Investigation Of Effect of Variables on The Wear Loss of Ceramic Composites Using Response Surface Methodology

Abstract

Fused silica ceramic composite with combinations of Boron nitride and Silicon nitride were fabricated using gel casting, a near net shape fabrication technique. Methyl acryl amide (MAM) and N, N1-methylene bis acryl amide (MBAM) were used as monomers. After successfully preparation of ceramics samples, wear behavior of samples is investigated on Pin-On-Disk Tribometer and wear loss is found at different parameters. A Mathematical model was developed to determine the effects of load, sliding distance and sliding speed on wear loss. The influence of the surface methodology using central composite face centered design with six center points. The optimal values form minimum wear loss and parameter shave been presented. Moreover, the Mathematical model has been modified using Artificial Immune System: Negative Network Selection algorithm in Matlab and the optimum input parameters along with the corresponding values of minimum wear loss have been studied. A validation test on Pin-On-Disc Tribometer has been carried out and the comparison between the theoretical responses and experimented responses, based on optimum input parameters of both RSM and Matlab, has been made as well as the errors between the have been presented.
