Special Issue Information

Dear Colleagues,

This Special Issue, “Innovative technologies for designing, obtaining and testing modern engineering materials used in industry”, is a forum for the publication of articles allowing an in-depth understanding of the relationship between the structure, properties in hybrid materials and advanced composites, engineered polymers, and low-density/high-strength metals or alloys, as well as applying advanced technologies often used in industry for designing and obtaining these innovative engineering materials. A significant contribution in the field of material engineering is related to the development of new material solutions in the area of testing the quality of the treated surfaces and the internal structure of the material subjected to different processing with the use of materialographic methods of material testing, investigating the quality of cut edges and heat-affected zones with the use of materialographic test methods, developing guidelines for the technological assumptions of different processing (for example, laser processing). Undertaking an innovative scope of research covering a range of parameters influencing the technological process will allow for the use of various research techniques and the presentation of the results in a global scientific forum. Industrial companies, based on their own experience (know-how), knowledge, and research results, will contribute innovative technological aspects to the development of the discipline of materials engineering, which will also be verified by global scientific communities as part of the project's research. It is important that scientific research corresponds to the expectations of the industry, and the implementation of this Special Issue will help with this.

The included studies will be in line with the current directions of research conducted by scientific institutes and laboratories of mass producers.

The main topics of interest include, but are not limited to, the following:

  • The characterization techniques for the innovative surface layers and coatings;
  • Designing selected functional layers in the engineering of photovoltaic cells;
  • Designing selected functional layers in the technological processes of producing semiconductor heterostructures;
  • Study and producing thin layers of metal oxides using, e.g., laser techniques;
  • Characterization of innovative materials to produce welding joints and surface layers;
  • The study of the structure and mechanical properties of welding joints and surface layers;
  • The study of modern surfacing and technologies to produce surface layers and coatings;
  • The study of improved economics of material engineering;
  • Advanced methods of investigating the structure and properties of engineering materials.

The microstructure of the in situ TiC-reinforced composite surface layers developed during laser surface alloying of a ductile cast iron substrate with titanium was related to the solidification conditions in the molten pool. The solidification conditions were estimated using infrared thermography. It was found that the cooling rates of the melt up to about 700 °C/s enable the complete reaction between carbon and the entire amount of titanium introduced into the molten pool. In turn, the cooling rate of about 280 °C/s for the melt containing 8.0 wt% Ti allows the TiC particles to grow in the dendritic form with well-developed secondary arms and a total size of up to 30 µm. For a constant Ti content, the cooling rate of the melt had no effect on the TiC fraction. The increase in the cooling rate elevated the retained austenite fraction in the matrix material, lowering its hardness. Full article

Proton-exchange membrane fuel cells are one of the most promising energy conversion technologies for both automotive and stationary applications. Scientists are testing a number of solutions to increase the durability of cells, especially catalysts, which are the most expensive component. These solutions include, among others, the modification of the composition and morphology of supported nanoparticles, the platinum–support interface, and the support itself. A detailed understanding of the mechanism of platinum degradation and the subsequent improvement of the durability of the entire cell requires the development of methods for effectively monitoring the behavior of catalytic nanoparticles under various cell operating conditions. The Identical-Location Transmission Electron Microscopy (IL-TEM) method makes it possible to visually track structural and morphological changes in the catalyst directly. Because the tests are performed with a liquid electrolyte imitating a membrane, they provide better control of the degradation conditions and, consequently, facilitate the understanding of nanoparticle degradation processes in various operating conditions. This review is primarily intended to disseminate knowledge about this technique to scientists using electron microscopy in the study of energy materials and to draw attention to issues related to the characterization of the structure of carbon supports.
