Summary: The study investigated the potential of using the duplex system plasma nitriding + CrN coating as an alternative to hard chrome plating, evaluating the mechanical and tribological properties, as well as surface texture of various surface treatments. The PN + CrN duplex system showed higher hardness and better tribological properties compared to hard chrome, but had a slightly worse surface texture.

Summary: The study found that plasma nitriding applied before PVD significantly improved the corrosion and tribocorrosion resistance of PVD CrN, TiN and AlTiN coatings on AISI 4140 steel. Additionally, it was concluded that duplex treated low alloy AISI 4140 steel could be a candidate instead of stainless steel in tribocorrosion conditions for the marine environment.

Summary: This study investigates the tribocorrosion behavior of untreated, plasma nitrided, Ti-DLC coated, and duplex treated AISI 316L stainless steel. The results show that the wear mechanism causes much more damage than corrosive effects. Generally, the wear and tribocorrosion performance of the treated samples increase compared to the untreated sample, thanks to the layers formed on the surface. The best tribocorrosion resistance is observed in the duplex surface-treated sample.

Summary: In this paper, a low-temperature plasma oxy-nitriding technology with two-stage processes was developed to address the issues of high nitriding temperature and long nitriding time in conventional plasma nitriding technologies. Compared to conventional plasma nitriding technology, this new technology can achieve a thicker permeation coating. This is because the oxygen introduction in the first two-hour oxy-nitriding step can break the continuous TiN layer, facilitating the diffusion of O and N into the titanium alloy and forming an inter-connected porous structure under a compact compound layer.

Summary: In this study, plasma nitriding has been applied to electron beam melted Ti6Al4V titanium alloy, and the results showed that the plasma nitriding-treated sample exhibited better corrosion resistance in natural seawater than the untreated sample. This was attributed to the formation of a 16 μm compound layer, which effectively prevented the intrusion of harmful ions and enhanced the corrosion resistance of the electron beam melted titanium alloy.

Summary: The influence of gas pressure on the plasma nitriding process of surface nanocrystalline TC4 titanium alloy prepared by shot peening was investigated in this study. The results showed that appropriate gas pressure during nitriding could lead to a thicker nitriding layer and higher hardness. Additionally, the gas pressure was found to affect the formation and migration of active nitride particles.

Summary: The study investigated the wear and corrosion behavior of duplex TiTiN bilayer coatings obtained by cathodic arc deposition combined with ion implantation (PBII&D) on plasma nitrided AISI 316 L stainless steel. The results showed that PBII&D coatings had better adhesion and corrosion resistance, while commercial PVD TiN coatings had the smallest wear volume loss.

Summary: Magneto-rheological (MR) materials are smart materials that can respond reversibly and quickly to an external magnetic field. This study aimed to determine the mechanical properties of MR materials for shear behavior under harmonic loading. Various parameters such as matrix hardness, powder type, magnetic field, frequency, and deformation were investigated. The results showed that composite materials with Shore 2 hardness and SQ magnetic powder exhibited the most suitable properties. However, there is a lack of research on comparing different hardness values and examining features such as MR effect, storage modulus, and loss modulus under magnetic field conditions.

Summary: In this study, Cu-Cr-Zr alloy specimens were subjected to aging heat treatment at 500 degrees C for different durations. Three different coating processes were applied using physical vapor deposition method. The specimens were then tested for mechanical properties, wear resistance, electrical conductivity, and structural analysis. The results showed that the specimens aged for 4 hours at 500 degrees C had the highest hardness and strength values. Furthermore, the specimens with duplex surface treatment exhibited better wear resistance and electrical conductivity.

Summary: In this study, the influences of anodic coating process parameters on the surface roughness and coating thickness of Aluminum 5754 alloy were investigated using Central composite design. The competence of the mathematical models and the importance of the regression coefficients were analyzed by ANOVA. The results showed that the maximum coating thickness of 29 μm was obtained at 16 V voltage and 30 min anodizing time on the surface prepared with 1200 grit size, while the lowest surface roughness value of 0.676 μm was obtained at 8 V voltage and 10 min anodizing time on the surface prepared with 1200 grit size.
