Antifrictional nanocomposites based on chemically modified UHMWPE. Part 3. Comparison of modification effect of compatibilizers on mechanical and tribotechnical properties

Increasing the wear resistance of ultra-high molecular weight polyethylene by adding solid lubricating fillers

“…During the testing of these composites, the fixed abrasive particles cut the matrix, and soft polytetrafluoroethylene cannot "protect" it (the grooves in the wear surface of the compositions are comparable with those in the pure UHMWPE). Apparently, the soft polytetrafluoroethylene only facilitates the sliding of abrasive paper along the surface of specimens under wearing [5].…”

Polymer Composite Materials Based on Ultra High Molecular Weight Polyethylene Matrix Filled by Alumina Powders

“…UHMWPE is a material with high performance properties such as specific strength, stiffness, fatigue (cyclic) resistance, high wear-resistance at low temperatures (up-200°C), ultralow friction factor, high impact strength and resistance to hostile environments, weather impacts and radiation exposures. [1][2][3][4][5] The unique material properties, ease of processing and a variety of applications allow widely using UHMWPE for production of various articles in tribology applications, under abrasive action and in hostile environments. S.V.…”

“…S.V. Panin and Co [4][5], suggested modifying of UHMWPE with alumina to improve the performance specifications of the material (strength, hardness and melting temperature). The aim of the article is to introduce the investigation of regularities of compaction and microstructure and properties formation of ultra-high molecular weight polyethylene (UHMWPE) modified by ceramics А1 2 О 3 particles of different particle size as well as methods of UHMWPE production In the work the following tasks were solved: the development of theoretical models describing the processes of consolidation and structurization of PCM, the study of morphology of the source powders, the research of the effect of agents A1 2 O 3 on the technological and physicalmechanical characteristics of PCM.…”
