Corrosion Behaviour of 6061 Al-SiC Composites in KOH Medium

Influence of TiC particulate reinforcement on the corrosion behaviour of Al 6061 metal matrix composites

Aluminum matrix composites (AMCs), reinforced with ceramic particulates, have significant applications in the field of aerospace, marine, automobiles, sports and recreation. Al-TiC particulate composite has better potential for high-temperature applications. The corrosion behaviour of Al 6061-TiC particulate composites prepared by stir casting route, has been explored in chloride medium using e...

AN INVESTIGATION ON CORROSION BEHAVIOUR OF A356-10 VOL.% SiC COMPOSITES IN HCl SOLUTIONS

In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...

Corrosion Polarization Behavior of Al-SiO2 Composites in 1M and Related Microstructural Analysis

The composites combining aluminum and silica nanoparticles with the addition of tetramethylammonium hydroxide (Al-SiO2(T)) and butanol (Al-SiO2(B)) as mixing media have been successfully fabricated. Corrosion behavior of Al-SiO2 composites before and after exposure in 1M NaCl solution was examined using potentiodynamic polarization (Tafel curve analysis). The st...

CORROSION BEHAVIOUR OF Al-Li-Cu-Mg ALLOY 8090-T651

Stress-Assisted Corrosion of Aluminum 6061 in Basic Solution

Caustic stress corrosion cracking has only been superficially examined in aluminum alloys. In caustic (basic) environments, the inherent, protective oxide layer becomes soluble on aluminum and allows for further degradation. The purpose of this study is to observe the effect of a strong base solution (sodium, hydroxide, sodium hypochlorite, sodium silicate, pH ~12) on the strength and stress-st...
