Investigation of coating substrate compounds using inclined spherical indentation

The complete analytical approach for both the elastic normal and tangential Hertzian loading of a coating substrate compound is presented in this pape r. This theory is intended to act as a tool for experimental applications. Here, the analytical model will be applied to a hard coating substrate comp ound. Its validity will be discussed with the help of finite element calcul ations of a spherical/plane stress model. In addition, experimental data ob tained for an aluminium coating on glass and measured with an UMIS 2000 ind entation system will be discussed. (C) 1999 Elsevier Science S.A. All right s reserved.
