The use of nano-laminated metallic coatings is an emerging technology that is generating products with material property combinations heretofore not possible. Through a patented electrochemical controlled deposition process, precisely defined configurations of layered metal alloys can be applied to a variety of substrates or as near net shapes. The deposition process can be controlled to produce nano-scale layers with unique interfacial properties resulting in corrosion resistance, elastic modulus, strength, hardness, and fracture toughness combinations uniquely different from conventional material processing. This paper will describe the patented process, characterize the as-deposited material, explore the application of nano-laminated nickel based alloys for downhole service environments and evaluate the potential of this coating to improve corrosion resistance, extended service life and improved safety/integrity of pump, valve and tubular assets.1
