Iindaba

Imfuno yeempuphu zesinyithi inyukile kwiminyaka yakutshanje, iqhutywa kukuqhubela phambili kwimveliso eyongeziweyo, i-aerospace, iimoto kunye neminye imimandla eyahlukeneyo. Iimpuphu zesinyithi zibalulekile kwiinkqubo ezifana nokuprinta kwe-3D, ukucocwa kunye nokunyibilikiswa kwepowder metallurgy. Enye yezona ndlela zisebenzayo zokuvelisa ezi mpuphu kukusebenzisa i-metal powder atomization, inkqubo eguqula isinyithi esinyibilikisiweyo sibe ngamasuntswana amancinci. Eli nqaku liphonononga indlela isinyithi esiguqulwa ngayo sibe yimpuphu, sigxile kwindima yezixhobo ze-powder atomization kule nkqubo ibalulekileyo yokuvelisa.

Qonda i-atomization ye-metal powder

I-atomization ye-metal powder yinkqubo eguqula isinyithi esinyibilikisiweyo sibe ngamasuntswana e-fine powder. Le teknoloji ithandwa ngenxa yokukwazi kwayo ukuvelisa iipowders ezinobukhulu obufanayo be-particle, imilo kunye nokusasazwa, nto leyo ibalulekileyo kwiindlela ezahlukeneyo zokusetyenziswa. Inkqubo ye-atomization inokwahlulwahlulwa zibe ziintlobo ezimbini eziphambili: i-gas atomization kunye ne-water atomization.

Ukwenziwa kwe-atomization yegesi

Kwi-atomization yegesi, isinyithi esinyibilikisiweyo sithululwa nge-nozzle size sifakwe i-atomized yi-gas stream enesantya esiphezulu, ngokuqhelekileyo i-nitrogen okanye i-argon. Ukupholisa ngokukhawuleza kwamathontsi anyibilikisiweyo kubangela ukwakheka kwamasuntswana esinyithi aqinileyo. Le ndlela isebenza ngokukodwa ekuveliseni iipowders ezicocekileyo kakhulu kuba igesi engasebenziyo inciphisa i-oxidation kunye nongcoliseko.

Ukwenziwa kweatom yamanzi

Kwelinye icala, i-atomization yamanzi isebenzisa iijethi zamanzi ezinoxinzelelo oluphezulu ukuqhekeza isinyithi esinyibilikisiweyo sibe ngamathontsi. Le ndlela ngokubanzi ingabizi kakhulu kwaye inokuvelisa umgubo omninzi. Nangona kunjalo, inokubangela i-oxidation ethile, enokuchaphazela ukusebenza kwemveliso yokugqibela. I-atomization yamanzi idla ngokusetyenziswa ukuvelisa umgubo wesinyithi, ngelixa i-atomization yegesi ikhethwa kwiintsimbi ezingezizo iintsimbi kunye nee-alloys.

Inkqubo yokwenza i-atomization ye-metal powder

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

Ukunyibilikisa IsinyithiInyathelo lokuqala kukunyibilikisa isinyithi okanye i-alloy kwisithando somlilo. Oku kungenziwa kusetyenziswa iindlela ezahlukeneyo, kubandakanya ukunyibilikisa i-induction, ukunyibilikisa i-arc okanye ukunyibilikisa i-resistance. Ukukhetha indlela yokunyibilikisa kuxhomekeke kuhlobo lwesinyithi kunye neempawu ezifunwayo zomgubo wokugqibela.

Ukwenziwa kwe-atomization: Emva kokuba isinyithi sinyibilikisiwe, sidluliselwa kwigumbi le-atomization.

Ubungakanani bamathontsi bungalawulwa ngokulungelelanisa uxinzelelo kunye nesantya sokuhamba kwesixhobo esinyibilikisiweyo.

Ukuphola kunye nokuqina: Amathontsi ayaphola aze aqine ngokukhawuleza njengoko edlula kwigumbi lokutshiza. Izinga lokupholisa libalulekile njengoko lichaphazela isakhiwo se-micro kunye neempawu zomgubo ophumayo. Izinga lokupholisa elikhawulezayo ngokubanzi livelisa amasuntswana amancinci kunye nesakhiwo se-micro esifanayo.

Ukuqokelelwa kunye nokuHlelwa ngokweeNdawo: Emva kokuqina, umgubo wesinyithi uyaqokelelwa kwaye uhlelwe ngokobukhulu besuntswana. Oku kudla ngokwenziwa kusetyenziswa iindlela zokuhlola okanye zokwahlulahlula umoya. Imveliso yokugqibela inokulungiswa okongeziweyo, njengokusila okanye ukuxuba, ukuze kufunyanwe usasazo kunye neempawu zobukhulu besuntswana obufunekayo.

Ukucubungula emva: Ngokuxhomekeke ekusetyenzisweni, iipowder zesinyithi zinokufuna ukucutshungulwa ngakumbi, njengokugquma umphezulu okanye unyango lobushushu, ukuphucula iipropati zazo. Eli nyathelo libalulekile ukuqinisekisa ukuba ipowder iyahlangabezana neemfuno ezithile zokusetyenziswa okucetywayo.
