摘要：
The objective of this study is to improve surface hardness of 7178 aluminum alloy using the ball burnishing process. The effect of the main burnishing parameters on the objective function was examined using full factorial design and analysis of variance (ANOVA). The main parameters were found as burnishing force, feed rate and number of passes among four controllable factors that influence the surface hardness in ball burnishing process. Optimal ball burnishing parameters were determined after the experiments of the Taguchi's L9 orthogonal array. As result, the optimal burnishing parameters for surface hardness were the combination of the burnishing force at 200 N, number of passes at 4, feed rate at 0.25 mm/r.
