Wear and mechanical properties evaluation

This report includes the experimental work and results obtained in the Task 4.1 regarding to the external wall investigation of the structural material and its interaction with the particles. The laboratory investigations, wear and creep tests and aim to understand the degradation mechanisms of these materials, in order to assess their performance. The main degradation expected is related to oxidation and corrosion protection, mechanical properties and wear. These properties have been studied with the State Of The Art (SOTA) materials and particles, used as reference, and the new particles developed in WP2 and the new bulk materials and coating developed in WP3. The laboratory tests are carried out under conditions simulating actual plant conditions. The degradation mechanisms of the materials are analysed in order to predict the lifetimes of the materials (heat carrier particles and heat exchanger components).The deliverable D 4.2 provides a comprehensive overview of the wear and mechanical properties testing results.
