A study was conducted to identify the threshold concentrations of chloride contaminant in an inhibited engine coolant on three different metallic substrates—cast iron, cast aluminum, and brass. All three metallic systems showed a reduction in the breakdown potentials during potentiodynamic polarization ...
Concrete structures, particularly highways and bridges, typically utilize metallic reinforcement members embedded therewithin to provide stability and additional strength to the concrete, as well as to enhance the ability of the concrete to withstand shear forces. These reinforcements are used in a variet...
Currently, magnesium becomes the third most-used metallic material in automobiles [49]. Major automotive applications incorporate powertrain systems, chassis, and body structures, such as instrumental panel, engine cradle, bracket, transmission case, seat frame, and front-end structure [19], [50]. ...
Metallic materials are ubiquitously used in hypersonic vehicles – as nose and wing leading edges, control surfaces, and engine inlets – due to their tendency to their damage tolerance and manufacturability. These components need to withstand extremely high heat fluxes and thermal strains, which deman...
abundant element in the earth's crust (2.7%). Although sometimes perceived as exotic, magnesium alloys have been used for decades in both motorsport and production vehicles. For example, VW began using cast magnesium crankcases for its 1961-model, 40 horsepower flat four, air-cooled engine. ...
It can be seen that milling, turning and drilling are the processes mostly used in primary machining operations, and the tools for these operations capture almost 87% of the total tooling market. In terms of the type of cutting material, cemented carbides capture one half of the market, ...
In the compressor section, axial or radial according to the flow vein shape, where air taken into the engine by the fan is compressed, the materials generally used are Fe-, Ni- and Ti-based heat resistant alloys. The compressor can reach temperatures up to 1000 °C and the air pressure ...

2. Nuclear Industry: Used in nuclear reactors for fuel rod cladding, reactor vessel components, and coolant system piping due to their low neutron absorption cross-section and excellent corrosion resistance in high-radiation environments. 3. Aerospace Industry: Employed in aircraft hydraulic systems, ...
Graphene is not the first nanocarbon, or indeed nanomaterial, to emerge out of the lab and, given that most applications see graphene used as an additive, understanding the competitive market is essential. Carbon black is the incumbent conductive carbon powder, of which there are numerous grades...
