文摘

Plasma transferred arc process was used to deposit cermet coatings.

The alloy matrix was NiCrAlY, reinforced by YSZ filler.

The cermet coatings showed a good metallurgical bonding to the substrate.

Coating microstructure revealed a dendritic growth.

Small YSZ particles were well distributed inside the alloy matrix.
