“…Accordingly, the tendency for fracture increases, contributing to the nanocomposite powders refinement. This behaviour is consistent with the results reported by Gowda et al [36]. In all powders, uniform distribution of ZnO NPs within the Zn metal matrix was observed, Figure 1(d-f).…”

“…Analysis of the SEM images showed that the mean particle sizes in Zn-25%ZnO, Zn-50% ZnO, and Zn-75%ZnO were 35, 15, and 8 µm, respectively. In the milling process, the powders trapped between the colliding balls and the vial's inner surface are associated with continuous plastic deformation, work hardening, fracturing, and cold welding of the particles [35,36]. The increase in the amount of ZnO nanoparticles alters the cold welding behaviour of Zn particles in a way that the possibility of bonding between the metallic particles decreases, leading to a smaller particle size of the composite powder.…”

The quality of sputtered thin films depends largely on the employed target's chemical, electrical, and microstructural characteristics. This paper explores the application of cold spraying (CS) in manufacturing dense, uniform, and high-performance sputtering targets for ZnO thin films. Zn/ZnO nanocomposite powders with 25, 50, and 75 wt-% ZnO were cold sprayed on Cu substrate. The samples were characterized with respect to their prime properties as well as their performance when used as targets to produce ZnO thin films. By increasing the amount of the nanoparticles in the target, the electrical resistivity and densification of the targets increased at the price of decreased deposition efficiency. Furthermore, the maximum sputtering rate and the most uniform thin film were obtained from the target containing 50 wt-% ZnO. The results confirm the viability of the CS method for manufacturing high-quality Zn/ZnO sputtering targets that can be directly deposited on backplates without additional adhesion treatments.

“…By weighing the components of the composite, which is made of silicon nitride as reinforcement and aluminium alloy 2219 as the base material, we were able to determine their respective proportions of (0%, 3%, 6%, and 9%). Si 3 N 4 is a ceramic material with a low density (3.1 g/cm 3 ) that has excellent mechanical strength and hardness, good thermal and chemical stability, and strong wear and corrosion resistance. Beginning with stirring to reach the melting point of black lead in a coal-fred chamber, the composite is prepared.…”

“…A composite material is composed of two or more main components with chemical or physical qualities that are quite distinct from one another and that, when combined, produce a material with characteristics that are specifc to each of the constituent parts [1,2]. Several factors, including the new material's superior strength, lighter weight, and more afordable price compared to the old materials, may infuence the decision [3]. Aside from worktops, cultured marble, granite, and bathtubs, there are also shower stalls, tanks for storage, and bathtubs.…”

The fabrication of the Al2219 + Si3N4 composites was done by means of stir casting process. The specimen was subjected to microstructural studies. The density of Si3N4 employed in the fabrication of the composites has been evaluated. Generally, the density of the composites increases as the weight percent of Si3N4 increases. TGA and DTA were performed at temperatures ranging from 30°C to 800°C, with some mass loss noted as well as the thermal stability of an AA2219 matrix improved. Under various parameters of applied load, operating duration, and speed, the wear behaviour of the produced aluminium matrix composite (AMC) was examined. Corrosion behaviour was examined using potentiodynamic polarization curve data, and it was discovered that the rate of corrosion decreases with increasing Si3N4 content, adding to the AA2219 matrix. The research work is intended to produce a totally new composite material with various compositions of reinforcement and to investigate their mechanical properties and a result of simulation.

“…Carbon fibres possess high strength (~4000 MPa) and stiffness (~2-4 GPa) but are very expensive than other fibrous materials. In addition to this nanocomposites based on carbon nanotubes are also being projected as probable candidate materials for wind turbine blades [16][17][18][19][20][21]. The glass fibre is the most sought reinforcement material for the composite materials mainly due to cost when compared to that of carbon fibres [22].…”

Rotor blades are the most important part of wind turbine system, which are generally made up of polymer matrix based composites. The performance and lifetime of the wind turbine system often depend of the constituent of composite materials, properties of these materials, design of blades and manufacturing techniques. However the inspections after manufacturing of blades do reveal certain defects which need to addressed and fixed before it is sent for real time operations. Further offsetting usually occurs when closure of two blade halves lead to displacement of aerodynamic suction side from the aerodynamic pressure side. This work is concerned with the two main objectives: one is to repair leading edge cracks in the longitudinal direction, outside the area with existing external root over lamination, the second objective is to how offsetting is measured, evaluated and repaired especially in connection with: overbite and underbite. All these repair procedures were conducted on the glass fabric reinforced polyester blades manufactured by Hand lay-up technique. Until aforementioned repair procedures are not performed, the blades will not be sent to assembly stage. Ultrasonic inspection was conducted as per ASTM standards, ASTM E317 and ASTM E1316.
