文摘
- •
Multilayer Ir coating was obtained by double glow plasma on WC substrates.
- •
Multilayer had columnar grains with some voids between grain boundaries.
- •
The coatings were ablated in carburizing and oxidizing oxyacetylene flames.
- •
The substrates were protected more effectively by multilayer than monolayer.
