The Materials Science of Coatings and Substrates


  • Jack W. Dini, Lawrence Livermore National Labs, USA

Electrodeposition allows the "tailoring" of surface properties of a bulk material or, in the case of electroforming, the entire part. Deposits can be produced to meet a variety of designer demands. For this reason and for the possibilities that exist in terms of "new materials" for a variety of applications, a thorough understanding of the materials science of electrodeposition is of utmost importance. This book provides that understanding.
