Yenziwa njani intsimbi engumgubo?

Ukuveliswa kwesinyithi esinomguboibandakanya iindlela ezininzi eziphambili ezilungiselelwe ukufezekisa iipropathi ezithile kunye nokusetyenziswa. Makhe sihlolisise iindlela eziphambili ezisetyenziswa kule nkqubo.

Atomization

I-Atomization yenye yeendlela eziqhelekileyo zokuvelisa isinyithi somgubo. Iqala ngokunyibilika kwesinyithi esilahliweyo, esigalelwa ngeejethi zegesi okanye zamanzi. Esi senzo sichitha isinyithi esinyibilikisiweyo sibe ngamathontsi amancinane aqina phambi kokuba adibane.

Kukho iindlela ezimbini eziphambili ze-atomization: igesi kunye ne-atomization yamanzi. I-atomization yerhasi ivumela isinyithi esityhidiweyo ukuba sihlale sikwimeko yolwelo ixesha elide, sivumela ukubunjwa kwamasuntswana angqukuva. Le ndlela ivelisa umgubo ohamba kakuhle kunye nokuxinana okuphezulu. Ngakolunye uhlangothi, i-atomization yamanzi ipholisa ngokukhawuleza amaconsi, okubangela amaqhekeza amile ngokungaqhelekanga ngenxa yenkqubo yokuqinisa ngokukhawuleza. Indlela nganye inikezela ngeenzuzo ezizodwa ngokuxhomekeke kwiipropati ezifunwayo zetsimbi yomgubo.

Ukunciphisa kunye ne-Electrolysis

Ukunciphisa kubandakanya ukuphendula kweekhemikhali ezikhupha isinyithi kwintsimbi yayo. Intsimbi ekrwada iyatyunyuzwa, ixutywe nekhabhoni, ize ifudunyezwe kwiziko. Le nkqubo inciphisa ioksijini kunye namanqanaba ekhabhoni, ishiya ngasemva isinyithi esifana nesipontshi. Ukunciphisa i-Solid-state ilandela indlela efanayo, apho umxube we-ore-carbon udlula kwisithando somlilo, uvelisa isinyithi se-sponge kunye nokungcola okuncitshisiweyo.

I-Electrolysis yenye indlela eqinisekisa ukucoceka okuphezulu. Ngokusebenzisa iindlela ezilawulwayo zokubeka i-electrodeposition, le nkqubo idala ii powders zetsimbi ezisebenziseka lula kwaye zilungele izicelo ezifuna ubunyulu obukhethekileyo.

I-alloying yomatshini idibanisa iintsimbi ezahlukeneyo zibe ngumgubo omnye. Le nkqubo isebenzisa iibhola zebhola eziphezulu zamandla ukuze ziqhekeze ngokuphindaphindiweyo kwaye zidibanise iincinci zentsimbi kunye. Ngokuhamba kwexesha, iintsimbi zidibanisa kwinqanaba le-microscopic, zenza i-alloy efanayo. Le ndlela iluncedo kakhulu ekudaleni ukomelela okuphuculweyo kunye nokuqina kwemathiriyeli edibeneyo.

I-Sintering kunye noVeliso oloNgezelelweyo

I-Sintering idlala indima ebalulekileyo ekubumbeni nasekomelezeniiimveliso zetsimbi ezinomgubo. Ngethuba le nkqubo, i-compact eluhlaza (ifom ye-powder ecinezelweyo) ishushu ukuze idibanise iinqununu. Eli nyathelo lisusa izithambiso, linyusa ukuxinana, kwaye liphucula iimpawu zomatshini njengamandla kunye nokuqina. Njengoko ubukhulu be-pore buncipha, izinto eziphathekayo zifezekisa ubuninzi obufunwayo kunye ne-conductivity.

Imveliso eyongezelelweyo, okanyeUshicilelo lwe-3D, isebenzisa intsimbi engumgubo ukwenza iimilo ezintsonkothileyo umaleko ngokomaleko. Obu buchule bokusungula buvumela ukwenziwa okuchanekileyo kunye nokunciphisa inkunkuma yempahla, iyenze ibe lukhetho oludumileyo kumashishini afana ne-aerospace kunye nokhathalelo lwezempilo.

Imveliso yesinyithi yomgubo idibanisa isayensi kunye nobunjineli ukuhambisa izinto eziguquguqukayo kwimveliso yanamhlanje. Ukuqonda ezi nkqubo kugxininisa ubukrelekrele obusemva kwesinyithi esinomgubo kunye namandla aso okuguqula.
