Contributed by the Manufacturing Engineering Division of ASME for publication in the JOURNAL OF MANUFACTURING SCIENCE AND ENGINEERING. Manuscript received December 5, 2014; final manuscript received March 11, 2015; published online September 4, 2015. Assoc. Editor: Jingjing Li.

J. Manuf. Sci. Eng 137(5), 051024 (Sep 04, 2015) (6 pages) Paper No: MANU-14-1657; doi: 10.1115/1.4030081 History: Received December 05, 2014

An experimental procedure and test setup are used for investigating effect of using nanoparticle additives to the adhesive on the load transfer capacity (LTC) of bonded magnesium (Mg)–steel (St) single lap joints (SLJ). Investigated variables include the nanopowder material (alumina versus silica), particulate size (20 nm versus 80 nm), and concentration in the adhesive (2.5 wt.% versus 5.0 wt.%). Two different levels of surface roughness on the bonded area are used, namely, sanding the bond area with G60 or G180 sand paper. Test data and scanning electron microscopy (SEM) failure mode analysis are provided.
