Abstract

The method of carbon nanotubes (CNT) addition to a friction stir welded dissimilar joint has been developed. The CNT agglomerates are produced in shape of paper sheets. CNT sheets added to the gap of butt joint during fixture before friction stir welding. Use of CNT sheets provide ability to measure the weight ratio of CNT in welds. Experimental addition of CNT in Al to Cu dissimilar joint for obtaining 7% CNT in weld was done. XRD study of weld metal shows no formation of carbides as CNT degradation products. SEM study of different weld join parts shows evidence of carbon presence. EDX mapping of carbon in the joint showed that both Al and Cu weld matrix parts have carbon inside.
