Abstract

FRICTION STIR processing (FSP) is a surface improvement method. This process has been developed for facilitating the refinement of microstructure, improving the MECHANICAL PROPERTIES and producing the surface composite. The aim of this study is producing the surface COPPER-based nanocomposite with reinforcing SiO2 particles by FRICTION STIR processing for improving the MECHANICAL PROPERTIES. Therefore, 56 mm/min fixed traverse speed and 500, 710, 1000 rpm rotational speeds were used. Microstructures of samples were studied by optical and scanning electron microscopes. Optimum sample had a rotational and traverse speed of 500 rpm and 56 mm/min, respectively. The MECHANICAL PROPERTIES of the produced surface composite such as MICROHARDNESS and tensile strength were evaluated and then compared with the base metal. The results of the mechanical tests showed that the MICROHARDNESS and tensile strength were improved in comparison with base metal. The MICROHARDNESS of the base metal and optimum sample were about 84Hv and 121 Hv, and tensile strength of them were 218 MPa, and 227 MPa, respectively. Finally, WEAR properties of surface composite were investigated. The results exhibited better WEAR behavior and also 28 percent decrease in friction coefficient of produced composite compared with the base metal.
