The influence of additive nature as well as its ratio on the rheological, tribological and technological properties of blends based on ultra-high molecular weight polyethylene has been determined. The energy costs impact in the polymer blends processing has been studied. It is shown that the rheological and tribological properties of the samples have a complicated dependence, which is determined by inhomogeneity of the system. The paper takes into consideration the influence of the friction coefficient of material and the viscosity of its melt on energy costs during processing by injection molding or extrusion

Purpose This paper aims to focus on studying the addition of nano-tungsten disulfide (WS2) on fretting wear performance of ultra-high-molecular-weight-polyethylene (UHMWPE). Design/methodology/approach In this study, the effect of WS2 content on fretting wear performance of UHMWPE was investigated. The fretting wear performance of the UHMWPE and WS2/UHMWPE nanocomposites were evaluated on oscillating reciprocating friction and wear tester. The data of the friction coefficient and the specific wear rate were obtained. The worn surfaces of composites were observed. The transfer film and its component were analyzed. Findings With the addition of 0.5% WS2, the friction coefficient and specific wear rate increased. With the content increased to 1% and 1.5%, the friction coefficient and specific wear rate decreased. The lowest friction coefficient and specific wear rate were obtained with the addition of 1.5% nano-WS2. Continuingly increasing content, the friction coefficient and wear rate increased but lower than that of pure UHMWPE. Research limitations/implications The research indicated the fretting wear performance related to the content of nano-WS2 with the incorporation of WS2 into UHMWPE. Practical implications The result may help to choose the appropriate content. Originality/value The main originality of the research is to reveal the fretting behavior of UHMWPE and WS2/UHMWPE nanocomposites. It makes us realize the nano-WS2 had an effect on the fretting wear performance of UHMWPE.
