Abstract (en)

[origin: WO2016044708A1] Electrodeposited nanolaminate materials having layers comprised of nickel and/or chromium with high hardness and processes for making them are disclosed. The uniform or substantially uniform appearance, chemical resistance, and high hardness of embodiments of the nanolaminate NiCr materials described herein render them useful for a variety of purposes including wear (abrasion) resistant barrier coatings or claddings for use in decorative as well as demanding physical, structural and chemical environments.
