In the coating, the nodular defect was observed to worsen severely the properties. For testing under oxidation condition, the nodular defect results in the internal oxidation of Al. No single Al oxide scale may be formed at 1100℃ owing to consumption of Al. Under hot corrosion, it becomes as short-path for diffusion of S through the coating, thus sulphuring the coating together with the substrate. During thermal shock testing, it may act as the source of cracking, and moreover, if cyclic stress applied, the cracks propagate toward the substrate, the thermal fatigue properties of coating will be worsened.
