Influence of pulse frequency on the microstructure and wear resistance of electrodeposited Ni–Al2O3 composite coatings

Nickel matrix composite coatings reinforced with sub-microsized Al2O3 particles were produced by pulse electrodeposition and the effect of pulse frequency on the microstructure, hardness and wear resistance of Ni–Al2O3 composite coatings were investigated. The results showed that the pulse frequency significantly influenced the preferred orientation of Ni–Al2O3 composite coatings; the texture of the coatings progressively changed from a strong …
