Ablation Property of the Plasma Sprayed NiCrAlY-ZrO₂Compound Coating on Stainless Steel Material

Abstract:

The NiCrAlY-ZrO₂ anti-ablation compound coating was prepared on one surface of a 201stainless steel by plasma spraying, and the ablation property was studied by the cyclic ablation experiment. The morphology and XRD pattern of the NiCrAlY-ZrO₂ coating were characterized by SEM and XRD methods before and after ablation on the high-temperature oxyacetylene flame. The results show a good adhesion between the coating and substrate. After the ablation at high temperature flame, the smoothness of the coating surface declined. The coating, under the oxyacetylene flame of 2800°C, can effectively improve the anti-ablation property of the substrate material, the mass loss for the coated sample is 1/4 of the uncoated specimen under the same number of ablation cycles.
