High temperature corrosion behaviour of a gradient NiCoCrAlYSi coating II: Oxidation and hot corrosion

The high temperature oxidation and hot corrosion behaviour of a NiCoCrAlYSi coating and a gradient coating were investigated. The gradient coating showed better performance of re-healing alumina scale due to its possession of more ? phase as Al reservoir.

Isothermal oxidation behaviour of a gradient NiCoCrAlSiY coating deposited by arc ion plating on a Ni-based single crystal superalloy

gradient NiCoCrAlSiY coating consisting of Al-enriched outer zone and Cr-enriched internal zone was prepared using arc ion plating method and subsequent annealing treatment. Isothermal oxidations were performed at 1000?C and 1100?C in static air.
