Modeling of Wear Behavior of AA7068/TiC Metal Matrix Composites Using Fuzzy Logics and Response Surface Model

摘要

Metal matrix composites are finding it increasing applications in various engineering fields such as aerospace, automobiles, and other industries due to its low density and excellent wear resistant. This paper presents the use of fuzzy logic modeling process parameters in a wear testof AA7068/TiC, with various weight fractions of reinforcement varied from 0 to 10 wt.% in steps of 2 wt.% and the test specimens was prepared as per ASTM standards. The wear behavior was investigated by performing dry sliding test on pin-on-disc tester. Experiments are planned and conductedas per central composite design (CCD). The process parameters used are wt.% of TiC, rotational speed (N), sliding velocity (V), and applied load (P). The output response considered in the investigation is wear. Fuzzy rule based model is developed for correlating the processparameters with wear. The results indicated that the model can be effectively used for predicting the wear in dry sliding of MMCs.
