      Friction and Wear Behavior of Polyethylene Matrix Composites.

AB  - The aim of this research was to analyze the effect of inorganic additives on the 
      tribological properties of the high-density polyethylene (HDPE) matrix composite 
      surface. Titanium (Ti) and hexagonal boron nitride (hBN) were added in different 
      mass fractions. The samples were produced by pressing a pre-prepared mixture of 
      granules. The composite samples with the following mass fractions of additives 
      were fabricated: 5% hBN, 10% hBN, 28% Ti-2% hBN, 23% Ti-7% hBN, and 20% Ti-10% 
      hBN. An even distribution of individual additives' concentrations was confirmed. 
      Observations of morphology, surface topography, hardness, and tribological 
      measurements were conducted using reciprocating motion tests with the 
      "pin-on-flat" and rotational tests with the "pin-on-disc" configuration. 
      Subsequently, microscopic observations and measurements of the wear track profile 
      were carried out. Additionally, geometry parameters of the contacting elastic 
      body were calculated for various counter-samples. It was found that the Shore D 
      hardness of samples containing Ti and hBN increased with the Ti content, while 
      the coefficient of friction (COF) value decreased. The addition of hBN alone did 
      not significantly affect the hardness, regardless of the ratio, while the COF 
      increased with the increasing hBN content. The COF value doubled with the 
      addition of 10% hBN (COF = 0.22), whereas the addition of 90% Ti-10% hBN resulted 
      in a decrease in the COF value, to COF = 0.83. The highest hardness value was 
      obtained for the sample containing 28% Ti-2% hBN (66.5), while the lowest was for 
      the sample containing 10% hBN (63.2). The wear track analysis, including its 
      height and width caused by deformation, was detected using a focal 
      differentiation microscope and scanning electron microscopy. Additionally, EDS 
      maps were generated to determine the wear characteristics of the composite.
