Dual-bath Plating of Composition Modulated Alloys (CMA) based on a newly developed Computer Controlled Plating System

Composition Modulated Alloys (CMA) are attracting ever increasing interests, as new and fascinating appli-cations are reported. Until recently, producing these multilayered coatings have been difficult, particularly for larger samples. This presentation will explain the design, use and purpose of a computer controlled plating system for producing large scale CMA-coatings.

Employing a dual-bath technique, multilayered materials with more than 1000 alternating layers have been manufactured and investigated. The thickness of each layer ranges from 25 nm to several microns. The characterisation results, as obtained with SEM and applications for multilayered systems such as Cu/Ni and Cu/Co, as well as the possibilities and limitation of the plating system will be discussed.
