Silicon Carbide Whisker
Silicon carbide whisker( SiC-w ) ke lisebelisoa tse ncha tsa bohlokoa bakeng sa theknoloji e phahameng.Li tiisa ho tiea bakeng sa lisebelisoa tse tsoetseng pele tse kopaneng tse kang li-composites tsa tšepe, li-composites tsa motheo tsa ceramic le li-composites tse phahameng tsa polymer.E boetse e sebelisoa haholo ha ho etsoa lisebelisoa tsa ho itšeha ka ceramic, li-shuttle tsa sebaka, likarolo tsa likoloi, lik'hemik'hale, mechini le matla.
Litelu tsa SiC hajoale li sebelisoa lithulusing tse thata tsa ceramic.United States e atlehile ho hlahisa "litelu tsa SiC le liaparo tse nang le nano composite" bakeng sa liphahlo tse sa senyeheng, tse thibelang ho senya le tse phahameng tsa mocheso.Tlhokahalo ea 'maraka ea litelu tsa SiC e tla eketseha haholo mme tebello ea mmaraka e pharaletse haholo.
Litelu tsa silicon carbide li na le thepa e ntle ea mochini, ho hanyetsa mocheso, ho hanyetsa kutu, le ho hanyetsa mocheso o phahameng oa oxidation.Sehlahisoa se secha se tsamaellana hantle le lisebelisoa tsa matrix 'me se fetohile sesebelisoa se matla sa ntlafatso le se thata bakeng sa mefuta e fapaneng ea lisebelisoa tse kopaneng tsa ts'ebetso e phahameng lilemong tsa morao tjena.E sebelisoa haholo joalo ka tšepe, polasetiki, lisebelisoa tse kopaneng tsa ceramic.Li-composite tse matlafalitsoeng ke whisker ea silicon carbide li ka ntlafatsoa bakeng sa lits'ebetso tsa sefofane, sesole, merafo le metallurgy, indasteri ea lik'hemik'hale, likoloi, lisebelisoa tsa lipapali, lisebelisoa tsa ho itšeha, li-nozzles le likarolo tse hanyetsanang le mocheso o phahameng.Thepa e kopantsoeng ea silicon nitride ceramic matrix e matlafalitsoeng ka whisker e na le thepa e ntle haholo ea 'mele le ea mochini,' me e ka sebelisoa haholo liketsahalong tse fapaneng tse hananang le ho roala, ho hanyetsa mocheso o phahameng, ho se kutu, le liketsahalo tse hananang le tšusumetso ho kenyelletsa likarolo tsa enjene. ebile e na le litebello tse pharaletseng..Lisebelisoa tsa ho seha, lisakha tsa majoe, li-textile cutters, li-nozzles tsa sandblasting, mocheso o phahameng oa extrusion die, mehele ea ho tiisa, lihlomo, joalo-joalo li na le tlhokahalo e kholo ea 'maraka.
