Pores ka mor'a Sintering

Carbide e entsoeng ka samente ke mofuta oa motsoako o nang le tungsten e lekanang le carbon, e nang le bothata bo haufi le taemane. Carbide e entsoeng ka samente e na le boima bo phahameng le boima bo phahameng ka nako e le 'ngoe. Carbide e entsoeng ka samente e entsoe ka metallurgy ea phofo, 'me sintering ke ts'ebetso ea bohlokoa ka ho fetisisa nakong ea ho etsa sehlahisoa sa carbide se entsoeng ka samente. Ho bonolo ho baka li-pores ka mor'a hore tungsten carbide sintering haeba e sa laoloe hantle. Sehloohong sena, u tla fumana lintlha tse ling mabapi le li-pores ka mor'a hore tungsten carbide sintering.

Tungsten carbide powder le binder powder li kopantsoe ka tekanyo e itseng. Ebe motsoako oa phofo o etsoa ka botala bo botala ka mor'a ho sila ka metsi ka mochine oa leloala la bolo, ho omisa le ho kopanya. Li-compact tungsten carbide tse tala li tšeloa ka har'a sebōpi se chesang sa HIP.

Mokhoa o ka sehloohong oa sintering o ka aroloa ka mekhahlelo e mene. Ke ho tlosoa ha molding agent le pre-sintering stage, solid-phase sintering stage, liquid-phase sintering stage, le cooling sintering stage. Nakong ea sintering, mocheso o ntse o eketseha butle-butle. Ka lifeme, ho na le mekhoa e 'meli e tloaelehileng ea ho sintering. E 'ngoe ke hydrogen sintering, eo ho eona ho hlophisoa ha likarolo ho laoloang ke phase reaction kinetics ka hydrogen le khatello ea sepakapaka. 'Me e' ngoe ke vacuum sintering, e sebelisang tikoloho ea vacuum kapa tikoloho e fokotsehileng. Khatello ea khase e laola sebopeho sa carbide e entsoeng ka samente ka ho liehisa kinetics ea karabelo.

Ke feela ha basebetsi ba laola sethala ka seng ka hloko, lihlahisoa tsa ho qetela tsa tungsten carbide li ka fumana microstructure e lakatsehang le metsoako ea lik'hemik'hale. Li-pores tse ling li ka ba teng ka mor'a ho sintering. Le leng la mabaka a bohlokoa ke mabapi le mocheso oa sintering. Haeba mocheso o phahama ka potlako, kapa mocheso oa sintering o phahame haholo, kholo ea lijo-thollo le motsamao o tla be o sa lekane, e leng se fellang ka ho hlahisa li-pores. Lebaka le leng la bohlokoa ke moemeli oa ho theha. Binder e tlameha ho tlosoa pele e sintering. Ho seng joalo, moemeli oa ho etsa o tla volatilize nakong ea mocheso o ntseng o eketseha oa sintering, o tla fella ka li-pores.

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 letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
