Summary: Surface enrichment of Al, Si, and Cr can enhance the high temperature oxidation resistance of alloys. A novel Cr-Si coating process via slurry technique has been developed and demonstrated on two Ni-based superalloys. The addition of Si in the slurry enables the formation of a liquid phase during heat treatment and results in diffusion layers enriched by Cr and Si. The coated samples show lower weight gain during oxidation compared to the uncoated materials.

Summary: This study investigates the effects of chemical composition on the mechanical properties, oxidation resistance, and high temperature tribological properties of AlCrSiTiN coatings. The study finds that both the properties of the coatings and the entire wearing system play a crucial role in the high temperature tribological behavior. However, coatings with poor mechanical properties and oxidation resistance still show inferior high temperature wear resistance.

Summary: The reciprocating sliding wear tests were conducted on TiAlN coating against 316L stainless steel and carbide-free bainitic steel at temperatures of 40, 400 and 800 degrees C. The results showed that material transfer was more significant for the softer stainless steel at lower temperatures, while carbide-free bainite exhibited more material transfer at 800 degrees C. Friction coefficient increased for stainless steel with increasing temperature, but decreased for carbide-free bainite at elevated temperatures due to the formation of an easily sheared iron oxide layer. Additionally, the generation of a thin tribofilm containing aluminium oxide and oxidised transferred material could protect the TiAlN coating against wear at 800 degrees C in the case of stainless steel.

Summary: AlCrWxSiN thin films were synthesized using a hybrid magnetron sputtering process, investigating the effects of increasing tungsten content on film properties and friction and wear behavior at room temperature and 500 degrees C. Increased tungsten content led to more distinct crystal orientations and a denser film growth, resulting in higher hardness and decreased wear coefficient.

Summary: Three nitrides-doped gradient coatings were manufactured and their impact on oxidation performance was discussed. The presence of nitrides was found to inhibit the phase transition of the oxide, increase the oxidation rate of the coatings, and reduce the residual stress in the oxide scale. Proper doping of nitrides is critical for the performance of the coatings.

Summary: This study investigates the mechanical, tribological performance, and high temperature oxidation behavior of Ni- and NiCrAlY-based composite coatings with TiO2/ZnO. The results show that the tribological performance of the coatings is improved by the addition of TiO2/ZnO, particularly with NiCrAlY-based coatings exhibiting the lowest friction coefficient and wear rate at 800 degrees Celsius. The high-temperature oxidation experiments reveal that ZnO diffuses to the surface of the coating with increasing temperature, and the diffusion behavior can be influenced by the metal matrix of the coatings.

Summary: This study investigates the high-temperature oxidation behavior of Cr coatings on Zr alloy under ion irradiation. The results show that irradiation significantly degrades the oxidation resistance of the coatings. Irradiation-induced structural defects accelerate the diffusion of O, Cr, and Zr, and promote the growth of oxides under low-oxygen-partial-pressure conditions. During steam oxidation, the oxide scales develop bubbles and cracks due to the formation of Zr(O) phases along the oxide-metal interfaces.

Summary: The atomistic mechanisms of damage initiation during high velocity impacts on a W surface have been investigated using molecular-dynamics simulations. The results show that high velocity impacts cause plastic deformation, breakup, melting, and vaporization of the target material. The crater volume increases linearly with the kinetic energy, and the total dislocation length depends on the impactor size.

Summary: Undoped AlxGa1_xN epilayers with different thicknesses were grown on sapphire substrates using MOCVD. SiN nano-mask was deposited on the substrate to reduce threading dislocation density. The surface coalescence degree affected the physical and nanomechanical properties. Decrease in threading dislocations resulted in slight decrease in physical properties but improved nanomechanical properties. Defects did not significantly affect the plastic deformation capacity of AlxGa1-xN films.

Summary: The study investigates the effect of adding Ag on the tribological performance of a CrAlN coating system at room and high temperatures. The results show that Ag addition can lower the coefficient of friction, but also degrades the specific wear rate. A small amount of Ag exhibits the best performance at room temperature, while high concentrations of Ag have a detrimental influence on the coating's properties.

Summary: This study investigates the structure evolution of a multilayered TiSiN/TiN(Ag) coating with heating and oxidation. The results show that the coating has a multilayered structure, with TiSiN layer consisting of Ti-Si-N solid solution grains and amorphous a-SiNx phase, and TiN(Ag) layer consisting of fcc TiN and Ag crystalline phases. Oxidation starts at 800 degrees C, forming rutile-TiO2. The oxidized part of the coating is Ag depleted, except for the top layer containing some Ag clusters. Ag diffuses towards the surface from the oxidized zones. There are no signs of recrystallization or structural changes in the cross-sectional analysis, except for stress relaxation in the non-oxidized part after annealing at 800 degrees C. Ag redistribution or diffusion is not found in the non-oxidized part, suggesting the effectiveness of the multilayered design in mitigating uncontrolled Ag migration towards the surface.

Summary: Pathogens can survive on surfaces for a few days and can propagate through them, making surfaces a major source of pathogen transmission. Antimicrobial surfaces, created using resilient, mass-produced polymers with embedded antimicrobial nanoparticles, show promise in preventing and mitigating pathogen transmission. In this study, a 6 nm thick layer of silver nanoparticles was deposited on a polycarbonate substrate and thermally annealed to embed the nanoparticles into the polymer surface. The incorporation of silver nanoparticles had a significant impact on the antibacterial capacity of the polymer surface, inhibiting the growth of both Gram-positive and Gram-negative bacteria. The surface-engineering process used in this study is cost-effective and scalable.
