Dab tsi yog rheniumtungsten pas nrig?
rhenium:
Rhenium yog tshuaj lom neeg zoo ib yam li manganese thiab yog cov khoom siv los ntawm kev rho tawm thiab ua kom zoo ntawm molybdenum thiab tooj liab ore. Rhenium qhia ntau yam oxidation xeev los ntawm -1 mus rau +7 hauv nws cov tebchaw.
Rhenium-nickel-based superalloys yog siv nyob rau hauv dav hlau cav combustion chambers, turbine hniav thiab tso nozzles.
Cov alloys muaj txog li 6% rhenium, ua rau lub dav hlau lub cav raug siv ntau tshaj plaws ntawm lub caij, nrog rau kev siv catalytic hauv kev lag luam tshuaj yog qhov tseem ceeb thib ob. ntawm. Vim tias cov khoom tsis tshua muaj txheeb ze rau qhov xav tau, rhenium yog ib qho ntawm cov hlau kim tshaj plaws, nrog tus nqi nruab nrab ntawm kwv yees li $ 4,575 ib kilogram ($ 142.30 ib troy ounce) raws li lub Yim Hli 2011; Nws kuj tseem ceeb heev Nws yog ib qho tseem ceeb ntawm kev ua tub rog tseem ceeb vim tias nws yog siv rau hauv kev ua haujlwm siab ua tub rog dav hlau thiab foob pob hluav taws cav.
