Mokhoa oa ho etsa Sintering Tungsten Carbide
Mokhoa oa ho etsa Sintering Tungsten Carbide
Joalo ka ha bohle re tseba, tungsten carbide ke e 'ngoe ea lisebelisoa tse thata ka ho fetisisa tse sebelisoang indastering ea sejoale-joale. Ho etsa tlhahiso ea tungsten carbide, e tlameha ho ba le mekhoa e mengata ea liindasteri, joalo ka ho kopanya phofo, ho sila ka metsi, ho omisa ka spray, ho hatella, sintering le ho hlahloba boleng. Nakong ea sintering, molumo oa carbide e entsoeng ka samente e tla fokotseha ka halofo. Sengoliloeng sena ke ho tseba se etsahetseng ka tungsten carbide nakong ea sintering.
Nakong ea sintering, ho na le mekhahlelo e mene eo tungsten carbide e lokelang ho ba le eona. Ke:
1. Ho tlosoa ha mochine oa ho bōpa le sethaleng sa ho chesa pele;
2. Mokhahlelo o tiileng oa sintering;
3. Mokhahlelo oa sintering oa mokelikeli;
4. Sethala sa ho pholile.
1. Ho tlosoa ha mochine oa ho bōpa le sethaleng sa ho chesa pele;
Ts'ebetsong ena, mocheso o lokela ho eketseha butle-butle, 'me mohato ona o etsahala ka tlase ho 1800 ℃. Ha mocheso o ntse o eketseha, mongobo, khase le mokelikeli o setseng ka har'a tungsten carbide e hatelitsoeng li fetoha mouoane butle-butle. Moemeli oa ho bōpa o tla eketsa carbon content ea sintering cemented carbide. Ho sintering e fapaneng, keketseho ea litaba tsa carbide e fapane. Khatello ea ho kopana pakeng tsa likaroloana tsa phofo e boetse e tlosoa butle-butle nakong ea ho eketseha ha mocheso.
2. Mokhahlelo o tiileng oa sintering
Ha mocheso o ntse o eketseha butle-butle, sintering e tsoela pele. Sekhahla sena se etsahala lipakeng tsa 1800 ℃ le mocheso oa eutectic. Ho thoeng ke mocheso oa eutectic o bolela mocheso o tlaase ka ho fetisisa oo mokelikeli o ka bang teng tsamaisong ena. Mokhahlelo ona o tla tsoelapele ho ipapisitse le mothati oa ho qetela. Phallo ea polasetiki e eketseha 'me' mele oa sintered o fokotseha haholo. Ka nako ena, molumo oa tungsten carbide o fokotseha ka ho hlaka.
3. Mokelikeli mohato sintering sethaleng
Nakong ena, mocheso o nyoloha ho fihlela o fihla mocheso o phahameng ka ho fetisisa nakong ea sintering, mocheso oa sintering. Ha karolo ea mokelikeli e hlaha ho tungsten carbide, shrinkage e qetella ka potlako. Ka lebaka la tsitsipano ea holim'a karolo ea mokelikeli, likaroloana tsa phofo li atamelana, 'me li-pores ka likaroloana li tlala butle-butle ka karolo ea mokelikeli.
4. Sethala sa ho pholile
Ka mor'a ho chesa, carbide e entsoeng ka samente e ka tlosoa sebōping sa sintering 'me ea pholile mocheso oa kamore. Lifeme tse ling li tla sebelisa mocheso oa litšila seboping sa sintering bakeng sa tšebeliso e ncha ea mocheso. Nakong ena, ha mocheso o theoha, ho thehoa microstructure ea ho qetela ea alloy.
Sintering ke ts'ebetso e thata haholo, 'me zzbetter e ka u fa tungsten carbide ea boleng bo holimo. Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka ho le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
