Tlhahisong ea liindasteri, liphaephe li tšoana le “lijana tsa mali” tse tsoelang pele ho tsamaisa thepa e kang seretse sa tšepe, phofo ea mashala le masalla a litšila. Leha ho le joalo, boholo ba lisebelisoa tsena li na le litšobotsi tsa boima bo phahameng le lebelo la ho phalla ka potlako. Liphaephe tse tloaelehileng li tla tloha li khathatsoa ke ho lutla, tse sa hlokeng feela hore li koaloe khafetsa le ho nchafatsoa, empa hape li ka baka likotsi tsa polokeho ka lebaka la ho lutla ha thepa. Ho hlaha ha liphaephe tse manganga tsa silicon carbide ke ho rarolla "bothata ba ho roala".
Batho ba bang ba ka 'na ba botsa, "silicon carbide" ke thepa ea mofuta ofe? Ha e le hantle, hase ntho e ncha. Ha e le hantle, ke ntho e sa sebetseng ea tšepe e entsoeng ka silicon le likarolo tsa carbon, tse nang le bothata ba bobeli ho daemane le corundum. Li-sandpaper tse ngata tsa boemo bo holimo le lisebelisoa tsa ho sila tse atisang ho sebelisoa bophelong ba letsatsi le letsatsi li sebelisa silicon carbide. Ha thepa ena e thata haholo e etsoa lebotang le ka hare la phaephe, ho tšoana le ho beha moalo oa “lihlomo tsa daemane” phaepeng. Ha e shebane le lisebelisoa tse phahameng tsa ho roala, e ka hanela ka ho toba tšusumetso le likhohlano tsa thepa, ha e le hantle e atolosa bophelo ba tšebeletso ea pipeline.
Ha ho bapisoa le liphaephe tsa setso, melemo ea liphaephe tse manganga tsa silicon carbide li feta "ho hanyetsa ho roala". Liphaephe tse tloaelehileng tsa tšepe li senyeha habonolo ke lintho tse senyang nakong ea lipalangoang, 'me liphaephe tsa polasetiki li thata ho mamella mocheso o phahameng le likhatello. Leha ho le joalo, thepa ea silicon carbide ka boeona e na le litšobotsi tsa ho hanyetsa acid le alkali le ho hanyetsa mocheso o phahameng. Ebang ba tsamaisa slurry ea acidic kapa phofo ea mashala a mocheso o phahameng, ba ka sebetsa ka mokhoa o tsitsitseng ntle le ho tšoenyeha khafetsa ka "corrosion perforation" kapa "high-themperature deformation". Habohlokoa le ho feta, lerako la eona le ka hare le boreleli, le etsa hore ho se be bonolo ho bokella le ho thibela nakong ea lipalangoang tsa thepa, ho fokotsa bothata ba ho hloekisa liphaephe le ho etsa bonnete ba hore tlhahiso e tsoela pele.
Matsatsing ana, liindastering tse kang tsa merafo, motlakase le boenjineri ba lik'hemik'hale tse hlokang hore liphaephe li se ke tsa senyeha haholo, butle-butle liphaephe tse sa keneng tsa silicon carbide li nkile sebaka sa lipeipi tsa setso. Ha ho hlokahale hore e nkeloe sebaka ka mor'a likhoeli tse ling le tse ling tse tšeletseng joaloka liphaephe tse tloaelehileng, ebile ha e hloke litšenyehelo tse pheta-phetoang tsa tlhokomelo. Leha matsete a pele a ka bonahala a phahame hanyane, a thusa khoebo ho boloka litšenyehelo tse ngata ha nako e ntse e ea. Bakeng sa likhoebo tse hahamallang tlhahiso e sebetsang hantle le e tsitsitseng, ho khetha liphaephe tse sa keneng tsa silicon carbide ha e le hantle ke ho khetha tharollo ea lipalangoang e "tšoenyehang, e tšoarellang nako e telele".
Ka tlhokahalo e ntseng e eketseha ea ho tšoarella ha lisebelisoa le polokeho tlhahisong ea indasteri, maemo a ts'ebeliso ea liphaephe tse hananang le silicon carbide a ntse a hola khafetsa. E rarolla bothata ba "khale le bo boima" ho lipalangoang tsa indasteri ka ts'ebetso e thata ea mantlha ea thepa ka boeona, hape e fana ka likhoebo tse ngata ka khetho e tšepahalang tseleng ea ho fokotsa litšenyehelo le ntlafatso ea katleho.
