2, Isimiso se-vacuum metal powder atomization

I-atomization ye-vacuum powder iyinqubo ye-atomization ye-metal powder eyenziwa endaweni ye-vacuum. Umgomo oyinhloko uwukusebenzisa ukugeleza komoya okunesivinini esikhulu, amanzi anomfutho ophezulu, noma amandla aphakathi nendawo ukuze kuhlakazwe insimbi encibilikisiwe ibe amaconsi amancane ngaphansi kwezimo ze-vacuum. Ngenxa yobukhona bendawo ye-vacuum, ukuthintana phakathi kwamaconsi ensimbi nomoya kungancishiswa ngokuphumelelayo, kugwenywe i-oxidation nokungcola, ngaleyo ndlela kuthuthukiswe izinga le-metal powder.

Enqubweni ye-vacuum metal powder atomization, impahla eluhlaza yensimbi iqala ukushiselwa ibe yisimo esincibilikisiwe. Bese, ngombobo othize we-atomizing, insimbi encibilikisiwe ifafazwa ngesivinini esikhulu futhi ihlanganyele ne-atomizing medium (njengegesi engasebenzi, amanzi anomfutho ophezulu, njll.) ukuze kwakheke amaconsi amancane. Lawa maconsi aphola ngokushesha futhi aqine endaweni engenalutho, agcine enza impushana yensimbi.

3, Indlela ye-vacuum metal powder atomization

(1) I-Vacuum Inert Gas Atomization Method

Isimiso: Insimbi encibilikisiwe ifuthwa ngombhobho endaweni ye-vacuum, futhi igesi engasebenzi (njenge-argon, i-nitrogen, njll.) isetshenziselwa ukuba nomthelela ekugelezeni kwensimbi, iyihlakaze ibe amaconsi amancane. Amagesi angenayo adlala indima ekupholiseni nasekuvikeleni amaconsi ensimbi phakathi nenqubo ye-atomization, ukuvimbela i-oxidation nokungcola.

Izici: Ukuhlanzeka okuphezulu nezimpushana zensimbi eziyindilinga zingalungiswa, zilungele izinkambu ezidinga ikhwalithi yempushana ephezulu, njenge-aerospace, electronics, njll.

(2) Indlela ye-vacuum atomization

Isimiso: Insimbi encibilikisiwe ifuthwa ngombhobho endaweni ye-vacuum, futhi ukugeleza kwamanzi anesivinini esikhulu kuthinta ukugeleza koketshezi lwensimbi, luhlakaze lube amaconsi amancane. Amanzi adlala indima ekupholiseni nasekuphuleni ukugeleza koketshezi lwensimbi phakathi nenqubo yokwenza i-athomu.

Izici: Ingalungisa izimpushana zensimbi ezinosayizi wezinhlayiyana ezicolekile kanye nezindleko eziphansi, kodwa izinga le-oxidation lempushana liphakeme ngokuqhathaniswa futhi lidinga ukucutshungulwa okulandelayo.

(3) Indlela ye-atomization ye-vacuum centrifugal

Isimiso: Jova insimbi encibilikisiwe kudiski ezungezayo eyi-centrifugal noma i-crucible, futhi ngaphansi kwesenzo samandla aphakathi nendawo, insimbi encibilikisiwe iphonswa ngaphandle futhi ihlakazwe ibe amaconsi amancane. Amaconsi ayapholisa futhi aqine endaweni ye-vacuum, enze impushana yensimbi.

Izici: Ingakwazi ukulungisa izimpushana zensimbi ezine-sphericity ephezulu kanye nokusabalalisa usayizi wezinhlayiyana ezifanayo, ezifanele ukulungiselela izinto ezisezingeni eliphezulu ze-metal powder.

4. Izici ze-Vacuum Metal Powder Atomization

①Ukuhlanzeka okuphezulu

Imvelo ye-vacuum inganciphisa ngempumelelo ukuxhumana phakathi kwe-powder yensimbi nomoya, igweme i-oxidation nokungcola, futhi ngaleyo ndlela ithuthukise ukuhlanzeka kwempushana.

Kwezinye izinto zensimbi ezinezidingo zokuhlanzeka okuphezulu, njengama-alloys e-titanium, ama-alloys ashisa kakhulu, njll., ubuchwepheshe be-vacuum metal powder atomization buyindlela efanelekile yokulungiselela.

②I-sphericity enhle

Ngesikhathi senqubo ye-vacuum metal powder atomization, amaconsi avame ukwenza izimo eziyindilinga ngaphansi kwesenzo sokungezwani kwendawo, okuholela ekuyindilinga okuhle kwempushana yensimbi elungisiwe.

Izimpushana eziyindilinga zinokugeleza okuhle, ikhono lokugcwalisa, nokucindezelwa, okuzuzisa ukuthuthukisa ikhwalithi nokusebenza kwemikhiqizo ye-powder metallurgy.
