High-speed waterjet peening technology has attracted a lot of interest and is now being widely studied due to its great ability to strengthen metal surfaces. In order to further improve the mechanical properties of metals, self-excited oscillation pulsed waterjets (SOPWs) were used for surface peening with an experimental investigation focused on the surface topography and properties. By imping...

Over the years, aluminum content in a vehicle part is increasing due to the needs to reduce weight as well as increase fuel efficiency. Most of the cast product in a vehicle part is mostly cast from A356 alloy. It is used because A356 alloy posses’excellent characteristics over other type of alloy such as cast ability, high weight-to-strength ratio, good corrosion resistance and good weld-abili...

the direct synthesis of polyaniline-tio2 nanocomposite coatings on aluminum alloy 3004 (aa3004) surface has been investigated by using the galvanostatic method. the synthesized coatings were characterized by ft-ir, sem-edx, sem and afm. optical absorption spectroscopy reveals the formation of the emeraldine oxidation state form of polyaniline-tio2 nanocomposite. the corrosion performances of po...

Previous studies have yet to show a consistent effect of severe plastic deformation (SPD) processing on the wear behavior different metals and alloys. To fill this scientific gap, study investigated cyclic extrusion compression (CEC) process, as one prominent SPD techniques, AA5052. In addition, microstructure evolution mechanical properties sample before after process were experimentally exami...

The specification of an aluminum alloy for a cast component is based upon the mechanical properties it can achieve. For the designer and purchaser, it is vital to understand that the properties obtained from one particular combination of casting alloy, foundry practice and thermal treatment may not be identical to those achieved with the same alloy in a different foundry or with a different the...

in hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. in this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. specimens of low carbon silicon-free steel with d...

This short review describes various types of anti-corrosion additives of water-soluble metal working fluids for aluminum alloy materials. It is concerned with synthetic additives classified according to their functional groups; silicone compounds, carboxylic acids and dibasic acids, esters, Diels-Alder adducts, various polymers, nitrogen compounds, phosphoric esters, phosphonic acids, and other...
