pacemaker.Ukukhishwa kwesivinini esikhulu kanye nokunemba okuphezulu kuhlangabezana kakhulu nezidingo zohlelo lokusebenza lwemboni yezokwelapha.
Yiqiniso, ngaphezu kwezokwelapha, lokhu kubuye kusetshenziswe kabanzi emikhakheni efana ne-aerospace, izimboni zezimoto nezobunjiniyela ezidinga ukunciphisa isisindo esibalulekile ngenkathi kugcinwa ukusebenza okuphezulu.

2. I-aluminium alloy powder
I-aluminium alloy isetshenziswa kabanzi embonini namuhla, ikakhulukazi ngenxa yezakhiwo zayo ezingasindi: ingxenye ye-aluminium iyingxenye eyodwa kwezintathu kuphela yensimbi.Idlala indima ebalulekile ku-lightweight yamathuluzi okuthutha.I-aluminium powder ifaneleka ngokukhethekile izinhlelo zokusebenza ezingasindi ezinezindonga ezincane kanye nobujamo bejometri obuyinkimbinkimbi.Isetshenziswe kabanzi kwezokundiza, izimoto, ukukhiqiza imishini, nezimboni zokwakha imikhumbi.

3. I-Copper ne-copper alloy powder
Ngokuhamba kahle kwe-thermal kanye ne-conductivity kagesi, amandla amahle wemishini nokumelana nokugqoka, yinto ekhethwayo yezingxenye zokushintshanisa ukushisa.Imvula eyenza lukhuni ingxubevange yethusi i-CuCr1zr (ithusi le-chromium zirconium), igcina izakhiwo ezinhle kakhulu zomshini kanye ne-ductility enhle ebangeni lokushisa elingu-300-500 °C ngemva kokwelashwa kokushisa.

4. I-iron-based alloy powder
Ukutholakala okuhle nokusebenza kahle kwensimbi kwenza insimbi ibe ihhashi langempela lomsebenzi ezimbonini eziningi.Ukuhlanganisa isisekelo sensimbi nezinto ezihlukene ze-alloying kwenza kube nokwenzeka ukudala izinhlobonhlobo zezinsimbi ezinezakhiwo ezahlukene.Insimbi engagqwali inezakhiwo ezinhle zomshini kanye nokumelana nokugqwala okuhle kakhulu, ngakho-ke izinto zensimbi engagqwali zingabonakala endizeni, ezimotweni, ezokwelapha, zamakhemikhali, ezikhunjini, njll.

5. I-powder superalloy esekelwe ku-nickel
Ukumelana ne-oxidation nokumelana nokugqwala kwe-nickel alloy kuyenza ifanele indawo enzima yokushisa okuphezulu nokucindezela okuphezulu.Lapho ingxubevange ye-nickel ifudunyezwa, ungqimba lwe-oxide olujiyile futhi oluzinzile luzodlula ebusweni bengxubevange ukuze kuvikelwe ingaphakathi lengxubevange ekugqwaleni.Ama-Nickel alloys agcina izakhiwo ezinhle zemishini phezu kwebanga lokushisa elibanzi.
Izakhiwo eziyinhloko zaleli klasi lezinsimbi yizinga lokushisa eliphezulu lokugqwala kanye nokumelana ne-oxidation, ezifanele ama-jet turbines, ama-gas turbines, uwoyela negesi, imikhumbi yokucindezela noma izingxenye ezicutshungulwe ngamakhemikhali.

6. I-cobalt alloy powder
Ngenxa yokumelana nokugqwala okuhle kakhulu nokumelana nokugqwala, ingxubevange esekwe ku-cobalt ifanele ukufakelwa isikhathi eside ngomthwalo onzima wangaphakathi, ukumelana nokugqoka kanye nezidingo eziphakeme zokumelana nokugqwala, njengamalunga ahlukahlukene okwenziwa kanye nokufakelwa kokuhlinzwa kwepulasitiki, futhi inezinhlelo zokusebenza umkhakha wodokotela bamazinyo.
