На основе полученных научных расчетов разработаны практические рекомендации в виде технологического процесса увеличения ресурса двигателей внутреннего сгорания путем использования разработанного состава ТВС. Технологические процессы внедрены в научно-исследовательском институте-полигоне мобильной техники (ИНПОМТ) и Центре трансфера высоких технологий института машин и систем для восстановления трибосистем двигателей внутреннего сгорания. Это позволило увеличить ресурс в 1,5.2 раза, что дает значительный экономический эффект вследствие исключения одного-двух капитальных ремонтов двигателей в процессе эксплуатации.

Abstract
Bilyk A.P. Renewing worn surfaces with tribo-technical regenerating powders. - Manuscript. The dissertation for the degree of Candidate of Technical Sciences in speciality 05.02.04 - Friction and wear in machines, Khmelnitsky National University, Khmelnitsky, 2009.
The optimal composition of new powder for renewing tribo-systems has been found. It's been conducted complete factor experiment whose response functions were wear, ultimate load and welding load. Complex operational, reological and metallic-physical research of surfaces with such covers was conducted applying modern methods. Operational testing showed applicability of new tribo- technical renewing cover to different tribo-systems. Reological testing researched metallic-ceramic cover ageing. Structure of cover, mechanism of non-wearable cover relaxing and its reological specifics during operation were found. Conceptual model that describes behavior of cover is offered. It's been found that optimal operational period of cover is transition interval from Zolya structure to gel-structure. Micro-structural analysis of protective cover allowed developing reological model of structural transitions, in particular modeling transition process from Zolya structure to gel-structure.
Here are given technological and operational recommendations to cover on the friction surface. Such scientific grounding of unique properties of covers will improve implementation of tribo-renewing technologies in the most responsible and scientifically advanced fields.
