Electroformed Nanocrystalline Coatings An Advanced Alternative to Hard-Chrome Electroplating

Abstract

Develop an environmentally benign advanced nanocrystalline Co-based coating technology that: Is compatible with conventional electroplating infrastructure, Will produce coatings that meet or exceed the overall performance of hard chrome (hardness, wear, fatigue, corrosion, and thermal stability). Has costs similar to or less than life-cycle cost of existing hard chrome electroplating processes. Will be applied to non-line-of-sight surfaces. Cobalt alloy selection: Mechanical properties, High plating efficiency, No constituents on EPA or AFMC lists of hazardous materials, Longer term view.
