Nka u ka har'a tungsten carbide porosity

Tungsten carbide ke thepa e teteaneng le e thata e sebelisoang hangata lits'ebetsong tse fapaneng tsa indasteri ka lebaka la thepa ea eona e ikhethang joalo ka matla, ho hanyetsa ho roala le ho thatafala.Leha ho le joalo, joalo ka ntho leha e le efe, ha e khonehe ka ho feletseng ho se phethahale, 'me porosity ke e' ngoe ea litaba tse tloaelehileng tse amanang letungsten carbide.

Porosity katungsten carbidee bua ka boteng ba likheo, mapetsong, kapa likheo ka har'a thepa e ka fokolisang sebopeho le ts'ebetso ea eona ka kakaretso.Li-pores tsena li ka bakoa ke lintlha tse sa tšoaneng, tse kenyelletsang mekhoa e sa nepahalang ea tlhahiso, ho se lumellane ha lihlahisoa tse sebelisoang, le ho fapana ha mokhoa oa sintering.

Porosity ho tungsten carbide e ka ba le tšusumetso e kholo ho thepa le ts'ebetso ea eona.Porosity e phahameng e ka fokotsa matla a thepa, ho thatafala le ho tiea, ho etsa hore ho be bonolo ho peperana le ho senyeha.Ho phaella moo, porosity e ka ama bokhoni ba thepa ea ho tsamaisa mocheso, e leng se ka lebisang litabeng tse kang ho phatloha ha mocheso le deformation.

Ho fokotsa porosity ho tungsten carbide, bahlahisi ba ka sebelisa mekhoa e ikhethang joalo ka ho tobetsa isostatic e chesang, e ka thusang ho koala li-pores leha e le life tsa thepa.Ho hatella ho chesang ha isostatic ho kenyelletsa ho sebelisa khatello e phahameng le mocheso ho thepa ea tungsten carbide, e thusang ho felisa likheo, likheo kapa mapetsong a thepa.Ka kakaretso,

porosity ke taba e tloaelehileng e amanang le tungsten carbide, empa e ka fokotsoa ka ho sebelisa mekhoa le mekhoa e nepahetseng ea tlhahiso, le ka ho khetha lisebelisoa tse tala tsa boleng bo phahameng.
