Special Issue Information

Dear Colleagues,

In the past ten years, a new technological paradigm, "Hybrid", has begun to appear in the field of coating science and technology. It creates futuristic coating materials with new functions, prestige features, convergence, and fusion features through design and invention of new surface coating materials, which enable the connection of heterogeneous materials, and scales at an electronic, atomic, and molecular structural level, realizing their new features. Additionally, new coating materials were fabricated by hybrid processes combining different processes, which significantly expanded the ideas and visions of coatings and future industry.

The scope of this Special Issue aims to address applied research of hybrid surface coatings and processes, with a focus on the structral applications. We welcome research papers and topic reviews in this field.

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

  • Hard coatings with hybrid composition/microstructure  for tribological applications;

  • Hard coatings with hybrid functions;

  • Hybrid surface processes and hybrid coating processes;

  • Industrial application of hybrid coatings and processes.

In this work, the surface morphology changes of nanocrystalline Cr2O3 film deposited on Si wafer during the heating process were observed in-situ by means of an environmental scanning electron microscope (ESEM). The Cr2O3 film cracked at high temperature due to the cause of thermal stress; the corresponding crack area percentages on the film surface were real-time evaluated using image analysis software (SISC IAS V8.0) based on the principle of gray value analysis. In the meantime, the effects of the heating temperature on the crack area percentage, phase constituents, and grain size of the Cr2O3 film were also studied in detail. The results showed that the percentage of crack area on film surface first increased with the heating temperature rise, and reached the maximum value at around 980 °C, and then gradually declined again. The above trend is closely related to the changes of thermal stress and grain growth in film. In addition, the heat treatment also had a strong influence on the grain size of the Cr2O3 film.

In laser welding and hot stamping Al-Si-coated boron steel, there is a problem that the strength of the joint is lowered due to ferrite formation in the fusion zone. The purpose of this study is to develop an Al-7 wt.% Mn hot-dip coating in which Mn, an austenite stabilizing element, replaces the ferrite stabilizing element Si. The nucleation and formation mechanism of the reaction layer was studied in detail by varying the dipping time between 0 and 120 s at 773 °C. The microstructure and phase constitution of the reaction layer were investigated by various observational methods. Phase formation is discussed using a phase diagram calculated by Thermo-CalcTM. Under a 30 s hot-dipping process, no reaction occurred due to the formation of a Fe3O4 layer on the steel surface. The Fe3O4 layer decomposed by a reduction reaction with Al-Mn molten alloy, constituent elements of steel dissolved into a liquid, and the reaction-layer nucleus was formed toward the liquid phase. A coated layer consists of a solidified layer of Al and Al6Mn and a reactive layer formed beneath it. The reaction layer is formed mainly by inter-diffusion of Al and Fe in the solid state, which is arranged on the steel in the order of Al11Mn4 → FeAl3 (θ) → Fe2Al5 (η) phases, and the Fe3AlC (κ) in several nm bands formed at the interface between the η-phase and steel.
