Specific Features of Structure Formation in the Course of Modification of the Coatings on Products Made of Dispersion-Hardened Steels

We analyze the technology of hardening and restoration of products made of dispersion-hardened steels and steels containing large amounts of nonmetallic inclusions. For the formation of coatings, we used secondary raw materials obtained as a result of the utilization of a certain collection of ammunition, including nano- and dispersed diamonds. We also study the influence of parameters of the technology of detonation charge modification in the process of surfacing on the metal structure of the restored product. The best results were obtained as a result of introduction of 5.0–7.0% of charge (relative to the mass of the electrode). This guarantees the formation of a homogeneous structure with grains of similar sizes in the coating and increases the wear resistance of the restored product by 25% and of the mating product by up to 37%.
