Iindaba

Imfuno yomgubo wentsimbi iye yanda kule minyaka yakutsha nje, iqhutywa yinkqubela phambili kwimveliso eyongeziweyo, i-aerospace, izithuthi kunye namanye amashishini. Umgubo wesinyithi uyimfuneko kwiinkqubo ezinje ngoshicilelo lwe-3D, i-sintering kunye nomgubo wesinyithi. Enye yeendlela ezisebenzayo zokuvelisa ezi powders kukusebenzisa i-metal powder atomization, inkqubo eguqula isinyithi esinyibilikisiweyo sibe ngamasuntswana amahle. Eli nqaku liphonononga indlela isinyithi eguqulwa ngayo ibe ngumgubo, igxininise indima yezixhobo ze-atomization yomgubo kule nkqubo ebalulekileyo yokuvelisa.

Qonda i-metal powder atomization

I-Metal powder atomization yinkqubo eguqula isinyithi esinyibilikisiweyo sibe ngamasuntswana omgubo ocolekileyo. Itekhnoloji ithandwa ngokukwazi ukuvelisa iipowders ezinobungakanani besuntswana elifanayo, imilo kunye nokusabalalisa, okubaluleke kakhulu kwiinkqubo ezahlukeneyo. Inkqubo ye-atomization inokwahlulwa ngokufanelekileyo kwiindidi ezimbini eziphambili: i-atomization yegesi kunye ne-atomization yamanzi.

Igesi atomization

Kwi-atomization yegesi, isinyithi esityhidiweyo sigalelwa nge-nozzle kwaye i-atomized yi-high-velocity gas stream, ngokuqhelekileyo i-nitrogen okanye i-argon. Ukupholisa ngokukhawuleza kwamaconsi atyhidiweyo kubangela ukubunjwa kweengqungquthela zetsimbi eziqinileyo. Le ndlela isebenzayo ngokukodwa ekuveliseni i-powders ephezulu ngenxa yokuba igesi engasebenziyo inciphisa i-oxidation kunye nokungcoliswa.

I-atomization yamanzi

Iatomization yamanzi, kwelinye icala, isebenzisa iijethi zamanzi ezinoxinzelelo oluphezulu ukuqhekeza isinyithi esinyibilikisiweyo sibe ngamathontsi. Le ndlela idla ngokungabizi kakhulu kwaye inokuvelisa izixa ezikhulu zomgubo. Nangona kunjalo, kunokubangela i-oxidation ethile, enokuchaphazela ukusebenza kwemveliso yokugqibela. I-atomization yamanzi isoloko isetyenziselwa ukuvelisa umgubo wentsimbi, ngelixa i-atomization yegesi ikhethwa kwiintsimbi ezingezizo i-ferrous kunye ne-alloys.

Inkqubo ye-Metal powder atomization

Inkqubo yokuguqula isinyithi ibe ngumgubo ngokusebenzisa i-atomization ibandakanya amanyathelo abalulekileyo:

Ukunyibilikisa iMetal: Isinyathelo sokuqala kukunyibilikisa isinyithi okanye i-alloy kwisithando somlilo. Oku kunokwenziwa ngokusebenzisa iindlela ezahlukeneyo, kubandakanywa ukunyibilika kwe-induction, ukunyibilika kwe-arc okanye ukunyibilika kokumelana. Ukukhethwa kwendlela yokunyibilika kuxhomekeke kuhlobo lwetsimbi kunye neempawu ezifunwayo zomgubo wokugqibela.

Atomization: Emva kokuba isinyithi sincibilikile, sidluliselwa kwigumbi le-atomization. Kulo gumbi, isinyithi esityhidiweyo sixhomekeke kwi-high-pressure gas okanye iijethi zamanzi, ziwaphule zibe ngamaconsi amancinci. Ubungakanani bamaconsi bunokulawulwa ngokulungelelanisa uxinzelelo kunye nesantya sokuhamba kwe-atomized medium.

Ukupholisa kunye nokuqinisa: Amathontsi aphole kwaye aqina ngokukhawuleza njengoko edlula kwigumbi lokutshiza. Izinga lokupholisa libalulekile njengoko lichaphazela i-microstructure kunye neempawu zepowder ephumela. Amazinga okupholisa ngokukhawuleza ngokubanzi avelisa amasuntswana acolekileyo kunye ne-microstructure efanayo.

Ukuqokelelwa kunye noHlelo: Emva kokuqina, i-powder yensimbi iqokelelwa kwaye ihlelwe ngokwesayizi ye-particle. Oku kuqhele ukwenziwa kusetyenziswa iindlela zokuhlola okanye zokuhlela umoya. Imveliso yokugqibela inokuthi iqhubele phambili ukuqhubela phambili, njengokugaya okanye ukudibanisa, ukufumana ukusabalalisa ubungakanani obufunwayo kunye neempawu.

Emva kokulungiswa: Ngokuxhomekeke kwisicelo, i-powders yensimbi inokufuna ukuqhutyelwa phambili, njengokutyabeka komhlaba okanye unyango lobushushu, ukunyusa iimpawu zabo. Eli nyathelo libalulekile ukuqinisekisa ukuba umgubo uhlangabezana neemfuno ezithile zesicelo esijoliswe kuyo.
