Analysis of comprehensive investigations of divertor armor erosion under action of edge-localized modes (ELMs) using the PEGASUS-3D code has been performed. Different erosion mechanisms for tungsten (W) and carbon fiber composite (CFC) armor materials have been revealed. This difference explains almost 3 orders of magnitude difference in the erosion rates of CFC and W. Investigation of the crack pattern evolution under repetitive ELM-like surface heat load has been done. Special treatment for tungsten armor tiles has been proposed for reduction of dust production rate in ITER operation regime.
