Laser Shock Peening with (LSP) and without protective coating (LPwC) was applied to sensitized AA5083 followed by electrochemical analysis. Potentiodynamic tests indicated a region of increased passivity for the LPwC samples lower corrosion current. Similarly, significantly reduced intergranular rate observed during potentiostatic polarization after treatment while LSP showed only negligible im...

To ascertain the effect of solution pH Na2MoO4 chemical conversion treatment for aluminum/steel joints on corrosion resistance, AA5083 aluminum alloy and AISI 1045 carbon steel were immersed in 50 mM at ranges 8–12 under galvanically coupled condition. Subsequently, diluted synthetic seawater, galvanic resistance connected to was assessed. The number localized damages counted, treated 11 found ...

Abstract TIG welded marine grade AA5083-F/ER5356 and AA5083-F/ER5356+Sc joints were friction stir processed with a pin less FSP tool, to explore the impact of process parameters on mechanical metallurgical characteristics weldments enhance weld strength. The microstructure welds was observed using optical SEM subjected tests like toughness, tensile, microhardness fractography, evaluate strength...

To obtain a high-quality Al/steel dissimilar joint, micro-groove-assisted vortex-friction stir lap welding (MG-VFSLW) process was developed. Through prefabricating micro-grooves on the steel plate surface by laser ablation, mechanical interlock and metallurgical bonding were obtained simultaneously in MG-VFSLW process. The weld formation, interface microstructure, properties, failure mode studi...

Layered alloys and composite materials have become an increasingly popular in industrial development. The roll bonding (RB) process, as a solid phase method of bonding, has been widely used in manufacturing large layered strips. In this study, aluminum alloy (AA 5083) strips were roll bonded at warm and cold temperatures. The effects of the rolling parameters such as the amount of plastic deform...

Abstract Aluminium alloys have been widely accepted in manufacturing lightweight materials with high strength. Therefore, welding aluminium is essential industrial applications to attain complex shapes. In the present work, AA5083 and AA6082 dissimilar were welded using pulsed tungsten inert gas (PTIG) since PTIG reduces defects more than TIG welding. But get better mechanical strength on weld ...
