Performance of Anti-erosion and Anti-oxidation of high Al Steels at 1373K
The effect of Al content on the anti-erosion and anti-oxidation performance of high Al steels at 1373K is studied in this paper.By 168-hour heat treating at 1373 K and at oxidation atmosphere,These results show that for comparing non-Al steel and low-Al (wAl=1.14%) steel sample there are a more obvious and easily-dropping oxidation layer in surface in 24 h,the average oxidation rate is up to 0.406 mg/(cm2.h),but for high Al steel,there is a thinner gray oxidation layer in surface and a more fast oxidation rate for wAl<5% sample,and there is a thin,close and yellow gloss film and the average oxidation rate is only 0.016 mg/(cm2.h) for wAl=8.46% sample.The average erosion rate is 0.096 mg/cm2.h in initial 24 h and thereafter the erosion is very slow.But there is a higher erosion rate and the average erosion rate is 0.594 mg/(cm2.h) in 6 % HCl solution for high Al steel sample and comparing non-Ai steel.Accordingly high Al steel possesses a good performance of high temperature anti-oxidation and anti-erosion in NaCl solution.
