Mokhoa oa ho Hlahisa Malebela a Carbide

I. Taolo ea lisebelisoa tse tala le tse thusang.

1. Lintho tse tala tsa tungsten carbide phofo le phofo ea cobalt li tla lekoa pele li sebelisoa ho etsa lisebelisoa tsa tungsten carbide. Re tla sebelisa tlhahlobo ea metallographic, ho lekoa hore boholo ba likaroloana tsa WC bo fetoha ka har'a mefuta e itseng, 'me ka nako e ts'oanang, likarolo tsa trace le k'habone kaofela li laoloa ka thata.

2. Teko ea ho sila bolo e etsoa bakeng sa sehlopha se seng le se seng sa WC e rekiloeng, 'me lintlha tsa motheo tse kang ho thatafala, matla a ho kobeha, magnetism ea cobalt, matla a qobellang, le boima ba 'mele li hlahlojoa ho utloisisa ka botlalo litšobotsi tsa eona tsa' mele.

II. Taolo ea ts'ebetso ea tlhahiso.

1. Ho sila ka bolo le ho kopanya, e leng mokhoa oa granulation, o khethollang karo-karolelano e hlephileng le fluidity ea motsoako. Khamphani ea rona e nka lisebelisoa tsa morao-rao tse tsoetseng pele tsa granulation ho rarolla hantle metsi a motsoako.

2. Ho hatella, e leng mokhoa oa ho etsa lihlahisoa, re sebelisa mochine oa khatiso oa othomathike kapa TPA ho hlahisa, Ka hona ho fokotsa tšusumetso ea lintlha tsa batho ho embryo e hatellang.

3. Sintering, Khamphani ea rona e sebelisa theknoloji ea sintering ea khatello e tlaase ho etsa bonnete ba hore ho na le sepakapaka se tšoanang ka sebōping, le ho laola ka mokhoa o itekanetseng oa ho futhumatsa, ho futhumatsa, ho pholisa, le ho leka-lekana ha carbon ka mokhoa oa sintering.

III. Tlhahlobo ea lihlahisoa.

1. Ntlha ea pele, re tla sebelisa sandblasting kapa passivation ea malebela a samente ea carbide ho pepesa ka botlalo lihlahisoa tse nang le bokooa.

2. Joale, re tla etsa tlhahlobo ea metallographic ea fracture holim'a sehlahisoa, Kahoo ho etsa bonnete ba hore ho na le sebopeho sa ka hare se ts'oanang.

3. Litlhahlobo tsohle le litlhahlobo tsa likarolo tsa 'mele le tsa tekheniki, ho kenyelletsa le boima, matla, cobalt magnetism, matla a khoheli, le matšoao a mang a botekgeniki, Qetellong a fihlela litlhoko tse tsamaellanang le sehlopha.

4. Ka mor'a liteko tsohle, re tla etsa tlhahlobo ea welding ea sehlahisoa ho netefatsa botsitso ba ts'ebetso ea welding.

Ena ke mokhoa oa ho hlahisa malebela ana a manyane a carbide, E rarahane empa e bohlokoa.
