Optimization of Process Parameters During Dry Sliding Wear of Aluminum-Based Composites Using Response Surface Methodology
摘要
Composites are a combination of two or more materials, each of which has unique desired properties that affect the absolute properties of the composite. The main goal of aluminum composite production is to improve the properties of the matrix material. Dry wear analysis has been conducted on LM13/B4C/graphite composite on a pin-on-disk tribometer apparatus supplied by DUCOM (TR-20LE). Response surface methodology (RSM) was cast-off for experimentation, and corresponding pin temperature has been calculated for the fabricated composites. Three input process parameters, namely applied load, sliding speed, and time, have been considered for the present effort. A mathematical model was developed to analyze the effect of the above parameters on pin temperature. The best presentation of process parameters has been assessed by RSM desirability. It has been established further appropriate forminimizing the pin temperature and delivering a concentrated desirability. Importance and relevancy of the proposed model has also been performed with ANOVA. The proposed model delivers more precise results and the wear performance with minimum pin temperature of the cast composites enhanced. According to the data, applied load had the greatest influence, followed by sliding speed and time.
