Abstract
Taguchi methodology was implemented to optimize and evaluate the effect of process parameters such as the applied pressure and time of holding on the tribological properties of ultra-high molecular weight polyethylene (UHMWPE) nanocomposite reinforced with different loadings of silicon carbide (SiC) nanoparticles. An L9 orthogonal array was used to design experimental matrix in terms of pressure, holding time, and the loading of SiC. UHMWPE/SiC nanocomposites were synthesized via ultrasonication and hot pressing. Pin on disk wear tests were carried out on the composites to evaluate the tribological properties such as specific wear rate and coefficient of friction. Friction and wear response were analyzed using analysis of variance and regression models. The effect of each parameter and optimal process parameters that result in minimum friction and specific wear rate were determined. The confirmation tests carried out verified the validity of the developed experimental design model.
