“…There is a demand for reference books that list the properties of the materials obtained using AM. There are many research papers that include data on the properties of materials that are obtained using additive manufacturing technologies on base metal substrates and ceramic substrates [9][10][11][12][13][14][15]. The wide assortment of metal powder materials used in AM continues to expand.…”

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.

“…This geometry limitation due to the fabrication process was a topic of interest for years. The most promising technique to mitigate and alleviate this challenge is additive manufacturing (AM) [8,9]. The implementation of additive manufacturing for the fabrication of ceramic composite structures will eliminate the geometry limitations from conventional fabrication methods.…”

This paper presents a physical and mathematical model that has been developed in the framework of the approach used in the computational mechanics of materials. The model is designed to enable the study of the patterns of deformation and fracture of ceramic composites with a transformation-hardened matrix that are obtained by additive technologies at the mesoscopic and macroscopic levels under intense dynamic loading. The influence of the loading rate on the formation of the fracture and energy dissipation fronts for composite materials, based on the Al2O3 20%ZrO2 system, is shown. Nonlinear effects under intense dynamic loading in the considered composites are associated with the processes of self-organization of structural fragments at the mesoscopic level, as well as the occurrence of martensitic phase transformations in matrix volumes adjacent to the strengthening particles.

“…The other reason is the relatively low cost of materials for the production of a profile tool for EDM. The design of constructive and technological features of the product allows the withdrawal of the application of superhard materials such as nanoceramics based on ZrO 2 and Al 2 O 3 on a new production level [45][46][47][48]. It contributes to their spread in the industry for creating a new class of wear-resistant parts, which are capable of operating under extreme operating loads without losing their performance.…”

On Electrical Discharge Machining of Non-Conductive Ceramics: A Review

et al. 2019

The inability of ceramic and nanoceramic processing without expensive diamond tools and with a high-material-removal rate hampers the scope of its potential applications and does not allow humanity to make a full shift to the sixth technological paradigm associated with Kuhn scientific revolutions and Kondratieff's waves and restrains the growth of the economy. The authors completed a review on the research state of ceramic and nanoceramic processing by electrical discharge machining, which is possibly solved by two principal approaches associated with the usage of standard commercially available machine tools. The first approach is related to the introduction of expensive secondary phase; the second approach proposes initiate processing by adding auxiliary electrodes in the form of coating, suspension, aerosol, or 3D-printed layer based on the components of silver, copper, or graphite in combination with an improved dielectric oil environment by introducing graphite or carbon nanoparticles, which is hugely relevant today.Technologies 2019, 7, 55 2 of 16 of cutting tools limits the resulting geometry of the product. Other machining methods such as vibroacoustic machining, laser and electron beam scribing, selective laser sintering with a binder, find their specific place in the processing of ceramics. However, they do not allow the receiving of all geometrically possible shapes of the product without losses on the operational parameters of ceramics [16][17][18].One of the most popular methods for the production of parts, regardless of their hardness, is electrical discharge machining (EDM). However, it requires the material to be conductive [19][20][21]. The process of electrical erosion of the material consists of initiating electric pulses in the interelectrode gap, in the breakdown of the dielectric medium in the gap, in establishing a discharge channel, where the temperature reaches more than 10,000 • C (low-temperature plasma). Due to such temperatures, the material is ablated, the drops of cooled material as eroded debris are washed away by the flow of the dielectric medium, and the electrodes again approach to resume the cycle. Thus, a unique crater-like topology on the surface of the workpiece is created [22][23][24][25].The inability of ceramics and nanoceramics to conduct current hampers the scope of its potential applications and restrains the growth of the progress and the switch to the next technological paradigm that most of the scientists associate with the term "nano" [26][27][28][29][30][31][32].Thus, it can be concluded that the study and development of a method for electrical discharge machining of non-conductive ceramics and nanoceramics are incredibly relevant today.The authors propose to apply the dialectical approach of cognition as a scientific approach to solve the formulated scientific problem. The dialectical approach includes the systematization and updating of existing knowledge and new data about the object of research.
