ABSTRACT

Department of Science and Technology (DST) has given grant to Dr Shashi Prakash under Science and Engineering Research Board (SERB) for funding of a project.

Project Title: 'Fiber Laser Based Surface Texturing of Aluminum - Mg Alloy for Adhesion Improvement'   

Funding Organisation: Department of Science and Technology (DST) and Science and Engineering Research Board (SERB)

Duration: Two years

Summary: With the growing environmental and emission concerns, Aluminum alloys (Al alloys) have been proved as a suitable alternative to many heavier and energy consuming metals. Subsequently, joining of Al alloys have also been a matter of concern among growing application areas such as automotive and space. While, the conventional welding of Al alloys is difficult and require specific instrumentation and skills, adhesive based joining process is extremely simple in nature. Unlike, bolt-nut fasteners, adhesive based joints remain stable with time and do not increase the considerable weight due to their application. Adhesive based joining of Al alloys is scrapless, emission free, cost effective and do not require any equipment. The process doesn’t put any limitation on design and can be applied anywhere without the need of any post-processing. Aluminum -Mg alloy (AA5754) possesses anti-corrosion properties, recycling potential, non-aging properties and is a very commonly used Al alloy. This work is aimed towards enhancing the joint strength of adhesive bonded Al-Mg alloys (AA5754) using fiber laser texturing as a surface preparation method instead of traditionally used chemical coatings.
