This paper is intended to show the benefits of instrumented indentation for advanced testing of highly heterogeneous materials such as thermal spray coatings. These materials possess a particular microstructure composed of splats, unmelted particles, cracks and voids. Due to this structure, their mechanical properties are known to be load dependent. This paper presents a thorough study of this subject on two representative types of thermal spray coatings: Al2O3 ceramics and 316 L stainless steel, both sprayed by water stabilized plasma system. The instrumented indentation, offering a broad range of loading forces, was chosen for characterization of these coatings at various scales: from the smallest structural units up to the coating as a whole.
