METHOD FOR MANUFACTURING FRICTION STIR SPOT BONDING PORTION OF METAL MATRIX COMPOSITE

摘要

The present invention provides a method for manufacturing a friction stir spot bonding portion of a metal matrix composite, comprising the steps of: providing a mask; laminating a carbon material on a first metal material using the mask; disposing the first metal material on a second metal material; and bonding the first metal material and the second metal material using friction stir spot welding (FSSW), thereby achieving low-cost and high-efficiency characteristics of NPDS and FSSW and easily manufacturing a composite at a desired location. Furthermore, since NPDS can adjust the amount of laminated carbon powder, it is possible to accurately predict the mechanical property of a spot bonding portion, and since powder is laminated with a sufficient adhesive force, it is possible to manufacture a neat composite.
