Iyini insimbi eyimpuphu

Okuthathwayo Okubalulekile

• Insimbi eyimpushana ikhiqizwa ngamasu athuthukile afana ne-atomization, ukunciphisa, kanye ne-alloying yemishini, okuvumela izakhiwo ezihambisanayo kanye nokusetshenziswa.
• Ukwenziwa kwensimbi ewumpushana kusebenza kahle kakhulu, kunciphisa imfucuza futhi kunciphisa izindleko zokukhiqiza kuze kufike ku-70%, okwenzaukukhetha okungabiziezimbonini.
• I-Powdered metal's versatility ivumela ukusetshenziswa kwayo kuimikhakha eyahlukene, okuhlanganisa izimoto, i-aerospace, nokunakekelwa kwezempilo, lapho ihlinzeka ngezinto ezihlala isikhathi eside, ezingasindi, nezinembayo.

Yenziwa kanjani insimbi eyimpushana?

Ukukhiqizwa kwensimbi eyimpuphukuhilela amasu amaningana athuthukile enzelwe ukufeza izakhiwo ezithile kanye nezicelo. Ake sihlole izindlela ezibalulekile ezisetshenziswa kule nqubo.

I-Atomization

I-Atomization ingenye yezindlela ezivame kakhulu zokukhiqiza insimbi eyimpuphu. Iqala ngokuncibilika kwensimbi encibilikisiwe, ebese ithululwa ngamajethi egesi noma amanzi. Lesi senzo sihlukanisa insimbi encibilikisiwe ibe amaconsi amancane aqina ngaphambi kokuthi ahlangane.

Kunezindlela ezimbili eziyinhloko ze-atomization: igesi kanye ne-atomization yamanzi. I-atomization yegesi ivumela insimbi encibilikisiwe ukuthi ihlale isesimweni soketshezi isikhathi eside, okuvumela ukwakheka kwezinhlayiya eziyindilinga. Le ndlela ikhiqiza izimpushana ezinokugeleza okungcono kanye nokuminyana okuphezulu. Ngakolunye uhlangothi, i-atomization yamanzi ipholisa ngokushesha amaconsi, okuholela ezinhlayiyeni ezimise ngendlela engavamile ngenxa yenqubo yokuqiniswa okusheshayo. Indlela ngayinye inikeza izinzuzo eziyingqayizivele kuye ngokuthi izakhiwo ezifunwayo zensimbi eyimpuphu.

Ukunciphisa kanye ne-Electrolysis

Ukunciphisa kuhilela ukusabela kwamakhemikhali okukhipha insimbi ensimbi yayo. Insimbi iyachotshozwa, ihlanganiswe nekhabhoni, bese ishiswa esithandweni. Le nqubo inciphisa amazinga omoya-mpilo kanye ne-carbon, ishiya insimbi efana nesipontshi. Ukunciphisa isimo esiqinile kulandela indlela efanayo, lapho ingxube ye-ore-carbon idlula esithandweni, ikhiqize insimbi yesipontshi enokungcola okunciphile.

I-Electrolysis ingenye indlela eqinisekisa ukuhlanzeka okuphezulu. Ngokusebenzisa amasu e-electrodeposition alawulwayo, le nqubo idala izimpushana zensimbi ezisebenziseka kalula futhi ezilungele izinhlelo zokusebenza ezidinga ubumsulwa obukhethekile.

I-Mechanical Alloying

Ingxubevange yemishini ihlanganisa izinsimbi ezihlukene zibe impushana eyodwa. Le nqubo isebenzisa izigayo zamabhola ezinamandla aphezulu ukuze ziphuke ngokuphindaphindiwe futhi zishise izinhlayiya zensimbi ndawonye. Ngokuhamba kwesikhathi, izinsimbi zihlangana ezingeni elincanyana, zenze ingxubevange efanayo. Le ndlela iwusizo ikakhulukazi ekudaleni izinto eziyinhlanganisela yamandla athuthukisiwe nokuqina.

Sintering kanye Additive Manufacturing

I-Sintering idlala indima ebalulekile ekubumbeni nasekuqiniseniimikhiqizo yensimbi eyimpuphu. Phakathi nale nqubo, i-compact eluhlaza (ifomu le-powder elicindezelwe) liyashiswa ukuze libophe izinhlayiya. Lesi sinyathelo sisusa izinto zokugcoba, sikhuphule ukuminyana, futhi sithuthukise izakhiwo zemishini njengamandla nokuqina. Njengoba ubukhulu bezimbotshana buncipha, okokusebenza kufinyelela ukuminyana okufunayo kanye ne-conductivity.

Ukukhiqiza okungeziwe, nomaUkuphrinta kwe-3D, isebenzisa insimbi eyimpuphu ukuze kwakheke umumo oyinkimbinkimbi ungqimba ngongqimba. Le ndlela yokusungula ivumela ukwenza ngokwezifiso okunembayo futhi inciphise udoti wezinto ezibonakalayo, ikwenze kube ukukhetha okudumile ezimbonini ezifana ne-aerospace nokunakekelwa kwezempilo.

Ukukhiqizwa kwensimbi eyimpuphu kuhlanganisa isayensi nobunjiniyela ukuletha izinto ezihlukahlukene zokukhiqiza zesimanje. Ukuqonda lezi zinqubo kugqamisa ubuhlakani obusemuva kwensimbi eyimpuphu namandla ayo okuguqula.
