Abstract:
Optimized plating deposition parameters were obtained using a Design of Experiment DOE approach. These parameters were validated through supplemental testing and found to be non-embrittling with improved fatigue and neutral salt fog corrosion performance as compared to hard chromium electroplate. The nCoP deposit did exhibit reduced hardness 560 VHN and reduced taber wear abrasion performance as compared to hard chromium electroplate. Producibility evaluations were performed utilizing a J52 Shaft section and a J52 Coupling component. Optimized plating parameters were successfully demonstrated on both ID OD areas. The above plated components were then finished machined at FRC-SE with no observable defects.
