The method of selective laser melting (further SLM) has big prospects from the point of view of achievement of a difficult form of details with high precision and quality of a surface, however SLM has also a number of technological restrictions from the point of view of achievement of a difficult form of details. In this work technological capabilities of production of figurine details from a heat resisting cobalt alloy are investigated by method of selective laser melting, technological restrictions of a method and way of their overcoming are shown.

The article touches upon the technical problems and perspectives of implementing the Selective Laser Melting method for producing structural components for aircraft. The possibilities of additive manufacturing technology processes and their advantages in comparison with traditional methods of part formation are shown. Issues of standardization in the field of additive manufacturing, as well as terms and definitions adopted at the present time, are considered. Based on the analysis of literary sources, the necessity of developing selective laser melting methods for the specific steels and alloys used in aircraft production is shown.

The aim of the present work is to investigate features of low-density materials' structure formation during laser microcladding. Clad tracks with the submillimeter width were successfully produced by laser microcladding of the low-density Al–Si hypereutectic alloys. Microstructures produced with various process parameters and with various chemical compositions of the cladding material were investigated. Structure formation mechanism of Al–Si alloys during laser microcladding was discussed. The influence of laser microcladding on the solidification process and on the final solidification microstructure was studied. The influence of structure formation mechanism on the mechanical properties of the solidified material was investigated. The clad walls less than 300 μm wide with aspect ratio of the long and short sides about 7.5 were manufactured. Structure changes that occurred during the placement of many layers on top of each other were discussed. Mechanical properties and surface roughness of the clad walls as well were investigated. Possibility of using the laser microcladding technique to produce a volume in the submillimeter range was demonstrated.

In this article, we give a preferential regime of selective laser melting for the production of parts from a cobalt superalloy using a PTK-PS domestic machine, which can find application upon the production of components from various superalloys in the aviation and atomic industry and in the automobile industry. We have investigated the phase composition and determined the physicomechanical properties of the samples prepared under the preferential regime of selective laser melting. It has been established that the structure of the alloy obtained by selective laser melting consists of two supersaturated solid solutions based on the low-temperature hexagonal and high-temperature cubic cobalt modifications, which leads to an increase in the strength characteristics of the samples in comparison with the cast samples.
