Abstract Scope |
Magnesium (Mg) based materials have great potential to replace the existing aluminum alloys and steels used in defense, aerospace, and automotive applications due to their excellent specific strength, damping characteristics and impact resistance. Here, we design an ultralow density magnesium/glass microballoon (GMB) syntactic foams with a density of 1.47-1.67 g/cc through Disintegrated Melt Deposition (DMD) technique having extraordinary properties outperforming the existing aluminium and iron syntactic foams in terms of specific strength improvements. Further, the wear resistance of magnesium under dry sliding conditions showed a significant enhancement (~2.5 times) post GMB addition. Abrasion and oxidation were identified as dominant wear mechanisms post worn-surface analysis. Morphology of the worn specimen also indicate that delamination wear which has traditionally limited the competitive advantages of magnesium in safety-critical components for transportation vehicles can be effectively overcome by the development of these proposed syntactic foams which provide unique cushioning effect against the applied load. |
