Notes:
Films were prepared on the steel (Q235) by means of vacuum vapor deposition throughAl65Cu20Fe15 quasicrystal powders. Influence of ceria on the microstructure and properties of filmswere studied. TEM, SEM and XRD were used to observe the microstructure and morphology offilms. The hardness and the modulus of the film were tested by MTS. The results showed that thefilms were formed through directly vapor deposited by Al65Cu20Fe15 quasicrystal. The films wereconstituted of many phases such as CuAl2, AlCu3 and I (Al65Cu20Fe15) phase. The composition offilms was decided by the technology of deposition. After adding cerium, the microstructure of filmsdid not radically change, however the hardness and modulus of films varied with the increase ofcerium. When the cerium content was 5 wt%, the hardness of films was more than 9.0 GPa.Furthermore, adding cerium could improve obviously the corrosion resistance of films
