Ziziphi izinto zeMetal zePowder?

Ziziphi izinto zeMetal zePowder? Amalungu esinyithi enziwe ngomgubo enziwa kusetyenziswa intsimbi engumguboinkqubo eyodwa eyaziwa ngokuba yi powder metallurgy. Obu buchule bubandakanya ukucinezela kunye nokutshiza umgubo wentsimbi ukuvelisa iindawo ezintsonkothileyo nezichanekileyo.

I-metallurgy yomguboiphawuleka ngesakhono sayo sokudala iijiyometri ezintsonkothileyo kunye nokudibanisa ii-sub-assemblies ezininzi zibe yinto enye, edibeneyo. Oku akuncitshi kuphela iindleko zendibano kodwa kukwaphucula nentembeko yesakhiwo.

Imizi-mveliso efana nezeemoto, i-aerospace, kunye nenkathalo yezempilo iya isanda ngokwamkela la macandelo ngenxa yokusebenza kwawo ngempumelelo kunye nokuguquguquka. Ukongeza, inkqubo ikhuthaza ukwenziwa okuzinzileyo ngokunciphisa inkcitho yezinto eziphathekayo kunye nokugcina amandla.

Zenziwa Njani Izinto Zentsimbi Yomgubo?

Ukudala i-powder metal components kubandakanya ngokuchanekileyo, inkqubo yamanyathelo amaninzi eqinisekisa iziphumo eziphezulu. Makhe ndikuhambise kumanqanaba aphambili.

Ukuveliswa komgubo kunye nokudibanisa

Uhambo luqala ngokuvelisa umgubo wentsimbi. Abavelisi basebenzisa iindlela ezifana ne-atomization, ukucola, okanye ukuphendula kweekhemikhali ukwenza amasuntswana esinyithi. Ezi powders ke zixutywe kwaye zixutywe ukufezekisa iimpawu ezifunwayo. Ukudibanisa kudibanisa i-powders yeekhemistri ezahlukeneyo, ngelixa ukudibanisa kuqinisekisa ukufana kobukhulu kunye nokubunjwa. Eli nyathelo libaluleke kakhulu kuba limisela iimpawu zecandelo lokugqibela, njengamandla kunye nokuqina.

Inkqubo yoQhagamshelwano

Okulandelayo kuza inkqubo yokudibanisa, apho umgubo odibeneyo uthatha imilo. Ndilibonile eli nyathelo lisebenzisa ubuchule obufana nokudibanisa ukufa, ukucinezela kwe-isostatic ebandayo (CIP), okanye ukucinezela kwe-isostatic eshushu (HIP). Umzekelo, i-die compaction isebenzisa i-punch ukucinezela umgubo ube ngumbumba, wenze "i-compact eluhlaza." I-CIP isebenzisa uxinzelelo ngokufanayo ukusuka macala onke, iyenza ilungele iimilo ezintsonkothileyo. Ukugcina uxinzelelo oluhambelanayo ngeli nqanaba liqinisekisa ukuba i-particle bond mechanically, okubangelwa isakhiwo esixineneyo nesifanayo.

I-Sintering kunye neNkqubo yokuGqibela

Inyathelo lokugqibelaukucula, apho i-powder edibeneyo ifudumala ngaphantsi kwendawo yokunyibilika kwayo. Le nkqubo idibanisa amaqhekeza kunye, ukudala icandelo eliqinileyo. Izinto ezifana nexesha, ubushushu kunye nomoya zidlala indima ebalulekileyo apha. Amaxesha amade e-sintering aphucula i-particle bonding, ngelixa umoya olawulwayo ukhusela i-oxidation. Emva kokuntywila, iindlela ezongezelelekileyo ezifana nonyango lobushushu okanye ukungeniswa ziphucula iipropathi zenxalenye, ezinje ngamandla kunye nokuxinana.

Ngokulandela la manyathelo, abavelisi bavelisa amacandelo achanekileyo aphezulu kunye nenkunkuma encinci. Le nkqubo ibonisa ukuba kutheni i-powder metallurgy ikhethwa kumashishini afuna ukusebenza kakuhle kunye nokuzinza.
