Special Issue Information

Dear Colleagues,

Metal and polymer composite materials have unique properties. The matrix type, reinforcing phase, as well as the method of manufacturing can significantly affect the final properties of material. Reinforcing materials and coatings using micro- and nanoparticles as well as modern casting methods with controlled crystallization processes, additive manufacturing, and laser processing can be widely used in industrial applications. During all these processes, interesting phenomena of crystal growth as well as the formation of new, previously unobtained microstructures can be observed. The mechanical and physicochemical properties obtained by these innovative processes are also important.

We invite researchers to contribute to this Special Issue on “Advances in Composite Materials and Composite Coatings”, which is intended to serve as a unique multidisciplinary forum focused on the production, properties, and application of composite materials and composite coatings. The potential topics include but are not limited to:

  • Additive manufacturing;
  • Metal and polymer nanomaterials and composite nanomaterials;
  • Production and properties of cast composite materials;
  • Production and properties of composite coatings;
  • Laser processing and laser manufacturing of composite materials and coatings;
  • Testing the properties of composite materials and composite coatings;
  • Crystal growth analysis in modern composites and composite coatings;
  • Microstructure and phase analysis of composite materials and composite coatings.

The α-decay of incorporated actinides continuously produces helium, resulting in helium accumulation and causing security concerns for nuclear waste forms. The helium mobility is a key issue affecting the accumulation and kinetics of helium. The energy barriers and migration pathways of helium in a potential high-level nuclear waste forms, La2Zr2O7 pyrochlore, have been investigated in this work using the climbing image nudged elastic band method with density functional theory. The minimum energy pathway for helium to migrate in La2Zr2O7 is identified as via La–La interstitial sites with a barrier of 0.46 eV. This work may offer a theoretical foundation for further prospective studies of nuclear waste forms. Full article

Investigations on comb crack resistance of milling inserts coated with chemical vapor deposition (CVD) Ti(C,N)/α-Al2O3 and Zr(C,N)/α-Al2O3 showed a distinct wear evolution in both systems. Wear studies revealed that the appearance of comb cracks is connected to the initial CVD cooling crack network. Micropillar compression tests indicated a brittle intergranular fracture mechanism for the Ti(C,N) layer and a transgranular fracture accompanied with signs of plastic deformation for the Zr(C,N) coating. Additionally, for the Zr(C,N) based system, a compressive stress condition in the temperature range of interest (200–600 °C) was determined by in-situ synchrotron X-ray diffraction. The set of residual compressive stresses together with the ability of the Zr(C,N) layer to deform plastically are key features that explain the enhanced resistance to comb crack wear of the Zr(C,N) based system in milling of cast iron.

In microelectronic mechanical systems applications, sputtered aluminum thin films may have large roughness, which promotes the optical degradation and electromigration. This challenge motivated the present research, where magnetron sputtering equipped by radio frequency allowed for preparing aluminum and aluminum-boron thin films. This study evaluated the effect of the sputtering power and the substrate type (silicon wafer and glass slides) on the deposited films. The film’s morphology and structure were characterized via an atomic force microscope and X-ray diffraction. Pure aluminum films’ topographic findings revealed a 25.23 nm average roughness with larger grain size and hillock formation. Conversely, the aluminum-boron films possessed a 3.41 nm average roughness, with smaller grains and hillocks suppression when higher sputtering power was used. The pure aluminum films’ structural analysis uncovered a material with low crystallinity, with (111) and (200) planes diffracting X-rays. On the other hand, aluminum-boron films displayed better crystallinity and a preferential (111) texture. Further characterization demonstrated how the sputtering power, the substrate material, and the studied targets affected the films’ morphological and structural. The improvements in morphological and structural aspects that were observed in the films that were obtained via the aluminum-boron target sputtering make this methodology an appealing alternative for metal films manufacturing.
