Nyob rau hauv cov txheej txheem ntawm hluav taws xob rhaub lub caij tsim cov txheej txheem, peb siv 2 hom kev tiv thaiv cua sov hlau - hlau chromium aluminium thiab npib tsib xee chromium alloy hlau.
Lub ntsiab zoo thiab qhov tsis zoo ntawmhlau chrome aluminium cua sov hlau:
Qhov zoo:Hlau chromium aluminium cua sov hlaunws qhov kev pabcuam siab kub, qhov kev pabcuam siab tshaj plaws tuaj yeem ncav cuag 1400 degrees, (0Cr21A16Nb, 0Cr27A17Mo2, thiab lwm yam), lub neej ua haujlwm ntev, siab load, zoo oxidation kuj, siab resistivity, pheej yig tus nqi , lwm.
Disadvantages: siab kub lub zog yog tsawg, nrog rau kev siv ntawm kub nce nws cov yas nce, Cheebtsam yooj yim deformation, tsis yooj yim rau khoov thiab kho, ntau nkig, yog li nyob rau hauv lub seismic ua hauj lwm ib puag ncig ntawm hlau chromium aluminium yooj yim tawg.
Lub ntsiab zoo thiab qhov tsis zoo ntawm nickel-chromium cua sov hlau:
Qhov zoo: siab kub lub zog yog siab dua hlau, chromium thiab txhuas, nws tsis yooj yim rau deformation nyob rau hauv high kub siv, nws cov qauv tsis yooj yim los hloov, zoo plasticity, yooj yim kho, nws cov hluav taws xob siab, tsis muaj hlau nplaum, muaj zog. corrosion kuj, kev pab lub neej ntev thiab lwm yam.
Qhov tsis zoo: vim yog siv cov khoom siv tsis tshua muaj nickel hlau, tus nqi ntawm cov koob no yog ob peb zaug siab dua li ntawm cov hlau chromium aluminium, qhov kev siv kub yog qis dua hlau chromium aluminium.
