Abstract

Magnesium alloys, which are widely used in automotive, aerospace and manufacturing industries as lightweight and high strength materials, have some limitations due to inadequate corrosion resistance and low surface quality. In order to overcome these limitations and to improve the surface properties in particular, the magnesium alloy ball correction process is applied with different parameters (burnishing force, number of passes, feed rate and burnishing speed). The Taguchi method was used to reduce the number of experiments and the better burnishing conditions were determined considering the S/N ratios. Data obtained from the experiments were analyzed by variance analysis (ANOVA) method; it is seen that the feed rate, the burnishing speed and the number of passes have a significant effect on the surface roughness when the analyzed factors and their interactions are considered in the analysis result. In terms of the results of the surface roughness tests, it has been found that the feed rate and burnishing force are important parameters for increasing the surface quality. When the low feed rate and high force parameters are selected, the better surface roughness value is achieved.
