Litšobotsi tse ka sehloohong

T800 ke e 'ngoe ea li-alloys tse sebelisoang hangata tse thehiloeng ho cobalt. Tšobotsi ea eona e kholo ka ho fetisisa ke coefficient e tlase ea likhohlano, 'me e na le khanyetso e ntle ea ho apara, ho hanyetsa kutu le ho hanyetsa mocheso o phahameng.

Li-alloys tsa T 800 tse thehiloeng ho cobalt li entsoe ka mekhahlelo e thata ea intermetallic (Laves) e qhalakantsoeng ka mokhoa o bonolo oa eutectic kapa o tiileng oa tharollo. Li bonts'a ts'ebetso e ntle ka ho fetesisa ea ho ts'oaroa le ho ts'oaroa, khanyetso e phahameng ea kutu 'me li loketse haholo maemo a thata a ho tlotsa. Ho hanyetsa ho roala ha li-alloys tsa Tribaloy ho itšetlehile haholo ka karolo ea boholo ba karolo ea Laves.

Tribaloy T-800 e etselitsoe ho hanela ho roala ha mocheso o phahameng le ho phatloha. Ka lebaka la boholo ba eona ba chromium, e na le oxidation e ntle haholo le khanyetso ea kutu. T-800 e thata ebile e na le khanyetso e ntle ea ho roala ho feta T-400.

T-800 e bonts'a khanyetso e ntle ea kutu ka acetic acid (50% concentration, beiling) le phosphoric acid (85% concentration, 66 ° C). Ho hanyetsa ha kutu ho hotle ho boetse ho bonoa ka sulfuric acid (5% concentration, 66 ° C).

Lisebelisoa

T-800 e sebelisoa haholo indastering ea sepakapaka ka lebaka la mocheso oa eona o phahameng oa mocheso le khanyetso e matla, haholo-holo ka har'a li-blade tsa turbine tsa sefofane. Ntle le moo, e boetse e sebelisetsoa ho etsa kapa ho apesa likarolo tse fapaneng maemong a holimo le a kutu, joalo ka li-bearings, lik'hamera, mehele e bolokang, mehele ea piston ea diesel, litiiso tsa mochini, litulo tse behang, li-valve trims le likarolo tsa pompo.
