Porous Nickel Plating as a Surface Treatment for Bonding Dissimilar Materials

Abstract

The effectiveness of porous nickel-plated films in the bonding dissimilar materials was investigated in this study. A microscopic rough surface was formed by porous nickel plating on a metal, and the plated surface was bonded with several plastics. Polyethylene, polypropylene, and polycarbonate were used as bonding plastics, and heat pressing was adopted as the bonding method. As the result of tensile test, the bonding strength was improved by depositing porous nickel-plated films on a metal. In particular, polypropylene could not bond with non-porous films but it could with porous films. The bonding strengths of polyethylene and polycarbonate were also improved with the deposition of porous nickel-plated films.
