2）、四方相氧化鋯（t-ZrO2）和t-Zr0.82Ce0.18O2組成。隨鈰濃度的增加，膜層厚度逐漸增加。當(dāng)鈰濃度為9mol%時(shí)，陶瓷膜厚度為135.5 μm，結(jié)合力為52.46 N，膜層具有優(yōu)異的阻氫性能，阻氫滲透因子為19。鈰的加入抑制了t-ZrO2向m-ZrO2的相轉(zhuǎn)變，促進(jìn)了高溫穩(wěn)定t-ZrO2的生成。;The ceria-stabilized zirconia (CSZ) coating with an excellent hydrogen resistance performance was prepared by micro-arc oxidation (MAO) with cerium addition. The thickness, bonding strength, morphology, phase structure, chemical valence, and hydrogen resistance of ceramic coatings were investigated by coating thickness gauge, auto-scratch tester, scanning electron microscopy, energy dispersive X-ray spectrometer, X-ray diffraction, and X-ray photoelectron spectroscopy, and vacuum dehydrogenation experiment. Results show that CSZ ceramic coatings are mainly composed of monoclinic zirconia (m-ZrO2), tetragonal zirconia (t-ZrO2), and t-Zr0.82Ce0.18O2. With increasing the cerium content, the thickness of coating is increased. When the cerium content is 9mol%, the thickness of CSZ ceramic coating reaches the maximum of 135.5 μm, the bonding force is 52.46 N, and the hydrogen permeation reduction factor (PRF) is 19, which indicates an excellent hydrogen resistance. The cerium addition inhibits the phase transformation from t-ZrO2 to m-ZrO2, thereby promoting the formation of stable t-ZrO2 at elevated temperatures."/>
