Investigation of coating substrate compounds using inclined spherical indentation

摘要

The complete analytical approach for both the elastic normal and tangential Hertzian loading of a coating substrate compound is presented in this paper. This theory is intended to act as a tool for experimental applications. Here, the analytical model will be applied to a hard coating substrate compound. Its validity will be discussed with the help of finite element calculations of a spherical/plane stress model. In addition, experimental data obtained for an aluminium coating on glass and measured with an UMIS 2000 indentation system will be discussed.
