摘要
This paper investigates the effect of nanostructured and micrometre size YSZ powder coated plasma spray coating on high temperature oxidation resistance of Inconel (IN 718) substrate. The oxidation rate and reaction kinetics are studied, and the post-corroded scales are characterised in SEM, field emission SEM and X-ray diffraction. The results clearly indicate that there is an improvement of oxidation resistance in the case of nanostructured YSZ coating as compared to the micrometre size YSZ coated specimen. The detail mechanism of the significant improvement of the oxidation resistance of nanostructured coating is discussed in this paper.
