This work presents results in the field of synthesis of new metal matrix composites with matrix NiTi and particles TiB 2 , and their use as additives to fabricate metal matrix composites based on the Inconel 625 alloy. NiTi-TB 2 powders were obtained using self-propagating high-temperature synthesis. Composite NiTi-TiB 2 particles were spheroidized on a high-frequency induction plasmatron. Composite NiTi-TB 2 particles were mixed with metallic Inconel 625 powder with particle sizes of 50-150 µm. We used direct laser deposition by means of mixture of powders to grow samples with different contents of ceramics in the metal matrix. The process of direct laser deposition during the experiment was investigated. We have determined the peculiarities of the formation of the structure in metal matrix composites with different contents of titanium diboride. We have demonstrated the possibility of using Direct Laser Deposition (DLD) for fabricating items from ceramic metal materials. We have determined promising fields of further research for the purpose of obtaining efficient metal matrix composites using additive manufacturing technologies.

“…The main trend in the development of additive technology is to increase productivity while maintaining the required quality of the product. The most promising technology of product manufacturing is direct laser deposition analogue direct metal deposition (DMD), when the product is formed from a powder, which is supplied by compressed gas-powder jet directly into the laser action zone [8][9][10][11]. The jet can be as coaxial and as non-coaxial to focused laser beam, which provides heating and partial melting of the powder and heating the substrate.…”

Presently the additive technologies in manufacturing are widely developed in all industrialized countries. Replacing the traditional technology of casting and machining with additive technologies, one can significantly reduce material consumption and labor costs. They also allow obtaining products with desired properties. The most promising for manufacturing large-sized products is the additive technology of high-speed direct laser deposition. Using this technology allows to create complex parts and construction to one technological operation without using addition equipment and tools. This technology allows decreasing of consumption of raw materials and decrease amount of waste. Equipment for realization of DLD technology is universal and based on module design principle. DLD is based on layer-by-layer deposition and melting of powder by laser beam from using a sliced 3D computer-aided design (CAD) file. The materials used are powders based on Fe, Ni, and Ti. This chapter presents the results of machine design and research HS DLD technology from various materials.

StreszczenieTechnologia ultraszybkiego napawania laserowego stanowi rozwinięcie metod deponowania powłok funkcjonalnych przy użyciu wiązki lasera. Charakteryzuje się ona wysokimi prędkościami procesu, pozwalając uzyskiwać znaczne szybkości chłodzenia oraz niewielkie wymieszanie z podłożem, co prowadzi do dużej czystości materiału powłoki i lepszych własności nałożonej warstwy w porównaniu z konwencjonalnym napawaniem laserowym. W niniejszym artykule przedstawiono technologię ultraszybkiego napawania laserowego w aplikacji dla przemysłu lotniczego. Zaprezentowano opracowane stanowisko do realizacji procesu oraz weryfikację technologii na komponencie podwozia samolotu, modyfikowanym w ramach projektu AMpHOra. Uzyskane rezultaty wskazują, że otrzymane tą technologią powłoki mogą stanowić alternatywę względem powłok elektrolitycznych z twardego chromu. Słowa kluczowe: napawanie laserowe; powłoki funkcjonalne; lotnictwo AbstractUltra-High-Speed Laser Cladding technology is one of the developments of functional coating deposition methods with usage of laser beam. It is characterized by high cladding velocities, allowing to obtain a significant cooling rates and low dilution, which leads to high purity of the clad and thus increase of properties of the deposited coating in comparison with the conventional laser cladding. In this paper a technology of Ultra-High-Speed Laser Cladding has been shown in case of applications for the aviation industry. The developed setup for the process has been presented and verification of the technology on the airplane chassis component for AMpHOra project has been discussed. The obtained results shown indicate that the coating received via this technology may compete with hard chrome plating.
