“…In recent years, transition metal suldes represented by the MS 2 class have been widely used in the eld of lubrication due to their special structures and excellent physical and chemical properties. 48 MS 2 has a typical three-layer structure, that is, its upper and lower layers are densely packed hexagonal sulfur atoms with a metal M layer interposed between them, and the triangular atoms of the sulfur atoms surround the M atoms. In the crystal structure, the M-S atoms are covalent bonds, and the adjacent S-M-S layers are connected by weak van der Waals forces.…”

“…Most of these coatings were developed with lubrication as the main purpose. Furlan et al [17] presents a good overview of different MMC coatings containing MoS 2 that have been developed for tribological applications. Stankovic et al [18] studied the codeposition of MoS 2 particles and copper ions.…”

In this work, a superhydrophobic coating was developed by composite electrodeposition of MoS 2 particles in a copper matrix. AISI 316L stainless steel and N80 carbon steel, with a thin electrodeposited Ni layer to improve adherence of the coating, were used as substrates. Different operational parameters of electrodeposition were studied in order to produce the highest possible contact angle. We demonstrate that, using this method, a coating with a hierarchical structure with feature dimensions in the range of µm to nm is obtained, with advancing contact angle values up to 158.2 • and a contact angle hysteresis equal to 1.8 • . To study the coating composition energy dispersive X-ray, X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry were performed. Moreover, potentiodynamic polarizations were performed in H 2 SO 4 , NaCl and NaOH solutions to study the corrosion behavior of the coating. As a control, a sample coated only with MoS 2 particles by means of electrophoretic deposition was produced. The results show that the composite coating can be used in applications where copper is used for corrosion protection, with the addition of the desirable effects of its superhydrophobicity. known as the "lotus effect" [5]. In this case, both θ A and θ R will have a high value and the contact angle hysteresis will be low. If the sample presents a high θ A but the water droplet is in a Wenzel state (Figure 1b), in full contact with the surface, θ R will be very low, and the droplet will not roll freely on the surface. Despite the high θ A , this is not considered a superhydrophobic surface. This will be indicated by a low θ R and, consequently, a high contact angle hysteresis.

“…The addition of low density material has certain advantages and disadvantages. For example, MoS 2 is one of the solid lubricants mainly added with Cu to improve the machinability of the material but it undergoes reaction with the base material and also acts like a poor lubricant [19]. Similarly, the addition of Al 2 O 3 increases the Any further distribution of this work must maintain attribution to the author(s) and the title of the work, journal citation and DOI.…”

This research paper describes the enhancement of mechanical, wear and corrosion behaviour of the Copper (Cu) matrix composite by reinforcing Fly ash (FA) and Tungsten (W). The main objective of this study was to reduce the weight and cost of the hybrid composites. The weight percentage of low density material (FA) was kept constant at 6% and samples were prepared by the addition of W in weight percentages of 3, 6 and 9 in the Cu matrix. The characterization of the hybrid composites was studied using a Scanning Electron Microscope (SEM) and Energy-dispersive spectroscopy (EDS). The micrographs revealed the uniform distribution of W and FA in the Cu matrix. From the mechanical characterization, it was identified that there is an increase in microhardness and compressive strength with the addition of W particles. It can be understood that the W particles occupy substitutional type reinforcement and FA particles occupy interstitial type reinforcement in the Cu matrix. The Wear behavior and its mechanism were studied using worn surface SEM micrographs. It was observed that the lowest specific wear rate was recorded for the hybrid composition of Cu-6FA-6W. Electrochemical polarization test and Electrochemical Impedance Spectroscopy (EIS) study revealed that Cu-6FA-9W shows higher corrosion resistance in both 1 N HCl (256.593×10 −4 Ω cm 2 ) and seawater media (219.855×10 −4 Ω cm 2 ) than pure Cu.
