“…There are a variety of additional cement materials available that can be used to produce coral concrete. These materials are silica fume, fly ash, volcanic tuffs, and other geo-polymers [18][19][20][21][22][23][24]. Apart from this, metallic and non-metallic fibers, organic and inorganic fibers can be considered for coral concrete.…”

The worldwide interest in coral concrete stems from its use in reef engineering, where it is a composite material made by combining saltwater and coral. This analysis examines the components, mechanical characteristics, and durability of coral concrete. The micro hardness of the interfacial transition zone in coral concrete is significantly greater than that of normal concrete. However, it is found that the coral concrete has less compressive strength than standard concrete hence, the durability of standard concrete is also longer than this concrete. However, the addition of fibres to coral concrete improves the splitting tensile strength and flexural strength significantly. Inadequate cementation of the components hinders the performance of coral concrete because of the porous and brittle nature of coral aggregates. Further investigations can be carried out for underwater engineering applications and sea constructions by selecting appropriate coral aggregate type and developing mix design procedure to produce the high-strength coral concrete.

“…As a result, it projected the entire machining cost per component to be Rs.23.12 in Indian rupees. In the study carried out by Wagri et al [19], it was confirmed that the hardness of a material significantly impacts its machinability, which in turn impacts the component's surface quality, power consumption, and cutting tool life [20]. However, the current machining fluid employed in the industry, e.g., soluble oil, is not environmentally friendly.…”

The effects of various machining fluids on the surface hardness and corrosion behaviour of Al6061 alloy were investigated in this study. The study employed the two-step method to develop the machining fluid containing TiO2 nanoparticles with various percentage concentrations. The corrosion study media consist of soluble oil (sample A1), mineral oil (sample A2), 0.2-g/l-TiO2 nano-mineral machining fluid (sample A3), 0.4-g/l-TiO2 nano-mineral machining fluid (sample A4) and 0.6-g/l-TiO2 nano-mineral machining fluid (sample 5). The corrosion study was carried out with Potentiodynamic corrosion and polarisation resistance techniques. After the corrosion study, the SEM and EDS were employed to investigate the microstructure and elemental composition of the machining fluid effects on the Al6061 alloy, and the Vickers micro-hardness machine was used to test the surface hardness of the normal face region that was exposed to the corrosion study. The results show that the soluble oil has a high corrosion rate, with the list polarisation resistance rate compared to the other machining fluid employed in this study. Furthermore, the 0.6-g/l-TiO2 nano-mineral machining fluid has the lowest corrosion rate of 0.115 (µm/year) and the highest polarisation resistance of 1.543 (MΩ). The study concluded that the 0.6-g/l-TiO2 nano-mineral machining fluid is viable for the machining process.

Sheet metals such as titanium alloys, steel alloys, and aluminum alloys are significant materials due to their importance among everyday life products as well as high-strength applications in aircraft, ships, automobiles, construction, military, and marine purposes. Recently, laser cutting is one of the best and fastest non-conventional methods to cut sheet metals, so it is necessary to understand how laser cutting parameters affect cutting quality. A comprehensive review was presented to investigate how laser cutting parameters affect the cut surface and kerf quality and which parameters affect cutting quality the most. An overview of the advantages of laser cutting when compared to other methods of machining was presented. In addition, a description of the laser cutting method and the different sources of laser were presented with clearing the range of thicknesses of the cut material for each source and their advantages. Also, a description of the properties and the applications of the studied materials were discussed. The performance parameters ofcutting were illustrated in detail by graphs and equations. The research analysis and discussion were discussed in such organized details by tables and graphs which show the full classification of the studied papers. It was found that the best conditions to obtain low surface roughness, small HAZ width, small kerf width, and small kerf angle are using low laser power, high cutting speed, medium gas pressure, high standoff distance, medium pulse frequency, medium pulse width, small nozzle diameter, small thickness, and nitrogen as an assist gas.
