Relevance:

High performance polymeric materials such as PEEK and PTFE are considered as a potential tribological material for reciprocating mechanical systems due to their self-lubricating properties, especially under conditions of high loads and sliding speeds. PEEK and PTFE have a number of exceptional properties such as exceptional thermal stability, excellent mechanical properties, and high wear resistance. Therefore, these remarkable characteristics make them potentially superior wear material candidates compared to other types of polymers. However, pure PEEK and PTFE generally exhibit poor wear resistance, which limits their use in friction applications. Therefore, PEEK and PTFE must be modified to increase service life through reinforcement technology or surface modification during the actual application. One of the promising ways to modify the surface of polymeric materials is electron beam processing, which has great potential.

Target:

Development of a technology for electron-beam modification of polymeric materials, which makes it possible to increase their wear resistance, as well as the study of the regularities of structural and radiation-chemical transformations in the surface layers of PEEK and PTFE during non-vacuum electron beam processing.

Expectation:

1. The structure, chemical composition, physicochemical characteristics, physico-mechanical and tribological properties of polymeric materials will be investigated depending on the mode of electron irradiation.
2. Optimum modes of non-vacuum electron-beam processing of polymeric materials will be determined, providing high wear resistance of the surface layer.
3. Regularities will be established for the formation of the structure and properties of the modified surface layer of polymeric materials during electron beam processing.
4. Bench testing of parts made of polymer materials treated with an electron beam will be carried out.
5. On the basis of the data obtained, innovative proposals will be formulated with the prospect of introducing the developed radiation technology into production.
