Abstract
In test research, the technology of the blades growing on the disk part of the titanium compressor wheel by heterophase laser powder metallurgy was applied. The experiments were carried out to select the optimal modes of the process, ensuring the absence of defects in the form of pores, non-melting, cracks. The influence of granulometric composition on mechanical characteristics was also investigated.The optimal modes of the additive technological process, providing the formation of a defect-free structure and optimal mechanical properties of the blanks are found as a result of the experiments. The samples of titanium powder alloy Ti6Al4V and hybrid samples consisting of cast and powder materials were produced with the help of technology mention above.Tests of the grown and hybrid samples were carried out to determine the mechanical properties. Studies of micro and macrostructure of the samples were produced. Calculations of the stress-strain state and dynamic characteristics for the initial and hybrid glare using the found mechanical properties were carried out. Preparing testing hybrid titanium wheel carries out now. This technology also can be used for repairs of blisks blades.
