Description

14:30 Production of Aluminium Silicon Carbide (Al - SiC) composites by Wire + Arc Additive Manufacture (WAAM)
Kwasi Ayarkwa, Cranfield University, PhD Researcher, Cranfield, Grossbritannien
Structurally graded materials and metallic composites provide optimum properties and cost efficiency which are desirable to the aerospace and automotive industries. An alternative manufacturing option for aluminium particle reinforced composites have been investigated using TIG wire + arc additive manufacture. The study sought to inject SiC particles into an aluminium weld pool with the view to producing aluminium SiC composites. The aim was to find the required velocity of particles on the powder embedding efficiency in molten aluminium. The effect of feeding angle, nozzle position, particle size and type of shielding gas was investigated. In this talk, Kwasi Ayarkwa will discuss this study in more detail as well as sharing the outcomes.
