All metal products that operate under high loading conditions are subject to wear over time. Therefore, there is a need to restore the geometric shape of the working parts after the consumption of the product life. For each material from which the product is made, special repair conditions are needed. There are many defects that can appear during the repair process, for example: cold and hot cracks, delamination and cavities. This article explores the possibility of repair using the DED process of the working part of the stamp from high carbon steel grade SKD11. Restoration of the worn area was carried out by surfacing the powder die tool steel H13. The results of the study of the structure and hardness in the repair zone are presented. It is shown that the obtained values are sufficient for this type of product, which indicates the successful restoration of a worn section of a high carbon steel product using the DED method.Keywords: Additive technology, direct energy deposition, repair, powder metallurgy, automated production
