Kev siv ntau yam ntawm Niobium: Los ntawm Hlau mus rau Aerospace (2)

Daim ntawv thov hauv Jet Engines thiab Gas Turbines

Niobium-enhanced superalloys yog qhov tseem ceeb rau ob lub dav hlau cav thiab roj turbines:

Jet Engines: Lub tshuab dav hlau ua haujlwm ntawm qhov kub siab heev vim muaj cua sov los ntawm combustion. Niobium pab cov superalloys siv hauv cov cav no muaj zog thiab tiv thaiv kev puas tsuaj thaum tshav kub kub. Qhov no yog ib qho tseem ceeb rau cov khoom xws li turbine blades thiab nozzles, uas yuav tsum ua siab ntev rau cov kev mob hnyav thiab tswj kev ua haujlwm thaum lub sijhawm ya davhlau.

Gas Turbines: Cov roj turbines siv hauv lub zog tsim hluav taws xob kuj ntsib qhov kub thiab txias. Niobium nyob rau hauv cov superalloys siv rau turbine hniav thiab lwm yam khoom ua kom lawv muaj peev xwm tuav tau cua sov thiab siab zoo. Qhov no pab txhim kho lub turbine efficiency thiab ncua nws lub neej.

Zuag qhia tag nrho, niobium lub luag hauj lwm nyob rau hauv cov superalloys no ua rau lawv zoo dua haum rau high-temperature daim ntaub ntawv, ua rau ntau npaum thiab check engine thiab turbines.
