Phofo ea tšepe ke eng?

Pokello ea likaroloana tsa tšepe tse ka tlase ho millimeter e le 'ngoe e bitsoa phofo ea tšepe. Ena ke thepa ea mantlha e sebelisoang ho metallurgy ea phofo 'me e kenyelletsa tšepe e le' ngoe, alloy, le phofo e itseng ea refractory composite e nang le litšobotsi tsa tšepe.

Likarolo tsa tšepe ea phofo ke eng?

Ts'ebetso ea likarolo tsa phofo ea tšepe ke ho etsa tšepe kapa ho sebelisa phofo ea tšepe (kapa phofo ea tšepe le motsoako o se nang tšepe) e le lisebelisoa tse tala, ka mor'a ho etsa le MIM sintering, ho etsa thepa ea tšepe, lisebelisoa tse kopantsoeng le mefuta e sa tšoaneng ea theknoloji ea lihlahisoa. Indasteri ea likarolo tsa tšepe e akaretsang e kenyelletsa lisebelisoa tsa tšepe le majoe, carbide e entsoeng ka samente, lisebelisoa tsa makenete. Ka kutloisiso e moqotetsane, Indasteri ea likarolo tsa phofo e bua ka lihlahisoa tsa metallurgy feela, ho kenyeletsoalikarolo tsa phofo ea metallurgy(e ikarabellang bakeng sa bongata bo boholo), e nang le oli lelihlahisoa tsa ho bopa ente ea tšepe.

• boima ba sehlahisoa bo khona ho laoleha, joalo ka lisebelisoa tsa porous, lisebelisoa tse ntle tsa boima ba 'mele;
• lijo-thollo tse ntle, microstructure e tšoanang, ha ho na karohano ea likarolo;
• haufi le ho theha, sekhahla sa tšebeliso ea thepa e tala> 95%;
• tlase ha ho ho itšeha, ho itšeha ho sebetsa feela 40 ~ 50%;
• ho hlophisoa ha thepa ho laoleha, e leng se loketseng ho lokisoa ha lisebelisoa tse kopantsoeng;
• ho lokisa tšepe ea refractory, lisebelisoa tsa ceramic le lisebelisoa tsa nyutlelie.

Likarolo tsa tšepe tsa phofo tsa motheo tsa mokhoa oa ho phalla

1, Ho phunya

Pulverizing ke mokhoa oa ho etsa thepa e tala hore e be phofo. Mekhoa e sebelisoang hangata ea ho phunya ke mokhoa oa ho fokotsa oxide le mokhoa oa mochini.

2, Ho kopanya

Ho kopanya ke mokhoa oa ho etsa phofo ea billet ka ho kopanya mefuta eohle ea phofo e hlokahalang ka tekanyo e itseng le ho e etsa homogenizing. E arotsoe ka tse tharo tse omeletseng, tse omeletseng le tse metsi, ka ho latellana bakeng sa litlhoko tse fapaneng.

3, Ho theha

Ho theha ke mokhoa oa ho etsa sekheo se nang le sebopeho se itseng, boholo le boima ka ho kenya thepa e tsoakiloeng ka mokhoa o ts'oanang ka har'a mochine o hatellang tlas'a khatello e boima. Molding mokhoa ha e le hantle o arotsoe ka ho bopa khatello 'me ha ho khatello ea khatello. Ho bopa ha khatello ke eona e sebelisoang haholo ho bopa.

4, Sintering

5. Ka mor'a ts'ebetso

  Ka mor'a ho phekola sintering, ho ea ka litlhoko tse fapaneng tsa likarolo tsa tšepe tsa phofo, nka litsela tse sa tšoaneng. Joalo ka ho qeta, ho qoela, ho sebetsa ka mechine, ho phekola mocheso le electroplating. Ho phaella moo, lilemong tsa morao tjena, mekhoa e meng e mecha e kang ho roala le ho qhekella le eona e 'nile ea sebelisoa ho sintering ea lisebelisoa tsa metallurgy ea phofo' me ho fihletsoe liphello tse molemo.

Ho sila ka phofo ke ts'ebetso ea bohlokoa ts'ebetsong ea metallurgy ea phofo. Ka mor'a ho theha, billet e sintered ho fumana thepa ea ho qetela ea 'mele le ea mechine e lakatsehang. Sintering in metallurgy e arotsoe ka unit sintering le multi-system sintering. Ho phaella ho sintering e tloaelehileng, ho na le sintering e hlephileng, ho qoelisoa, ho hatella ho chesang le mekhoa e meng e khethehileng ea sintering.
