Lub combustion chamber liner yog cov thermally stressed feem ntau nyob rau hauv lub cav turbine. Oxidation flaking (scaling) yog ib qho kev sib tw loj rau kev kho, kho, thiab kho dua tshiab (MRO) cov kws tshaj lij thiab cov kws tsim lub cav.
Thaum cov txheej txheem alloys ua haujlwm ntawm qhov kub thiab txias mus txog800 degree, cov ntaub ntawv ntxeem tau oxide txheej. Thaum lub sij hawm thermal cycling sai, qhov oxide scale flakes tawm thiab diffuses downstream, paug rhiab sensors thiab ua rau txawv teb chaws khoom puas tsuaj (FOD)-zoo li yaig nyob rau hauv siab - ceev turbine hniav. Qhov no tuaj yeem ua rau lub cav tsis tau npaj tseg thiab txo lub sijhawm nruab nrab ntawm kev kho dua tshiab (MTBO).
NtawmGnee Alloy, peb tshem tawm qhov kev pheej hmoo no. Peb aerospace-qibGH3030 (sib npaug rau Nimonic 75)yog tsim tshwj xeeb los tsim cov txheej txheem tiv thaiv Cr2O3 (chromium oxide) nruj nreem, kom ntseeg tau tias koj lub zog propulsion ua haujlwm hauv xoom- ib puag ncig kev sib kis.
