Abstract

Platinum films of thickness 0.5 - 1.2 - 3.0 μm, deposited by magnetron sputtering onto glass and silicon, were investigated using ultra-microindentation. The tests were done with a pointed (Berkovich) indenter. The values of the hardness and elastic modulus of the composite “film + substrate” and the substrates alone were obtained for various loads and depths of penetration, and used to evaluate the hardness and elastic modulus of the films. The use of various film thicknesses and substrates has enabled us to investigate in more detail the influence of the contact radius/contact depth compared to the film thickness as well as the substrate properties on the total indentation behaviour. Various approaches to the data evaluation are discussed in the paper.
