| description | The article focuses on the possibility of manufacturing bimetallic products for specific industrial applications using laser-directed energy deposition (LDED) additive technology to replace the traditional brazing process. Preferential process regimes were determined by parametric analysis for the nickel-alloy–steel and molybdenum–steel pairs. Comparative studies of the microstructure and hardness of the deposited layers and the transition layer at the boundary of the alloyed materials have been carried out. It is shown that LDED provides better transition layer and operational properties of the final part since the low-melting copper layer is no longer needed. A combined technological process has been developed, which consists in combining the traditional method of manufacturing a workpiece through the casting and deposition of a molybdenum layer by LDED. |
