Abstract

Abstract. Friction Stir Processing (FSP) applies the same technique bases as Friction Stir Welding (FSW) however, instead of joining samples together, the technique modifies the local microstructure of consistent specimens to accomplish precisely and desired properties by surface-modifying the microstructure. As in FSW, the tool prompts plastic deformation during the technique, but rely upon on the selection of system parameters, that is applied enforcement, transverse speed and rotational speed to the performance or specification of the material. In friction processing, the high temperature requested to develop the technique is set up by friction heating at the interface. The cylindrical tool is fitted in a chuck started by a motor that is rotated at high velocity against the work piece which is fitted static. This stress is widened and contacting resistance develops heat to boost the areas to the welding temperature. In this study, varied machining parameters are applied for FSP process. The material selection in this study is based on the specification from the researchers which is using Mg alloy block and Al6061 as a coating on the Mg alloy block. The samples after FSP will be evaluate using hardness and microstructure testing. Furthermore, tests utilizing Brinell Hardness Tester and 3D Measuring Laser Microscope are conducted to further clarify the results by determining high toughness and fine grain structure. From this finding, Friction Stir Processing can upgrade properties such as durability, hardness, corrosion resistance, ductility, and formability without changing the bulk properties of the material.
