英文摘要	Oxidation behavior of magnetron sputtered Cr-Al-Si-N coatings on zirconium-alloy coupons was studied in 1200 degrees C steam up to 8 h, revealing the microstructural evolution and the oxidation resistance by electron microscopy. A similar to 310 mu m thick Zr-O layer formed on the uncoated coupon after the 6 h oxidation, whereas the coated coupon retained almost unoxidized, due to a homogenous and stable bilayer scale of Cr2O3/alpha-Al2O3 on the surface. It was assumed that the column-free structure and isotropic nanostructure of coatings could favor a timely and in situ formation of the bilayer scale, followed by long-term maintenance of its integrity.
