Hot Isostatic Pressing (HIP) ke Eng?
Hot Isostatic Pressing (HIP) ke Eng?
Ha re etsa lihlahisoa tsa tungsten carbide, re lokela ho khetha thepa e ntle ka ho fetisisa e tala, tungsten carbide powder le binder powder, hangata cobalt phofo. Kopanya le ho sila bona, ho omisa, ho hatella, le ho sila. Nakong ea sintering, kamehla re na le likhetho tse fapaneng. 'Me sehloohong sena, re tla bua ka hot isostatic pressing sintering.
Hot Isostatic Pressing ke Eng?
Hot Isostatic Pressing, eo hape e tsejoang e le HIP, ke e 'ngoe ea mekhoa ea ho lokisa thepa. Nakong ea ho chesa ha isostatic sintering, ho na le mocheso o phahameng le khatello ea isostatic.
Khase e sebelisoang ho sintering e chesang ea isostatic
Argon gas e sebelisoa ho hot isostatic pressing sintering. Sebōping sa sintering, ho na le mocheso o phahameng le khatello e phahameng. Khase ea Argon e kanna ea baka convection e matla ka lebaka la letsoalo le tlase le coefficient of viscosity, le li-coefficients tse phahameng tsa katoloso ea mocheso. Ka hona, li-coefficients tsa mocheso oa mocheso oa lisebelisoa tse chesang tsa isostatic li phahame ho feta tsa sebōpi sa setso.
Ts'ebeliso ea sintering e chesang ea isostatic
Ntle le ho etsa lihlahisoa tsa tungsten carbide, ho na le lisebelisoa tse ling tsa hot isostatic pressing sintering.
1. Khatello sintering ea matla.
Mohlala. Li-alloys tsa Ti li entsoe ke hot isostatic sintering ho etsa karolo ea sefofane.
2. Diffusion bonding ea mefuta e fapaneng ea thepa.
Mohlala. Likopano tsa peterole ea nyutlelie li etsoa ke hot isostatic pressing sintering hore li sebelisoe ka li-reactors tsa nyutlelie.
3. Ho tlosoa ha li-pores tse setseng ka lintho tse sintered.
Mohlala. Tungsten carbide le lisebelisoa tse ling, joalo ka Al203, li entsoe ke ho chesa isostatic sintering ho fumana thepa e phahameng, joalo ka boima bo phahameng.
4. Ho tlosoa ha mefokolo ea ka hare ea li-castings.
Al le superalloys li entsoe ke hot isostatic pressing sintering ho tlosa mefokolo e ka hare.
5. Ho tsosolosoa ha likarolo tse senyehileng ke mokhathala kapa ho tsuba.
6. Mekhoa e phahameng ea khatello e kentsoeng ka carbonization.
Lisebelisoa tse fapaneng tsa ho etsoa ka ho tobetsa ho chesang ha isostatic
Kaha hot isostatic pressing sintering e na le lits'ebetso tse ngata, e ka sebelisoa ho etsa mefuta ea lisebelisoa. Lisebelisoa tse fapaneng li na le litšobotsi tse fapaneng tsa 'mele le lik'hemik'hale, kahoo li na le litlhoko tse fapaneng bakeng sa maemo a sintering. Re tlameha ho fetola mocheso le khatello ea thepa e fapaneng. Mohlala, Al2O3 e hloka 1,350 ho isa ho 1,450°C le 100MPa, mme Cu alloy e kopa 500 ho isa ho 900°C le 100MPa.
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.
