摘要: Abstract Ni-Zr composite coatings were prepared by electrodepositing with the Zr particle loadings from 0.1 g/L to 0.7 g/L Zr. Then aluminized pack cementation and heat-treatment obtain Zr-doped β-NiAl coatings. The effects of on coating microstructure oxidation performance investigated. spallation resistance for NiAl was better than without 0.5 g/L loading exhibited best duo a lower growth rate oxide scale formation mechanically interlocking pegs structure.
