    Abstract

    The applicability of the Jacquet peel test for determining the adhesion of plated coatings on metallic substrates was investigated. A procedure was developed to permit testing of various plated coatings without the need for elaborate equipment, and conditions were optimized for determining the peel strength on different metallic substrates. Use of the peel test was demonstrated on a production part. The influence of some pre- or post-plating treatments on adhesion was examined using the peel test. A relationship was established between the tensile strength of the substrate and the possible maximum peel strength.
