Special Issue Information

Dear Colleagues,

Currently, powder materials based on metals, ceramics, and polymers are widely used in all known fields of science and technology. Various types of powders are used for the manufacture of structural elements, synthesis of new materials, and creation of functional coatings. The demand for powder materials increases every year, and the development of new technological processes requires the production of new technical and scientific solutions for the creation of powders with specified physical, chemical, and functional properties. An important development feature of new powder materials is the mandatory achievement of a combination between moderate resource consumption, technological efficiency of the production process, and ensuring proper performance of the final product.

This Special Issue focuses on the synthesis and preparation of powder materials for novel technological processes, including additive manufacturing, high-tech coating methods, and chemical synthesis. The thematic plan of the Special Issue ranges from the development of methods for creating and modifying powder materials to the application areas and preparation of various powders for specific technological processes.

In particular, the topics of interest include, but are not limited to:

  • development of new compositions and preparation of powder materials for novel manufacturing processes;
  • surface treatment and modification of powder materials;
  • development of composites based on powder materials;
  • investigation of the powders surface and core-shell composites;
  • studying the evolution of the powder surface;
  • effects of physical and chemical influences on the structure and properties of powders;
  • new applications of modified powder materials.

This work aims to study the possibility of obtaining Al–C composite from AlSi10MgCu aluminum matrix with the addition of 500 nm-sized diamond particles by selective laser melting (SLM) process. Al–C composite powder was prepared by mechanical mixing to form a uniform cover along the surface of aluminum particles. The diamond content in the resulting AlSi10MgCu-diamond composite powder was equal to 0.67 wt %. The selection of the optimal SLM parameters for the obtained composite material is presented. For materials characterization, the following methods were used: scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Raman spectroscopy. X-ray photoelectron spectroscopy (XPS) was applied after SLM printing for a detailed investigation of the obtained composites. The presence of carbon additives and the formation of aluminum carbides in the material after the SLM process were demonstrated. Full article

This work aims to study the possibility of using an electrostatic drum-type separator to prepare a powder with a narrow size distribution curve for usage in additive manufacturing. The size distributions of the uncoated commercial aluminum powders ASP-30, ASP-22, and ASP-5 were analyzed. It was shown that the powders ASP-30 and ASP-22 have similar asymmetric distributions with a SPAN of 1.480 and 1.756, respectively. ASP-5 powder, in turn, has a narrow distribution with a SPAN of 0.869. ASP-30 powder was chosen for further experiment because, traditionally, separators are used to classify large-sized materials with particle size more than 100 μm. The optimal mode of electrostatic classification was proposed for the selected powder. Various classification methods, including centrifugal and electrostatic, were compared. The powders before and after classification were studied by XRD, SEM, TEM, and TG–DSC analyses. The obtained results showed that electrostatic classification does not lead to the formation of coatings on the processed powders. Electrostatic separation effectively narrows the particle size distribution, making it a suitable and valuable method to classify initial powders for additive manufacturing. Full article
