Ke Eng Cast Tungsten Carbide Powder

Cast tungsten carbide powder e na le sebopeho sa WC le W2C eutectic se bonts'ang ponahalo e bohlooho bo lefifi. Cast tungsten carbide powder e hlahisoa ke ts'ebetso e tsoetseng pele: tungsten ea tšepe le phofo ea tungsten carbide e tsoakoa ebe e kenngoa ka har'a seketsoana sa graphite. Hammoho, li futhumatsoa ka sebōping se qhibilihang ka 2900 ° C 'me li tšoaroa ka nako e itseng ho fumana sebaka sa ho lahlela se nang le likarolo tsa WC le W2C eutectic ka boholo ba lijo-thollo tsa 1 ~ 3 μm.

E bonts'a ts'ebetso e ikhethang ea ho roala le ho hanyetsa tšusumetso, hammoho le thepa ea boima bo phahameng, ka mocheso o phahameng. Boholo ba tungsten carbide particle bo tloha ho 0.038 mm ho isa ho 2.362 mm. Boima: 93.0 ~ 93.7 HRA; micro-thata: 2500 ~ 3000 lik'hilograma / mm2; boima ba 'mele: 16.5 g / cm3; sebaka se qhibilihang: 2525°C.

Lisebelisoa tsa cast tungsten carbide grits

1. Apara likarolo tse ka holimo (tse sa apereng) le liphahlo. Likarolo le likoahelo tse nang le pherekano, abrasion, cavitation, le khoholeho ea likaroloana joalo ka lisebelisoa tsa ho seha, lisebelisoa tsa ho sila, lisebelisoa tsa temo le likoahelo tse thata.

2. Diamond Tool Matrix. Li-powders tsa rona tsa tungsten carbide tse itokiselitseng ho kenella kapa tse chesang li sebelisoa e le phofo ea matrix ho tšoara le ho tšehetsa sesebelisoa sa ho seha taemane. Sets'oants'o se lumella ho pepeseha ha taemane ka botlalo ho hlokahalang bakeng sa ts'ebetso e ntle ea sesebelisoa.

Ho etsoa Mekhoa ea ho etsa phofo ea tungsten carbide

1. Thermal Spray Process. Li-girts tsa Cast tungsten carbide li ka fafatsoa ka mocheso ho etsa masela a thata holim'a bokaholimo bo hlokang ho eketseha ha khanyetso.

2. Ho kenella. Cast tungsten carbide, coarse tungsten metal, kapa tungsten carbide powders li kentsoe ka tšepe e metsi (e.g. copper-based alloy, bronze) ho etsa karolo. Li-powders tsa rona tsa cast tungsten carbide li na le bokhoni bo ikhethang ba ho kenella le litšoaneleho tsa moaparo tse lumellang bareki ba rona ho iketsetsa tharollo ea tlholisano bakeng sa bophelo bo eketsehileng ba ts'ebeletso le ho feto-fetoha ha moralo.

3. Powder Metallurgical (P/M). Li-powders tsa Cast tungsten carbide li hatelloa likarolong ka ho tobetsa ho chesang le ho sintering.

4. Plasma Transferred Arc (PTA) Welding. Ka lebaka la ho cheseha ho hoholo ha phofo ea cast tungsten carbide, hangata e sebelisoa ho lisebelisoa ka ts'ebetso ea tjheseletso ea PTA.

5. Dip Coatings. Liaparo tse joalo ka tse fumanoang ka li-electrode, lisebelisoa tsa ho cheka, le likarolo tse amanang le mecha ea phatlalatso ea abrasive li koahetsoe ka tungsten carbide e fanang ka qetello e thata ka ho feteletseng le ho hanyetsa ho apara.
