Abstract

A method is proposed for determining the elastic modulus and Poisson's ratio for a protective coating in static uniaxial tension. The difference in Poisson's ratio between the substrate and the coating results in additional stresses, and the coating is in a planar state of stress. Formulas are derived for the coating's elasticity characteristics in terms of a single test on a coated specimen. That method has given the elastic modulus and Poisson's ratio for gas- plasma coatings.
