This article is devoted to Inconel 718 heat-resistant nickel alloy. Comparison of samples obtained by high-speed direct laser deposition technology of powders from different manufacturers on their structure and properties was carried out. The dependence of the influence of the chemical composition of the powders on the formation of defects in the studied samples was established

The additive technology of direct laser deposition (DLD) belongs to the class of 3D printing methods for metal parts and constructions. It is promising for the manufacture of large-sized complex parts for the aviation and shipbuilding industries. Methods of additive production dictate serious requirements for the properties of building powders, but with the right choice of system and taking into account all the processes that occur when a selected source acts on powder materials, unique individual material properties can be achieved. In this work, the influence of powder quality, protect atmosphere as well as processing parameters on the structure and properties of deposited parts manufactured Ti-6Al-4V investigated. Аддитивная технология прямого лазерного выращивания (ПЛВ) относится к классу методов 3D печати металлических изделий. Она является перспективной для изготовления крупногабаритных сложнопрофильных изделий авиационной и судостроительной промышленностей. Методы аддитивного производства диктуют серьезные требования к свойствам используемых порошков, но при правильном выборе системы и с учетом всех процессов, протекающих при воздействии выбранного источника на порошковые материалы можно добиться уникальных индивидуальных свойств материала. В данной работе представлены результаты исследований влияния качества порошков, качества атмосферы и технологических режимов процесса на структуру и свойства конечных изделий, изготовленных методом прямого лазерного выращивания из титанового сплава ВТ6. Кроме того, показана принципиальная возможность повторного использования титановых порошков для достижение более высоких экономических показателей процесса.

This article presents the technology of direct laser deposition. This technology is one of the most perspective new technologies. It allows realizing heterophase process during the manufacturing, in which the process of partial melting of the used powder is realized. The product is formed from a metal powder, which is supplied by a compressed gas-powder jet directly into the laser action zone. Ti-based alloys are interesting for many industrial areas, for example, engine systems, aircraft and shipbuilding, because of their corrosion resistance, low density and high strength. The influence of roughness on the mechanical properties of Ti-based products prepared by direct laser deposition was studied. It was found that the surface roughness distorts the values of the mechanical characteristics.
