The aspects of terminology, definitions and classification in the technology of additive production are considered. The principal possibility of fabrication of complex-shape parts from a refractory cobalt alloy by the method of selective laser melting and deposition of hard and wear-resistant coatings from Ti and SiC powders by coaxial laser surfacing is shown. The technological possibility of microlaser surfacing with lateral resolution about 100 mm in the production of parts from aluminum alloys is considered. The mechanisms of formation of structure in the studied alloys typical for selective laser melting, laser surfacing and microlaser surfacing are determined. The physical and mechanical properties of the alloys are investigated.

Aregression model for simulating shape forming of a roll under laser surfacing (LS) of aluminum-base alloys

is developed. The effect of the LS parameters on the geometrical characteristics of the surfaced rolls and on

the structure of the coating is studied. A“Laser Online” software is created in the form of an automated system

for development of recommendations for LS of aluminum alloys. The parameters determined for LS of alloy

AlSi30 provide a fine quasi-eutectic structure raising the level of the microhardness distributed uniformly

over cross section.

This paper reports the results of studies of the fretting wear resistance of specimens manufactured by laser microcladding. The materials of specimens are powders of Al-Si hypereutectic alloy which contains: (70-74)wt.% Al (26-30)wt.% Si. %. The influence of the laser cladding parameters on hardness and fretting wear resistance of the claded materials was investigated. It was found that hardness and wear resistance of the cladded material increased with the decrease of powder mass flow.

This work considers the possibilities of using static analysis and scanning electron microscopy techniques to determine the properties of disperse materials, i.e. corrosion resistant steel grades 12H18N9T (AISI 321) and 20H13 (AISI 420), taken into account in the selective laser melting technique.

The possibility of manufacturing of such geometrically complex parts as nozzles via the selective laser melting of heat-resistant cobalt alloy is demonstrated. The mechanisms responsible for forming the structure of investigated alloys under the conditions of selective laser melting are characterized. The physicomechanical properties of the resulting parts are determined.
