摘要

The possibility of using the heredity effect under arc deposition and its influence on the structure and properties of multilayer tool steel-type metal was investigated. Deposition was carried out using flux-cored wires (FCWs) with varying preparation methods and compositions of charge materials, calculated to achieve the same chemical composition in the deposited metal. The charge materials in the experimental FCW included granulated metal powder PG-R6M5 in three particle size ranges: 50–100, 200–250, and 50–300 μm. The ferroalloy powders with a particle size of 50–300 μm were used in the reference FCW. The replacing of ferroalloys with chemically purer and physically more homogeneous granulated metal powders improves the welding-technological properties of flux-cored wires, stabilizes the deposition process, and enhances the structure of the deposited metal. The best results were achieved using metal powder with a particle size of 50–100 μm.
