As for corrosion resistance, horizontally-built samples exhibited the highest pit depth and pit penetration rate compared to the other conditions, which suggested a higher susceptibility to pitting corrosion owing to more strain-hardened particle sites available for corrosive attack. Heat treatment on as...
triisopropoxide and aluminium foil are converted under the reac- tion conditions to an active Lewis acid co-catalyst that activates the nitrile group. These Lewis acidic centres can probably also be gener- ated on the silica support close to the nanoparticles by reaction with Si–OH sites on ...
Aluminium metal matrix composites are widely used in aerospace and automobile industries because of its lighter weight and great mechanical properties like low density, better corrosion resistance, low coefficient of thermal expansion and good wear resistance compared to the convectional metals and alloys...

zinc oxideThe effect of hybrid inhibitor based on Gum arabic (GA, naturally occurring polymer) and zinc oxide on the corrosion of aluminium as galvanic anode in 4 M KOH was studied using hydrogen evolution experiment, electrochemical measurements, and surface analysis method. The results obtained ...
All specimens were mechanically ground for surface standardization using silicon carbide papers with the abrasive material grain size decreasing to 15 µm and, thereafter, polished with aluminium oxide paper with the grain size decreasing to 3 µm. After polishing, the specimens were washed with ...
Keywords: cavitation erosion; bronze-alloys; plasma spray; oxide; metal; laser remelting 1. Introduction The cavitation erosion is a complex phenomenon of interactions of hydrostatic, mechanical, metallurgical, and chemical processes. According to Brennen [1] the cavitation damage is produced by ...
2024-T351 aluminium hat-shaped specimens have been used to experimentally investigate the effect of different initial test temperatures on the strain at which a thermo-plastic instability occurs. A universal testing machine and split Hopkinson pressure bar (SHPB) were used to determine resolved shear ...
The oxygen contribution shown in the RBS spectra is located at the Al/Si interface. This can be clearly assessed as the corresponding narrow peak is shifting towards lower energy channels (higher depths) as the thickness of the aluminium films grows with deposition time. This interfacial oxide ...
