Carbide le ho lokisetsa cermet

Li-alloys tse thata tsa WC-Co li khona ho ikamahanya le maemo ka microwave.Nakong ea ts'ebetso ea sintering, mekhoa ea tahlehelo e sebetsang sebakeng sa mocheso o tlase haholo-holo ke tahlehelo ea ho phomola ha polarization le tahlehelo ea makenete, ha sebakeng sa mocheso o phahameng motsoako o monya matla a microwave.Haholo-holo ka mokhoa oa tahlehelo ea dielectric le tahlehelo ea conductivity.

Themotsoakoka kenyelletso ea 0.4% VC le 0.2% Cr3C2 (karolo ea boima) e le lisebelisoa tse thusang li na le ts'ebetso e ntle ka ho fetisisa;tšebeliso ea vacuum microwave sintering e ntlafatsa haholo ts'ebetso ea motsoako.Ho sebelisa sintering ea microwave e nang le li-cavity tse ngataWC-8Co, e chesoa ka mocheso oa 1400 ° C ntle le ho boloka mocheso.Boima ba eona bo ka fihla ho 14.71g / cmHRA e fihla90.3, 'me sebopeho se tšoana.

Theknoloji ea sintering ea microwave e ka sebelisoa ho lokisa li-cermets tse ntle haholo tse nang le lijo-thollo tse ntle, sebopeho se ts'oanang le ts'ebetso e ntle haholo.Ha mocheso oa sintering o ntse o eketseha, ho fokotseha, ho teteaneng, matla a ho feto-fetoha le ho thatafala ha li-cermets tsa ultra-fine ho qala ho eketseha ebe ho fokotseha, ka boleng bo phahameng bo hlahang ho 1500 ° C;e loketseng microwave sintering process for Ultra-fine cermets Ka mor'a ho bolokoa ho 1500 ° C metsotso e 30, matla a flexural le hardness values ​​ke 1547MPa le 90.6HRA ka ho latellana, tse eketsehileng ka 24.0% le 0.7% ka ho latellana ha ho bapisoa le sintering e tloaelehileng.
