The optımısatıon of adhesıve wear behavıor of Almgsi/Sic alumınyum composıte with Taguchı Method

Abstract

Optimization of process parameters is the key step in the Taguchi Method to achieve high quality without increasing cost. The Taguchi method uses the orthogonal arrays to maximize the effect of controllable parameters and to minimize the effect of uncontrollable process parameters. In this study, AlMgSi alloy and matrix reinforced with 5-10 % wt.% SiC particles were perapered by powder metallurgy(PM) method. The wear tests were performed under loads of 10, 20 and 30 N, the rotation speed of 90 rpm, the wear distance of 250, 500 and 1000 m by block on ring test apparatus and the wear losses were calculated. Microstructure examinations at wear surface were investigated by optical microscopy and EDS. Specimens were tested for optical microscopy, EDS and metallographic evaluations. Wear behavior of the composite was investigated to find out effects of operating variables and hardness in terms of the Taguchi approach. The orthogonal array, signal-to-noise (S/N) ratio and analysis of variances were employed to find out the optimal testing parameters.
