Embodiment Construction

[0184] The present invention relates to a laminated article comprising a layer of structured metallic material on a polymeric substrate suitable for shaping to form a precursor to the metal-clad polymeric article. The metallic material / coating is fine-grained and / or amorphous and is produced by DC or pulse electrodeposition, electroless deposition, physical vapor deposition (PVD), chemical vapor deposition (CVD) and gas condensation, etc. of. Overcoming the debonding of the coating from the substrate due to the inherent mismatch in the coefficients of thermal expansion of the metal and polymer of the metal-clad polymer articles of the present invention and through appropriate surface activation and / or Surface roughness and / or metal-polymer interface surface design increases the detachment strength between the metal material and the polymer to achieve acceptable thermal cycling performance.

Abstract

Metal-clad polymer articles containing structural fine-grained and / or amorphous metallic coatings / layers optionally containing solid particulates dispersed therein, are disclosed. The fine-grained and / or amorphous metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling although the coefficient of linear thermal expansion (CLTE) of the metallic layer and the substrate are mismatched. The interface between the metallic layer and the polymer is suitably pretreated to withstand thermal cycling without failure.

Description

[0001] Cross-Referenced Related Applications [0002] This application is a continuation-in-part of Serial No. 12 / 476455 filed June 2,2009. field of invention [0003] The present invention relates to a metal clad polymeric article comprising a polymeric material having a coefficient of linear thermal expansion in at least one direction exceeding 25x10 -6 K -1 , and fine-grained (average particle size: 2-5000nm) or amorphous metal material, the metal material has less than 25x10 -6 K -1 The coefficient of thermal expansion can enhance the detachment strength between the metal material and the polymer. The metal-clad polymer articles with mismatched coefficients of thermal expansion exhibit good adhesion between the metal layer and the polymer material and excellent thermal cycling performance, and are suitable for structural applications. Background of the invention [0004] The present invention relates to metal-clad polymer articles comprising an amorphous or fine-gr...
