Yiziphi Izingxenye Ze-Powder Metal?

Yiziphi Izingxenye Ze-Powder Metal? Izingxenye zensimbi zempuphu zenziwa kusetshenziswa insimbi eyimpuphu ngokusebenzisainqubo eyingqayizivele eyaziwa ngokuthi i-powder metallurgy. Le nqubo ihlanganisa ukucindezela kanye nokucwilisa izimpushana zensimbi ukuze kukhiqizwe izingxenye eziyinkimbinkimbi, ezinembe kakhulu.

I-powder metallurgyiphawuleka ngamandla ayo okudala amajiyometri ayinkimbinkimbi futhi ihlanganise ama-sub-assembly amaningi abe yingxenye eyodwa, ebumbene. Lokhu akunciphisi kuphela izindleko zokuhlanganisa kodwa futhi kuthuthukisa ubuqotho besakhiwo.

Izimboni ezifana nezezimoto, i-aerospace, nokunakekelwa kwezempilo ziya ngokuya zamukela lezi zingxenye ngenxa yokusebenza kahle kwazo nokuguquguquka. Ukwengeza, le nqubo ikhuthaza ukukhiqizwa okusimeme ngokunciphisa ukumoswa kwezinto ezibonakalayo nokonga amandla.

Zenziwa Kanjani Izingxenye Zensimbi Ye-Powder?

Ukudala izingxenye zensimbi ye-powder kuhilela inqubo eqondile, enezinyathelo eziningi eqinisekisa imiphumela yekhwalithi ephezulu. Ake ngikuhambise ezigabeni ezibalulekile.

Ukukhiqizwa Kwempushana kanye Nokuxutshwa

Uhambo luqala ngokukhiqiza izimpushana zensimbi. Abakhiqizi basebenzisa izindlela ezifana ne-atomization, ukugaya, noma ukusabela kwamakhemikhali ukuze bakhe izinhlayiya zensimbi ezinhle. Lezi zimpushana zibe sezixutshwa futhi zixutshwe ukuze kuzuzwe izici ezifunwayo. Ukuxuba kuhlanganisa izimpushana zamakhemikhali ahlukene, kuyilapho ukuhlanganisa kuqinisekisa ukufana ngosayizi nokubunjwa. Lesi sinyathelo sibalulekile ngoba sinquma izici zengxenye yokugcina, njengamandla nokuqina.

Inqubo Yokubamba

Okulandelayo kuza inqubo yokuhlanganisa, lapho impushana ehlanganisiwe iba khona. Ngibone lesi sinyathelo sisebenzisa amasu afana ne-die compaction, cold isostatic pressing (CIP), noma hot isostatic pressing (HIP). Isibonelo, i-die compaction isebenzisa i-punch ukuze icindezele impushana ibe yisikhunta, yenze "i-compact eluhlaza." I-CIP isebenzisa ingcindezi ngokufanayo kuzo zonke izinhlangothi, iyenze ilungele izimo eziyinkimbinkimbi. Ukugcina ukucindezela okungaguquki phakathi nalesi sigaba kuqinisekisa isibopho sezinhlayiya ngomshini, okuholela ekwakhiweni okuminyene futhi okufanayo.

I-Sintering kanye Nokucubungula Kokugcina

Isinyathelo sokugcinaukucula, lapho impushana ehlanganisiwe ishiselwa ngaphansi kwendawo yayo yokuncibilika. Le nqubo ihlanganisa izinhlayiya ndawonye, ​​​​yakha ingxenye eqinile. Izinto ezifana nesikhathi, izinga lokushisa, nomoya zidlala indima ebalulekile lapha. Izikhathi ezinde ze-sintering zithuthukisa ukuhlangana kwezinhlayiyana, kuyilapho umoya olawulwayo uvimbela i-oxidation. Ngemuva kokucwilisa, amasu angeziwe afana nokwelashwa kokushisa noma ukungena athuthukisa izici zengxenye, njengamandla nokuminyana.

Ngokulandela lezi zinyathelo, abakhiqizi bakhiqiza izingxenye ezinembe kakhulu ezinodoti omncane. Le nqubo igqamisa ukuthi kungani i-powder metallurgy ikhethwa ezimbonini ezifuna ukusebenza kahle nokusimama.

Izinzuzo ze-Powder Metal Components

Ukusebenza Kahle Kwezindleko Nokumosha Okuncishisiwe

I-powder metallurgy igqama njengeindlela yokukhiqiza engabizi kakhulu. Ngizibonele mathupha ukuthi inciphisa kanjani imfucuza futhi inciphisa izindleko uma kuqhathaniswa namasu omdabu. Nasi isizathu:

• Inqubo isebenzisa ngaphezu kwama-97% wezinto zokuqala zokusetshenziswa emkhiqizweni wokugcina, yehlisa kakhulu ukulahlekelwa kwezilahliwe.
