Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to this Special Issue, "Functionally-Graded Nanocomposite Surfaces".

This Special Issue will focus on emerging challenges and developments of multifunctional nanocomposite coatings. We will devote special attention to studies in which physico/chemical properties have been functionally graded and optimized.  Functionally-graded materials have been known of since the space race, back in the 1960s, and have been defined as materials in which the chemical and structural composition changes over their entire volume. Nowadays, thanks to our current understanding, technology and control over the micro and nanostructure of materials, we can apply all this knowledge at the nanoscale; the so-called functionally-graded nanocomposites materials (FGNM).

Although several studies have investigated the bulk properties of FGNMs (tribological, electrical, thermal, etc.), not much attention has been devoted to their surface properties, leaving a broad range of potential applications unexplored. Therefore, in this Special Issue, we aim to gather a collection of studies devoted to the understanding and tailoring of FGNMs surfaces, in which both the nanocomposite structure and surface phenomena are at the center of study and discussion.

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

  • Synthesis, deposition and characterization of nanocomposite FGNMs:
    • Films/coatings
    • Nanofiber/patterned surfaces
    • Oxides/carbides/nitrides/metals/polymers/hybrid materials
  • Functionally-graded high entropy alloys (HEAs)
  • Functional studies of FGNMs surfaces:
    • Tribological/mechanical studies
    • Biocompatibility/scaffolding
    • Corrosion/electrochemical/catalytic
    • Thermal and diffusion barriers
    • Electronic/conductive/magnetic/dielectric
    • Modelling/theoretical

The heat-reflective coating for asphalt pavement is a functional layer applied on pavement surfaces to reduce heat storage in the pavement via reflecting sunlight, thus inhibiting pavement temperature rise. The objective of this study was to analyze the environmental thermal effect of the self-developed reflective coating, namely, functionally graded nanocomposite reflective coatings, for asphalt pavement. The thermal effects of heat-reflective coatings were compared and analyzed based on field tests. A heating model of the atmosphere layer near the road surface was established. Moreover, the influence of urban road temperature on the thermal comfort of the human body was analyzed. Results showed that the radiation heat of all heat-reflective coatings decreased around two-thirds, and the convective heat decreased nearly 50% when compared with the control asphalt pavement, and the temperatures of the pavement itself and the atmosphere layer were lowered. Additionally, the heat-reflective coating improved the thermal comfort of the human body. This indicated that the heat-reflective coating reduced ambient temperate and relieved the urban heat island effect (UHI) as well as improved the environmental thermal effect. Full article

Functional gradient materials (FGMs) have tremendous potential due to their characteristic advantage of asymptotic continuous variation of their properties. When an FGM is used as a coating material, damage and failure of the interface with the substrate component can be effectively inhibited. In order to study the dynamic crack propagation in FGM coatings, a new method, peridynamics (PD), was used in the present study to simulate dynamic fractures of FGM coatings bonded to a homogeneous substrate under dynamic loading. The bond-based PD theory was employed to study crack propagation and branching in the FGM coating. The influences of the coating gradient pattern, loading, and the geometry and size of the structure on crack curving and propagation under impact loading were investigated. The numerical results show that different forms of the elastic modulus of graded material, the geometry of the structure, and the loading conditions have considerate effects on crack propagation in FGM coatings, but a specific form of elastic modulus had a limited effect on the dynamic fracture of FGM coating.

In this study, the buckling of functionally graded (FG) nanoporous metal foam nanoplates is investigated by combining the refined plate theory with the non-local elasticity theory. The refined plate theory takes into account transverse shear strains which vary quadratically through the thickness without considering the shear correction factor. Based on Eringen’s non-local differential constitutive relations, the equations of motion are derived from Hamilton’s principle. The analytical solutions for the buckling of FG nanoporous metal foam nanoplates are obtained via Navier’s method. Moreover, the effects of porosity distributions, porosity coefficient, small scale parameter, axial compression ratio, mode number, aspect ratio and length-to-thickness ratio on the buckling loads are discussed. In order to verify the validity of present analysis, the analytical results have been compared with other previous studies. Full article

One area of constant interest in many fields of industry is development of functional multilayer coatings that possess excellent performance characteristics. That is why in our brief review the results of studies of structure and properties of multilayer structures based on binary nitrides of transition or refractory metals obtained by various physical-vapor deposition (PVD) techniques are presented. The influence of substrate temperature, substrate bias voltage, bilayer thickness and interface boundaries on the structure of coatings and their properties, such as hardness, plasticity, wear and corrosion resistance, are discussed in detail. This review may be useful for students and growing community of researchers interested in the synthesis-structure-properties relationship in multilayer coatings based on metal nitrides. Full article
