ARTICLE WITH A LAYER COMPOSITE

摘要

An object with a stratified composite material comprises a first non-metalli c layer and a second metallic layer applied to the first non-metallic layer which contains at least one polymer. The boundary layer between the non- metallic layer and the metallic layer has a roughness with an Ra value of maximum 5 .mu.m, an adherence of at least 12 N/mm2 and a standard adherence deviation of maximum 25 % of the mean arithmetic value, distributed over the surface of the composite material as six different measurement values. Also disclosed is a method for producing said object and its use.
